[Openchrome-users] openchrome and gstreamer

[Marcus Priesch]

Hi Ondrej,

i have a me6000 (which also has cle266) running fine with gstreamer and
xv out ... 

i donno gstreamer-properties, i have hacked up a simple pipeline with
the python bindings and it really runs great ... sort of video overlay
from a bt878 capture card ... 

i would suggest to check the xorg log for 

	(II) Loading extension XVideo

and something like ... 

	(II) VIA(0): [Xv] Using PCI DMA for Xv image transfer.
	(II) VIA(0): Benchmarking video copy. Less is better.
	(--) VIA(0): Timed   libc YUV420 copy... 14541007. Throughput: 24.5 MiB/s.
	(--) VIA(0): Timed kernel YUV420 copy... 14450003. Throughput: 24.6 MiB/s.
	(--) VIA(0): Ditch    SSE YUV420 copy... Not supported by CPU.
	(--) VIA(0): Timed    MMX YUV420 copy... 3119115. Throughput: 114.1 MiB/s.
	(--) VIA(0): Timed 3DNow! YUV420 copy... 10435735. Throughput: 34.1 MiB/s.
	(--) VIA(0): Ditch   MMX2 YUV420 copy... Not supported by CPU.
	(--) VIA(0): Using MMX YUV42X copy for video.

i'm not sure if you need drm and dri for it to work ... i have it 

if your xorg log tells you that you have Xv, try out a simple pipeline
with gst-launch ... 

hope this helps

greets,
marcus.
