[FFmpeg-devel] [PATCH] avformat/mov: fix hang while seek on a kind of fragmented mp4.

[C.H.Liu]

I have updated a new patch that has passed valgrind as follows:
*$ ./configure --samples=fate-suite/ --disable-doc --fatal-warnings
--valgrind=VALGRIND*
*$ make -j4 && make fate-mov*
But I never encountered a ‘stream 0, timescale not set’ log in here. Please
let me know if you have any questions.
Sorry for the previous trouble.

Thanks and Regards,
Charles Liu
