It should work on TS files that were recorded on MythTV. If you have
h265 files or mkv files they will appear to be processing but actually
do not create a seek table. I spent some time looking at the possibility
of fixing this, but it requires parse routines to find key frames, and
these have only been written for TS files that are MPEG2 or H264. ffmpeg
apis are not reliable in finding key frames unless you are decoding the
video, and that would be too slow for the rebuild program.
