.SH DESCRIPTION
|
|
.B mplayer
|
|
is a movie player for Linux (runs on many other platforms and CPU
|
|
architectures, see the documentation).
|
|
It plays most MPEG/\:VOB, AVI, ASF/\:WMA/\:WMV, RM, QT/\:MOV/\:MP4, Ogg/\:OGM,
|
|
MKV, VIVO, FLI, NuppelVideo, yuv4mpeg, FILM and RoQ files, supported by many
|
|
native and binary codecs.
|
|
You can watch Video CD, SVCD, DVD, 3ivx, DivX 3/4/5 and even WMV movies,
|
|
too.
|
|
.PP
|
|
MPlayer supports a wide range of video and audio output drivers.
|
|
It works with X11, Xv, DGA, OpenGL, SVGAlib, fbdev, AAlib, libcaca, DirectFB,
|
|
Quartz, Mac OS X CoreVideo, but you can also use GGI, SDL (and all their drivers),
|
|
VESA (on every VESA-compatible card, even without X11), some low-level
|
|
card-specific drivers (for Matrox, 3dfx and ATI) and some hardware MPEG decoder
|
|
boards, such as the Siemens DVB, Hauppauge PVR (IVTV), DXR2 and DXR3/\:Hollywood+.
|
|
Most of them support software or hardware scaling, so you can enjoy movies in
|
|
fullscreen mode.
|
|
.PP
|
|
MPlayer has an onscreen display (OSD) for status information, nice big
|
|
antialiased shaded subtitles and visual feedback for keyboard controls.
|
|
European/\:ISO8859-1,2 (Hungarian, English, Czech, etc), Cyrillic and Korean
|
|
fonts are supported along with 12 subtitle formats (MicroDVD, SubRip, OGM,
|
|
SubViewer, Sami, VPlayer, RT, SSA, AQTitle, JACOsub, PJS and our own: MPsub) and
|
|
DVD subtitles (SPU streams, VOBsub and Closed Captions).
|
|
.PP
|
|
.B mencoder
|
|
(MPlayer's Movie Encoder) is a simple movie encoder, designed to encode
|
|
MPlayer-playable movies (see above) to other MPlayer-playable formats (see
|
|
below).
|
|
It encodes to MPEG-4 (DivX/Xvid), one of the libavcodec codecs and
|
|
PCM/\:MP3/\:VBRMP3 audio in 1, 2 or 3 passes.
|
|
Furthermore it has stream copying abilities, a powerful filter system (crop,
|
|
expand, flip, postprocess, rotate, scale, noise, RGB/\:YUV conversion) and
|
|
more.
|
|
.PP
|
|
.B gmplayer
|
|
is MPlayer with a graphical user interface.
|
|
It has the same options as MPlayer.
|

MPlayer has a fully configurable, command-driven control layer
|
|
which allows you to control MPlayer using keyboard, mouse, joystick
|
|
or remote control (with LIRC).

.SH "USAGE"
|
|
Every 'flag' option has a 'noflag' counterpart, e.g.\& the opposite of the
|
|
\-fs option is \-nofs.
|
|
.PP
|
|
If an option is marked as (XXX only), it will only work in combination with
|
|
the XXX option or if XXX is compiled in.
|
|
.PP
|
|
.I NOTE:
|
|
The suboption parser (used for example for \-ao pcm suboptions) supports
|
|
a special kind of string-escaping intended for use with external GUIs.
|
|
.br
|
|
It has the following format:
|
|
.br
|
|
%n%string_of_length_n
|
|
.br
|
|
.I EXAMPLES:
|
|
.br
|
|
mplayer \-ao pcm:file=%10%C:test.wav test.avi
|
|
.br
|
|
Or in a script:
|
|
.br
|
|
mplayer \-ao pcm:file=%`expr length "$NAME"`%"$NAME" test.avi

