• Raspberry Pi Youtube Stream with ffmpeg : libx264 unknown

  21 juillet 2016, par tm011036

  I want to use my raspberry pi 3 for a youtube stream via an usb camera. Therefore, I compiled and installed the following tools :

  ffmpeg, libx264, libav-tools

  However, when running the following code i always get an error that the libx264 encoder is unknown :

  ffmpeg -f v4l2 -framerate 25 -video_size 640x480 -i /dev/video0 
  
  -codec:v libx264 -b:v 700k -maxrate 700k -bufsize 700k -an -f 
  
  flv rtmp://a.rtmp.youtube.com/live2/MYYOUTUBECODE

  I installed x264 via clone and make install using this guideline. How can I check if this encoder was installed correctly ? I am already stuck for 2 days on this problem - please help !

  Related hints (e.g. libavcodec-extra codec, type errors) regarding this problem unfortunately also didn’t help further.

  Thank You.

  The entire console output is :

• Raspberry pi live stream to youtube stopped working

  27 décembre 2023, par Gergely Maros

  I have a working setup for streaming a video to youtube with my raspberry pi 3.
It was work until yesterday. Nothing changed but I have an error when I try to start the stream.
Running the following command :

  



  raspivid -o - -t 0 -w 1280 -h 720 -p -hf -fps 25 -b 2560000 | avconv -re -ar 44100 -ac 2 -acodec pcm_s16le -f s16le -ac 2 -i /dev/zero -f h264 -i - -vcodec copy -acodec aac -ab 128k -g 50 -strict experimental -f flv rtmp://a.rtmp.youtube.com/live2/my_key


  



  And get this error :

  It worked more over a month, but now (I don't know why) stopped working.

  



  Can anyone help me ?

  



  Cheers,
