Audio stutter but only after file has played for ages

Kiboko · September 30, 2023 at 1:00 PM

Hi guys only recently installed Kodi onto my Raspberry PI P400.

I have noticed that on a number of occasions after playing a movie for An extended period, like 30 or 60mins the audio will start to stutter and lose sync. I think the times this has happened it has been on audio pass through on 1080p content. Any ideas?

Also I am struggling to play anything other than 720p on Disney plus. Even when I go to select quality 720 seems to be the highest quality. Do I need to enable something elsewhere?

Thanks for any help

Most of the legal streaming services require Widevine L1 certificates to display higher resolution content, and RPi boards are not "certified" hardware and thus can only see the content available to L3 devices (we fake a web browser). This is generally 720p HD although Netflix can often show 1080p content when available too.

Are you using adjust-refresh and a mode whitelist to change-to/use the native resolution/refresh of the media being played?

Many thanks for the reply

Ok that last bit lost me….so I would say I am not using that! So basically is it better to just use another streamer or the tv for these apps to get 4k? And just use Kodi for my video library ?

Have a read of this, it describes some of the main video setup things that help playback (even on TV's that are not 4K/HDR):

To get 4K on the streaming services requires a certified device like AppleTV, Google Chromecast, Amazon firestick, or a more general Android device like nVidia Shield. Linux devices are almost non-existent so an LE/Kodi combination is better with offline media and DVB. Personally I'm okay with 720p/1080p for services via Kodi due to better privacy in the OS and apps, but I understand others are more about specs.

I have done most of those suggestions but still have the issue.

To describe the issue more it is an audio stutter but also the video speeds and then slows down and repeats..

Seems the easy way to solve the issue is to switch off the Kodi box and reboot. So is potentially a cache issue?

Any other advice greatly appreciated

I'd suggest updating to a current LE12 nightly (which are quite stable to use) as a first move. Then if the issue is still present, share a sample (90-120 seconsds) from a media file that allows the issue to be recreated. Then pi devs can have a look.

Great thanks I will download a nightly build as suggested.

Thanks again for your help