|
|
.
|
|
.SH "CONFIGURATION FILES"
|
|
You can put all of the options in configuration files which will be read
|
|
every time MPlayer/MEncoder is run.
|
|
The system-wide configuration file 'mplayer.conf' is in your configuration
|
|
directory (e.g.\& /etc/\:mplayer or /usr/\:local/\:etc/\:mplayer), the user
|
|
specific one is '~/\:.mplayer/\:config'.
|
|
The configuration file for MEncoder is 'mencoder.conf' in your configuration
|
|
directory (e.g.\& /etc/\:mplayer or /usr/\:local/\:etc/\:mplayer), the
|
|
user specific one is '~/\:.mplayer/\:mencoder.conf.
|
|
User specific options override system-wide options and options given on the
|
|
command line override either.
|
|
The syntax of the configuration files is 'option=<value>', everything after
|
|
a '#' is considered a comment.
|
|
Options that work without values can be enabled by setting them to 'yes'
|
|
or '1' or 'true' and disabled by setting them to 'no' or '0' or 'false'.
|
|
Even suboptions can be specified in this way.
|
|
.PP
|
|
You can also write file-specific configuration files.
|
|
If you wish to have a configuration file for a file called 'movie.avi', create a file
|
|
named 'movie.avi.conf' with the file-specific options in it and put it in
|
|
~/.mplayer/.
|
|
You can also put the configuration file in the same directory as the file to
|
|
be played, as long as you give the \-use-filedir-conf option (either on the
|
|
command line or in your global config file).

.B \-autoq <quality> (use with \-vf [s]pp)
|
|
Dynamically changes the level of postprocessing depending on the available spare
|
|
CPU time.
|
|
The number you specify will be the maximum level used.
|
|
Usually you can use some big number.
|

You have to use \-vf [s]pp without parameters in order for this to work.

.
|
|
.TP
|
|
.B \-autosync <factor>
|
|
Gradually adjusts the A/V sync based on audio delay measurements.
|
|
Specifying \-autosync 0, the default, will cause frame timing to be based
|
|
entirely on audio delay measurements.
|
|
Specifying \-autosync 1 will do the same, but will subtly change the A/V
|
|
correction algorithm.
|
|
An uneven video framerate in a movie which plays fine with \-nosound can
|
|
often be helped by setting this to an integer value greater than 1.
|
|
The higher the value, the closer the timing will be to \-nosound.
|
|
Try \-autosync 30 to smooth out problems with sound drivers which do
|
|
not implement a perfect audio delay measurement.
|
|
With this value, if large A/V sync offsets occur, they will only take about
|
|
1 or 2 seconds to settle out.
|
|
This delay in reaction time to sudden A/V offsets should be the only
|
|
side-effect of turning this option on, for all sound drivers.
|
|
.
|
|
.TP
|
|
.B \-benchmark

Prints some statistics on CPU usage and dropped frames at the end of playback.

Use in combination with \-nosound and \-vo null for benchmarking only the
|
|
video codec.
|
|
.br
|
|
.I NOTE:
|
|
With this option MPlayer will also ignore frame duration when playing

only video (you can think of that as infinite fps).

Changes the colorkey to an RGB value of your choice.

.B \-correct-pts (experimental)
|
|
Switches MPlayer to an experimental mode where timestamps for video frames
|
|
are calculated differently and video filters which add new frames or
|
|
modify timestamps of existing ones are supported.
|
|
The more accurate timestamps can be visible for example when playing
|
|
subtitles timed to scene changes with the \-ass option.
|
|
Without \-correct-pts the subtitle timing will typically be off by some frames.
|
|
This option does not work correctly with some demuxers and codecs.

|
|
.TP
|
|
.B \-edlout <filename>
|
|
Creates a new file and writes edit decision list (EDL) records to it.
|
|
During playback, the user hits 'i' to mark the start or end of a skip block.
|
|
This provides a starting point from which the user can fine-tune EDL entries
|
|
later.

.B \-fixed-vo
|
|
Enforces a fixed video system for multiple files (one (un)initialization for

|
all files).
|
|
Therefore only one window will be opened for all files.
|
|
Currently the following drivers are fixed-vo compliant: gl, gl2, mga, svga, x11,
|

xmga, xv, xvidix and dfbmga.

Show file parameters in an easily parseable format.
|
|
Also prints more detailed information about subtitle and audio
|
|
track languages and IDs.
|
|
In some cases you can get more information by using \-msglevel identify=6.
|
|
For example, for a DVD it will list the time length of each title, as well
|
|
as a disk ID.

A FIFO of size n can buffer (n-1) events.
|

If it is too small some events may be lost
|
|
(leading to "stuck mouse buttons" and similar effects).

Request the number of playback channels (default: 2).

MPlayer asks the decoder to decode the audio into as many channels as

This is usually only important when playing videos with AC3 audio (like DVDs).

audio into the requested number of channels.

channels are decoded, use the channels filter.

