master has color issues on imx6 in video replay (mesa related?)

classicCuboxiuser · August 22, 2020 at 8:20 AM

something like this?

audio spdif and video codec issue 20200808 nighltly build cuboxi4pro

i am a total noob in programming so i don't know if i need instal more before it's working as it should.

i am in thinking it's framework is finished and only personal addon's are needed to install. but i could be wrong.

i am back to old version.

rdorsch · August 25, 2020 at 10:08 PM

Yes, I have no spdif, I can just confirm that the HDMI audio works well.

Thanks for recording the video, it shows the same effects as I see.

I managed to build kmscube:

Code

rd@h370-wlan:~/tmp.nobackup/git/LibreELEC.tv$ cat ~/.libreelec/options
ADDITIONAL_PACKAGES="$ADDITIONAL_PACKAGES kmscube"
rd@h370-wlan:~/tmp.nobackup/git/LibreELEC.tv$

and

kmscube does not compile

Still need to find a good way to run it.

rdorsch just build the kmscube package and copy the binary to storage. You don't need to actually include it in the build

rdorsch · September 11, 2020 at 10:51 PM

lrusak Sorry my question was not how to get it to the storage or image, I do not know how to start it. Can I start it from the kodi UI? can I start it in an ssh session? do I need to write a systemd file and start it before kodi starts? Or something else?

rdorsch you will need to do it from ssh. You will need to stop kodi first

systemctl stop kodi

./kmscube -A -D /dev/dri/card0

or

./kmscube -A -D /dev/dri/card1

Many thanks, lrusak

kmscube works without any issue, colors look ok, nothing similar to the colors when playing videos.

I just double checked (since I upgraded to a newer libreelec build) that the orignal color issue is still there (best illustrated with the video linked in the post from classicCuboxiuser above). I do not believe that it is a performance issue, since there seems to be no dependence on the resolution of the video.

Do you have any other ideas on either how to repro and analyse the issue with standard tools or debug it?

Thanks

Rainer

Could be to do with the fact that there is no default support for NV12 in mesa for etnaviv (last I checked it didn't merge).

I have a patch somewhere to enable YUYV output instead which etnaviv natively supports. This is the only other thing I can think of really.

rdorsch · September 18, 2020 at 7:34 AM

lrusak : For NV12, are you referring to

Pipeline · Christian Gmeiner / mesa · GitLab

?

For the YUYV patch, can you share it or do you want to merge it to libreelec and I can do a test run with master?

thundy · September 21, 2020 at 3:12 PM

Hi rdorsch ,

Thank you for reviving this thread and sorry for not replying quicker. I didn't receive the notification either. I guess I need to find the e-mail settings.

If it helps I can try to apply those patches and test. Maybe @Irusak did it already ?

rdorsch · September 23, 2020 at 10:00 PM

thundy Feel free to test, I would have hoped, that lrusak confirms that this is at least the right patch before I have a look onto it. It would also be an option to reach out to the mesa community, but I know almost nothing on these topics (just learnt that YUV was used for TVs to support b&w and color TVs with the same signal).

rdorsch · November 17, 2020 at 10:29 PM

The color artefact issues seems to be resolved on latest master :-))))

master has color issues on imx6 in video replay (mesa related?)
