  • 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>

    &#xA;

    So I look into the reel specifications here : reel specification

    &#xA;

    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.

    &#xA;

    I have tried converters like Any Video Converter.

    &#xA;

    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 &#x2B;faststart -t 59 -y output.mp4

    &#xA;

    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.

    &#xA;

    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.

    &#xA;

    Any help would be greatly appreciated.

  • Libav multi-threaded decoding

    7 mars 2021, par Amir Mirmoeini

    According to the documentation here, Libav provides the "infrastructure" for multithreaded decoding. But the docs are vague and confusing regarding how multithreaded decoding is implemented. Is it internally supported and just requires setting a flag in the struct, or does the user have to provide his own implementation with the provided functions ? I searched a lot but could not find even one example of multithreaded video decoding with libav.

  • Transcode video using the output format of another video in ffmpeg [closed]

    8 février 2013, par Nick

    I would like to convert videos to the same format as an arbitrary file. This format is not fixed. This "template" file should not be modified.

    Rather than setting the command line options manually each time, is there a way to specify one video as the input, another video as the output format, and then output all that to another file ?

    I don't see anything in the docs about this, but maybe I'm searching using the wrong terms. I'm using OS X, but can use any of the GNU tools as well.
