[FFmpeg-user] av_find_stream_info takes 20 Sec dvbt.

[Piyush Verma]

Thanks Carl.

I have tried probsize and it helped a bit.

Infact last time my conclusion was wrong.

av_open_input_file is taking 12 to 15 sec.

av_find_stream_info taking 5sec as there probesize was 5000000.

after changing  probsize to 1000000 it save approx 2 sec. But
av_open_input_file is same as before.

I googled and found some thing but it does not work for me.

I have tried  AVFMT_FLAG_IGNIDX.


Any other way to solve this problem?



Thanks & Regards
