pulled the following error [matroska @ 0x7fb16b000e00] Codec for stream 1 does not use global headers but container format requires global headers [matroska @ 0x7fb16b000e00] Raw RGB is not supported Natively in Matroska, you can use AVI or NUT or If you would like to store it anyway using VFW mode, enable allow_raw_vfw (-allow_raw_vfw 1) /snip/ Could not write header for output file #0 (incorrect codec parameters ?): Invalid argument but $ ffmpeg -ss 0 -lowres 1 -i video.mxf -i audio.mxf -f nut -c:a copy -c:v rawvideo - | ffplay - seems to work well.
