and beware that WebM support is not yet complete. More information will be available when holiday season is over in France.

oh ok, I'll try to fiddle with webm, what are the known limitations ?

the problem is: we don't know really. I guess someone has to try and report what is working and what not.
Some already reported of issues.
We have to wait until Nadeo tells us more details.

well, I tried a 128x128 webm that was under 30kB (~25) and it worked !

I used ffmpeg that way to convert it :
ffmpeg -i filename.gif -c:v libvpx -crf 10 -b:v 300K filename.webm

For me crf 10 and b:v 300K were fine, depending on the size, and number of frames, I suppose you'd have to adjut these (and the size, if there are too much frames, 64x64 seems to enough), from livpx encoding options :

By default the CRF value can be from 4–63, and 10 is a good starting point. Lower values mean better quality.

Here, you can choose different values for the bitrate other than 1M, e.g. 500K, but you must set all options (i.e., minrate, maxrate and b:v) to the same value.

That's a great information, thanks for that. I'll add it to the "How-To"-Thread.
