wm4 cf8fa2bdd4 options: slightly improve help output for choice and flag options 2015-02-02 18:07:37 +01:00
wm4 9b8d3acc8b options: list correct default value for --screenshot-template
Make the default value part of the option metadata, instead of doing
this in the screenshot code. Makes more sense with --list-options and
the command.c option metadata properties.

wm4 96f7c96da0 msg: add --log-file option
This allows getting the log at all with --no-terminal and without having
to retrieve log messages manually with the client API. The log level is
hardcoded to -v. A higher log level would lead to too much log output
(huge file sizes and latency issues due to waiting on the disk), and
isn't too useful in general anyway. For debugging, the terminal can be
used instead.

wm4 f033eaff9b options: make --hls-bitrate=max the default
The previous default ("no") seemed to be equivalent to "min" in practice
(though it might depend on the website, which is even worse).

Better just select the best stream by default.

wm4 6b24cb2756 win32: remove check for SetPriorityClass()
This function is always available, which is reflected by the fact that
the configure check doesn't actually bother to check for its existence.
Instead, MinGW and Cygwin imply it. The check was probably "needed" when
the priority code was still in a separate source file.

Remove the check, and use _WIN32 for testing for the win32 API (in a
bunch of other places too).

wm4 1883b7cc0c player: add --autofit-smaller option
Fixes #1472.

--autofit-smaller for symmetry.)

wm4 b26087f6f3 options: don't cut off long options in --list-options

wm4 067bb9605c sub: add option to not scale subtitles with window
--sub-scale-by-window=no attempts to keep subs always at the same pixel
size.

The implementation is a bit all over the place, because it compensates
already done scaling by an inverse scale factor, but it will probably do
its job.

Fixes #1424. (The semantics and name of --sub-scale-with-window are
kept, and this adds a new option - the name is confusingly similar, but
it's actually analogue to --osd-scale-by-window.)

wm4 c4f39d2aba build: rename MPLAYER_CONFDIR define
We certainly don't use the mplayer configuration dir. The name didn't

wm4 7297c88998 player: capitalize --display-tags items
Tags keys are case-insensitive. Before commit 8048374a, the casing of
whatever FFmpeg returned was used (it was quite random). But since the
change, the values in --display-tags decides. Consider this an
accidental feature, and make the output nicer by capitalizing
the tag names.

wm4 8048374a5c player: filter tags, add --display-tags option
This attempts to increase user-friendliness by excluding useless tags.
It should be especially helpful with mp4 files, because the FFmpeg mp4
demuxer adds tons of completely useless information to the metadata.

Fixes #1403.

wm4 af3bbb800d audio: make native channel count the default instead of stereo downmix
This should work well with most audio APIs, except ALSA. A long-winded
explanation is provided how to make ALSA multichannel output work.

All other AOs should have no such problems. Of course it's possible
that previously unknown issues arise, because I assume that enabling
multichannel audio is actually relatively rare.

This also disables codec downmix by default, which could change the
audio output due to different mixing in the codec and libavresample.

Fixes #1313.

The --keep-open behavior was recently changed to act only on the last

was useful too, so bring it back as an additional mode.

wm4 d1aabb6316 m_option: never return NOPTS value as number from properties
MP_NOPTS_VALUE (basically INT64_MIN) is basically an special timestamp
value that means "unset" or "unknown". Its exact value is internal, and
should never be returned or interpreted by any API.

So return "no" instead (what is also what the parser accepts).

wm4 ef709d19d4 options: --wid can be set at any time
After being bitten by this, I decided that this mostly unnecessary
requirement sucks.

Allowing this makes it easier to use libmpv, because it can be set after
mpv_initialize(). The latest reasonable time an API user can set this
variable is before actually loading a file.

