CoreELEC 19 Matrix Discussion (Kodi RC)

No, it does not working http://ix.io/2PnL

Last working build was here CoreELEC 19 Matrix Discussion (Kodi RC1)

Yes.
Updating to stable is available as an option in settings

Gave up on the wifi adapter below.
Worked perfectly fine before most current nightly, but will not function stable anymore directly after updating.

Is there any changes in current nightly that might explain the erroneous behaviour …?

I had a image ready, deleted it because you removed the post. Will take a look later these days as we are currently searching another issue.

Thank you.
I deleted my earlier post because i thought I should rule out all other variables first.
I did now ;).
Sry about that :blush: and thanks for looking into this !

Regards Atreyu

You have any idea when it stopped working?
Last changes about this driver is long behind:
https://github.com/CoreELEC/CoreELEC/commits/coreelec-19/packages/linux-drivers/RTL8812AU/

Also maybe post a debug log:

I have only a few nightly images what you can try back. There was no back done before:

Yes, directly after updating to latest nightly.
I am on the move now,but I will produce necessary info when I am back (which should be tomorrow).

20210210?

So 20210207 was working?

I think I’ve found the reason for this skipping issue now after some testing. It happens if I use 10 B-frames in the encode, 8 B-frames seemed to be fine.

Looking at the player debug info while testing, the a/v value was somewhat higher with 10 B-frames (as they do increase latency) and it looks like Kodi skipped a frame if it exceeded 100 ms or something like that. And as mentioned, it only affects HW decoding on my Odroid N2, software decoding is fine.

Is this something that should be reported to the Kodi devs or strictly related to the amlogic-ng stuff?

You can test with these two files.

thank you

Yes, the 07 nightly worked.

Can you try multible reboot? Maybe it’s a timing issue.

And if it works every time please try this image again also with multiple reboot if is working or not:

no, its doesn’t working every time reboot http://ix.io/2PrF

but this every time working http://ix.io/2PrK

If I understand correctly, you are experimenting with toolchains, can you try this one?

But currently, update channel is set to “none” and only available channel seems to be “CoreELEC 9.0”. Seems not to be ok!?

@as_id please try this new image (kernel_overlay):

EDIT:
and please run lsmod|paste once when it’s working and also if it is not working.

Ok, but I can only in the evening, after 22:00 Moscow time

can you please make one dmesg|paste with 20210207 and one with 20210210, thank you.

NFS worked fine with early Matrix builds. Then at some point it broke after update. Videos play with heavy framedrop even on low bitrates (looks like a some kind of buffer underrun) but audio is OK. Samba works fine, but my library is on NFS and I don’t like the idea of recreating it.

I can confirm this skip frames on one box, and it works on another…
I will check later this week if I have a patch for it.
