Hello

  we are workign with OMAP3530-beagle. We compiled ti-dvsdk_omap3530-evm_4_01_00_09 for beagle board successfully. But after booting when we are running gstreamer demo under multimedia we are getting the following error and not displaying anything on the DVI..

I searched in the internet. i didn't find any solution.

for cmemk i'm using the following command to insert using script in /etc/init.d/loadmodule-rc

modprobe cmemk phys_start=0x86300000 phys_end=0x87200000 useHeapIfPoolUnavailable=1 allowOverlap=1

There are my bootargs

setenv bootargs 'console=ttyS2,115200n8 root=/dev/mmcblk0p2 rw ip=off mem=99M@0x80000000 mmem=99M@0x88000000 purate=720  omap_vout.vid1_static_vrfb_alloc=y omapfb.mode=dvi:hd720 omapdss.def_disp=dvi omapfb.vram=0:3M  rootwait'

Even when we try to run decode or encode as per OMAP3530_Software_Developers_Guide.pdf,  in beagle board we are getting same error.

Please help us to solve this issue.


Thank You

    Hello,

    Please check yours bootargs.

    Load the kernel modules before running gstreamer pipelines:

    target # /etc/init.d/loadmodule-rc restart

    You could use gstreamer examples from here:

    http://processors.wiki.ti.com/index.php/Example_GStreamer_Pipelines#OMAP35x

    Hello Margarita,

      Thanks for the reply. We are already loading the modules on launching the application. We solved the error. But still gstreamer not playing the video.

    ti-dvsdk_omap3530-evm_4_01_00_09 Matrix_gui not working on beagle board. After booting display rotates into 90 degree and mouse/Keyboard not working. So, I'm using DM3730 Matrix_gui from ti-DVSDK_dm3730-evm_04_03_00_06 package and copied dm3730 directory files into omap3530 directory and  compiled along with OMAP DVSDK  .

    Matrix GUI booted successfully.

    Now, in the matrix GUI i'm trying to run demo in  multimedia->MP4 Decode (H.264+ AAC) and multimedia->Decode-> startdemo Nothing happening.

    Is that because of we are using DM3730 GUI? even QT also new to us.


    We will try the gstreamer pipelines examples and getback to you.

    Thank you

    Hello Eswar,

    Let me know the result. You could try and examples from OMAP3530_Software_Developers_Guide.pdf

    The matrix_gui should be stopped, when you play gstreamer pipelines.

    Best Regards,

    Margarita

    Hi Margarita,

    I run the following command as per Software developers guide.

    gst-launch filesrc location=/usr/share/ti/data/videos/davincieffect_480p30.264 \
    ! typefind ! TIViddec2 ! TIDmaiVideoSink rotation=270 videoOutput=DVI videoStd=VGA -v

    I changed videooutput=DVI insted of LCD.

    After running the above command matrix-gui turned off and the following error message came.

    root@omap3evm:~# gst-launch filesrc location=/usr/share/ti/data/videos/davincief

    --> again i rebooted and killed matrix-GUI using ps. And run the above command. Same as above error came.

    What can we do now.

    Thank You

    Hello,

    You could try this:

    gst-launch -v filesrc location=/.../sample.264 ! TIViddec2 codecName=h264dec engineName=codecServer ! TIDmaiVideoSink videoStd=VGA videoOutput=DVI sync=false

    and let me know the result.

    Hi,
     I tried the command.

    gst-launch -v filesrc location=/.../sample.264 ! TIViddec2 codecName=h264dec engineName=codecServer ! TIDmaiVideoSink videoStd=VGA videoOutput=DVI sync=false

    First i re-initialized the modules.
