Remove the options --utf8 and --unicode which had no effect any more
(what they once did should be doable with --subcp). The only use of
corresponding variables left in code was subreader.c code using
sub_utf8 as a flag indicating whether iconv conversion was active.
Change the code to test the existence of iconv context instead.

When the cache fill status goes below a certain threshold, automatically
pause the player. When the cache is filled again, unpause again.
This is intended to help with streaming from http. It's better to pause
a while, rather than exposing extremely crappy behavior when packet
reads during decoding block the entire player.
In theory, we should try to increase the cache if underruns happen too
often. Unfortunately, changing the cache implementation would be very
hard, because it's insane code (forks, uses shared memory and "volatile"
etc.). So for now, this just reduces the frequency of the stuttering if
the network is absolutely too slow to play the stream in realtime.
This commit is separate from the previous one to separate our own
changes from changes merged from mplayer2 (as far as that was possible).
Make it easier for stream implementations to request being cached. Set
a default cache size in stream.c, and remove them from various stream
implementations. Only MS streaming support sets a meaningful cache size.
Make querying cache size saner. This reduces the amount of #ifdefs
needed.
Code enabling the cache by default for network streams did that by
modifying the value of the "cache" option. This wasn't sane, as
multiple streams may be created and all share the same options. Change
the code to not modify options but store data in the stream instance
instead.

Merged from mplayer2 commit e26070. Note that this doesn't solve any
actual bug, as the playlist crashing bug has been fixed before.
Since the global cache size option value is not overwritten anymore, the
option doesn't need to be restored on end of playback (M_OPT_LOCAL).
Based on a patch by qyot27. Add export LC_ALL=C on top of version.sh to
make the output locale independent.
Note that the build time will not be updated on every "make" invocation,
but only when the git revision is updated. This is a good thing, as
repeated make invocations should not rebuild the binary. (This would
break "sudo make install" too.)
libavdevice supports various "special" video and audio inputs, such
as screen-capture or libavfilter filter graphs.
libavdevice inputs are implemented as demuxers. They don't use the
custom stream callbacks (in AVFormatContext.pb). Instead, input
parameters are passed as filename. This means the mpv stream layer has
to be disabled. Do this by adding the pseudo stream handler avdevice://,
whose only purpose is passing the filename to demux_lavf, without
actually doing anything.
Change the logic how the filename is passed to libavformat. Remove
handling of the filename from demux_open_lavf() and move it to
lavf_check_file(). (This also fixes a possible bug when skipping the
"lavf://" prefix.)
libavdevice now can be invoked by specifying demuxer and args as in:
mpv avdevice://demuxer:args
The args are passed as filename to libavformat. When using libavdevice
demuxers, their actual meaning is highly implementation specific. They
don't refer to actual filenames.
Note:
libavdevice is disabled by default. There is one problem: libavdevice
pulls in libavfilter, which in turn causes symbol clashes with mpv
internals. The problem is that libavfilter includes a mplayer filter
bridge, which is used to interface with a set of nearly unmodified
mplayer filters copied into libavfilter. This filter bridge uses the
same symbol names as mplayer/mpv's filter chain, which results in symbol
clashes at link-time.
This can be prevented by building ffmpeg with --disable-filter=mp, but
unfortunately this is not the default.
This means linking to libavdevice (which in turn forces linking with
libavfilter by default) must be disabled. We try doing this by compiling
a test file that defines one of the clashing symbols (vf_mpi_clear).
To enable libavdevice input, ffmpeg should be built with the options:
--disable-filter=mp
and mpv with:
--enable-libavdevice
Originally, I tried to auto-detect it. But the resulting complications
in configure did't seem worth the trouble.
This is consistent with the demuxer/decoder info output mpv already has,
and is also generally useful to know, especially if using
--ao=codec1,codec2,... syntax.
This caused e.g. "--alang=" (without anything following) to be printed
in the terminal output when the file specified no language for the
track. Introduced by commit 9085b8.
MPlayer/mplayer2 still show DVD subtitles in gray. Depending on who you
ask, this can be considered a bug or a feature. Include rendering in
gray as explicit feature, so the user can decide what is better.
This affects all indexed sub bitmaps entering the OSD rendering path.
Currently, this means all image subs are affected by this option, but
nothing else.
Apparently the -spugauss option was popular. The code originally
implementing this is gone (scaler stuff in spudec.c). Reimplement it
using libswscale to scale and blur image subtitles if the --sub-gauss
option is set.
The code does some rather lazy padding to allow the blur to spread
pixels past the original image bounding box. (This problem exists with
normal bilinear scaling too, but is barely noticable.)
Technically, this doesn't just blur subtitles, but anything RGBA (or
indexed) that enters the OSD rendering path. But only image subtitles
produce these OSD formats currently, so no explicit check is done to
prevent blurring in other cases.
