View Source Membrane.FFmpeg.Transcoder (Membrane FFmpeg Transcoder Plugin v1.2.0)

Tasks as input an unparsed stream and provides on each pad an unparsed, transcoded stream with the desired properties.

Input might be MPEG-TS or FLV but other streaming containers might work as well. If the input stream contains more than 1 video and 1 audio stream, which one will be picked is undefined behaviour.