OpenGL video output driver, simple version.

Video size must be smaller than

Intended to work even with the most basic OpenGL implementations,

The code performs very few checks, so if a feature does not work, this

.B volume[=v[:sc]]
|
|
Implements software volume control.
|
|
Use this filter with caution since it can reduce the signal
|
|
to noise ratio of the sound.
|
|
In most cases it is best to set the level for the PCM sound to max,
|
|
leave this filter out and control the output level to your
|
|
speakers with the master volume control of the mixer.
|
|
In case your sound card has a digital PCM mixer instead of an analog
|
|
one, and you hear distortion, use the MASTER mixer instead.
|
|
If there is an external amplifier connected to the computer (this
|
|
is almost always the case), the noise level can be minimized by
|
|
adjusting the master level and the volume knob on the amplifier
|
|
until the hissing noise in the background is gone.
|
|
.br
|

This filter has a second feature: It measures the overall maximum

sound level and prints out that level when MPlayer exits.

MEncoder such that the maximum dynamic range is utilized.

Attempts to reverse the 'telecine' process to recover a clean,

This was the first and most primitive inverse telecine filter to be

added to MPlayer/\:MEncoder.
|
|
It works by latching onto the telecine 3:2 pattern and following it as
|
|
long as possible.

This makes it suitable for perfectly-telecined material, even in the

presence of a fair degree of noise, but it will fail in the presence

of complex post-telecine edits.

.B ivtc[=1]

|
Experimental 'stateless' inverse telecine filter.
|
|
Rather than trying to lock on to a pattern like the detc filter does,
|
|
ivtc makes its decisions independently for each frame.
|
|
This will give much better results for material that has undergone
|
|
heavy editing after telecine was applied, but as a result it is not as
|
|
forgiving of noisy input, for example TV capture.
|
|
The optional parameter (ivtc=1) corresponds to the dr=1 option for the
|
|
detc filter, and should be used with MEncoder but not with MPlayer.
|
|
As with detc, you must specify the correct output framerate (\-ofps
|
|
24000/1001) when using MEncoder.
|
|
Further development on ivtc has stopped, as the pullup and filmdint
|

filters appear to be much more accurate.

capable of handling mixed hard-telecine, 24000/1001 fps progressive, and 30000/1001
|

fps progressive content.
|
|
The pullup filter is designed to be much more robust than detc or
|
|
ivtc, by taking advantage of future context in making its decisions.
|
|
Like ivtc, pullup is stateless in the sense that it does not lock onto
|
|
a pattern to follow, but it instead looks forward to the following
|
|
fields in order to identify matches and rebuild progressive frames.
|

It is still under development, but believed to be quite accurate.

Setting this option to 1 will reduce the chances of

pullup generating an occasional mismatched frame, but it may also

cause an excessive number of frames to be dropped during high motion
|
|
sequences.
|
|
Conversely, setting it to -1 will make pullup match fields more
|
|
easily.
|
|
This may help processing of video where there is slight blurring
|
|
between the fields, but may also cause there to be interlaced frames
|

in the output.

.IPs "mp (metric plane)"

This option may be set to 1 or 2 to use a chroma

This may improve accuracy on very clean source material, but more

likely will decrease accuracy, especially if there is chroma noise
|

(rainbow effect) or any grayscale video.

The main purpose of setting mp to a chroma plane is to reduce CPU load

Inverse telecine filter, similar to the pullup filter above.

It is designed to handle any pulldown pattern, including mixed soft and
|
|
hard telecine and limited support for movies that are slowed down or sped
|
|
up from their original framerate for TV.
|
|
Only the luma plane is used to find the frame breaks.
|
|
If a field has no match, it is deinterlaced with simple linear
|
|
approximation.
|
|
If the source is MPEG-2, this must be the first filter to allow
|
|
access to the field-flags set by the MPEG-2 decoder.
|
|
Depending on the source MPEG, you may be fine ignoring this advice, as
|
|
long as you do not see lots of "Bottom-first field" warnings.
|
|
With no options it does normal inverse telecine, and should be used
|
|
together with mencoder \-fps 30000/1001 \-ofps 24000/1001.
|
|
When this filter is used with mplayer, it will result in an uneven
|
|
framerate during playback, but it is still generally better than using
|
|
pp=lb or no deinterlacing at all.
|

Multiple options can be specified separated by /.
|

.RSs

.IPs crop=<w>:<h>:<x>:<y>
|
|
Just like the crop filter, but faster, and works on mixed hard and soft
|
|
telecined content as well as when y is not a multiple of 4.
|
|
If x or y would require cropping fractional pixels from the chroma
|
|
planes, the crop area is extended.
|
|
This usually means that x and y must be even.
|
|
.IPs io=<ifps>:<ofps>
|
|
For each ifps input frames the filter will output ofps frames.
|
|
The ratio of ifps/\:ofps should match the \-fps/\-ofps ratio.
|
|
This could be used to filter movies that are broadcast on TV at a frame
|
|
rate different from their original framerate.
|
|
.IPs luma_only=<n>
|
|
If n is nonzero, the chroma plane is copied unchanged.
|
|
This is useful for YV12 sampled TV, which discards one of the chroma
|
|
fields.
|
|
.IPs mmx2=<n>
|
|
On x86, if n=1, use MMX2 optimized functions, if n=2, use 3DNow!
|
|
optimized functions, otherwise, use plain C.
|
|
If this option is not specified, MMX2 and 3DNow! are auto-detected, use
|
|
this option to override auto-detection.
|
|
.IPs fast=<n>
|
|
The larger n will speed up the filter at the expense of accuracy.
|
|
The default value is n=3.
|
|
If n is odd, a frame immediately following a frame marked with the
|
|
REPEAT_FIRST_FIELD MPEG flag is assumed to be progressive, thus filter
|
|
will not spend any time on soft-telecined MPEG-2 content.
|
|
This is the only effect of this flag if MMX2 or 3DNow! is available.
|
|
Without MMX2 and 3DNow, if n=0 or 1, the same calculations will be used
|
|
as with n=2 or 3.
|
|
If n=2 or 3, the number of luma levels used to find the frame breaks is
|
|
reduced from 256 to 128, which results in a faster filter without losing
|
|
much accuracy.
|
|
If n=4 or 5, a faster, but much less accurate metric will be used to
|
|
find the frame breaks, which is more likely to misdetect high vertical
|
|
detail as interlaced content.

This filter works only correct with MEncoder and acts on the MPEG-2 flags

Inverse telecine for deinterlaced video.
|
|
If 3:2-pulldown telecined video has lost one of the fields or is deinterlaced
|
|
using a method that keeps one field and interpolates the other, the result is
|
|
a juddering video that has every fourth frame duplicated.
|
|
This filter is intended to find and drop those duplicates and restore the
|
|
original film framerate.
|
|
When using this filter, you must specify \-ofps that is 4/5 of
|
|
the fps of the input file and place the softskip later in the
|
|
filter chain to make sure that divtc sees all the frames.
|
|
Two different modes are available:
|
|
One pass mode is the default and is straightforward to use,
|
|
but has the disadvantage that any changes in the telecine
|
|
phase (lost frames or bad edits) cause momentary judder
|
|
until the filter can resync again.
|
|
Two pass mode avoids this by analyzing the whole video
|
|
beforehand so it will have forward knowledge about the
|
|
phase changes and can resync at the exact spot.
|
|
These passes do
|
|
.B not
|
|
correspond to pass one and two of the encoding process.
|
|
You must run an extra pass using divtc pass one before the
|
|
actual encoding throwing the resulting video away.
|
|
Use \-nosound \-ovc raw \-o /dev/null to avoid
|
|
wasting CPU power for this pass.
|
|
You may add something like crop=2:2:0:0 after divtc
|
|
to speed things up even more.
|
|
Then use divtc pass two for the actual encoding.
|
|
If you use multiple encoder passes, use divtc
|
|
pass two for all of them.
|
|
The options are:
|
|
.RSs
|
|
.IPs pass=1|2

