Unsolicited IO from library code #8

Closed xandkar closed 3 months ago

xandkar commented 3 months ago

I upgraded to 1.2.1 and it fixed this problem. Now I upgraded to 1.2.4 and the problem is back, albeit in different places, but there're still spurious print statements on errors.

These should either be log statements (ideally with tracing) or not be present at all, since this is a library being called by apps with different expectations about IO.

I'll be happy to do the work of converting them to tracing calls if you're OK with it.

Thank you very much for your suggestion. Changing the print/eprint to tracing is a great suggestion. If you are willing, your PR is very welcome! Thanks!

@xandkar Before modifying the code, make sure you have pulled down the latest main branch code to prevent conflicts. Because I made some bug fixes, as well as some small internal improvements, thank you!

mindeng commented 3 months ago

@xandkar Can you post these printouts? I want to see what went wrong. It would be better if you could attach the files where the parsing failed. Thank you!

I often see stuff like this for videos:

box size of box 'mdat' is too big: 156013308
box size of box 'mdat' is too big: 107592213
box size of box '****' is too big: 440786851
box size of box '****' is too big: 440786851

I'll try to find/make something I don't mind sharing publicly :)

Hi @mindeng,

Here're a couple of video files which result in errors (one webm - made by Cheese, and one mov - made by an iPhone SE).

Error texts are in ${video_file_name}.txt

Got! I'll find time to look into it, thank you!

Hi @xandkar !

webm is already supported! It also supports mkv, mka and other files.

However, this version has undergone major changes. I have rethought the API design, introduced new, more ergonomic APIs and usage methods, and also optimized performance (especially for batch file processing scenarios). Therefore, the release of this version may be slightly later.

If you have other file types that need support, please feel free to let me know, thank you!