Until now, screenshots with the video filter didn't add subs (unclear
whether that was an oversight or feature). Fix this and make behavior
when taking screenshots with vf_screenshot more consistent with VO
screenshots.
The change in vf_screenshot is needed, because add_subs() checks this
flag to decide whether it's allowed to mutate the image.
This commit has another user visible side effect. When taking a
screenshot each frame (using the "each-frame" mode of the screenshot
command), a normal screenshot command will stop the each-frame mode.
mp_image has this confusing distinction between the w/h and width/height
fields. w/h are the actual width and height, while width/height have a
very special meaning inside the video filter code: it's the actually
allocated width, which is also used for stride padding.
Screenshot related code abused the w/h fields to store the aspect
corrected size. Some code confused the role of w/h and width/height.
Fix these issues. For aspect corrected size, display_w/h are used, while
width/height should never be used outside vf.c internals and related
code.
This also fixes an actual bug when taking screenshots of anamorphic
video with vf_screenshot, as well as using vo_image with such videos.
Enable printf format warnings for set_osd_[t]msg.
Remove the pointless assertion in mplayer.c (the assertion proved that
the following NULL check is probably pointless, but leave that check
anyway for robustness - it's not really clear whether it's needed).
The playback status symbol in the OSD status display on video (such as
displayed when seeking or with the show_progress input command)
sometimes kept displaying the last seek, without resetting the symbol.
(For example: disable the OSD, seek, enable the OSD, run show_progress;
but also other cases.)
The main reason for that was the code clearing the OSD bar is also
responsible for clearing the osd_function (which stores the playback
symbol). If no OSD bar was set, the osd_function was never reset.
Fix by always setting the timer for clearing the OSD bar and the
osd_function whenever the osd_function is set. Clearing the OSD bar
when it wasn't set is OK. If the OSD bar is set some time after
osd_function is set, the timer is overwritten - that's a good thing,
as it makes both disappear from the screen at exactly the same time.
Always reset osd_function to 0 and determine the playback status
explicitly from mpctx->paused when displaying the status on screen.
Do not load codecs.conf files located in $PREFIX/etc/mpv/ or ~/.mpv/.
There really is no use for this, other than possibly breaking things.
It's still possible to use --codecs-file explicitly to load an external
config file, and this option can be used in ~/.mpv/config.
While we're at it, remove the global codecs_file variable, and another
unused variable.
Only some choices have an additional integer range. For those which
do, printing the choices only would be confusing.
E.g. --cursor-autohide accepts the choices "always", "no", or an
integer value. The help text printed on option parse errors should
print the accepted integer range additional to "always" and "no".
Make more aspects of the OSD font customizable. This also affects the
font used for unstyled subtitles (such as SRT), or when using the
--no-ass option. This adds back some customizability that was lost with
commit 74e7a1 (osd: use libass for OSD rendering).
Removed options:
--ass-border-color
--ass-color
--font
--subfont
--subfont-text-scale
Added options:
--osd-color
--osd-border
--osd-back-color
--osd-shadow-color
--osd-font
--osd-font-size
--osd-border-size
--osd-margin-x
--osd-margin-y
--osd-shadow-offset
--osd-spacing
--sub-scale
The font size is now specified in pixels as it would be rendered on a
window with a height of 720 pixels. OSD and subtitles are always scaled
with the window height, so specifying or expecting an absolute font
size doesn't make sense.
Such scaled pixel units are used to specify font border etc. as well.
(Note: the font size is directly passed to libass. How the fonts are
actually rasterized is outside of our control, but in theory ASS font
sizes map to "script" pixels and then are scaled to screen size.)
The default settings should be about the same, with slight difference
due to rounding to the new scales.
The OSD and subtitle fonts are not separately configurable. It has
limited use and would double the number of newly added options, which
would be more confusing than helpful. It could be easily added later,
should the need arise.
Other small details that change:
- ASS_Style.Encoding is not set to -1 for subs anymore
(assuming subs use VSFilter direction in -no-ass mode too)
- use a different WrapStyle for OSD
- ASS forced styles are not applied to OSD
This accepts HTML-style hex colors in the form #RRGGBB. It's also
possible to provide an alpha component with #AARRGGBB. Each 2-digit
group is a hex number, which gives the color value from 0-255 (e.g.
There is existing code in subassconvert.c, which parses HTML-style
color values in SRT subs. This is not used: it's probably better if
option parsing is completely separate from code specific to certain
subtitle formats, even if a little code is duplicated.
When a video filter returned inf as PTS, the player crashed. One
reason for this was that decode_audio() was called with a negative
minlen parameter, which at some point caused it to call a memory
allocation function with a ridiculous value, triggering an out of
memory code path in talloc.c. (talloc.c has been modified to abort()
on out of memory situations.)