|
.IPs file=<filename>

Set the two pass log filename (default: "framediff.log").
|
|
.IPs threshold=<value>
|
|
Set the minimum strength the telecine pattern must have for the filter to
|
|
believe in it (default: 0.5).
|
|
This is used to avoid recognizing false pattern from the parts of the video
|
|
that are very dark or very still.
|
|
.IPs window=<numframes>
|
|
Set the number of past frames to look at when searching for pattern
|
|
(default: 30).
|
|
Longer window improves the reliability of the pattern search, but shorter
|
|
window improves the reaction time to the changes in the telecine phase.
|
|
This only affects the one pass mode.
|
|
The two pass mode currently uses fixed window that extends to both future
|
|
and past.
|
|
.IPs phase=0|1|2|3|4
|
|
Sets the initial telecine phase for one pass mode (default: 0).
|
|
The two pass mode can see the future, so it is able to use the correct
|
|
phase from the beginning, but one pass mode can only guess.
|
|
It catches the correct phase when it finds it, but this option can be used
|
|
to fix the possible juddering at the beginning.
|
|
The first pass of the two pass mode also uses this, so if you save the output
|
|
from the first pass, you get constant phase result.
|
|
.IPs deghost=<value>
|
|
Set the deghosting threshold (0\-255 for one pass mode, -255\-255 for two pass
|
|
mode, default 0).
|
|
If nonzero, deghosting mode is used.
|
|
This is for video that has been deinterlaced by blending the fields
|
|
together instead of dropping one of the fields.
|
|
Deghosting amplifies any compression artifacts in the blended frames, so the
|
|
parameter value is used as a threshold to exclude those pixels from
|
|
deghosting that differ from the previous frame less than specified value.
|
|
If two pass mode is used, then negative value can be used to make the
|
|
filter analyze the whole video in the beginning of pass-2 to determine
|
|
whether it needs deghosting or not and then select either zero or the
|
|
absolute value of the parameter.
|
|
Specify this option for pass-2, it makes no difference on pass-1.

Minimum frame-level Lagrange multiplier for ratecontrol (default: 2.0).

Lavc will rarely use quantizers below the value of lmin.

Lowering lmin will make lavc more likely to choose lower quantizers for

some frames, but not lower than the value of vqmin.

Likewise, raising lmin will make lavc less likely to choose low
|
|
quantizers, even if vqmin would have allowed them.

You probably want to set lmin approximately equal to vqmin.

When adaptive quantization is in use, changing lmin/lmax may have less

of an effect; see mblmin/mblmax.

|

maximum interval between keyframes in frames (default: 250 or one

keyframe every ten seconds in a 25fps movie.
|
|
This is the recommended default for MPEG-4).
|
|
Most codecs require regular keyframes in order to limit the accumulation of mismatch error.
|
|
Keyframes are also needed for seeking, as seeking is only possible to a keyframe - but
|
|
keyframes need more space than other frames, so larger numbers here mean
|
|
slightly smaller files but less precise seeking.
|
|
0 is equivalent to 1, which makes every frame a keyframe.
|
|
Values >300 are not recommended as the quality might be bad depending upon
|
|
decoder, encoder and luck.

It is a common for MPEG-1/2 to use values <=30.

.B sc_threshold=<-1000000000\-1000000000>
|
|
Threshold for scene change detection.
|
|
A keyframe is inserted by libavcodec when it detects a scene change.
|
|
You can specify the sensitivity of the detection with this option.
|
|
-1000000000 means there is a scene change detected at every frame,
|
|
1000000000 means no scene changes are detected (default: 0).

.B sc_factor=<any positive integer>
|
|
Causes frames with higher quantizers to be more likely to trigger a
|
|
scene change detection and make libavcodec use an I-frame (default: 1).
|
|
1\-16 is a sane range.
|
|
Values between 2 and 6 may yield increasing PSNR (up to approximately
|
|
0.04 dB) and better placement of I-frames in high-motion scenes.
|
|
Higher values than 6 may give very slightly better PSNR (approximately

0.01 dB more than sc_factor=6), but noticably worse visual quality.

.B b_sensitivity=<any integer greater than 0>
|
|
Adjusts how sensitively vb_strategy=1 detects motion and avoids using
|
|
B-frames (default: 40).
|
|
Lower sensitivities will result in more B-frames.
|
|
Using more B-frames usually improves PSNR, but too many B-frames can
|
|
hurt quality in high-motion scenes.
|
|
Unless there is an extremely high amount of motion, b_sensitivity can
|
|
safely be lowered below the default; 10 is a reasonable value in most

cases.

