C6a816x H.264 Encode Demo Frame Rate

Gregory Goss
Prodigy 100 points

Other Parts Discussed in Thread: TVP7002

When I run the H.264 Encode Demo on the C6a816x EVM the resulting file: dm816x_1080p60_encode.264 gets written to the /usr/share/ti/data/videos directory. 

If I copy this file to my PC and view it using Windows Media Player or RealPlayer it plays at half the rate is should.

Has anybody else noticed this?

Does this .264 file not have the correct frame rate in it.  Does it have any frame rate information in it.

I feel like it should play at 60fps, but is only playing at 30 fps.

Any help would be appreciated.

Thanks,

-greg

    After some investigation, I think I understand this better.  The .264 file produced by the TI-8168 is a elementary stream of NAL units.  It has no timing information.  The elementary stream needs to be muxed into a container such as mp4, which will then specify the frame rate.

    If anyone has anything to add to this or correct, please feel free.

    Regards,

    -Greg

    Hi Gregory,

     

    How you get H.264 Encode Demo? Where is in EZSDK?

    I am trying Video Encode on EVM DM8168 using OMTB.

    Can you look below link, I have post in this forum

    http://e2e.ti.com/support/dsp/davinci_digital_media_processors/f/717/p/129692/464564.aspx#464564

    This is the script that I edit:

    dual_display_encode_decode.oms

    If you look in this script you can find where the output is specified.

    You also have to uncomment out the line that gives write permission to that file.

    #To enable write to SD card change mode to file
    omx setp 0 h264venc data_opmode file
    omx setp 0 h264venc outfile /usr/share/ti/data/videos/dm816x_1080p60_encode.264

    Then I reboot the EVM, and use the touch screen to restart the demo.  I have not figured out how to stop and restart the demo process from the command line.

    It seg faults if I try to execute from the command line. 

    Also, to change the bit rate:

    omx api getparam  h264venc 0 0 1 OMX_IndexParamPortDefinition
    omx setp 0 h264venc OMX_IndexParamPortDefinition video.nBitrate 10000000
    omx api setparam  h264venc 0 0 1 OMX_IndexParamPortDefinition

    Hope that helps.....

    Hi Gregory Goss,

     

    Thanks for your reply.  I have also found that, it is working.

    Now i am trying encode video alone.

    Giving the component video input to capture from dvd player (720p60). I am trying to file write After encoding data. It was writing the encoded data.

    But when play that file (dm816x_720p60_encode.264), it was full green color on player. I did not get the video from display also via HDMI.

    FYI,

    I have put my oms here.

    please look, and if u did encode from external source like dvd player or camera, please give the oms script file.

    it will be helpful us.

    I have not tried 720p yet.

    I upconvert my sources to 1080p60 component before sending in to the EVM. That seems to be the only thing it supports.

    We are working towards different input geometries at the moment.  And they might involve software changes, but not sure yet.
