View Source Membrane.MP4.Muxer.CMAF (Membrane MP4 plugin v0.16.2)

Puts payloaded stream into Common Media Application Format, an MP4-based container commonly used in adaptive streaming over HTTP.

Multiple input streams are supported. If that is the case, they will be muxed into a single CMAF Track. Given that all input streams need to have a keyframe at the beginning of each CMAF Segment, it is recommended that all input streams are renditions of the same content.

If a stream contains non-key frames (like H264 P or B frames), they should be marked with a mp4_payload: %{key_frame?: false} metadata entry.
