• Packaging AV streams from youtube into mpeg2 ts container ?

  20 novembre 2015, par user3309374

  I am trying to pull video streams from Youtube and repackage it into MPEG2 TS container.Youtube streams audio(.m4a) and video(.mp4) as separate streams and packages into mp4 container format at the client end.Are there any ffmpeg libraries or any tools which packages the individual streams into MPEG2-TS container ?

• How to merge 2 streams and send the stream to youtube ?

  22 janvier 2021, par Nikhil Jacob

  Trying to merge 2 rtmp url from one youtube account and sending the merged stream to another youtube account

  


  Details :

  


  


  1. We enabled 2 youtube account with Go Live feature

     


  


  2. Used the larix Broadcaster mobile application to send the stream to the first youtube account

     


  


  3. This worked fine and we were able to see the stream on youtube

     


  


  4. We brought up the other youtube account and captured it's rtmp url

     


  


  5. We used the following command to take the stream broadcasted on the first account to stream to the other youtube account

     


     ffmpeg -re -i rtmp ://a.rtmp.youtube.com/live2/StreamKey 1 -i rtmp ://a.rtmp.youtube.com/live2/Stream Key1 -strict -2 -f flv rtmp ://a.rtmp.youtube.com/live2/Stream Key 2

     


  


  


  However, we are getting a response server validation failed on

  Please clarify why the merging of 2 rtmp url is failing. Should we setup our own rtmp server to capture the input stream and then send the output stream to youtube ?

  I am trying to stream to youtube but the stream health says no data.

  but as far as youtube, no data is being sent over.

  


  What is causing this to fail ?
