It's not easy to tell whether the OSD/subs are empty, or if something is drawn. In general you have to use osd_draw() with a custom callback. If nothing is visible, the callback is never invoked. (The actual reason why this is so "hard" is the implementation of osd_libass.c, which doesn't allow separating rendering and drawing of OSD elements, because all OSD elements share the same ASS_Renderer.) To simplify avoiding copies, make osd_draw_on_image() instead of the caller use mp_image_make_writeable(). Introduce osd_draw_on_image_p(), which works like osd_draw_on_image(), but gets the new image allocation from an image pool. This is supposed to be an optimization, because it reduces the frequency of large allocations/deallocations for image data. The result of this is that the frequency of copies needed in conjunction with vf_sub, screenshots, and vo_lavc (encoding) should be reduced. vf_sub now always does true pass-through if no subs are shown. Drop the pts check from vf_sub. This didn't make much sense. |

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. For more information see the output of ``./configure --help`` for a list of options, or look at the list of enabled and disabled features printed after running ``./configure``. If you think you have support for some feature installed but configure fails to detect it, the file ``config.log`` may contain information about the reasons for the failure. 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 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. Bug reports =========== Please use the `issues 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 ======== You can find us on IRC in ``#mpv-player`` on ``irc.freenode.net`` .. _changes: https://github.com/mpv-player/mpv/blob/master/DOCS/man/en/changes.rst .. _mpv-build: https://github.com/mpv-player/mpv-build .. _homebrew-mpv: https://github.com/mpv-player/homebrew-mpv .. _issues tracker: https://github.com/mpv-player/mpv/issues
