Let me know if there's anything I can do to debug.
The output of transcode at the moment of hangup could help (I'm
specially interested in the counters' value).
To clarify, this means running your commandline with
-q 1
instead of
-q 0
On a side note, if using -q 1 improve the situation (fewer or no
hangup), that's a very bad sign.
Bests,
Ciao Francesco --
The -q 1 does not resolve the hang on my system, still with a
one-minute video:
$ tcprobe -i test.mp4
