    Default TI Shows Off Impressive, Experimental Wayland Demo

    Phoronix: TI Shows Off Impressive, Experimental Wayland Demo

    Rob Clark of Texas Instruments presented on the second day of this year's GStreamer Conference where he talked about GStreamer for the TI OMAP4, DMA-BUF, DRI2Video, and other low-level Linux multimedia work he's engaged in along with work on TI's OMAP Linux graphics driver. Rob ended up showing off an impressive but experimental demo of video playback work he's doing with Wayland...

    Is is just me, or does the video being played back suffer from tearing?

    I really don't see how this is impressive...

    Exactly.

    A dual core ARM system shouldn't have any issues with 1080p, especially when you consider the raspberry pi can do it just fine.

    Playing one 1080p clip is not too impressive. (And to be precise, it was actually a 2k clip.) OMAP4430 and up can play two 1080p clips in parallel on bare metal

    The challenge comes to integrate the video with the UI. So come back when you have 1080p playback in weston on r-pi ;-)

    On fully open drivers too, no?

    Well, you're right, it isn't impressive that a decent ARM can hande 1080p just fine. It's impressive that they have come so far with Wayland, though.

    It's not really ARM which decodes, but special HW. In case of PandaBoard HW decoder is called Ducati.

    I wonder whether I can use Wayland with on the Rasbeery Pi. Is it possible at this point? I've seen a video, but I don't know whether that's Wayland how it is out-of-the-box or maybe a patched one...Are their any special drivers needed to run Wayland on an Rasberry and can I use the regular sources of Wayland and compile it on Arch Linux (ARM) for the Rasberry Pi? Or will this be possible in the future?

    Playing a camcorder copy of a video on a screen through a player that probably isn't tear free itself - I think it would be pretty hard to tell. At very least the camcorder's frames wouldn't be synced with the video.