The previous 2 commits make sure nothing bad can happen if the option is
changed at runtime even if a VO is active. The Cocoa backend should be
fine and doesn't need a change.

wm4 52c51149db options: fix channel map options sometimes failing
Channel amp otpions were not copied correctly: it copied the size of a
pointer to struct chmap, not the struct itself. Since mp_chmap is
currently 9 bytes, this meant the last channel entry was not copied
correctly on 64 bit systems, leading to very strange failures. It could
be triggered especially when using the client API, because the client
API always copies options on access (mpv command line options tend to
work directly on options).

wm4 cc54377463 Do not call strerror()
...because everything is terrible.

strerror() is not documented as having to be thread-safe by POSIX and
C11. (Which is pretty much bullshit, because both mandate threads and
some form of thread-local storage - so there's no excuse why
implementation couldn't implement this in a thread-safe way. Especially
with C11 this is ridiculous, because there is no way to use threads and
convert error numbers to strings at the same time!)

Since we heavily use threads now, we should avoid unsafe functions like
strerror().

strerror_r() is in POSIX, but GNU/glibc deliberately fucks it up and
gives the function different semantics than the POSIX one. It's a bit of
work to convince this piece of shit to expose the POSIX standard
function, and not the messed up GNU one.

strerror_l() is also in POSIX, but only since the 2008 standard, and
thus is not widespread.

The solution is using avlibc (libavutil, by its official name), which
handles the unportable details for us, mostly. We avoid some pain.

wm4 4bd6c91d9b command: implement A-B loops
Probably needs to be polished a bit more. Also, might require a key

For now, something like this can be put into input.conf to use it:

ctrl+y set ab-loop-a ${time-pos}    # set A
ctrl+x set ab-loop-b ${time-pos}    # set B
ctrl+c set ab-loop-a no             # clear (mostly)

wm4 a6694d2788 demux_mkv: adjust subtitle preroll again (2)
Make the changes started in commit c827ae5f more eloborate, and provide
an option to control the amount of data read before the seek-target. To
achieve this, rewrite the loop that finds the lowest still acceptable
target cluster. It is now searched by time instead of file position. The
behavior (both with and without preroll option) may be different from
before this change, although it shouldn't be worse.

The change demux_mkv_read_cues() fixes a bug: when seeking after playing
normally, the code would erroneously assume that durations are set. This
doesn't happen if the first operation after loading was a seek instead
of playback.

No development activity (or even any sign of life) for almost a year.

next mpv release. Ask on the IRC channel if you want to test.

Simplify the Lua check too: libquvi linking against a different Lua
version than mpv was a frequent issue, but with libquvi gone, no
direct dependency uses Lua, and such a clash is rather unlikely.

wm4 a037f7b464 terminal: strictly don't read terminal input if stdout is not a terminal
Doing that doesn't make sense anyway: it's meant for interactive input,
and if the output of the player is not on the terminal, how will you
interact with it?

It was also quite in the way when trying to read verbose output with
e.g. less while the player was running, because the player would grab
half of all input meant for less (simply because stdin is still
connected to the terminal).

Remove the now redundant special-casing of pipe input.

Add some dirty workarounds to hide mp_stat() from the normal code
properly. This now requires replacing all functions that use the

others. (mpv currently uses stat and fstat only.)

wm4 ae2e2b9740 audio: enable pitch correction by default when playing fast

wm4 4ea05577bd audio: remove --audiodrop
This would play some silence in case video was slower than audio. If
framedropping is already enabled, there's no other way to keep A/V
sync, short of changing audio playback speed (which would give worse
results). The --audiodrop option inserted silence if there was more
than 500ms desync.

This worked somewhat, but I think it was a silly idea after all. Whether
the playback experience is really bad or slightly worse doesn't really
matter. There also was a subtle bug with PTS handling, that apparently
caused A/V desync anyway at ridiculous playback speeds.

Just remove this feature; nobody is going to use it anyway.

wm4 ea2b19f646 player: allow overriding OSD message for all OSD levels
Until now, you could override only level 3 with --osd-status-msg. Extend
this, add add --osd-msg1 to --osd-msg3 (one for each OSD level). OSD
level 0 always means disable OSD, so that isn't included.

