r30040: Error loading OpenGL support: 'JPEG'

However, "yeah, you are right", Intel is graylisted:

Haha, that's not a very useful message!

Can you please run it in debug mode? Either adding -d opengl or just running Xpra_cmd opengl.
(I don't have an opengl enabled system at hand to reproduce this)

[stdedos]

-d opengl is required

KeyError: 'JPEG' is because of #3133, somewhat similar to #3139.
The packaged version of xpra doesn't have the ability to save (and load?) jpeg...
Either because the trimming done in #3133 was too aggressive or because python-pillow changed the dependencies.

Will fix ASAP.

[totaam]

The commit above should avoid failing opengl just because pillow is not packaged properly.
Sure enough, I can see that jpeg is missing - which will help me fix things - running Encoding_info.exe -v:

* enc_pillow           : lib\xpra\codecs\pillow\encoder.pyc
                         encodings: png, png/L, png/P, webp
                         encodings = ['png', 'png/L', 'png/P', 'webp']

[totaam]

r30054 works-for-me(tm): jpeg shows up in enc_pillow and I've simulated errors to trigger the png fallback code path.

[stdedos]

Verified as fixed here too 🙂

Side question: Awesome move to move the logs to their respective display folders! When did you do that? 😀
