Part Number: AM5728


Tool/software: Linux

Hi.

yesterday, you answer that IVA-HD can decode jpg with size(4096x4096).

we test it as below it. and gstreamer show error(kmssink gstkmssink.c:432:gst_kms_sink_show_frame:<kmssink0> error: drmModeAddFB2 failed: Invalid argument (22))

gst-launch-1.0 -v --gst-debug=3 filesrc location=./3456x3456.jpg  ! jpegparse ! ducatijpegdec ! kmssink

i can find it at Zlinux-4.4.19+gitAUTOINC+db0b54cdad-gdb0b54cdad\drivers\gpu\drm\drm_crtc.c.

internal_framebuffer_create function tell that drmModeAddFB2 can success  under width is 2048.

how can i decode jpg with size(3456x3456) ?

 Thanks a lot.

    Hi Lee,

    This error is from drm. DRM can not take this output of 3kx3k.  Decoding has no issue.

    Try filesink instead of kmssink to check the output

    If you want to display, you will have to scale down decoder output. But VPE also doesn't not support width > 2048.
    You may have to use software scaler pluggin if exists(ffmpeg)

    Hi.

    I decode size(3456x3456) of jpg and i get yuv from IVA-HD. and i want to display the yuv.

    For it, i need to call drmModeAddFB2 with width(3456)/height(3456), but driver(internal_framebuffer_create of gpu\drm\drm_crtc.c) don't make the size.

    I want to increase to max_width/max_height of drm_mode_config. If it is possible, I use scaler of VIDx in DSS and i will scale down (1920x1080) of yuv from (3456x3456) of yuv and display it.

    Thanks a lot.
