  • Facebook Live Stream API on iOS

    11 août 2020, par Deepak Sharma

    I see Facebook has a graph API to go live on Facebook, fetch all user reactions, create a poll, etc. But I don't see any sample code in the SDK for the same. I want to stream video from iOS/Android app to Facebook.

    


      


    1. Is it sufficient to use ffmpeg based libraries on iOS to create live RTMPS stream on Facebook or a third party cloud service is required ? Any sample code that has the Facebook live function builtin ?

      


      2. 


    2. What does the live video API review involves ? Anyone familiar with common causes of rejection for the live video API ?

  • Facebook live video can only be previewed while streaming my Mac screen

    24 janvier 2017, par iownthegame

    I use the following ffmpeg command to share my screen streaming to Facebook.

    enter image description here

    ffmpeg -f avfoundation -r 10 -video_size 352x288 -i "0" -c:v h264 -f flv 
    
"rtmp://rtmp-api.facebook.com:80/rtmp/1269140699772419?ds=1&a=AaYsXcYcdHQrrrUF"

    then I can see the video preview scenes
    enter image description here

    however, once I press the ’Go Live’ button, and go to my facebook page, I can find a post said I am Live Now. When I press the ’play button’, there are only black scenes that last for 1 2 seconds, and the video ends.

    enter image description here

    And there is also a weird thing, the video can be played when I end up the live stream. When refreshing the page, I can find a post said I was Live, the video of this post can be played successfully.

    Anyone knows why the video can be watched when previewing and finishing live but not the exact live moment ?

    [updated]

    During the live streaming period, if I press the play button, there are only 1 2 seconds black scenes and the live stream ends.
    enter image description here

    However if I press the video frame again, another modal pops up then I can see the live streaming. Is it a facebook bug ?

  • 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.

    &#xA;
