| ConfigVariableBool | ffmpeg_global_lock ("ffmpeg-global-lock", false, PRC_DESC("Set this true to enable a single global mutex across *all* ffmpeg " "operations. Leave this false to use the mutex only for " "the ffmpeg operations that are generally known to be " "not thread-safe. This will negatively affect ffmpeg performance, " "especially when decoding multiple videos at once (including the " "left and right channels of a stereo video). Set this true only " "if you suspect a problem with ffmpeg's own thread-safe nature.")) |
| ConfigVariableInt | ffmpeg_max_readahead_frames ("ffmpeg-max-readahead-frames", 2, PRC_DESC("The maximum number of frames ahead which an ffmpeg decoder thread " "should read in advance of actual playback. Set this to 0 to " "decode ffmpeg videos in the main thread.")) |
| ConfigVariableBool | ffmpeg_prefer_libvpx ("ffmpeg-prefer-libvpx", false, PRC_DESC("If this is true, Panda will overrule ffmpeg's best judgment on " "which decoder to use for decoding VP8 and VP9 files, and try to " "choose libvpx. This is useful when you want to play WebM videos " "with an alpha channel, which aren't supported by ffmpeg's own " "VP8/VP9 decoders.")) |
| ConfigVariableInt | ffmpeg_read_buffer_size ("ffmpeg-read-buffer-size", 4096, PRC_DESC("The size in bytes of the buffer used when reading input files. " "This is important for performance. A typical size is that of a " "cache page, e.g. 4kb.")) |
| ConfigVariableBool | ffmpeg_show_seek_frames ("ffmpeg-show-seek-frames", true, PRC_DESC("Set this true to allow showing the intermediate results of seeking " "through the ffmpeg stream to a target frame, or false to hold the " "current frame until the target frame is achieved. This has the " "biggest effect on videos that are too expensive to decode in real " "time: when this is true, the video can be seen to animate at least " "a little bit; when it is false, you may get long periods of one " "held frame.")) |
| ConfigVariableBool | ffmpeg_support_seek ("ffmpeg-support-seek", true, PRC_DESC("True to use the av_seek_frame() function to seek within ffmpeg " "video files. If this is false, Panda will only seek within a " "file by reading it from the beginning until the desired point, " "which can be much slower. Set this false only if you suspect " "a problem with av_seek_frame().")) |

| void init_libffmpeg | ( | ) |
Initializes the library.
This must be called at least once before any of the functions or classes in this library can be used. Normally it will be called by the static initializers and need not be called explicitly, but special cases exist.