Fix this by sanity checking minlen in decode_audio(). (The check
against outbuf->len always succeeded, because it's an unsigned
comparison.)
Make an existing sanity check in mplayer.c more robust: check for NaN
too, which happens if the video PTS is inf.
This happened with "-vf pullup,softpulldown" (but is not triggered when
the following commit is applied).
ao_play() can fail; in that case a negative error code is returned.
This error code is returned by write_to_ao() in turn. The function
fill_audio_out_buffers(), which calls write_to_ao(), doesn't check for
any error codes, and will likely trigger the assertion following the
function call. Change write_to_ao() to return 0 on failure to hopefully
prevent crashes when AOs fail.
The language string was dynamically allocated, which completely fails
if the cache is forked (which it usually is). Change it back to a fixed
length string, like the original code had it.
Most of these are reimar fixing issues found by Coverity static
analyzer, and possibly some more cleanup commits independent from
this.
Since these commits are rather noisy, squash them all together.
Try to make code a bit clearer.

The --start and --end switch now accept a chapter number. The chapter
number is prefixed with '#', e.g. "--start=#2" jumps to chapter 2.
The chapter support might be able to replace --chapter completely, but
for now I am not sure how well this works out with e.g. DVDs and BDs,
and a separate --chapter option is useful interface-wise.
(This was supposed to be added in 51503a, but apparently the fixup
commit adding it was lost in a rebase. This might also be the reason
for the mess-up fixed in 394285.)
The option type m_option_type_rel_time was completely broken. It
interpreted everything starting with a number as percent position. This
is because sscanf() semantics are idiotic (trailing string doesn't need
to be matched), and due to my own idiocy this was overlooked when
testing. Fix by considering sscanf() evil and not using it.
(bstr_sscanf() is a straight wrapper around sscanf()).
Even if the percent code was fixed, there was another bug: it always
interpreted times as negative (starting from end for --start). Fix the
basic logic.
Enable autoprobing for demux_mf, so that image files can be directly
displayed with e.g. "mpv file.jpg --pause". (The --pause switch is
needed to prevent the window from closing immediately.)
Since demux_mf doesn't have any real file format probing and goes by
file extension only, move the demuxer down the demuxer list to ensure
it's checked last. (ffmpeg's demux_mf equivalent, "image2", probes by
file extensions too, and there doesn't seem to be anything that can
probe typical image file formats from binary data.)
Remove the --mf "w" and "h" suboptions. Don't pass the width/height to
the video stream header. Both of these are useless, because the decoder
reads the real image size at a later point from the file headers.
Remove setting the BITMAPINFOHEADER as well, as vd_lavc doesn't need
this.
Enable --correct-pts by default. This fixes displaying a single image
with vo_vdpau (as mentioned by uau).
Keep around a pointer to the sh_video stream header instead of
accessing demuxer->video->sh_video. Fixes a crash when deselecting the
video track.
Note that the format probing is incorrect when opening images from HTTP
locations. File extensions don't have to match the actual file format.
A correct implementation would require to check the MIME type, or to
probe the binary data correctly.
Make demux_lavf not error out if no video or audio track is present.
This allows opening subtitle files with the demuxer.
Improve the test whether subtitles read from demuxers must do explicit
packet reads. (I'm not sure whether always doing these reads could have
bad effects, such as reading too many audio and video packets at once,
so be conservative.)
The computation for the A/V sync value was inside print_status(). Move
it into its own function; this makes things simpler and gets rid of some
minor dead code.
The --keep-open option causes mpv not to close the current file.
Instead, it will pause, and allow the user to seek around. When
seeking beyond the end of the file, mpv does a precise seek back to
the previous last known position that produced video output.
In some corner cases, mpv might not be able to produce video output at
all, despite having created a VO. (Possibly when only 1 frame could be
decoded, but the video filter chain queues frames. Then a VO would be
created, without sending an actual video frame to the VO.) In these
cases, the VO window will not redraw, not even OSD.
Based on a patch by coax [1].

sub_remove remove an external subtitle track, for whatever this may be
needed.
sub_reload removes and re-adds an external subtitle track.
Also rename sub_load to sub_add, because that seems to be more in line
with sub_remove.
"--autosub-match" is close to "--autosub", and reflects what this
option does slightly better. Replace the magic number option values
with choices:
--sub-fuzziness=0 becomes --autosub-match=exact
--sub-fuzziness=1 becomes --autosub-match=fuzzy
--sub-fuzziness=2 becomes --autosub-match=all
Rename the -ss option to -start, and -endpos to -length. Add a -end
option. The -end option always specifies an absolute end time, as
opposed to -endpos/-length.
