FFmpeg 101 (2024)

7 hours ago

FFmpeg is a suite of tools and libraries for handling multimedia files.
Key tools include ffmpeg (format conversion), ffplay (media player), and ffprobe (stream analyzer).
Libraries like libavformat, libavcodec, and libavfilter provide core functionalities for multimedia processing.
Basic usage involves demuxing and decoding streams using structures like AVFormatContext, AVStream, and AVCodec.
Example code demonstrates opening a file, analyzing streams, and decoding video frames.
The process includes finding the right codec, configuring the decoder, and processing packets and frames.
Building the example requires meson and ninja, with FFmpeg automatically downloaded if not installed.
