Andreas Rheinhardt 7539a01bb0 avcodec/videotoolboxenc: Avoid copying data, allow user-supplied buffers Here the packet size is known before allocating the packet because the encoder provides said information (and works with internal buffers itself), so one use this information to avoid the implicit use of another intermediate buffer for the packet data; and by switching to ff_get_encode_buffer() one can also allow user-supplied buffers.

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.
Additional small tools such as aviocat, ismindex and qt-faststart.
