  convert request to begin encoding the video, and status request that retrieves
  * the current encoding status so the progress bar can be updated.

• Test if YouTube stream key is still active

  17 avril 2022, par codingmaster398

  I'm making a service to stream to YouTube, simply put.

  


  If the live stream ends or the stream key is no longer being used, we need to know. So far, it plays a short 3 second clip every once in a while, and if FFMpeg stops before it streams, we assume that the stream key is invalid. However, once we start a stream with the correct stream key, then end it and reset the stream key in another stream, the stream key still is being picked up as active.

  


  Is there any API to see if the stream key is still being used ?
