• Laravel ffmpeg failed to execute command

  4 septembre 2022, par John smith

  I'm using protonemedia/laravel-ffmpeg package everything works fine on localhost but on the live server, there is an error message shown.

  


  ProtoneMedia\ LaravelFFMpeg\ Exporters\ EncodingException

        $this->video->update([
            'converted_for_streaming_at' => Carbon::now(),
        ]);
    }
}


  


  I'm storing the key at custom disk "streamable_keys", and converted videos should be stored in "streamable_videos".

  


  the streamable keys are generated and saved to a directory without any issues, but streamable videos are not saved to the directory.

  


  after some tracks I found that the problem happens in this line of code :

  


          ->save($this->video->id . '.m3u8');


  


  all the lines before that line work perfectly.

  


  any ideas on how to fix that ?

• How to Combine two Live Streams(mjpeg + pcm) for ffmpeg or ffplay playback ?

  7 septembre 2022, par sharimken

  What's the correct command to combine two live streams (mjpeg + pcm) for playback ?
Currently, I have to playback them separately via ffplay. Is it possible to combine them as one for playback ?

  


  //video stream mjpeg
ffplay "udp://127.0.0.1:3001"

//audio stream raw pcm
ffplay -f s16le -ac 1 -ar 11025 "udp://127.0.0.1:3002"


  


  I found some example commands suggested by others, but not sure how to implement for my above use case. https://superuser.com/questions/1410764/how-to-play-two-remote-streams-simultaneously

  


  ffmpeg -headers X -i .. -headers Y -i .. -c copy -f nut - | ffplay -f nut -i -


  


  Edit 2022/09/07 :

  


  Thanks for @kesh suggestion, below script works for first 1 second with video and sound.

  


  ffmpeg -i "udp://127.0.0.1:3001" \
-f s16le -ac 1 -ar 11025 -i "udp://127.0.0.1:3002" \
-c copy -f nut - | ffplay -f nut -i -


  


  However, sound was muted after first error occured.

  


  udp://127.0.0.1:3001: Input/output error


  


  Updates :
Above issue has been solved, with below commands :

  


  ffmpeg -i "udp://127.0.0.1:3001?overrun_nonfatal=1&fifo_size=100000" \
-f s16le -ac 1 -ar 11025 -i "udp://127.0.0.1:3002?overrun_nonfatal=1&fifo_size=100000" \
-c copy -f nut - | ffplay -f nut -i -


  


  However, if the mjpeg stream is paused or skipped few frames, the audio will stop too. It's not necessary to sync them, and how to keep the audio stream playing as long as it receives data ?

  


  Q1 : the default video fps is 25, can I set it to 30 or 60 ?

  


  Q2 : pcm data stream is consistence, but mjpeg is not consistence. audio stream will stop once mjpeg is paused/resumed. What's the best solution ?
