c++ - Error in ffmpeg when reading from UDP stream -

i'm trying process frames udp stream using ffmpeg. run fine while av_read_frame() return either averror_exit (immeditate exit requested) or -5 (error number -5 occurred) while stream should still running fine. right before error prints following message console

[mpeg2video @ 0caf6600] ac-tex damaged @ 14 10 [mpeg2video @ 0caf6600] warning mvs not available [mpeg2video @ 0caf6600] concealing 800 dc, 800 ac, 800 mv errors in frame 

(the numbers in message vary run run)

i have suspicion error related calling av_read_frame quickly. if have run fast possible, error within 10-20 frames, if put sleep before reading run fine minute or , exit error. realize hacky , assume there better solution. bottom line: there way dynamically check if 'av_read_frame()' ready called? or way supress error?

psuedo code of i'm doing below. in advance help!

void getframe() {     //wait here?? seems hacky...     //boost::this_thread::sleep(boost::posix_time::milliseconds(25));         int av_read_frame_error = av_read_frame(m_input_format_context, &m_input_packet);                if(av_read_frame_error == 0){                //do stuff - works fine when gets here     }     else{                        //error         char errorbuf[av_error_max_string_size];         av_make_error_string(errorbuf, av_error_max_string_size, av_read_frame_error);         cout << "ffmpeg input stream exit code: " << av_read_frame_error << "   message: " << errorbuf << endl;                  } } 

incoming frames needs handled in callback function. mechanism should such callback gets called whenever there new frame. in way there no need manually fine tune delay.

disclaimer: have not used ffmpeg apis.
