[TESTING] Linux 4.9 kernel and improved video stack for Vero 4K / 4K +

[jahutchi]

I’ve just started properly testing the 4.9 USB image and have hit a green screen.

For me this was in a HDR HEVC rip of Aquaman which I never had problems with on 3.14 kernel. The green screen occurred as I was skipping though the file.

Here is the mediainfo: https://paste.osmc.tv/apefutujar

After hitting the green screen I found that every video I attempted to play thereafter would not play and instead showed a green screen until I rebooted

After a reboot I was able to easily reproduce…I play Aquaman again and hit a remote button which I have mapped to the action: Seek(250) a few times in succession and bam…green screen.

Here are some logs for the second green screen incident following the reboot:

Very easy to reproduce so happy to provide more logs etc if required.

I can’t, sorry, next time.
It was fixed by reboot or me exiting to console to clear the arp cache and back from there to the gui a few times. I will when it happens again.
I reread, you mean a debug log when it works? I can do that when I get back home.

Right, yes. I assume the info in the Kodi log will be the same compared to the failed one. I’m interested in the differences in the kernel log.

Any chance of updated USB/SD images?

[sam_nazarko]

I’ll do some new images soon. For now, I’d like to make a few more changes.

I am very happy with this test version. Have been using it for some time now and don’t have any major issues. Great 3D performance also. Yesterday I have watched Avatar in 3D and this release still has some glitches, but this is a known issue and I can live with it this way. I think it is almost ready for release to stable?

Unfortunately still the same for me

Remind me - did unplugging and re-plugging the hdmi cable give you a proper picture?

I did, while the vero was unplugged. It required me to add the source in the tv again but was still showing low res and no cec. When i did the same before the updated version it went hd and cec for a while but a day or so later it was back to low res etc. I always leave the vero on and just put the tv to sleep

I have found a further issue. When playing TS recordings from tvheadend, or even just playing the raw TS file directly I find that the screen flashes black for a couple of seconds a time during playback. It seems to always be at the same points in the file.

If I boot back to the 3.14 kernel then the same file plays flawlessly.

Here is a debug log:

And here is mediainfo for a 100 second sample file:

I’m happy to upload the 100 second sample which demonstrates the problem if that would help.

Has bluez been changed? As of today, I can no longer pair my FireTV remote.

[bluetooth]# pair 1C:12:B0:A8:50:C2

[sam_nazarko]

No Bluetooth changes.

[rbronco21]

Should I break this out into support then?

Hi! Bad news: the recent updates do not seem to have fixed this,

Good news: debug logs and playing 2 videos (green display instead) here: https://paste.osmc.tv/gomesaqiho

After reboot, playing the same two videos normally, debug logs here: https://paste.osmc.tv/aboleliwon

We’re almost there … unfortunately, you forgot to

@tanio99

while that movie is playing, do that cat thing again

I’ve now uploaded the sample file which reproduces this to dropbox here:

testfile.ts

[sam_nazarko]

Cheers.

[grahamh]

I can’t reproduce that.

[sam_nazarko]

Likewise. Skimmed logs quickly. @jahutchi did you try playing testfile.ts from local storage (eMMC)?

[petersasi]

Sorry that cat thing was not obvious to me, you know all the cat videos on the Internet
Will try to search for the exact cat command when it happens next time.
Does this mean the above two logs are not useful?
