[Libav-user] segmetation fault while avcodec_encode_video2

[itwasntpete]

hi guy's,

i have a problem with the avcodec_encode_video2. i grab a frame from my camera and want to write that into a stream. but avcodec_encode_video2 is generating a segmentation fault.

the main loop is quit simple:

 

 

      for(;;) {

        if(av_read_frame(formatCtxIn, pktIn) >= 0) {

          av_dup_packet(pktIn);

 

          int fff;

          if(avcodec_decode_video2(codecCtxIn, frame, &fff, pktIn) < 0)

            std::cout << "shit frame" << std::endl;

 

          if(!fff)

            return 0;  // ok

 
                  // segmentation fault

          if(avcodec_encode_video2(streamOut->codec, pktOut, frame, &fff) < 0)

            std::cout << "shit frame" << std::endl;

        }

      }

 

do anybody has any advice for me, why this is happening.
