Comment (by lavv17):
It looks like a problem with format auto-detection. s->priv_data is not
correctly allocated at util.c:577 (with priv_data_size=5912), but later it
is assumed to be MpegTSContext and sizeof(MpegTSContext) = 73848, thus it
overwrites memory past allocated buffer.
When I run ffmpeg with explicit "-f mpegts" it correctly allocates
priv_data_size=73848 and does not crash.
