Using DVTB in an IPNC camera rather than the EVM

Vicki Henderson59742

We are trying to use the DVTB that comes with the dvsdk 1_30_00_40 to do a simple capture from the sensor in the camera.

The setup is

===========================================================================================

<DVTB> $ getp vpfe
       device                    => /dev/video0
       standard                  => 0
       format                    => 1
       input                     => 2
       width                     => 720
       height                    => 480
PASS: getp

<DVTB> $ getp videnc1
       codec                     => mpeg4enc
       encodingPreset            => 0
       rateControlPreset         => 1
       maxHeight                 => 480
       maxWidth                  => 720
       maxFrameRate              => 30000
       maxBitRate                => 2000000
       dataEndianness            => 1
       maxInterFrameInterval     => 0
       inputChromaFormat         => 4
       inputContentType          => 0
       reconChromaFormat         => 4
       topFieldFirstFlag         => 0
       inputHeight               => 480
       inputWidth                => 720
       refFrameRate              => 30000
       targetFrameRate           => 30000
       targetBitRate             => 2000000
       intraFrameInterval        => 30
       generateHeader            => 0
       captureWidth              => 0
       forceFrame                => 0
       interFrameInterval        => 0
       mbDataFlag                => 0
       numframes                 => 1800
PASS: getp

===========================================================================================

when we run the function "func videnc1 -t capture.yuv --no-dsp" we get:

----------------------------------------------------------------------------------------------------

<DVTB> $ func videnc1 -t capture.yuv --no-dsp
[DVTB-LOG]: dvevmStFuncDispatcher.c: Starting Thread for command <videnc1>

what are we missing? I have tried input 0 and 1 as well as 2 and they just say that input not connected.

Hi Vicki,

Can you please let me know the DVTB version number?

Also, there might be a sample dvs DVTB script file enabling raw capture. If yes, can you give it a try?

The program (when run in the camera) reports

"Digital Video Test Bench For DM355 ( DVTB ) Ver 1.10.000"

I looked in the scripts directory and did not find any .dvs file that identified itself as doing raw capture.

If you have one or know of one we would be delighted to try it.

One key question is "does the DVTB work in the environment of the IPNC camera since the IPNC camera is not the EVM.

Thanks -Vicki-

Vicki,

If you are using the same drivers that are used as in DVSDK demos then DVTB should work straightforward. If not, then DVTB is not guranteed to work as is.

You might need to update the driver wrappers. xxxVpfe.h & .c

Prem

As far as I know we are using the same drivers that are used in the DVSDK. The rules.make file points to that dvsdk. Is there any way for us to be sure?

Also we went into the code and found that the call to VIDENC_create() was failing but it is not clear if there is an error somewhere to tell us why. We are using extendedParameters.

Vicki,

The DVTB log which you've posted in this support forum thread shows some driver call failures.

Can you try running the capture driver sample app from the package?

Regards,

Prem

Just to add, On IPNC we use a sensor which goes through the same V4L2 driver interface where as on EVM we have TVP514x. So if the DVTB assumes any specific capture device, then we might face problem. Else, DVTB tests should work straight forward.
