Hello everybody, this is my first post on the group - I need some help regarding playing video files with the Beagleboard, and I hope to learn enough in the incoming months to become useful on the list too 
So, I need to setup a Beagleboard XM system without X Window that must be able to
- wireless connect to the internet
- run Opengl apps
- play 720p video (at least using omapfb which should be faster than vanilla video output) and better using the dspboard to decode the stream)
I've struggled with several options (demo system provided with the board, Narcisuss build, Debian) for the last 4 weeks but still don't have found a good global solution
My best bet, for now, have been to bitbake a 3.0.25+ kernel with Open Embedded, with the help of some obscure IRC logs (both concerning wrong OE recipes) I've been able to have OpenGL running
WIFI is ok, using a dlink (realtek) usb adapter
The kernel is very responsive, very fast to boot (11 second from u-boot start to login prompt)
The last and very important point is video stream playing which I've not be able to use in accelerated mode. I must also confess that I still have a very very basic understanding of the beagle xm video system.
I'have bitbaked ti-gstreamer and installed on board with all the gstreamer required plugins.
The problem is... that I can't play anything with or without using TI* gstreamer functionnalities.

2) The problem
gst-launch --gst-debug=2 -v videotestsrc num-buffers=100 ! TIDmaiVideoSink displayStd=fbdev displayDevice=/dev/fb/1 videoOutput=DVI useUserptrBufs=FALSE
gives, amongst others info, two ERRORS
0:00:00.092742842 385 0x1588588 ERROR TIDmaiVideoSink gsttidmaivideosink.c:1968:gst_tidmaivideosink_alloc_display_buffers: useUserptrBufs=TRUE can only be used with V4L2 displays

I don't understand the complain about useUserptrBufs. Considering the error about buffer allocation I suspected a bad configuration about memory shared between CPU and DSP, and I did this
/usr/share/ti/ti-dsplink-examples/ti-dsplink-examples-loadmodules.sh
gives
You have 76964kB total memory for Linux
Then /usr/share/ti/ti-dsplink-examples/ti-dsplink-examples-run.sh
The forth first examples seems to run fine (LOOP, MESSAGE, MESSAGEMULTI, MP_LIST)
then the other ones all fail giving

I found this http://processors.wiki.ti.com/index.php/Troubleshooting_DSPLink_configuration_issues#Problem:_PROC_start_failed_with_configuration_mismatch.2Ffailure
it could be related with cause 2 or cause 3 but unfortunately I don't have the required skills to correct the problem
I really don't see what to do... Anybody can help ? Thanks
