DM365 DVSDK 4 Encode Demo Error

Randy Scheifele
Intellectual 550 points
Other Parts Discussed in Thread: TVP7002

Hello,

I have found some posts similar to my issue, but I haven't been able to resolve my issue based on the answers found in other posts.  I have the dm365 evm set up with the latest DVSDK (4.0) and I am having some issues running the encode demo.  I have a camera hooked up to the composite input and when I run the encode demo, it seems to print some messages like:


EVM: switch to tvp7002 HD video input
... [omitted]
tvp7002 1-005c: querystd, errorxxx, val =1, val1 = 1
Error: Failed to create capture device
encode: linux/Fifo.c:177: Fifo_put: Assertion 'ptr' failed.
Aborted

From the messages, it seems like the encode demo is trying to operate on the component input and not the composite input.  Is that accurate?  If so, how do I get the encode demo to run on the composite input?  Is there a different set of kernel command line parameters that I need to pass in via uboot?

As far as I know, I followed the steps in the user guide correctly and have everything set up correctly.

Any help would be greatly appreciated!

    Hi Randy,

    Out-of-box, when launching the encode demo from the Matrix application launcher, the demo is configured to use the component input. This is why in the quick start guide that comes with DVSDK 4.0 the user is instructed to hook up the component input. 

    If you wish to use the composite input, you would need to manually launch the demo from the command line, by passing -y1 (and/or -I1 if you are using DVSDK 4.01) as command line parameter to select composite NTSC. No need to change the kernel bootargs. As described in the Software Developers' Guide, you can check out the encode.txt file to find out all the options that are available to the demo. Alternatively, if you run

    ./encode -h

    the help text that appears would also explain the different options available.

    Hope this helps!

    Vincent

    Vincent,

    Thanks for the quick reply!  I was afraid you might say that I needed to pass -y1 into the encode application, because I've already tried that and it was unsuccessful.  Here is the output from the encode command:


    target#: ./encode -v test.mpeg4 -k -y1 -t 20

    Encode demo started.
    vpfe-capture vpfe-capture: IPIPE Chained
    vpfe-capture vpfe-capture: Resizer present
    EVM: switch to tp5416 SD video input
    Error: Failed to detect video standard, video input connected?
    Error: Failed to create video encoder: mpeg4enc

    From reading other posts, it seems like the most common error here is that the camera is hooked up improperly.  Are there any other reasons why I would get these errors?

    Thanks!

    Hi Randy,

    The demo should have worked if the input source was connected and powered on. Do you have other composite input sources you can try (e.g. DVD player)? Also, I am assuming that the demo worked fine out-of-box for you with component input, and that you haven't changed the bootargs from what the setup.sh script has configured for you. Is this the case? If not, you might want to re-run the setup.sh script so that the right bootargs are configured for you.

    If none of the above works, could you post the dump by prepending DMAI_DEBUG=2 to the demo command line? Also post your kernel bootargs (you can get them by running cat /proc/cmdline)

    Best regards,

    Vincent

    Hi Vincent,

    Thanks again for the quick reply.  Well, it turns out that the camera that I had hooked up was malfunctioning for some reason, and using a different camera fixed the problem.

    Thank you very much for the tips!

    Hi,

    I have the same issue here, trying to use the "encode" demo.
    I have a camera (sony HDR-CX115E) as YUV source and set the video input to COMPONENT :

    ./encode -I 3 -v /home/root/output_cap_720P.264

    When launching gstreamer with v4l2src it works well, and gets the frames as YUV frames so the input is ok.
    I launched the same line with DMAI_DEBUG=2 :

    $> DMAI_DEBUG=2 ./encode -I 3 -v /home/root/output_cap_720P.264
    Encode demo started.
