• Youtube stream of looping JPG stops randomly

  6 juillet 2021, par timw99

  Hi I'm fairly new at ffmpeg.

  


  I'm currently trying to get a low FPS Youtube stream working over RTMP using a JPG on loop which content gets changed using a NodeJS script periodically. I'm using the following command to stream (variable 3 is my stream key) :

  


  ffmpeg -re -loop 1 -pix_fmt bgr24 -framerate 5 -i img/now.jpg -re -stream_loop -1 -i output.mp3 -f flv -vcodec libx264 -profile:v main -g 60 -keyint_min 30 -b:v 400k -minrate 400k -maxrate 400k -preset ultrafast -tune zerolatency -bufsize 2000k rtmp://a.rtmp.youtube.com/live2/$3


  


  There's multiple things wrong here. The bitrate doesn't actually stay at 400k/s. It just goes to around 200-1000k and then just starts decreasing until the stream stops (usually at around 200-300k bitrate). It still seems like data is being sent (bitrate and current FPS are still updated (though they're very low) and speed goes parabolic. The frame counter itself just stops and Youtube doesn't continue streaming. See example :

  


  frame=  515 fps=5.0 q=12.0 size=    5803kB time=00:01:42.84 bitrate= 462.3kbits/

  I'm using a Digital Ocean VPS to run it, but the same happens on my own desktop which definitely has the hardware for a simple stream like this. Could it have something to do with me replacing the JPG content while trying to stream it ? I get this error every once in a while, but it seems like it fixes itself judging by the info :

  


  [mjpeg @ 0x562824d1fb40] overread 8
[mjpeg @ 0x562824d1fb40] EOI missing, emulating


  


  I can provide more information if it's needed. Thanks in advance.

  


• Getting artifacts when trying to read video stream from YouTube

  23 février 2012, par givi

  I'm trying to read the video frames from the RTSP stream that I get from YouTube. Here is the link for my test video :

  rtsp ://v8.cache5.c.youtube.com/CiILENy73wIaGQkJlrXMiAG8BxMYDSANFEgGUgZ2aWRlb3MM/0/0/0/video.3gp

  If I'm reading frames from the local file - everything is fine, but when read them from a stream I get nothing but lots of artifacts. I've googled around and found out that there might be a problem with UDP packets and switching to TCP may help but I really can't find where it is possible to change this.

  Here is the function for reading a frame :

  bool nextFrame(AVFormatContext *pFormatCtx, AVCodecContext *pCodecCtx, int videoStream, AVFrame *pFrame) {  AVPacket packet;
  
      int frameFinished = 0;
  
  
  
      while( !frameFinished && av_read_frame(pFormatCtx, &packet) >= 0 ) {
  
          // Is this a packet from the video stream?
  
          if( packet.stream_index == videoStream ) {
  
              // Decode video frame
  
              avcodec_decode_video2(pCodecCtx, pFrame, &frameFinished, &packet);
  
          }
  
  
  
          // Free the packet that was allocated by av_read_frame
  
          av_free_packet(&packet);    
  
         }    
  
         return frameFinished!=0;  
  
  }

  I'm also getting lots of error messages in my log :

  [h263 @ 0x7804c00] warning: first frame is no keyframe
  
  [h263 @ 0x7804c00] illegal ac vlc code at 6x1

  ...and so on

  edit : this is 99.9% a UDP-TCP problem. I've found this link :

  rtsp ://195.200.199.8/mpeg4/media.amp

  This is some test camera available online. It streams with artifacts. However if it has get parameter 'tcp' and if I use this

  rtsp ://195.200.199.8/mpeg4/media.amp ?tcp

  everything works without artifacts.

  So to correct my question : is there any way to force YouTube or ffmpeg to use TCP ?
