XnView Software

Thanks for update! So, we can say that multi-image AVIF is still in "to be fixed" state, right?

the fix was to display correctly the first frame. Currently there are problems to get others frames with libheif

Has it something to do with issue 377 / issue 1371 ?
Why cannot you use libavif ...

I'd like to bump this, as they're mostly just checkboxes that lead to an extra parameter internally.

And one other thing:
* Allow RGB as an output colorspace, to guarantee fully lossless end-to-end, otherwise the conversion to/from YUV introduces some errors even at 4:4:4.

I guess I accidentally ...

I checked, and ultimately Phoenix uses CGImageSourceCreateWithData, the main MacOS image decoding API, which is very optimized and GPU accelerated. While XnView normally only uses built-in code, it's not impossible that it could interface with MacOS's API... just doesn't seem likely, especially ...

I can confirm that hif files show up in the browser just fine and in explorer as being registered to XnView, without having to add it anywhere in the custom filter.

Whatever's posted on the site shouldn't be considered the absolute last word, it's just a minor site bug report.

There are a handful of things missing from the AVIF settings panel that might be useful, for those who might want to use them:

* Lossless: Since the format supports it anyway.
* Auto/8/10-bit output, instead of just 8: Even with 8-bit input, forced 10 bit output is sometimes dramatically better ...

The AVIF panel has four options: Format, speed, min/max quant, min/max alpha quant.

I think you kind of forgot the actual target quant, the main and most important setting. It would be like not having quality on the JPEG export. The min/max are rather advanced settings most people won't need to ...

I guess I'll try to see if there's any way to reproduce it, then, and check in a libheif fix if it's a new bug.

Did you guys do any kind of triage or get crash logs on this? I might be able to track it down and fix it if I can see what might've happened. The odd thing is that 1.16 hasn't really introduced changes in the threading behavior, so I'm curious why one works and the other didn't.

This problem is supposed to be fixed in XnView MP 0.98.1 . Please check and confirm the bug fix here.


My system is Windows 10 version 20H2, scaling is 125%, image samples below:

Is this just completely forgotten, or is it tracked anywhere (classic and/or MP)? Having to drop into Photoshop just to copy or move a selection something anywhere but the top right corner is a little much...

FWIW, xnview integrates both libavif and libheif, and imho libheif is now better at decoding (and encoding) avif than libavif, so there might not be a reason to keep both. One of the nice things about the format being exactly the same, swapping out the compressor and calling it another format is ...

I have a video that consistently deadlocks the background thread that creates thumbnails; while things in the same folder can still be opened, any attempt to change the folder or close XnView will completely hang the whole program. (This was me earlier this evening.) 0.93.1 x64 on Windows 10 1903.

I searched but I can't find a bug open about this. If XnView Win64 has been open for a while, which seems to be at least a few hours, but sometimes I have it open for weeks at a time, it can't import the clipboard anymore. It just doesn't show lit up as an option in the menu, nothing happens if I ...

In Windows, video is via DirectShow. Unfortunately, that API generally holds exclusively open any video with an open handle, since it's always required to be ready to render the next frame without crashing. It's probably best to just assume that video won't work like images on Windows, and go from ...

Microsoft does explicitly say that runtime dlls should never be distributed by the app anymore, and the generic Visual Studio runtime installer should be used instead. Otherwise you risk local security problems in the version that was installed (if you can even get it to run; the new registration ...