--osd-msg3 corresponds to --osd-status-msg, but they're not exactly the
same. To allow more customization, --osd-msgN do not include the OSD
symbol. The symbol can be manually added with "${osd-sym-cc}". We keep
the "old" option for some short-term compatibility.

--osd-msg1 should be particularly useful; for example you could do:

    --osd-msg1='${?pause==yes:${osd-sym-cc}}'

to display a "paused" symbol when paused, and nothing during normal
playback. (Although admittedly, the syntax is quite a bit of work.)

wm4 0aaf688c2d command: make m_property_strdup_ro with NULL mean unavailable
This catches a few cases which basically call:

    m_property_strdup_ro(..., ..., NULL)

which would return NULL strings. This should generally be avoided
(although it's allowed due to reasons), and it seems most callers
actually intend this to mean M_PROPERTY_UNAVAILABLE.

wm4 8599c959fe video: initial Matroska 3D support
This inserts an automatic conversion filter if a Matroska file is marked
as 3D (StereoMode element). The basic idea is similar to video rotation
and colorspace handling: the 3D mode is added as a property to the video
params. Depending on this property, a video filter can be inserted.

As of this commit, extending mp_image_params is actually completely
unnecessary - but the idea is that it will make it easier to integrate
with VOs supporting stereo 3D mogrification. Although vo_opengl does
support some stereo rendering, it didn't support the mode my sample file
used, so I'll leave that part for later.

Not that most mappings from Matroska mode to vf_stereo3d mode are
probably wrong, and some are missing.

Assuming that Matroska modes, and vf_stereo3d in modes, and out modes
are all the same might be an oversimplification - we'll see.

See issue #1045.

wm4 829fdef219 player: reduce default demuxer cache
A (hopefully) temporary hack to make stream switching delays tolerable.
It's not clear how this should be handled (either executing a precise
seek on track switching, or always enabling all streams), so get this
issue out of the way for now by picking a rather low value.

wm4 68ff8a0484 Move compat/ and bstr/ directory contents somewhere else
bstr.c doesn't really deserve its own directory, and compat had just
a few files, most of which may as well be in osdep. There isn't really
any justification for these extra directories, so get rid of them.

The compat/libav.h was empty - just delete it. We changed our approach
to API compatibility, and will likely not need it anymore.

wm4 0b428e4482 player: redo how stream caching and pausing on low cache works
Add the --cache-secs option, which literally overrides the value of
--demuxer-readahead-secs if the stream cache is active. The default
value is very high (10 seconds), which means it can act as network
cache.

Remove the old behavior of trying to pause once the byte cache runs
low. Instead, do something similar wit the demuxer cache. The nice
thing is that we can guess how many seconds of video it has cached,
and we can make better decisions. But for now, apply a relatively
naive heuristic: if the cache is below 0.5 secs, pause, and wait
until at least 2 secs are available.

Note that due to timestamp reordering, the estimated cached duration
of video might be inaccurate, depending on the file format. If the
file format has DTS, it's easy, otherwise the duration will seemingly
jump back and forth.

wm4 b822faa6cf demux: add option to control the readahead buffer by a duration value
--demuxer-readahead-secs now controls how much the demuxer should
readahead by an amount of seconds. This is based on the raw packet
timestamps. It's not always very exact. For example, h264 in Matroska
does not store any linear timestamps (only PTS values which are going
to be reordered by the decoder), so this heuristic is usually off by
several hundred milliseconds.

The decision whether to readahead is basically OR-ed with the other
--demuxer-readahead-packets options. Change the manpage descriptions
to subtly convey these semantics.

wm4 4f984b987c video: add --display-fps switch to control framedrop FPS
Since the display FPS is currently detected on X11 only (and even there
it's known to be wrong on certain setups), it seems like a good idea to
make this user-configurable.

wm4 07aba86b37 audio: add a mode to insert silence on severe A/V desync

wm4 543ba6c114 video: add VO framedropping mode
This mostly uses the same idea as with vo_vdpau.c, but much simplified.

