Re: jpegli - new and clever jpeg encoder

After the plugin installed i restarted XnView MP x64 and then there is "JPG Guetzli JPEG" as option under Save As.

Re: jpegli - new and clever jpeg encoder

Guetzli can't do anything but 1x1,1x1,1x1. If the ouput is different it isn't a guetzli file.

Re: jpegli - new and clever jpeg encoder

When we are at it.
Saving a jpg file as "JPG - Guetzli" in XnView MP uses the long time the guetzli encoder needs but saves a different file. Guetzli has always sub-sampling 1x1,1x1,1x1 but when i just tried it creates a sub-sampling 2x2,1x1,1x1 file with the size of the default jpg encoder.

Re: jpegli - new and clever jpeg encoder

In libjxl v0.10.2 is a cjpegli.exe that produces 100% valid jpg files. https://github.com/libjxl/libjxl/releases/tag/v0.10.2 The only reason why the produced files may be incompatible is it creates progressive files by default. Already a year back at an early stage jpegli tested very well and now on...

jpegli - new and clever jpeg encoder

There is a new king in town! jpegli does really well and shows jpeg ain't dead yet. It is fast also. https://github.com/libjxl/libjxl/tree/main/lib/jpegli Visual comparisons imho show jpegli more robust and efficient as guetzli and miles ahead of mozjpeg quality. Unfortunately Xnview/imagemagick qua...

Re: XnviewMP starting very slow

The first start of MP takes 3 seconds once a day since i use Win 11. After that it starts immediately. On Win 10 it was fine.

Re: Please add additional JPEG encoders like MozJPEG and Guetzli!

It may be worth to add the latest Guetzli from Git. It works better here with files that had no good compression before maybe because of code optimizing and a new Butteraugli.

Re: 0.87: XnView MP crashes when saving as Guetzli JPEG

Interesting that this was it. It shouldn't crash ending the process with simply hitting ESC imho. I'd suggest to not use guetzli at this point. It seems to reduce quality to much when used in MP. Have a look here: https://newsgroup.xnview.com/viewtopic.php?f=62&t=36099#p144737 I suggest some extra s...

Re: 0.87: XnView MP crashes when saving as Guetzli JPEG

It may simply not done with processing. guetzli needs lots of processing time. 2-3 minutes is normal even for small 2 megapixel pics here with a 4.4GHz machine.

To my suggestion above i saw guetzli itself will add an "--preserve-exif" option. https://github.com/google/guetzli/pull/175

Re: 0.87 beta 3 - Batch conversion - jpeg guetzli encoder settings

I used some cmd also. Lately a simple frontend popped up here http://www.multipetros.gr/public-projec ... /guietzli/
Having it working correctly in the MP batch conversion like your thread here asks for will be much better!

Re: 0.87 beta 3 - Batch conversion - jpeg guetzli encoder settings

Guetzli is meant to produce HQ jpg from png so i don't know why to argue. I need jpg in the end result. No compiled exe of the OpenCL version around so far i guess. The chinese coders may have a .cn page i don't know about You may misunderstand the problem. When i want to shrink existing pngs MP doe...

Re: 0.87 beta 3 - Batch conversion - jpeg guetzli encoder settings

Hello forum! I enjoy Xnview for many years now and i once recommended to license original Xnview for a medium big company here in germany. Now i tested MP for the first time and like the idea it integrates the google Guetzli encoder. I think the internal workflow is a bit strange. When i encode a pn...
