Memory leak #5

Closed onthegit closed 1 year ago

onthegit commented 1 year ago

Hello, thanks for the project. After some testing I noticed that memory is increasing in chrome (without being gced). I suspect it is because releaseUsedSamples is not being called and all the the chunks stay in mp4boxjs. More info here: https://github.com/gpac/mp4box.js/wiki/Memory-managment-in-MP4Box.js

Yeah, it's true that mp4 samples are not being actively released at the moment, and processing larger video files may have memory leak.

I expect to submit the memory optimization code next week.

@onthegit The VRAM overload issue has been resolved and the js heap is currently increasing slowly but not significantly. I will close this issue and if it does not resolve the issue you are experiencing, please reopen the issue and provide the test file.