|
|
.B brd_scale=<0\-10>
|
|
Downscales frames for dynamic B-frame decision (default: 0).
|
|
Each time brd_scale is increased by one, the frame dimensions are
|
|
divided by two, which improves speed by a factor of four.
|
|
Both dimensions of the fully downscaled frame must be even numbers, so
|
|
brd_scale=1 requires the original dimensions to be multiples of four,
|
|
brd_scale=2 requires multiples of eight, etc.
|
|
In other words, the dimensions of the original frame must both be
|
|
divisible by 2^(brd_scale+1) with no remainder.

|
|
Here is how it works, and how to use it:
|
|
.br
|
|
The first pass (vpass=1) writes the statistics file.
|
|
You might want to deactivate some CPU-hungry options, like "turbo"
|
|
mode does.
|
|
.br
|
|
In two pass mode, the second pass (vpass=2) reads the statistics file and
|
|
bases ratecontrol decisions on it.
|
|
.br
|
|
In N-pass mode, the second pass (vpass=3, that is not a typo)
|
|
does both: It first reads the statistics, then overwrites them.
|
|
You might want to backup divx2pass.log before doing this if there is
|
|
any possibility that you will have to cancel MEncoder.
|
|
You can use all encoding options, except very CPU-hungry options like "qns".
|
|
.br
|
|
You can run this same pass over and over to refine the encode.
|
|
Each subsequent pass will use the statistics from the previous pass to improve.
|
|
The final pass can include any CPU-hungry encoding options.
|
|
.br
|
|
If you want a 2 pass encode, use first vpass=1, and then vpass=2.
|
|
.br
|
|
If you want a 3 or more pass encode, use vpass=1 for the first pass
|
|
and then vpass=3 and then vpass=3 again and again until you are
|
|
satisfied with the encode.

Temporal complexity masking (default: 0.0 (disabled)).
|
|
Imagine a scene with a bird flying across the whole scene; tcplx_mask

will raise the quantizers of the bird's macroblocks (thus decreasing their

|
quality), as the human eye usually does not have time to see all the bird's

details.
|
|
Be warned that if the masked object stops (e.g.\& the bird lands) it is
|
|
likely to look horrible for a short period of time, until the encoder
|
|
figures out that the object is not moving and needs refined blocks.
|

The saved bits will be spent on other parts of the video, which may increase

subjective quality, provided that tcplx_mask is carefully chosen.

Quantizer noise shaping.
|
|
Rather than choosing quantization to most closely match the source video
|
|
in the PSNR sense, it chooses quantization such that noise (usually ringing)
|
|
will be masked by similar-frequency content in the image.
|
|
Larger values are slower but may not result in better quality.
|
|
This can and should be used together with trellis quantization, in which case
|
|
the trellis quantization (optimal for constant weight) will be used as
|
|
startpoint for the iterative search.

Here is how it works, and how to use it:

.br

The first pass (pass=1) collects statistics on the video and writes them

to a file.

|
You might want to deactivate some CPU-hungry options, apart from the ones
|
|
that are on by default.

In two pass mode, the second pass (pass=2) reads the statistics file and

bases ratecontrol decisions on it.

|
.br
|
|
In three pass mode, the second pass (pass=3, that is not a typo)

does both: It first reads the statistics, then overwrites them.

You can use all encoding options, except very CPU-hungry options.

The third pass (pass=3) is the same as the second pass, except that it has
|
|
the second pass' statistics to work from.

|
You can use all encoding options, including CPU-hungry ones.
|
|
.br
|
|
The first pass may use either average bitrate or constant quantizer.

ABR is recommended, since it does not require guessing a quantizer.

Subsequent passes are ABR, and must specify bitrate.

.B keyint=<value>

Sets maximum interval between IDR-frames (default: 250).

Larger values save bits, thus improve quality, at the cost of seeking

precision.

Unlike MPEG-1/2/4, H.264 does not suffer from DCT drift with large

values of keyint.

Sets minimum interval between IDR-frames (default: 25).

If scenecuts appear within this interval, they are still encoded as
|
|
I-frames, but do not start a new GOP.
|
|
In H.264, I-frames do not necessarily bound a closed GOP because it is
|
|
allowable for a P-frame to be predicted from more frames than just the one
|
|
frame before it (also see frameref).
|
|
Therefore, I-frames are not necessarily seekable.

IDR-frames restrict subsequent P-frames from referring to any frame

prior to the IDR-frame.

