Is it better now? I think this is indeed very important, thank you for
letting me know.
Regarding the decoding h264 in a multithreadead manner, is there anyone
who can tell me if it's possible directly from libavocodec or shoud I do
some wrappers (as I orginally thought)?
I also called the function avcodec_thread_init function before
avcodec_open function, no improvement in time decoding frame, still > 50
