I don't really know Cython, but I fumbled a change that seems to work. Until code is updated here, this might serve as a guide for those encountering the same...

I suppose a possibility is when you don't trust the detected colorspace to be accurate. libavcodec does support the idea of an 'unknown' colorspace, so being able to explicitly override...

I recall looking into this a while ago, so my memory may be a bit sketchy, but something I noticed. For whatever reason, PIL [implements its own PNG filtering](https://github.com/python-pillow/Pillow/blob/22d797fd81d444fef3d907f4a5913623736db63d/src/libImaging/ZipEncode.c#L172) (as...

May have spoke too soon in my previous comment. Considering how long PNG has been around, I thought that the popular libraries would be reasonably well optimised, however, looking into...

Thanks for looking into it. If you set compression level to 0, is that still where most of the time is spent?

That indeed is very surprising. Would be interesting to know what it's spending all its time on, even when it's doing no compression.

Interesting idea - I'm not sure it'd help for many of the settings, but there might be something for some of them. I'll need to think about it. Thanks for...

Thanks for reporting your results and the bug. The latter should be fixed in the latest code. I'll continue looking at exposing more detailed info.

Thanks for the suggestion! This is an interesting idea, probably a bit tricky to implement though (has to be tied to a build). There's also the question of dependencies, which...

Ah I see, missed that - thanks for pointing that out! It looks like there's some post-build step (alter executable's CRC) that the author performs before release, because building par2j...
