Re: Using freerunner as webcam display
[cut] I think it's the CPU which is around 90% already at 2fps. Another problem is, that the mpeg stream sometimes seems to be corrupt which crashess mplayer after some time. So I did a 'while true; do mplayer...; done' around and set codecs and other parameters by hand to avoid the autodetection. Keep in mind that there are several versions of mplayer compiled. Each of them are better suited for different video formats or other factors: There is some special version of mplayer with glamo support: http://downloads.tuxfamily.org/3v1deb/openmoko/mplayer-glamo.tar.bz2 Also PaulTT has compiled a version of mplayer with tremor available: http://www.paultt.org/downloads/openmoko/mplayer_dev-SVN-r29155-4.1.2_armv4t.ipk Or you can use one from FSO: http://downloads.freesmartphone.org/fso-unstable/feeds/armv4t/mplayer_0.0+1.0rc2-r12_armv4t.ipk I have seen a note on wiki that says: The kernel is now (July 2010) configured to use kernel-mode switching (kms) for glamo. The glamo video driver has no direct control over glamo anymore and cannot use accelerated video playing until a new driver is written. http://wiki.openmoko.org/wiki/Video_Player Hope this will help you.

I found out, that is mainly fbdev which costs the high CPU load. with x11 and no rotation I get 60% CPU at 10fps and a fluent movie. x11 and rotation is about 80%CPU. fbdev is at 80-90%CPU with or without rotation and a not so smooth video any more. xrandr -o 2 seems not to work. So I can live with that - after all it's actually only a 'proof of concept' without any relevant importance ;) I also updated to a new image (last one was more than 1 month ago) and I was surprised about the speed improvement - launching applications and the reaction time of certain controls (especially disabling dimming and suspend) are really impressive now!

Re: Using freerunner as webcam display
Consider, if you can switch recording to MPEG-2. You can play MPEG-2 video at much more fps with Glamo 2-4-2 timings. Or you can try this: http://unadventure.wordpress.com/2008/06/08/accelerating-in-my-pocket/ and accelerate MPEG-4 on Glamo, but it's not yet ported to new kernels with DRI architecture.
