Sebastian Dröge (slomo) has below analysis:

Ok, this fails because "mpegtsbase.c:1328:mpegts_base_scan:<tsdemux0> Couldn't
find any PCR within the first 655360 bytes". Where is the PCR? :)


Can you open another bug against tsdemux for this specific file? Inside
baseparse what should happen probably is to guard against overflows not only in
this place but in general, I don't think your patch is complete here as it
could still overflow (bitrate is still an int).
