How to do it ?

Hope help!

Hi Pushpa,

Thank you for your fast response ,and I follow you

gst-launch -v v4l2src device=/dev/video0 ! ffmpegcolorspace ! videoscale ! video/x-raw-yuv,format=\(fourcc\)UYVY, framerate=\(fraction\)30000/1001, width=720, height=576 ! tidisplaysink2 -v

but,  the error just a small section display as followed:

..........................

ERROR: Pipeline doesn't want to pause.
ERROR: from element /GstPipeline:pipeline0/GstV4l2Src:v4l2src0: Device '/dev/video0' cannot capture at 720x576
Additional debug info:

............................

Why? how to do about it?

Thanks!

Hi Jay,

  Check whether your PAL camera works fine.  You can check it by  connecting the camera directly to TV .                                                                                                                   Because the same is working fine for me

Which version of DVSDK are you using?

Regards,

Pushpa

Hi Pushpa,

Thank you for your response!

The DVSDK version is   dvsdk_dm3730-evm_4_02_00_06_setuplinux.  

When  I  do the experience about "ti-dmai-apps" with the execulable file "video_loopback_dm3730.x470MV",

the camera image  can display on the Seven-inch LCD screen.  so ,my hardware connection  has no problem.

The bug about the DVSDK version?

Thanks!

Hi Pushpa,

I connect  the PAL camera to TVP5146M2IPFP pin 80 about VI_1_A .

is my connect  wrong ?

Thanks!

Hi Jay,

   If the video loopback is working fine with camera, then there is no problem w.r.t camera and hardware connections.

Make sure the camera you are using is PAL.

You can further know what's happening, by enabling the debug traces:

GST_DEBUG=3 gst-launch -v v4l2src device=/dev/video0 ! ffmpegcolorspace ! videoscale ! video/x-raw-yuv,format=\(fourcc\)UYVY, framerate=\(fraction\)30000/1001, width=720, height=576 ! tidisplaysink2 -v

Hi,Pushpa

I am sorry , only just I see your respones and thank you for your enthusiasm.

I try your command,as follows:

Hi

When I use this command on the ti-dmai-apps application:

the path  is   "usr/share/ti/ti-dmai-apps"

./video_loopback_dm3730.x470MV -O lcd  

 The PAL camera(CCD) can display on the LCD screen,and then execute your command

gst-launch -v v4l2src device=/dev/video0 ! ffmpegcolorspace ! videoscale ! video/x-raw-yuv,format=\(fourcc\)UYVY, width=720, height=576 ! tidisplaysink2 -v

successfully, and I can see the video image in the LCD screen.

But I must execute the first command ,or else your commad is reported error

Why?

Hope help!

Hi

I have already  found that this command just support the resolution about "width=720, height=576",

if I repair the width or height to other value ,for example  "width=320, height=240",  it will turn out the same eror

Have you encountered this strange problem?

jay yang

videoscale had a problem, you should use TIVidResize replace it.

Hi,

I am new to driver development, I am using DM3730 processor, ov2643 camera sensor and arago toolchain i am using, i want to capture image and video using gstreamer please suggest me its available in Texas instruments if any supported plugins available in the sense provide related links. if prebuild binaries is not available in the sense please let me know cross compiling gstreamer source code.

Thanks,

Murugavel.
