• Video too fast FFmpeg

  22 novembre 2012, par Spamdark

  I am having an issue again with ffmpeg, I'm a newbie with ffmpeg, and I can't find a good tutorial up to date...

  This time, when I play a video with ffmpeg, it plays too fast, ffmpeg is ignoring the FPS, I don't want to handle that with a thread sleep, because the videos have differents FPS's.

  I created a thread, there you can find the loop :

  AVPacket framepacket;
  
  
  
  while(av_read_frame(formatContext,&framepacket)>= 0){
  
      pausecontrol.lock();
  
  
  
      // Is it a video or audio frame¿?
  
      if(framepacket.stream_index==gotVideoCodec){
  
          int framereaded;
  
          // Video? Ok
  
          avcodec_decode_video2(videoCodecContext,videoFrame,&framereaded,&framepacket);
  
          // Yeah, did we get it?
  
          if(framereaded && doit){
  
              AVRational millisecondbase = {1,1000};
  
              int f_number = framepacket.dts;
  
              int f_time = av_rescale_q(framepacket.dts,formatContext->streams[gotVideoCodec]->time_base,millisecondbase);
  
              currentTime=f_time;
  
              currentFrameNumber=f_number;
  
  
  
              int stWidth = videoCodecContext->width;
  
              int stHeight = videoCodecContext->height;
  
              SwsContext *ctx = sws_getContext(stWidth, stHeight, videoCodecContext->pix_fmt, stWidth,
  
              stHeight, PIX_FMT_RGB24, SWS_BICUBIC, NULL, NULL, NULL);
  
              if(ctx!=0){
  
              sws_scale(ctx,videoFrame->data,videoFrame->linesize,0,videoCodecContext->height,videoFrameRGB->data,videoFrameRGB->linesize);
  
              QImage framecapsule=QImage(stWidth,stHeight,QImage::Format_RGB888);
  
  
  
              for(int y=0;ydata[0]+y*videoFrameRGB->linesize[0],stWidth*3);
  
              }
  
              emit newFrameReady(framecapsule);
  
              sws_freeContext(ctx);
  
              }
  
  
  
          }
  
      }
  
      if(framepacket.stream_index==gotAudioCodec){
  
          // Audio? Ok
  
      }
  
      pausecontrol.unlock();
  
      av_free_packet(&framepacket);
  
  }

  Any Idea ?

• ffmpeg + ffserver : "Broken ffmpeg default settings detected"

  18 octobre 2012, par Chris Nolet

  I'm just trying to connect ffmpeg to ffserver and stream rawvideo.

  I keep getting the error : broken ffmpeg default settings detected from libx264 and then Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height from ffmpeg before it exits.

  I'm launching ffmpeg with the command : ffmpeg -f x11grab -s 320x480 -r 10 -i :0.0 -tune zerolatency http://localhost:8090/feed1.ffm

  My ffserver.conf file (for ffserver) looks like this :

• Android FFmpeg Video Recording Delete Last Recorded Part

  17 avril 2015, par user3587194

  I’m trying to do exactly what this picture shows.

  Anyway, how can I delete part of a video ? The code I was testing is on github.

  It uses a progress bar so that when you record the progress bar will move, and keep them in separate segments. What is confusing to me is trying to figure out where and how to grab each segment to see if I want to delete that segment or not.

  @Override
  
  public void onPreviewFrame(byte[] data, Camera camera) {
  
  
  
      long frameTimeStamp = 0L;
  
  
  
      if (mAudioTimestamp == 0L && firstTime > 0L)
