• FFmpeg v0.12 is not working for Angular 16

  30 septembre 2024, par Amrut Kumar

  Currently, I have tried integrating ffmpeg v0.12 for my angular 16 project. But it takes forever for the ffmpeg to load. It goes into infinite loop. My guess is that its unable to load the worker script due to incompatibility with Angular 16 dependencies and functionalities.
I have tried ffmpeg v0.12 in my angular 18 app and everything is working just fine. The same changes wont work for my angular 16 application.
To take a step further, I have downgraded ffmpeg version to 0.11 and its now working perfectly fine for my angular 16 app.
Have any of you faced similar issue as I have explained above ? If yes, what steps did you take to resolve it ?

  


  I tried loading ffmpeg v0.12 with angular 16 app and I was expecting it to load just fine as I was able to achieve this with angular 18 with totally similar code changes.
