Hi Laurent I am working on a demo-application for displaying a videostream on a beagleboard. Now I have seen that you have done something similar, but if I run your "live" application out of the omap3-isp-live repo, then I get the following error: root@beagleboard:~# modprobe omap_vout video1_numbuffers=3 video2_numbuffers=3 video1_bufsize=771200 video2_bufsize=771200 vid1_static_vrfb_alloc=n vid2_static_vrfb_alloc=n root@beagleboard:~# ./live fb size is 800x480 Device /dev/video6 opened: OMAP3 ISP resizer output (media). viewfinder configured for 2011 800x482 AEWB: #win 10x7 start 16x74 size 256x256 inc 30x30 trying to allocate 800x480 Device /dev/video7 opened: omap_vout (). 3 buffers requested.

Buffer 0 too small (771200 bytes required, 770048 bytes available). error: unable to allocate buffers for viewfinder. error: unable to set buffers pool This seems to happen in the v4l2_alloc_buffers function of v4l2.c when memtype is V4L2_MEMORY_USERPTR. Has it been broken in the newer kernel versions? Do you have hint where I should start fixing? I am using the following config: beagleboard-xm linux-omap branch, tag v3.5 leopard imaging li-5m03 with mt9p031 Greetings, Florian -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
