FFmpeg has always been a very experimental and developer-driven project. It is a key component in many multimedia projects and has new features added constantly.
The FFmpeg CLI (we usually reffer to it as ffmpeg.c to avoid confusion) has speed-up improvements due to threading, as well as statistics options, and the ability to pass option values for filters from a file.
The following documentation is regenerated nightly, and corresponds to the newest FFmpeg revision. Consult your locally installed documentation for older versions.
ffmpeg builds a transcoding pipeline out of the components listed below. The program’s operation then consists of input data chunks flowing from the sources down the pipes towards the sinks, while being transformed by the components they encounter along the way.
FFmpeg is the leading multimedia framework, able to decode, encode, transcode, mux, demux, stream, filter and play pretty much anything that humans and machines have created.
Students can discuss an idea with the community via the ffmpeg-devel mailing-list, the #ffmpeg-devel IRC channel, or contact the FFmpeg GSoC admins directly for more information.
Patches should be submitted to the ffmpeg-devel mailing list using git format-patch or git send-email. Github pull requests should be avoided because they are not part of our review process and will be ignored.
FFmpeg guarantees backward API and ABI compatibility for each library as long as its major version number is unchanged. This means that no public symbols will be removed or renamed.
FFmpeg can basically stream through one of two ways: It either streams to a some "other server", which re-streams for it to multiple clients, or it can stream via UDP/TCP directly to some single destination receiver, or alternatively directly to a multicast destination.
Where hardware surfaces are usable, these filters will generally act on them rather than on normal frames in system memory. There are a lot of different APIs of varying standardisation status available. FFmpeg offers access to many of these, with varying support.
