Vero 4k+ Playback Issues

Help and Support Vero 4K / Vero 4K +
1

Hi, after running my Vero 4k+ on Kodi 18.9 until last month I finally decided to upgrade to 19.3, following the upgrade I started having playback issues with multiple files, in each instance the audio was fine but the video was either black or lurched between stills approximately 5 seconds apart. At the time I gave up and rolled back to 18.9 where all was once again good. Yesterday I tried again with the 19.4 March release and am experiencing the same issues. The Vero is connected via a Sony AVR but fault exists when connected directly to the TV which is an LG 756Nano series, 4.2.2. pulldown is enabled in Kodi as per recommendation for LG TVs.

Media info for file with black screen:

The same files play flawlessly when the Vero is replaced by my Pi4 Media Player running the same version of OSMC.

The fault occurs with all UHD/4k content i’ve tried and some 1080p (can’t locate an example at the minute)

After years of rock solid performance this is driving me insane now and just want to get back to it working without having to downgrade again

Thanks

Good to know that this issue still exists after the latest update.
I think it’s the same one as reported here:

The changelog didn’t mention anything specific to this issue except for this:

In the background, we’re laying the groundwork for a number of other changes which will be released in the near future, including improvements to video playback for Vero 4K/4K+

So there is still hope.

In the meantime, cold rebooting helps.

Thanks, interesting read! Unfortunately cold or warm rebooting doesn’t make any difference, I have 100% failure rate with these files playing back. What I didn’t see on the other thread was any reference to no video at all, just stuttering.

I’ve sent you some details with a possible solution.

Thanks, the suggested temp solution works as expected

Thanks for confirming Chris.

I am also seeing this behaviour, although it’s only dropped frames. Is a reinstall of the OSMC then suggested remedy?

After updating to 19.4, the video started to stutter. Before the update everything was fine. I fixed the problem by disabling HW acceleration. The details of the video I’m watching the problem with are:

There is no problem with other videos.

Hello,
can you or Sam explain what the suggested solution is exactly ?
Thanks in advance, current HEVC stutterring is really a pain …

There’s a non-standard SD/USB image to run from until the issue is fixed in the normal release, Sam need to add you to the group to access though

Thank you for the answer, that is a good news that a fix exists already and coming !

@sam_nazarko, I’ll leave to you to include me in the test if this can help!

Otherwise I will just wait for the next official release, hopefully it comes very soon
