The reason we want rpmsg is to get h264 endcoding and decoding using

well? Andy is right that it is mm decode/encode I am interested in.

So if I have understood you right: For the time being, I should use
tilt-3.1 with syslink and gst-ducati (or some other gst element?) to get
mm h264 encoding/decoding working on the omap. And when rpmsg is in a
stable upstream/tilt kernel, I can switch to that and still use gst-ducati?

at the current time, as andy said if you want a workable GST with decoders and encoders using gst-ducat, the only solution is 3.1 kernel with syslink2.0. I am not entirely sure about the exact status of Linaro releases with this regards (rsavelti can comment on that), but for sure if you use a plain 'ubuntu 11.10' with the TI OMAP 'release' PPA packages installed (see http://groups.google.com/group/pandaboard/browse_thread/thread/6aa2cbe99c36919d) then you will get such a system. PVR drivers are working for UI, and PVR is used as well for video rendering (through GST pvrvideosink element). With all these packages installed, you can use gst-launch or any gst based application, and video codecs will be h/w accelerated through gst-ducati.

we are *currently* working on the next gen GST stack which will be based on 3.3+ kernel with rpmsg (aka syslink3) and a new graphics architecture based on our new omapdrm GEM based driver. This is work-in-progress at the moment, and we are publishing our 'experimental' work in our OMAP 'trunk' PPA (~tiomap-dev/omap-trunk in LP). At this point of time, we have updated libDCE , kernel, and firmware and we have some basic video decode working with this new stack, but 1) we haven't started the GST updates, 2) it's not recommended if you want something that 'just works'. Support for encoders, and support at GST level (gst-ducati) will be available in the coming weeks.
