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

     


  


  


• In Advanced SubStation Alpha (Ass file) how can I animate each word as it is spoken ?

  29 mai 2024, par Nick Powers

  Hello I am trying to get Ass (Advanced SubStation Alpha) code to animate (highlight in green) each word as it is spoken and then have it revert back to white afterwards. What happens with my code is very odd. At first I cannot even see any text. It then appears with multiple lines overlapped, partially hanging off the screen. From this point it "kind of" works. I can see the desired highlighting happening but because the text is all jumbled and overlapping it can hardly be called a success.

  


  In case it is relevant I am using ffmeg to burn in the subtitles. I am using the following command :

  


  ffmpeg -i FortuneTeller1.mp4 -vf "ass=FortuneTeller1.ass" Subtitled.mp4

  


  The resolution of the source video is 1080x1920 (vertical).

  


  My ultimate goal is to burn Hormozi style text with per word animations. I'm far from that so any input would be appreciated ! If you need any additional info/code to help troubleshoot this please let me know what you need and I will provide it.

  


  I have the following Ass code in the Events section :
