• Ffmpeg live streaming to Youtube - "Connect streaming software to start preview"

  10 septembre 2019, par Zoltan Fedor

  I have an rtsp feed (H.265) which I am trying to stream to YouTube Live, but whatever I do YouTube Studio just showing the waiting icon with "Connect streaming software to start preview".

  .sh file for streaming :

  VBR="1000k"
  
  FPS="30"
  
  QUAL="ultrafast"
  
  YOUTUBE_URL="rtmp://b.rtmp.youtube.com/live2"

  KEY="xxxx-xxxx-xxxx-xxxx"

  Basically all looks good to me - still, in YouTube Studio only the waiting icon with the "Connect streaming software to start preview" message is visible, not video feed.

  Any ideas ?

  Here are the respected sizes of inputs and output :

  inputImage.jpg : 160kb

  inputAudio.mp3 : 380.3kb

  output1.mp4 : 1.3MB

  The size of output video is pretty large as compared to the input audio. This is my first issue.

  Secondly, as you can see, this process takes 30sec, which is too much I think.

  How do I solve this two problems ?

  • reducing the output video file size

  • reducing the time this process takes.

  I’ve gone through numerous online links, including a lot of questions on this forum for the past several hours but still not able to solve this.
  Tried playing with framerate but disturbs the duration of the output video.

  Can someone please help here. Let me know if any other information is needed.

  1 thing that helped me reduce the size of final video from 3MB to 1.2MB was to compress the image that I am using.

• FFMPEG commands isn't working in Android Q

  Try this command for merge two audio files, but its not working in Android 10.0(Q) while targeting sdk 29.
But, this command is completely working on targeting sdk 24 to 28.

  



  I am using this library of FFMPEG implementation 'nl.bravobit:android-ffmpeg:1.1.7'
