Replace FFmpeg with Libav in licence headers
Signed-off-by: Mans Rullgard <email@example.com>
Prefix all _demuxer, _muxer, _protocol from libavformat and libavdevice.
This also lists the objects from those two libraries as internal (by addingthe ff_ prefix) so that they can then be hidden via linker scripts.
Add MD5 protocol
This is a write-only protocol which computes the md5sum of data written,and on close writes this to the designated output or stdout if noneis specified. It can be used to test muxers without writing an actualfile.
