Description Gianluca Gabrielli 2021-08-06 08:17:06 UTC
Prior to ffmpeg version 4.3, the tty demuxer did not have a 'read_probe'
function assigned to it. By crafting a legitimate "ffconcat" file that
references an image, followed by a file the triggers the tty demuxer, the
contents of the second file will be copied into the output file verbatim (as
long as the `-vcodec copy` option is passed to ffmpeg).
