FFmpeg version 7.0 CLI introduces a native decoder for the H266 codec (VVC) and supports Immersive Audio, offers multi-threaded conversion, loopback decoders, new filters like a QR code overlay, and removes deprecated APIs like -map_channel.
To leverage FFmpeg's multi-threaded conversion, multiple input sources and/or output destinations are needed. Loopback decoders allow feeding processed pre-muxing output streams back as input. New filters include one placing dynamically generated QR codes over videos.
Compiling FFmpeg 7 from source requires manual adjustments for accessing new features like the QR code filter, beyond standard compilation steps from the official FFmpeg wiki for external libraries.
Studying the configure file in the ffmpeg_source directory can help enable external libraries not automatically detected for the compilation of FFmpeg CLI, ensuring access to new functionalities in version 7.
