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

There have been no changes to picture quality in this update, just playback fixes.

Then working very well!

The contrast bug is still present.

There’s a fix in Kodi for this, but I suspect we will also need a kernel patch too.

This is coming.

Thank you very much for this hard work!!!

The issues i brought up are solved With this latest update, no circles anymore with failing startups, just the normal starts. Even switching between several resolutions 4K/24/60 and 1080p24/60 is going very well.

The yelly fish 300 is still buffering a bit from nfs, no real issue off course, as it’s just a test file. Maybe i’ll need to add settings like below.

<advancedsettings>
    <cache>
       <buffermode>0</buffermode>
    </cache>
</advancedsettings>

I’ll keep on testing.

Never mind, I forgot to push that contrast fix for Kodi. Can you try and test again?

I think a further patch to the kernel is needed but if you can test the Kodi only changes I’ve pushed for now regarding contrast that’d be handy.

Cheers

Sam

Please provide iperf3 results (both directions)

My h265 video files are now playing fine!! Thanks for fixing. For reference this was the issue where you just got the wait timer when playing a file.
Hitting pause and play a load sometimes overcame it and, curiously, it didn’t happen when amcodec was disabled and only affected my h265 mkvs.

Hope this is what you expected

  • 1st May 2020 - kernel, Kodi and microcode updated.
  • 2nd May 2020 - kernel and Kodi updated.

How do I do the update for the latest changes? Just like the first time?

/Söder

You can check for updates manually or wait for a prompt

I confirm also from my side that the last update fix the playback issue.
Thanks !

Okay thanks for that! I currently have a Panasonic freeview HD recorder that can record 2 programmes and watch a recording. So if I had a Vero, I was planning to get rid of that, otherwise too many boxes! So not really sure what to do at the moment.

Yeah, but like I did when I upgraded to this version from a terminal over SSH or inside the OSMC menu in Kodi?

/Söder

you can always use this to update to the latest version:

Run the following commands to update: sudo apt-get update && sudo apt-get dist-upgrade && reboot

Yeah, that what I did. Thanks.

Also great that devs fixed the problems (you all said, I haven’t tried myself) that fast.

Have you had a look at my issue @sam_nazarko?
I just updated and still the same issue it seems.

@sam_nazarko

I added below (only play from local devices) and now jelly fish plays fluently :nerd_face:

<advancedsettings>
    <cache>
       <buffermode>4</buffermode>
    </cache>
</advancedsettings>

I thought i just try this becauseI expected that Iperf3 was not an issue .

Updated and tried again. The contrast bug is still present.
