Google AppEngine flex as a transcoder [closed]
6 septembre 2021, par jACKSituation :


- 

- A Nodejs/Express application running on appengine flex.
- Using FFmpeg to cut videos, and merge different types of videos. 1080p 30fps videos, merged video duration usually around 8 hours.
- Need for a massive amout of processing power for those edits.
- The express server needs to be reachable 24/7 & flex is incredibly expensive if run on a 24/7 basis.










Goal :


- 

- To have a cost efficient ffmpeg transcoder on a private enviroment =>
- Flex instance as a maximum spec, but as its idle reduce the price significantly.






Or is this a situation where a redesign is imminent ? eg. Compute Engine


Tried approach


- 

- B8 Standard instance => Since the payload is pretty big, its causing the B8 instance to crash.




Thanks.

My Colab uses Python 3.7.15 and ffmpeg/ffprobe version N-109226-g2ad199ae31-20221125 (from https://github.com/BtbN/FFmpeg-Builds).


I tried searching similar issues as mine here, but most of the solutions are way beyond my knowledge, I'm not sure how to apply them to my use case.


I'll appreciate your help, thank you !