On X11, it tries to get the display framerate with XF86VM, and limits
the frequency of new video frames against it. Note that this is an old
extension, and is confirmed not to work correctly with multi-monitor
setups. But we're using it because it was already around (it is also
used by vo_vdpau).

This attempts to predict the next vsync event by using the time of the
last frame and the display FPS. Even if that goes completely wrong,
the results are still relatively good.

On other systems, or if the X11 code doesn't return a display FPS, a
framerate of 1000 is assumed. This is infinite for all practical
purposes, and means that only frames which are definitely too late are
dropped. This probably has worse results, but is still useful.

"--framedrop=yes" is basically replaced with "--framedrop=decoder". The
old framedropping mode is kept around, and should perhaps be improved.
Dropping on the decoder level is still useful if decoding itself is too
slow.

wm4 df58e82237 video: move display and timing to a separate thread
The VO is run inside its own thread. It also does most of video timing.
The playloop hands the image data and a realtime timestamp to the VO,
and the VO does the rest.

In particular, this allows the playloop to do other things, instead of
blocking for video redraw. But if anything accesses the VO during video
timing, it will block.

This also fixes vo_sdl.c event handling; but that is only a side-effect,
since reimplementing the broken way would require more effort.

Also drop --softsleep. In theory, this option helps if the kernel's
sleeping mechanism is too inaccurate for video timing. In practice, I
haven't ever encountered a situation where it helps, and it just burns
CPU cycles. On the other hand it's probably actively harmful, because
it prevents the libavcodec decoder threads from doing real work.

Side note:

Originally, I intended that multiple frames can be queued to the VO. But
this is not done, due to problems with OSD and other certain features.
OSD in particular is simply designed in a way that it can be neither
timed nor copied, so you do have to render it into the video frame
before you can draw the next frame. (Subtitles have no such restriction.
sd_lavc was even updated to fix this.) It seems the right solution to
queuing multiple VO frames is rendering on VO-backed framebuffers, like
vo_vdpau.c does. This requires VO driver support, and is out of scope
of this commit.

As consequence, the VO has a queue size of 1. The existing video queue
is just needed to compute frame duration, and will be moved out in the
next commit.

wm4 aa1a383342 sub: add detection via BOM
Useful for Windows stuff. Actually, ENCA support should catch this, but,
well, whatever, everyone seems to hate ENCA.

Detection with BOM is trivial, although it needs some hackery to
integrate it with the existing autodetection support. For one, change
the default value of --sub-codepage to make this easier.

Probably fixes issue #937 (the second part).

wm4 1301a90761 demux: add a demuxer thread
This adds a thread to the demuxer which reads packets asynchronously.
It will do so until a configurable minimum packet queue size is
reached. (See options.rst additions.)

For now, the thread is disabled by default. There are some corner cases
that have to be fixed, such as fixing cache behavior with webradios.

Note that most interaction with the demuxer is still blocking, so if
e.g. network dies, the player will still freeze. But this change will
make it possible to remove most causes for freezing.

Most of the new code in demux.c actually consists of weird caches to
compensate for thread-safety issues (with the previously single-threaded
design), or to avoid blocking by having to wait on the demuxer thread.

Most of the changes in the player are due to the fact that we must not
access the source stream directly. the demuxer thread already accesses
it, and the stream stuff is not thread-safe.

For timeline stuff (like ordered chapters), we enable the thread for the
current segment only. We also clear its packet queue on seek, so that
the remaining (unconsumed) readahead buffer doesn't waste memory.

Keep in mind that insane subtitles (such as ASS typesetting muxed into
mkv files) will practically disable the readahead, because the total
queue size is considered when checking whether the minimum queue size
was reached.
