@John Curtis Both commands throw up the same error message: [matroska @ 0x7fdaabf0a2c0] Only audio, video, and subtitles are supported for Matroska. [out#0/matroska @ 0x7fdaabf07340] Could not write header (incorrect codec parameters ?): Invalid argument [af#0:1 @ 0x7fdaabf0fec0] Error sending frames to consumers: Invalid argument [af#0:1 @ 0x7fdaabf0fec0] Task finished with error code: -22 (Invalid argument) [af#0:1 @ 0x7fdaabf0fec0] Terminating thread with return code -22 (Invalid argument) [out#0/matroska @ 0x7fdaabf07340] Nothing was written into output file, because at least one of its streams received no packets. I can’t post a link to an example file here because I don’t have the rights to do that, and I can’t make an excerpt that still has the timecode track … it’s a catch 22 :) > On 2.
