Hey guys~

I am trying to decode video stream with RTP, when I put all the *receive
packets ->assemble into a whole frame -> decode and display stuff in one
thread*,everything seems fine with some delay,then

I try to do multi-thread with one thread to receive to receive and assemble
packets another to decode and play..But I *got avcodec_decode_video failed
all the time*, with pthread_mutex_lock

assistance I think crucial data struct is safe and I have checked every
parameters avcodec_decode_video evey takes, seems normal...No luck with
avcodec_decode_video2 too.......

I am completely clueless, any tips and suggestion would be appreciated !!

Thanks in advance ~

Cheers
