gst-launch playback problem

[Alex]

Hi all,

I'm trying to run gst-launch on omap-3630 (Archos 101 gen8 tablet).
I've compiled and installed kernel-side dsp driver and binaries
(kernel 2.6.29, binaries L23.i3.8), and user-side libs according to
BeagleBoard DSP Howto (elinux.org/BeagleBoard/gst-dsp).
I have 2 framebuffers about 9Mb each and 1024x600 32 bpp screen. I
couldn't run xserver-xorg-video-omapfb and have to use fbdev for X
(though not sure, that it's important).

I try to run gst-lauch as:
gst-launch-0.10 filesrc location=/big_buck_bunny_480p_surround-
fix.avi ! decodebin2 ! omapfbsink

Playback starts, but the image is so teared that nothing can be seen
at all, and there's no sound...
In dmesg I see the following:

ioctl QUERY_PLANE
ioctl SETUP_PLANE
omapfb_setup_plane
ioctl SETUP_MEM

ioctl UPDATE_WINDOW
ioctl failed: -22
ioctl WAITFORVSYNC
pan_display(1)
// ...........

ioctl SETUP_PLANE

I have no idea what is wrong...
Any clues will be appretiated!

Hi,

Sorry for the delay.

It using X, or fbdev, or anything shouldn't be a problem. It should
even work on the console.

I would try simpler pipelines first, such as 'videotestsrc ! omapfbsink'.

This looks bad, I don't think omapfbsink is working. Have you tried
any other software that uses the OMAP fb overlays?

Cheers.
