Build

How to build and use ffmpeg.

./configure
make

Examples:

make examples
cd doc/examples
./some-example
  • decoding_encoding.c: generate synthetic audio and video, encode and decode
  • muxing.c: generate synthetic audio and video, and put them together into a single container output file. Detects format from file extension with avformat_alloc_output_context2.

Codecs

Only a few codecs are included by default.

Build with H264 support:

sudo apt-get install libx264-dev
./configure \
	--enable-gpl \
    --enable-parser=h264 \
	--enable-libx264 \
	--enable-encoder=libx264 \
	--enable-decoder=h264

--enable-gpl is required here, because libx264 http://www.videolan.org/developers/x264.html from VideoLAN is GPL. I think this option excludes non-GPL compatible codecs. Lol, this domain is so patent ridden that it is necessary to manage that from the build script. See also: https://www.ffmpeg.org/legal.html

The following options also seem interesting: TODO what do they do?

--enable-gpl --enable-version3 --enable-nonfree --enable-libvpx --enable-libvorbis
