DVSDK Demos Fail

Rob Tice

I have installed the DVSDK_3_10_00_16 package (using the GSG) in Ubuntu 10.04. I have written the Kernel (2.6.31) to the DM365 NAND Flash through a TFTP server and have the NFS mounted correctly. I can run ./loadmodules_hd.sh and ./interface with no issues. When I try to run the demos from the interface or the command line, i receive the following errors.

Encode Demo

Demo interface started at level 0.
Encode demo started.
Error: Failed to create capture device
encode: linux/Fifo.c:177: Fifo_put: Assertion `ptr' failed.
Aborted

Decode Demo (trying to decode the videos provided in the demo package)

Demo interface started at level 0.
Decode demo started.
CMEM Error: getPool: Failed to get a pool fitting a size 1479936
Failed to allocate memory.
Error: Failed to create BufTab for display pipe

Encode/Decode Demo

Encodedecode demo started.
Error: Failed to create capture device
CMEM Error: getPool: Failed to get a pool fitting a size 1024000
Failed to allocate memory.
Error: Failed to allocate buffer for encoded data

If i add the pool values in the error message to loadmodules_hd.sh and run the ./loadmodules_hd.sh and then repeat the process, I continue to receive new pool values that are missing. I am using a 720p/60 camera as the input device. Any ideas on a setting I have wrong, or a process I haven't set up correctly?

Thanks,

Try to run loadmodules.sh instead of loadmodules_hd.sh. I believe the latter has pool sizes that are tailored for running DMAI applications, whereas the former is meant for running the demos.

Also, you will get "Error: Failed to create capture device" is you have not connected 720P60 component input to the board.

As Vincent suggested, please use loadmodules.sh and check the setup, if the input source is correct.

If you still see the error, please run following from the command line and send us the log

DMAI_DEBUG=2 ./encode -v a.264 -y 3

Thank you for your replies. I was able to get the demos working. I had to wipe the pools that were pre-set and add in my own calculated pools.

Next question: Is there a way to make a program autostart after the kernel boots? For instance, could I have the encode demo start as soon as the kernel boots and save the video to a file with the file name being the time and date stamp?

Thank you,

You can create a script and put it in /etc/init.d. Similar thing is done to run interface demo at the time of bootup, have a look at http://processors.wiki.ti.com/index.php/DM3xx_filesystem_restore_procedure_in_DVSDK_3.10 ("Change /etc file to start demo at bootup" tab).
