• Unable play Audio AC3 in Exoplayer + FFmpeg, i read the guide correctly, should I be wrong ?

  24 mars 2020, par mOsCpU0

  I would like to implement FFmpeg in Exoplayer in my App, in order to read video formats with AC3 Audio track.

  I followed these steps, but I still don’t hear Audio AC3 and I can’t enable Exoplayer to play the audio track via Software.

  I have my code if needed and the guide I used is this :

  https://github.com/google/ExoPlayer/tree/release-v2/extensions/ffmpeg

  I hope for your help !

• We're Creating a New AI tool and Got Stuck on This 1 Step [closed]

  22 février 2024, par Daniel

  Thanks for helping with this question,

  


  Anybody who knows PHP, React js, FFmpeg, or Open AI API can help here :

  


  We are currently creating a tool with PHP laravel and React JS. It lets normal creators input a simple text prompt and they'll get a fully original short (30 video fast-paced video) for their channel. But we have an output problem :

  


  

  • On the output of the videos, there's supposed to be AI generated images that have cool animations in order to make everything more fast paced. But our developers are making animations that are super slow and not dynamic or interesting enough. What open source library/tech could we use to create stunning animations and more action ?! Any suggestions would help here,

  


  


  ---

  


  We are currently using an FFmpeg to create a video automatically for our users. The videos consists of [images, captions, voiceover, background music, and animations) all generated by our AI tool and put together.

  


  Here's what we want as a video (dynamic, fast paced, and many animations) : https://drive.google.com/file/d/1ONCczJh_Uk9m6oRDPGFQYjJPWUhy8hdV/view?usp=sharing

  


  Here's what we're getting : https://drive.google.com/file/d/1sMKGB88ouTHsEdahc0Zyt8rKEvZWhTco/view?usp=sharing

  


  Thanks for any help here.
