-FFMPEG usually comes with several variations of the same coding type, with different pixel format supported. For example, AVC|H264 encoding can use both `libx264` and `libx264_rgb` encoders. If the source data is decoded into RGB by the decoder, the `ffenc` filter will match the `libx264_rgb` encoder as supporting RGB input and AVC format.
