Membrane.FFmpeg.Transcoder (Membrane FFmpeg Transcoder Plugin v1.2.6)

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.
