SK-AM62P-LP: SK-AM62P-LP:VPU Use Error.

Hi Xiongwei,

Does this work on your setup? Also, do you have the mp4 file to playback?

gst-launch-1.0 -v filesrc location=bbb_1080p_aac.mp4 ! qtdemux name=demux demux.video_0 ! \
h264parse ! v4l2h264dec capture-io-mode=dmabuf ! kmssink driver-name=tidss sync=false

Hi Suren,

What settings are you talking about？

I have mp4 file to playback.

I use the command that you show to me.The same error appeared.I use gst-play-1.0 can playback mp4 file.So why gst-launch-1.0 can not？

Whether the user manual dose not match the SDK image？

Can you change kmssink to  "kmssink driver-name=tidss sync=false force-modesetting=true" and see if it helps to display.

Also can you stop weston before running the pipeline.

systemctl stop weston

Best Regards,

Suren

I stop weston,and change kmssink，but it didn’t work.

Xiongwei,

Let me verify it on AM62P board and get back. Are you using 9.1 SDK software to test video decoding?

Best Regards,

Suren

yes,SDK vision is 09.01.00.08.

Hi  Xiongwei,

I ran this on AM62P board that I have.

It seem to be working fine on my end. 

Attached is the file for your reference:

Hi Xiongwei,

Have you stopped the weston service before trying this pipeline? When you boot up the 9.1 SDK image on AM62P, you should see an App launcher page which runs on weston, so I request you to stop weston using " systemctl stop weston" and then try out the pipeline.

Best Regards,

Suren

Hi Suren，

I have stopped the weston service .

Are you using SD card as the boot media to verify the usecase of video decoding? Can you try with a different SD card and flash the default wic image again and see if it helps. I am suspecting something is not correct in your setup.

Hi，Suren

I created SD card agian，and use image you told me.But it don’t work.

Does it work when you use wayland sink  instead of kmssink?

Best Regards,

Suren

How to use wayland sink  instead of kmssink，What is the command？

Hi Suren,

This command  work.
