ffmpeg-trac is the mailing list only for receiving all bug reports,
comments, and status changes made on the bug tracker.
If you need help send a message to the ffmpeg-user mailing list. Make
sure you include your actual command, the complete console output, and
provide links to any inputs if they are required for others to duplicate
Since I assume you're using the concat demuxer also show the complete
info for each input: ffmpeg -i video -i slate
