EZSDK DM8168 Video Encode Process

Prodigy 210 points

Hi All,

 

           I am working on EVM DM8168 for video encode process.

           How i can do encoded video send out through Ethernet using Socket?

         I am using the OMX and OMTB for Video Encode from TI-ezsdk_dm816x-evm_5_01_01_80 (EZSDK).

 

 

Thanks & Regards,

    The ethernet streaming is not supported thru OMTB.  To better accomplish this you'll need to build a C-base IL-Client (modeling the omx_05_01_01_08/packages/ti/omx/demos/decode.c source) such that instead of decode you'll use the OMX Encode component which will receive frames from the task that is receiving the video frames.  We plan to have better examples of full encode and decode chains in the upcoming release.

    Hi,

    Thanks for your reply.

    My first aim is send out the encoded video packets over Ethernet.

    I used video encode and decode using dual_display_encode_decode_nopause.omx  from  targetfs/usr/share/ti/ti-omtb

    Its working well.

    I want to do encoded video send out through ethernet,and see the video in software decoder like VLC.

    How i will run the encode video processing alone using .oms script file?

    what are the steps should i follow for encoded video send out ethernet?

    I tried the decode video test using omx_05_01_01_08/packages/ti/omx/demos/decode/decode_test.c source , but i got the following errors.

    FYI,

     

    root@dm816x-evm:/usr/share/ti/ti-omx# ./decode_a8host_debug.xv5T 1920 1080 /usr/

    Hi Marcus,

     

    I tried the decode video test using omx_05_01_01_08/packages/ti/omx/demos/decode/decode_test.c source.

    Its working well. I need to do video encode alone using the OMTB(.omx). Can you say the way to find out the encode source files and scripts for encode alone.

    It will be helpful for us.

     

    Thanks & Regards,

    Even though i tried with dual_display_encode_decode_nopause.oms, decoded video can display in lcd tv thro' hdmi. But i could not write the encoded data in targetfs path.

    It will be helpful for us.
