Aman Gupta 9519983c0f avcodec/videotoolbox: use decode_params to propagate H264 PPS changes and restart on SPS changes This fixes decoding of H264 video samples with SPS and PPS changes. See for example https://s3.amazonaws.com/tmm1/videotoolbox/spschange.ts, which previously stalled the decoder and failed to produce any new frames after the SPS change. Also see https://s3.amazonaws.com/tmm1/videotoolbox/ppschange.ts, which uses multiple PPS and would previously cause VT decode failures. If the VideoToolbox session needs to be restarted, and videotoolbox_start() fails for some reason (for instance, if the video is interlaced and the decoder is running on iOS), avcodec will return AVERROR_EXTERNAL. This can be used by the API user to switch to another decoder. Signed-off-by: Aman Gupta <aman@tmm1.net>		7 years ago

FFmpeg README

FFmpeg is a collection of libraries and tools to process multimedia content such as audio, video, subtitles and related metadata.

Libraries

libavcodec provides implementation of a wider range of codecs.
libavformat implements streaming protocols, container formats and basic I/O access.
libavutil includes hashers, decompressors and miscellaneous utility functions.
libavfilter provides a mean to alter decoded Audio and Video through chain of filters.
libavdevice provides an abstraction to access capture and playback devices.
libswresample implements audio mixing and resampling routines.
libswscale implements color conversion and scaling routines.

Tools

ffmpeg is a command line toolbox to manipulate, convert and stream multimedia content.
ffplay is a minimalistic multimedia player.
ffprobe is a simple analysis tool to inspect multimedia content.
ffserver is a multimedia streaming server for live broadcasts.
Additional small tools such as aviocat, ismindex and qt-faststart.

Documentation

The offline documentation is available in the doc/ directory.

The online documentation is available in the main website and in the wiki.
