PROCESSOR-SDK-AM62A: Query on the 4k video streaming

Sajan Saji
Intellectual 520 points


Hello Expert,

I streamed the 4k video using IMX219 in small display of 13 inch (kmssink) without any seemable issues. Now tried with a large screen of about 27 inch. Seems horizontal lines in the screen when running the simple pipeline. If I use filesink and view video or image there is no issue. Only in kmssink of this monitor. 



Warm Regards,
Sajan

    Hi,
    AM62A only supports upto 2048x1080 @ 60fps resolution. Do you still see the same issue at lower resolution? If so, would recommend checking with another monitor/panel.

    Hi Divyansh,

    I am running 3280x2464 @ 15 fps. It works in filesink and also in kmssink.
    I will get the video in 13.3 inch small full hd display only issue is with the large display of 27 inch.
    If I down scale the resolution of output to 1920x1080 it will work without any issue in same monitor.

    Hi Sajan,
    Few questions:
    1. What is your hardware setup? Is it TI's SK-AM62A EVM or a custom board? If it is a custom board, what bridge is being used to convert DPI to HDMI?
    2. To isolate the issue to Display SubSystem (DSS), can you please run kmstest in both displays to see if you still see abnormal output on 27inch display?
    3. Please detail both displays you are using. Are both HDMI based? Or is the 13inch display DPI based?
    4. For any/all HDMI displays, can you please connect them to your PC, run the following and share the output?

    1. cat /sys/class/drm/card0-HDMI-A-1/edid > p.txt
2. On ubuntu machine, install edid utils $sudo apt-get install read-edid
3. cat p.txt | parse-edid Checksum Correct

    5. How are you setting 3280x2464 @ 15 fps this resolution for your HDMI and/or DPI panels?

    did sudo apt-get install read-edid and how can I get p.txt. When I checked /sys/class/drm/card1-HDMI-A-1 edid file but seems nothing in that.

    Just enter kmstest in linux. Refer: https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1521056/faq-am62p-display-subsystem-dss-basic-debugging-and-forum-best-practices

    1. cat /sys/class/drm/card0-HDMI-A-1/edid > p.txt  ==> this generates p.txt
    2. was the display connected to the PC where you were running this?

    Hi,
    You need a 4K display which supports your particular resolution at the required fps for this to work. The EDID should be able to get that mode information from such display.

    What you are trying is not actually rendering the display at that resolution. Rather the frames from that resolution is being compressed into the best mode (1080p) your HDMI display(s) are able to support. This compression may not be reliable and it is expected that you only supply display supported modes into your userspace application.

    Mode0 shows 3840x2160 is supported in the monitor.
    Below this, I only see 1920x1080 as next highest resolution.

    This high resolution is unlikely to work with AM62A.
    To cross check, you may connect to EVM, and run:

    modetest -M tidss

    to check all available modes along with the fps these modes your monitor supports.
    From this fps, you can check if this mode can be supported by EVM at that fps.

    Display supports 4k. But Display subsystem compatible up to 2048x1080 @ 60fps, Am I right?
    It means that, no problem in saving the 4k video to a preferred location.

    Warm Regards,
    Sajan

    Correct. With the display connected to the EVM, can you share the output of:

    modetest -M tidss
kmstest --flip

    If the source of video supports receiving 4K video, you should be able to save the video on filesystem.

    Okay. I checked modetest -M tidss yesterday seems full hd.

    Can you share the modetest -M tidss? 
    It seems your latest display is 4K, but the next mode that can be supported by AM62A is FullHD.
