The plan is to make the whole OSD thread-safe, and we start with this. We just put locks on all entry points (fortunately, dec_sub.c and all sd_*.c decoders are very closed off, and only the entry points in dec_sub.h let you access it). I think this is pretty ugly, but at least it's very simple. There's a special case with sub_get_bitmaps(): this function returns pointers to decoder data (specifically, libass images). There's no way to synchronize this internally, so expose sub_lock/sub_unlock functions. To make things simpler, and especially because the lock is sort-of exposed to the outside world, make the locks recursive. Although the only case where this is actually needed (although trivial) is sub_set_extradata(). One corner case are ASS subtitles: for some reason, we keep a single ASS_Renderer instance for subtitles around (probably to avoid rescanning fonts with ordered chapters), and this ASS_Renderer instance is not synchronized. Also, demux_libass.c loads ASS_Track objects, which are directly passed to sd_ass.c. These things are not synchronized (and would be hard to synchronize), and basically we're out of luck. But I think for now, accesses happen reasonably serialized, so there is no actual problem yet, even if we start to access OSD from other threads. |

mpv
Overview
mpv is a movie player based on MPlayer and mplayer2. It supports a wide variety of video file formats, audio and video codecs, and subtitle types.
If you are wondering what's different from mplayer2 and MPlayer you can read more about the changes.
Compilation
Compiling with full features requires development files for several external libraries. Below is a list of some important requirements.
The mpv build system uses waf but we don't store it in your source tree. The script './bootstrap.py' will download the latest version of waf that was tested with the build system.
For a list of the available build options use ./waf configure --help
. If
you think you have support for some feature installed but configure fails to
detect it, the file build/config.log
may contain information about the
reasons for the failure.
NOTE: To avoid cluttering the output with unreadable spam, --help
only shows
one of the two switches for each option. If the option is autodetected by
default, the --disable-***
switch is printed; if the option is disabled by
default, the --enable-***
switch is printed. Either way, you can use
--enable-***
or --disable-**
regardless of what is printed by --help
.
To build the software you can use ./waf build
: the result of the compilation
will be located in build/mpv
. You can use ./waf install
to install mpv
to the prefix after it is compiled.
NOTE: Using the old build system (with ./old-configure
) should still work,
but will be removed in a future version of mpv.
Essential dependencies (incomplete list):
- gcc or clang
- X development headers (xlib, X extensions, libvdpau, libGL, libXv, ...)
- Audio output development headers (libasound, pulseaudio)
- fribidi, freetype, fontconfig development headers (for libass)
- libass
- FFmpeg libraries (libavutil libavcodec libavformat libswscale libpostproc)
- libjpeg
- libquvi if you want to play Youtube videos directly
- libx264/libmp3lame/libfdk-aac if you want to use encoding (has to be explicitly enabled when compiling ffmpeg)
Most of the above libraries are available in suitable versions on normal Linux distributions. However FFmpeg is an exception (distro versions may be too old to work at all or work well). For that reason you may want to use the separately available build wrapper (mpv-build) that first compiles FFmpeg libraries and libass, and then compiles the player statically linked against those.
If you are running Mac OSX and using homebrew we provide homebrew-mpv, an up to date formula that compiles mpv with sensible dependencies and defaults for OSX.
FFmpeg vs. Libav
Generally, mpv should work with the latest release as well as the git version of both FFmpeg and Libav. But FFmpeg is preferred, and some mpv features work with FFmpeg only. See the wiki article about the issue.
Bug reports
Please use the issue tracker provided by GitHub to send us bug reports or feature requests.
Contributing
For small changes you can just send us pull requests through GitHub. For bigger changes come and talk to us on IRC before you start working on them. It will make code review easier for both parties later on.
Contacts
These forms of contact are meant to ask questions about mpv usage, give feedback on mpv and discuss it's development.
If possible, please avoid posting bugs here and use the issue tracker instead.
