• Facebook Graph API - Getting error 2207026 when trying to upload video

  22 novembre 2022, par NiVeK92

  I try to upload a video via the graph API but as the title states, I get an error that states that I use an unsupported video format.

  


  I thought maybe the original video file doesn't match the video specifications as defined on https://developers.facebook.com/docs/instagram-api/reference/ig-user/media#video-specifications so I wrote a function to convert the file to match the specification, using ffmpeg with the following command (I tried many different ones, but this is the last one I tried)

  


  ffmpeg -i ${tmpInFile} -vf format=yuv420p -vf scale=-2:720 -pix_fmt yuv420p -r 30 -movflags +faststart -c:v libx264 -b:v 3M -c:a aac -b:a 128k -ac 2 -ar 44100 -shortest -f mp4 ${tmpOutFile}

  


  Unfortunately, the error persists.

  


  Here's the complete process :

  


  First I use await fetch('/api/convert-mp4', { method: 'POST', body: file }); to send the uploaded video file to the backend.

  


  Next I get the blob data from the request with const blob = await request.blob();.

  


  Then I create a temporary file with await fs.writeFile(tmpInFile, await blob.stream()).

  


  Then I call ffmpeg with the above command mentioned above and then read the file with const buffer = await fs.readFile(tmpOutFile);.

  


  Then I send the buffer as response body back to the client with return {status: 200,body: buffer}.

  


  Then I get the blob data from the response with const blob = await convertVideoResponse.blob();.

  


  Finally I convert it back into a file object with
const convertedFile = new File([blob], file.name, { type: 'video/mp4' });

  


  This file I upload to Supabase Storage (https://supabase.com/storage), and get a publicly accessible url (which I confirmed by opening it in an incognito tab).

  


  In the supabase dashboard I can see the video file has the correct media container (video/mp4) and the file size is small enough.

  


  Does anyone have an idea what could be the issue ?

  


  Edit :

  


  By changing the ffmpeg command to use h265 instead of h254 ffmpeg -i ${tmpInFile} -vf format=yuv420p -vf scale=-2:1350 -pix_fmt yuv420p -r 30 -movflags +faststart -c:v libx265 -vtag hvc1 -an -x265-params crf=25 -b:v 3M -c:a copy -c:a aac -b:a 128k -ac 2 -ar 44100 -shortest -f mp4 ${tmpOutFile} I managed to get it to work for some videos but not all, which confuses me, as I assumed that the video attributes should be the same for all videos processed by the same command.

• Triggering live stream on facebook using Node.js

  27 décembre 2017, par Ricky

  I am trying to find a way to be able to start a live stream using node.js where I take in an hls source and output rtmp onto facebook using ffmpeg.

  The goal is to do this without actually going to facebook itself, doing all of this on node :

  -take an hls source
   convert source video and audio and add video filters
   create a live stream post on facebook
   output converted video onto said livestream

  Any ideas on how I could do this ?
