Hello,

I'm experiencing an issue of video smoothness since upgrading Kodi from v18 to v19.
I'm using Kodi with LibreElec installed on a Pi4 for the v19, Pi3 for the v18. My videos are stored on a NAS.
All my videos are mkv files, 1080x1440 pixels, 25 fps, MBAFF interlaced (recorded from French TV - by the way English is a second language for me).

On both versions, in Settings/Player/Videos/Playback, I have :
- Adjust display refresh rate : start/stop
- Sync playback to display
In v18 I have also Rendering:
- Material acceleration : OMXPlayer + MMAL
No such option in v19.

The In-playback video settings :
- Deinterlace method => auto in v18, deinterlace in v19.
In v19 I have also Video scaling method => closest.

Videos are smooth in v18, jerky in v19 (so I must stick to v18).

Lots of ffmpeg errors at the end of the v19 log (when watching a video) : https://paste.kodi.tv/ugipekajud.kodi
(I haven't these errors in the v18 log).

Thank you for reading me, if you have any ideas to sort this out...

I wonder if it's a problem of hardware acceleration.
The CPU usage during a video play is about 300% with v19/Pi4 (4 CPUs), only 20% in v18/Pi3 (4 CPUs too).
Is there a way to enable hardware acceleration in Kodi 19 on a Pi4 ?