All these options (--start, --end, --length) now accept relative times.
Percent positions (e.g. "--start=30%") are interpreted as fractions of
the file duration. Negative times (e.g. "--start=-1:00) are interpreted
relative to the end of the file. Chapters (e.g. "--start=#3") yield the
chapter's time position.
The chapter support might be able to replace --chapter completely, but
for now I am not sure how well this works out with e.g. DVDs and BDs,
and a separate --chapter option is useful interface-wise.
Using --no-msgcolor, error messages that happened before "really"
parsing the command line were still printed in color. Add the
CONF_PRE_PARSE flag to make this option take effect as early as
possible.
The -zoom option enabled scaling with vo_x11. Remove the -zoom option,
and make its behavior default. Since vo_x11 has to use libswscale for
colorspace conversion anyway, which doesn't do actual extra scaling when
vo_x11 is run in windowed mode, there should be no speed difference with
this change.
The code removed from vf_scale attempted to scale the video to d_width/
d_height, which matters for anamorphic video and the --xy option only.
vo_x11 can handle these natively. The only case for which the removed
vf_scale code could matter is encoding with vo_lavc, but since that
didn't set VOFLAG_SWSCALE, nothing actually changes.
It's silly to print a warning if an optional config file is missing.
Don't print anything at the default message level if an input config
is not found.
Unfortunately, the behavior is the same for explicitly passed input
config files (with --input=conf=file.conf).
Using --loop=inf on an unseekable file would put mpv (and all other
mplayers as well) into an endless loop, trying to seek to the start of
the file on each playback loop iteration. When the seek fails, playback
simply remains in the at-end-of-file state, and tries to issue a new
seek command for looping.
Fix by checking if the seek command fails, and abort looping in this
case. For that, queue_seek() is replaced with seek(). Due to the
circumstances, these two calls happen to be equal in this case: the
seek is absolute (i.e. no seek coalescing done), and the execution of
queued seeks is right after the loop code anyway.
In this example, only f1.mkv was looped: mpv f1.mkv f2.mkv --loop=2
This is because the playloop actually changes the global option value,
assuming it would be reset when going to the next file. When mpv was
changed to not reset options between files, this assumption was broken.
Normally, we always want to enable encoding, as it uses stock ffmpeg
APIs and has no other dependencies or disadvantages.
However, supporting older releases of ffmpeg and Libav (which equal to
outdated git snapshots fix security and crash fixes applied) force us
to disable some advanced ffmpeg API usage, which includes encoding.
This removes the rather complicated configure and Makefile parts
related to auto-detecting available languages for manpages and locales.
We don't have non-English manpages or any locales, so this is
pointless. It didn't even work: configure --language=all created an
invalid config.mak that would cause "make install" to fail.
Remove installation of locales. There are no translations at all which
could be installed. Should there ever be someone who is interested in
adding translations, this can be added back in a simpler way.
Rename the --enable-translation configure option to --enable-gettext.
This is what this option really does: enable gettext() use. This may
be interesting for people who want to experiment with localizing mpv,
but is entirely useless for normal use.
Remove detection of the binary codecs directory in configure.
Put MP_EXPAND_ARGS() in compiler.h, even though it's not compiler
dependent. Both mp_talloc.h and mp_common.h need it, while mp_common.h
includes mp_talloc.h. This is the least annoying solution.
Finish renaming directories and moving files. Adjust all include
statements to make the previous commit compile.
The two commits are separate, because git is bad at tracking renames
and content changes at the same time.
Also take this as an opportunity to remove the separation between
"common" and "mplayer" sources in the Makefile. ("common" used to be
shared between mplayer and mencoder.)
Tis drops the silly lib prefixes, and attempts to organize the tree in
a more logical way. Make the top-level directory less cluttered as
well.
Renames the following directories:
libaf -> audio/filter
libao2 -> audio/out
libvo -> video/out
libmpdemux -> demux
Split libmpcodecs:
vf* -> video/filter
vd*, dec_video.* -> video/decode
mp_image*, img_format*, ... -> video/
ad*, dec_audio.* -> audio/decode
libaf/format.* is moved to audio/ - this is similar to how mp_image.*
is located in video/.
Move most top-level .c/.h files to core. (talloc.c/.h is left on top-
level, because it's external.) Park some of the more annoying files
in compat/. Some of these are relicts from the time mplayer used
ffmpeg internals.
sub/ is not split, because it's too much of a mess (subtitle code is
mixed with OSD display and rendering).
Maybe the organization of core is not ideal: it mixes playback core
(like mplayer.c) and utility helpers (like bstr.c/h). Should the need
arise, the playback core will be moved somewhere else, while core
contains all helper and common code.
