• Alternatives to Facebook 360 Encoder for Spatial + Headlock Encoding ?

  31 juillet 2023, par Robert N

  Unfortunately FB 360 Encoder is no longer being worked on with no alternatives that I can find & right now I cannot get it to work on mac.

  


  I am looking to combine two stems as per the tutorial here - 1 spatial audio (16channel) with 1 headlock audio (stereo) for a 180 stereo (side by side) video in the highest quality allowed for a Meta Quest 2 headset.

  


  FFMPEG recipes are preferred but paid alternatives are welcome. So far the best I could find for encoding was "use the old software" but even if it worked, I do not trust out of date/dead software for production : Facebook 360 Encoder Error - FFmpeg libavdevice.57.dylib (not a mach-o file)

  


• FFMpeg : How to stream to Facebook Live ? [closed]

  22 mars 2024, par Thomas Carlton

  I have ffmpeg on Windows.

  


  I would like to stream an mp4 file to Facebook Live. The video has an audio track.

  


  I am running the following command :

  


      ffmpeg 
    -re -i video.mp4 
    -acodec libmp3lame 
    -b:a 128k 
    -pix_fmt yuv420p 
    -profile:v baseline 
    -bufsize 6000k 
    -maxrate 1500k 
    -deinterlace 
    -vcodec libx264 
    -preset veryfast 
    -g 30 
    -r 30 
    -f flv 
    -flvflags no_duration_filesize 
    "rtmps://live-api-s.facebook.com:443/rtmp/mykey"


  


  This command works for exactly 14 frames and then it stops.

  


  

  


  Then, I'm getting the following error saying "Conversion failed".

  


  

  


  I tried to stream to AWS IVS. But I'm getting the exact same error.

  


  What is wrong with my command ?

  


• avio_open2 fails randomly for RTMPS Facebook live streaming

  3 janvier, par Usama

  I am trying to re stream a video to Facebook RTMPS endpoint and , facing an issue specifically with Facebook's RTMPS endpoint . I have tried with linkedin RTMPS endpoint and its working fine , but Facebook end point some times works and fails some times its totally random . The avio_open2 call sometimes fails randomly, returning a -5 error. This only seems to happen with the Facebook endpoint .on ffmpeg log side I see that the handshake was successful , I don't understand the reason for failure here. (i am running in multithreaded environment )

  


  int ret = avformat.avio_open2(pb, url , AVIO_FLAG_WRITE, null, getOptionDictionary()) ;
