Hi all,

i made application as shown in diagram as below.

1. - Read h264 data from mp4 file 

    - VDEC decoder decode h264 data and give yuv420sp output

    - INDTXSCWB do croma conversion from yuv420sp to yuv422

    - Display video

2. - Read yuv420sp data from yuv file.

    - scale data from 1280x720 to 360x480 and also do croma conversion yuv420sp to yuv422

    - Display video

Now this above application work well but most of time OMX component DEIMDUALOUT crash at configuration time. Please find log in attachment.

    Hi,

    I manage to solve the above problem. it was just problem in sequence of configuring DEIMDUALOUT parameter. So above demo now work perfect on platform netra.

    Now I modify above application to instead of reading yuv data from file. I capture yuv420sp using V4l2 and add another OMX component VENC for encode data to h264 format and stream on network.

    I follow initialization sequence of OMX component as follow in application.

    1. V4l2 capture

    2. VENC

    3. VDEC

    4. INDTXSCWB

    5. DEIMDUALOUT

    6. Display

    Now problem is here that after initialization of INDTXSCWB when i configuring channel per handle parameter of DEIMDUALOUT then system halt that i lost console access. now just one option left is to reboot system.

    I also check it by changing sequence of the initialization of INDTXSCWB and DEIMDUALOUT then system halt on INDTXSCWB configuration.

    so i have query that how can i run this demo or is it limitation of VPSS firmware ?. I can not provide VPSS log for this because  i lost console on this crash.


    Thanks in Advance,
