• How to convert a video to be compatible with facebook graph (reel) api

  25 mai 2023, par Micha

  I am currently trying to get this api to work : create user media

  


  Everything works if I try to post photos. But as soon as I try to post a reel I always get the same error :

  


  {&#xA;  "error": {&#xA;    "message": "The video file you selected is in a format that we don&#x27;t support.",&#xA;    "type": "OAuthException",&#xA;    "code": 352,&#xA;    "error_subcode": 2207026,&#xA;    "is_transient": false,&#xA;    "error_user_title": "Unsupported format",&#xA;    "error_user_msg": "The video format is not supported. Please check spec for supported streams format",&#xA;   "fbtrace_id": "<removed>"&#xA;  }&#xA;} &#xA;</removed>

  


  So I look into the reel specifications here : reel specification

  


  Try as I might, I cannot get it to work. I work with technical google searches all day long, yet this time I seem to be looking in a completely wrong direction.

  


  I have tried converters like Any Video Converter.

  


  I have tried ffmpeg with the following command : ffmpeg -i input.mp4 -c:v libx264 -aspect 16:9 -crf 18 -vf "scale=iw*min(1280/iw\,720/ih):ih*min(1280/iw\,720/ih),pad=1280:720:(1280-iw)/2:(720-ih)/2" -fpsmax 60 -preset ultrafast -c:a aac -b:a 128k -ac 1 -pix_fmt yuv420p -movflags +faststart -t 59 -y output.mp4

  


  If there is a solution with ffmpeg I would appreciate it as I could automate much of the process. But if you know of any converter software I would gladly take that as well.

  


  I think the main problem is the container requirement MPEG-4 Part 14. I can't seem to find any software that is able to produce a video with the required format. The closest I have gotten is MPEG-4 Part 10 but that doesn't work with the api.

  


  Any help would be greatly appreciated.

  


• Why mp4 can not shared on Facebook or Instagram on Android ?

  8 janvier 2023, par János

  This is the file : https://t44-post-cover.s3.eu-central-1.amazonaws.com/2e3s.mp4

  


  When I download and try share, it fails. Why ? This is the parameters was rendered. Downloading and sharing works from iPhone to Facebook on Messenger or Instagram, but not from Android phone to Facebook on Messenger or Instagram.

  


  What parameters ffpmpeg need to be able to share mp4 from Android to Facebook / Instagram ?

  


  await new Promise<void>((resolve, reject) => {&#xA;        ffmpeg()&#xA;            .setFfmpegPath(pathToFfmpeg)&#xA;            .input(`/tmp/input_${imgId}.gif`)&#xA;            .inputFormat(&#x27;gif&#x27;)&#xA;            .inputFPS(30)&#xA;            .input(&#x27;anullsrc&#x27;)&#xA;            .inputFormat(&#x27;lavfi&#x27;)&#xA;            .audioCodec(&#x27;aac&#x27;)&#xA;            .audioChannels(2)&#xA;            .audioFilters([&#x27;apad&#x27;])&#xA;            .videoCodec(&#x27;libx264&#x27;)&#xA;            .videoBitrate(1000)&#xA;            .videoFilters([&#xA;                &#x27;tpad=stop_mode=clone:stop_duration=2&#x27;,&#xA;                &#x27;scale=trunc(iw/2)*2:trunc(ih/2)*2:flags=lanczos,split[s0][s1];[s0]palettegen[p];[s1][p]paletteuse&#x27;,&#xA;            ])&#xA;            .fps(30)&#xA;            .duration(5)&#xA;            .format(&#x27;mp4&#x27;)&#xA;            .outputOptions([&#xA;                &#x27;-pix_fmt yuvj420p&#x27;,&#xA;                &#x27;-profile:v baseline&#x27;,&#xA;                &#x27;-level 3.0&#x27;,&#xA;                &#x27;-crf 17&#x27;,&#xA;                &#x27;-movflags &#x2B;faststart&#x27;,&#xA;                &#x27;-movflags frag_keyframe&#x2B;empty_moov&#x27;,&#xA;            ])&#xA;            .output(`/tmp/output_${imgId}.mp4`)&#xA;            .on(&#x27;end&#x27;, () => {&#xA;                console.log(&#x27;MP4 video generated&#x27;)&#xA;                resolve()&#xA;            })&#xA;            .on(&#x27;error&#x27;, (e) => {&#xA;                console.log(e)&#xA;                reject()&#xA;            })&#xA;            .run()&#xA;    })&#xA;</void>

  


• 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)
