[fixed] bpgdec.exe console flicker

[heimaki]

here's bpg-0.9.7 with both encoders, also xnview "plugin" is included, the above one is garbage because it needs zlib.dll

and no dependencies in bpgenc.exe

and no, you cannot just use the newest x265, it does compile, but the bitdepths other than 8 are missing...

Thanks again, after it compiled so sweetly I didn't bother to try all bitdepths.

[heimaki]

i now also tried the newest jctvc source HM-16.12-4815 but no luck.

i got it comoiling after some small fixes, but bpgenc throws out an error.

no idea what is going wrong, this needs someone with knowledge. it seems the bpgenc code must be modified.

ok, got it working with latest jctvc source HM-16.12-4815.zip
and also x265 2.1 is in there too with bit depth 8 10 and 12 enabled.

not sure if it was worth the effort though. i guess no.

[heimaki]

just in case.

there's a BPG plugin that can even write such files in xnview.

https://github.com/leavinel/BPG-Plugins

works only in x86 versions though.

there's also a x64 version (unofficial) now for this...

It's definitely worth the effort if you share the binary with us - thanks! ...

... and attach the patch from the vanilla bpg source to your version which accepts updates x265/jctvc. You could put a pull request on the bpg site, but I guess development has slowed or ceased so releasing it here and send the bpg author a mail is enough for the time being.

Very nice, thanks. However, there is an issue viewing bpg image with height/width smaller than 128 pixel. Encoding is fine, bpgview.exe show the image perfectly, but XnView crashes. Also, is there no support for 32-bit (image with transparency) encode yet ?

[heimaki]

Hm... for me that works in xnview mp 0.83, even a 50x50px pic opens/saves fine.

what does not work is saving such small files in the x86 version, xnview mp and also classic crashes immediately.

maybe it depends on the settings in the xbpg.ini?
/edit: yes, saving of such fails if i use x265 as the encoder. jctvc does fine.

Also, is there no support for 32-bit (image with transparency) encode yet ?

nope, and maybe never will. the project seems to be abandoned.

https://github.com/leavinel/BPG-Plugins/issues/2

nothing happened since then.

Can you share updated sources?

[helmut]

What is the current status of this? (Topic title says "[Fixed]" but I have the impression that there is still an issue.)

[heimaki]

AFAIK the flickering is fixed.

Good, thank you for your reply, heimaki.

ah, there's a version 0.0.0.4 upcoming.
