• The YouTube live stream encountered a failure

  12 février 2024, par kuldeep chopra

  We are currently utilizing the ffmpeg library for streaming on YouTube Live. However, we have faced issues in a recent live streaming session that initially functioned correctly but encountered errors around the 13 to 15-minute mark. The error logs from FFmpeg during this session are as follows :

  


  Live Stream 1 Error :(Attempt 1)

  


  


  ffmpeg [flv @ 0x555c4bdfe680] Failed to update header with correct

  Live Stream 2 Error (Attempt 2) :

  


  


  Slave muxer #1 failed : Connection reset by peer, continuing with 1/2

  It is crucial to note that we have conducted numerous live streams on YouTube without encountering this error previously ; this is the first instance of such an issue.

  


  We kindly request your assistance in investigating and providing insights into the underlying problem causing these error messages. Any guidance or support you can offer in resolving this issue would be greatly appreciated.

  


• Saving video to SD card while live streaming to YouTube using FFmpeg

  15 mai 2020, par Zohair Ul Hasan

  I'm trying to set up a Raspberry Pi so that it live streams video to YouTube using the Raspberry Pi camera and also saves the video to the SD Card for backup, in case the internet gets disconnected. I used Alex Ellis's guide to set it up, which is basically a docker image that anyone can download and set it up. He sets up the live stream to YouTube but doesn't save the video offline.

  



  So, I tinkered with his code and found that he used FFmpeg to stream to YouTube. The following line is basically the heart of his method to stream :

  



  raspivid -o - -t 0 -w 1920 -h 1080 -fps 40 -b 8000000 -g 40 | ffmpeg -re -ar 44100 -ac 2 -acodec pcm_s16le -f s16le -ac 2 -i /dev/zero -f h264 -i pipe:0 -c:v copy -c:a aac -ab 128k -g 40 -strict experimental -f flv -r 30 rtmp://a.rtmp.youtube.com/live2/$1


  



  I read up about FFmpeg and apparently, to save this stream to my SD card all I need to do is add the directory where I want to save my video to the end of this code. I modified it like so at the end of the line :

  



  raspivid -o - -t 0 -w 1920 -h 1080 -fps 40 -b 8000000 -g 40 | ffmpeg -re -ar 44100 -ac 2 -acodec pcm_s16le -f s16le -ac 2 -i /dev/zero -f h264 -i pipe:0 -c:v copy -c:a aac -ab 128k -g 40 -strict experimental -f flv -r 30 rtmp://a.rtmp.youtube.com/live2/$1 /home/pi/Desktop/my_video.mp4


  



  However, when I ran this, the terminal threw this error :

  



  /home/pi/Desktop/my_video.mp4: No such file or directory


  



  This path, however, definitely exists by default in all Raspberry Pi's. I'm not sure what's wrong here, can someone please help me out ?

  



  P.S : as an additional side question, I read up the documentation on FFmpeg and it specifically says not to use the -re argument when using a live input source, but Alex uses it anyways. Should I substitute it with something different ? It works fine right now though.
