Here (currently beta2 release).

XO-4 was supported since alpha2 (a year ago), XO-1.75 since beta1 (March this year).

I didn't build FatdogArm using the OS builder, and the last time I look at OS builder I couldn't find the repository URL there. Admittedly, I didn't look too deeply into it ...

So you're saying that they aren't public? But if they can be pulled by OS builder, they are public, aren't they?

No worries - perhaps others in the list know something? For practical purposes I can use the binaries I've found and go ahead try to make use of it, but these binaries are not distributable there is little point of doing that.

Yioryos asked the same question last year but for more specific case of the usage of libvmeta in flashplayer and only for XO-4 case (these binaries weren't publicly available too, but we managed to fish it out from Australian F18 distribution - perhaps you were the one packaging it :) ). This time around the it is for the more general purpose of using libvmeta as general codecs, for both XO-1.75 and XO-4.

Thanks, but etna_viv is the 3D driver for GPU acceleration. I may look into that as the Vivante driver in the XOs has definite problems too, but the question I'm asking (marvell-ipp) is for more media playback acceleration (h264 codecs and the like). (Btw the vivante 3D driver - libgfx etc are in the rpmdropbox so that's not a problem).

cheers!
