• rtsp timeout av_read_frame

  30 novembre 2012, par user1175197

  I am using ffmpeg to play an RTSP stream. I have a loop like

      while (av_read_frame(formatContext, packet)>=0)
  
      {
  
        doWork();
  
      }

  I can watch the stream as long as there is something moving in front of the camera. But whenever the view is stable the above function returns EOF as I checked with av_strerror. Any ideas why and how to fix it ?

  thanks

• how to publish flv file using ffmpeg to RTMP server in `real time` ?

  29 octobre 2012, par Akram Berkawy

  what i'm trying to do is publishing a .flv media file to RTMP server to let subscribers watch it.
  i'm testing to view the stream in several subscribers (the oflaDemo) and with ffplay.

  the problem is that ffmpeg publish the 5 minutes .flv file to the server in nearly 20 seconds, in these 20 seconds the stream appear on subscribes, but after that it cuts.
  the command i use is :

  ffmpeg -i file.flv -re -acodec copy -vcodec copy -f flv "rtmp://localhost/oflaDemo/aaa live=1"

  how can i force ffmpeg to stream the 5 minutes file in 5 minutes, or any other solution.

  thanks.

• Recapping WebM’s First Week

  25 mai 2010, par noreply@blogger.com (John Luther) — webm, vp8, vorbis

  The WebM project launched last Wednesday with broad industry backing (watch video of the announcement). The list of supporters keeps growing with new additions such as the popular VLC media player, Miro Video Converter, HeyWatch cloud encoding platform, and videantis programmable processor platform. We’re also happy to see that future versions of IE will support playback of VP8 when the user has installed the codec.

  Our announcement sparked discussions in the community around the design and quality of our developer release. We’ve done extensive testing of VP8 and know that the codec can match or exceed the quality of other leading codecs. Starting this week, the engineers behind WebM will post frequently to this blog with details on how to make optimal use of its VP8 video codec and Vorbis audio codec. We are confident that the open development model will bring additional improvements that will further optimize WebM. In fact, the power of open development is already visible, with developers submitting patches and the folks at Flumotion enabling live streaming support in their product just three days after the project was launched.

  Keep an eye on this blog for regular updates on the adoption and development of WebM. To participate in the conversation or to ask questions of the WebM team, please join our discussion group.