.B scenecut=<-1\-100>
|

Controls how aggressively to insert extra I-frames (default: 40).
|

With small values of scenecut, the codec often has to force an I-frame
|
|
when it would exceed keyint.
|
|
Good values of scenecut may find a better location for the I-frame.
|
|
Large values use more I-frames than necessary, thus wasting bits.
|
|
-1 disables scene-cut detection, so I-frames are inserted only once
|
|
every other keyint frames, even if a scene-cut occurs earlier.
|
|
This is not recommended and wastes bitrate as scenecuts encoded as P-frames
|
|
are just as big as I-frames, but do not reset the "keyint counter".

Number of previous frames used as predictors in B- and P-frames (default: 1).

This is effective in anime, but in live-action material the improvements

usually drop off very rapidly above 6 or so reference frames.

.B (no)b_pyramid
|
|
Allows B-frames to be used as references for predicting other frames.
|
|
For example, consider 3 consecutive B-frames: I0 B1 B2 B3 P4.
|
|
Without this option, B-frames follow the same pattern as MPEG-[124].
|
|
So they are coded in the order I0 P4 B1 B2 B3, and all the B-frames
|
|
are predicted from I0 and P4.
|
|
With this option, they are coded as I0 P4 B2 B1 B3.
|
|
B2 is the same as above, but B1 is predicted from I0 and B2, and
|
|
B3 is predicted from B2 and P4.
|
|
This usually results in slightly improved compression, at almost no
|
|
speed cost.
|
|
However, this is an experimental option: it is not fully tuned and

may not always help.

The first parameter is AlphaC0 (default: 0).

This adjusts thresholds for the H.264 in-loop deblocking filter.
|
|
First, this parameter adjusts the maximum amount of change that the filter is
|
|
allowed to cause on any one pixel.
|
|
Secondly, this parameter affects the threshold for difference across the

|
edge being filtered.
|
|
A positive value reduces blocking artifacts more, but will also smear details.
|
|
.br
|
|
The second parameter is Beta (default: 0).
|

This affects the detail threshold.
|
|
Very detailed blocks are not filtered, since the smoothing caused by the
|
|
filter would be more noticeable than the original blocking.
|
|
.br
|
|
The default behavior of the filter almost always achieves optimal quality,
|
|
so it is best to either leave it alone, or make only small adjustments.

Negative values result in fewer messages while positive

.B DVDCSS_CACHE
|
|
Specify a directory in which to store title key values.
|
|
This will speed up descrambling of DVDs which are in the cache.
|
|
The DVDCSS_CACHE directory is created if it does not exist,
|
|
and a subdirectory is created named after the DVD's title
|
|
or manufacturing date.
|
|
If DVDCSS_CACHE is not set or is empty, libdvdcss will use
|
|
the default value which is "${HOME}/.dvdcss/" under Unix and
|
|
"C:\\Documents and Settings\\$USER\\Application Data\\dvdcss\\" under Win32.
|
|
The special value "off" disables caching.

|
|
.TP
|
|
.B DVDCSS_METHOD
|
|
Sets the authentication and decryption method that
|
|
libdvdcss will use to read scrambled discs.
|
|
Can be one of title, key or disc.
|
|
.PD 0
|
|
.RSs
|
|
.IPs "key\ \ "
|
|
is the default method.
|
|
libdvdcss will use a set of calculated player keys to try and get the disc key.
|
|
This can fail if the drive does not recognize any of the player keys.
|
|
.IPs "disc\ "
|
|
is a fallback method when key has failed.
|
|
Instead of using player keys, libdvdcss will crack the disc key using
|
|
a brute force algorithm.
|
|
This process is CPU intensive and requires 64 MB of memory to store
|
|
temporary data.
|
|
.IPs title
|
|
is the fallback when all other methods have failed.
|
|
It does not rely on a key exchange with the DVD drive, but rather uses
|
|
a crypto attack to guess the title key.
|
|
On rare cases this may fail because there is not enough encrypted data
|
|
on the disc to perform a statistical attack, but in the other hand it
|
|
is the only way to decrypt a DVD stored on a hard disc, or a DVD with
|
|
the wrong region on an RPC2 drive.

.B DVDCSS_RAW_DEVICE
|
|
Specify the raw device to use.
|
|
Exact usage will depend on your operating system, the Linux
|
|
utility to set up raw devices is raw(8) for instance.
|
|
Please note that on most operating systems, using a raw device
|
|
requires highly aligned buffers: Linux requires a 2048 bytes

alignment (which is the size of a DVD sector).
