• FFMPEG : cannot play MPEG4 video encoded from images. Duration and bitrate undefined

  17 juin 2013, par KaiK

  I've been trying to set a H264 video stream created from images, into an MPEG4 container. I've been able to get the video stream from images successfully. But when muxing it in the container, I must do something wrong because no player is able to reproduce it, despite ffplay - that plays the video until the end and after that, the image gets frozen until the eternity -.

  The ffplay cannot identify Duration neither bitrate, so I supose it might be an issue related with dts and pts, but I've searched about how to solve it with no success.

  Here's the ffplay output :

  Structure

  My code is C++ styled, so I've a class that handles all the encoding, and then a main that initilize it, passes some images in a bucle, and finally notify the end of the process as following :

  int main (int argc, const char * argv[])
  
  {
  
  
  
  MyVideoEncoder* videoEncoder = new MyVideoEncoder(512, 512, 512, 512, "output/testContainer.mp4", 25, 20);
  
  if(!videoEncoder->initWithCodec(MyVideoEncoder::H264))
  
  {
  
      std::cout << "something really bad happened. Exit!!" << std::endl;
  
      exit(-1);
  
  }
  
  
  
  /* encode 1 second of video */
  
  for(int i=0;i<228;i++) {
  
  
  
      std::stringstream filepath;
  
      filepath << "input2/image" << i << ".jpg";
  
  
  
      videoEncoder->encodeFrameFromJPG(const_cast(filepath.str().c_str()));
  
  
  
  }
  
  
  
  videoEncoder->endEncoding();
  
  
  
  }

  Hints

  I've seen a lot of examples about decoding of a video and encoding into another, but no working example of muxing a video from the scratch, so I'm not sure how to proceed with the pts and dts packet values. That's the reason why I suspect the issue must be in the following method :

  bool MyVideoEncoder::encodeImageAsFrame(){
  
      bool res = false;
  
  
  
  
  
      pTempFrame->pts = frameCount * frameRate * 90; //90Hz by the standard for PTS-values
  
      frameCount++;
  
  
  
      /* encode the image */
  
      out_size = avcodec_encode_video(pVideoStream->codec, outbuf, outbuf_size, pTempFrame);
  
  
  
  
  
      if (out_size > 0) {
  
          AVPacket pkt;
  
          av_init_packet(&pkt);
  
          pkt.pts = pkt.dts = 0;
  
  
  
          if (pVideoStream->codec->coded_frame->pts != AV_NOPTS_VALUE) {
  
              pkt.pts = av_rescale_q(pVideoStream->codec->coded_frame->pts,
  
                      pVideoStream->codec->time_base, pVideoStream->time_base);
  
              pkt.dts = pTempFrame->pts;
  
  
  
          }
  
          if (pVideoStream->codec->coded_frame->key_frame) {
  
              pkt.flags |= AV_PKT_FLAG_KEY;
  
          }
  
          pkt.stream_index = pVideoStream->index;
  
          pkt.data = outbuf;
  
          pkt.size = out_size;
  
  
  
          res = (av_interleaved_write_frame(pFormatContext, &pkt) == 0);
  
      }
  
  
  
  
  
      return res;
  
  }

  Any help or insight would be appreciated. Thanks in advance !!

• FFMPEG : cannot play MPEG4 video encoded from images. Duration and bitrate undefined

  Structure

  My code is C++ styled, so I've a class that handles all the encoding, and then a main that initilize it, passes some images in a bucle, and finally notify the end of the process as following :

  int main (int argc, const char * argv[])
  
  {
  
  
  
  MyVideoEncoder* videoEncoder = new MyVideoEncoder(512, 512, 512, 512, "output/testContainer.mp4", 25, 20);
  
  if(!videoEncoder->initWithCodec(MyVideoEncoder::H264))
  
  {
  
      std::cout << "something really bad happened. Exit!!" << std::endl;
  
      exit(-1);
  
  }
  
  
  
  /* encode 1 second of video */
  
  for(int i=0;i<228;i++) {
  
  
  
      std::stringstream filepath;
  
      filepath << "input2/image" << i << ".jpg";
  
  
  
      videoEncoder->encodeFrameFromJPG(const_cast(filepath.str().c_str()));
  
  
  
  }
  
  
  
  videoEncoder->endEncoding();
  
  
  
  }

  Hints

  I've seen a lot of examples about decoding of a video and encoding into another, but no working example of muxing a video from the scratch, so I'm not sure how to proceed with the pts and dts packet values. That's the reason why I suspect the issue must be in the following method :

  bool MyVideoEncoder::encodeImageAsFrame(){
  
      bool res = false;
  
  
  
  
  
      pTempFrame->pts = frameCount * frameRate * 90; //90Hz by the standard for PTS-values
  
      frameCount++;
  
  
  
      /* encode the image */
  
      out_size = avcodec_encode_video(pVideoStream->codec, outbuf, outbuf_size, pTempFrame);
  
  
  
  
  
      if (out_size > 0) {
  
          AVPacket pkt;
  
          av_init_packet(&pkt);
  
          pkt.pts = pkt.dts = 0;
  
  
  
          if (pVideoStream->codec->coded_frame->pts != AV_NOPTS_VALUE) {
  
              pkt.pts = av_rescale_q(pVideoStream->codec->coded_frame->pts,
  
                      pVideoStream->codec->time_base, pVideoStream->time_base);
  
              pkt.dts = pTempFrame->pts;
  
  
  
          }
  
          if (pVideoStream->codec->coded_frame->key_frame) {
  
              pkt.flags |= AV_PKT_FLAG_KEY;
  
          }
  
          pkt.stream_index = pVideoStream->index;
  
          pkt.data = outbuf;
  
          pkt.size = out_size;
  
  
  
          res = (av_interleaved_write_frame(pFormatContext, &pkt) == 0);
  
      }
  
  
  
  
  
      return res;
  
  }

  Any help or insight would be appreciated. Thanks in advance !!
