Hi,everyone!
I have a DM3730 board, and I want to trasmit some video data to webserver wit GStreamer
the website is about example GSstreamer pipelines ,http://processors.wiki.ti.com/index.php/Example_GStreamer_Pipelines#OMAP35x
I have referenced the OMAP35x's Loopback Video command ,
command as followed :
gst-launch -v videotestsrc ! TIDmaiVideoSink videoStd=VGA videoOutput=LCD accelFrameCopy=FALSE sync=false
at the Ubuntu ,
root@dm37x-evm:/usr/share/ti/dvsdk-demos# gst-launch -v videotestsrc !

why?
Hope this help!
Thanks
Hi li,
Try "tidisplaysink2" instead of "TIDmaiVideoSink"
gst-launch -v videotestsrc ! tidisplaysink2
Regards,
Pushpa
Hi Pushpa!
You are right! Thank you for your fast respond!
but,I just get a dispaly as shown in figure:
I want to display the composite camera with PAL , I use the DM3730 chip
How to do it ?
Hope help!
Yang
Hi Yang,
Of course yes, it displays the above video because 'videotestsrc' produces a standard test video which consists of set of colour bars with some random noise.
If you want to display the captured video, you have to make use of v4l2src instead of videotestsrc.
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,
Thank you for your fast response ,and I follow you
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 720x576Additional 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?
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?
I connect the PAL camera to TVP5146M2IPFP pin 80 about VI_1_A .
is my connect wrong ?
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?
jay yang
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?
videoscale had a problem, you should use TIVidResize replace it.
