Invalid encoding?

Reported by: Mike Owned by: Mike
Priority: major Milestone: 0.14
Component: encodings Version: 0.12.x
Keywords: Cc:

Description (last modified by Antoine Martin)

I get many errors about invalid encoding. Invalid seems to be png and jpeg. But the client/server supports jpeg and png encoding. Why is it invalid?
Also when I use webp or h264 these messages appear.

I'm on trunk r6870, but I've seen this behavior for some weeks now.

Please specify your distro, etc..

Do you have python-pillow installed? (without it, png and jpeg should not be available and the server should not use those encodings - so this looks like a valid bug)

Sorry!, python-pillow was not installed on the client.
After installing dev-python/pillow-2.4.0 it works.

Distro is gentoo.

Thanks for your quick response.

I am re-opening this because until we make pillow mandatory (and maybe we should), the client should work without and should not tell the server to use encodings it cannot handle.

comment:5 Changed 8 years ago by Antoine Martin

This was a bug, fixed in r6904: we can still paint png and jpeg on the client without having PIL installed (though this is not optimal) by using gdk pixbuf.
Problem was that we relied on the PIL codepath... and so we failed.

There is another problem when we start the server without PIL:
