Update from OE to LE now DVD rips no longer play

Hello

Are there known issues with DVD (MPEG2) playback in Kodi V17 / LibreElec ?

I am running a HTPC and since updating from OpenElec 6.0.3 Kodi V15.2 Isengard to LibreElec 8.0.0 (LibreELEC-Generic.x86_64-8.0.0) I can no longer play DVD rips properly either VIDEO_TS or ISO rips, when hardware acceleration is turned on.

The HTPC either freezes the video playback but the audio is still heard or it crashes out of Kodi and restarts.

Motherboard - Intel DH67CF
CPU – Intel 2nd Generation Core i3-2100

I can play Blu-ray ISO rips perfectly fine however, streamed over the local gigabit cabled LAN.

If in the Kodi settings I go to Player -> Videos and disable "Allow Hardware acceleration - VAAPI" then the DVD rips play OK without problems.

Thanks

we can't do anything without a proper debug log.

Hello try this one...
Intel VAAPI howto with Krypton v17 based on Ubuntu 16.04 server

Quote

System ->Video->Acceleration:
Enable HQ Scalers for scaling above: 20%
Allow hardware acceleration (VDPAU): off
Allow hardware acceleration (VAAPI): On
Use Mpeg-2 VAAPI: Yes
Use Mpeg-4 VAAPI: if you like
UseVC-1 VAAPI: on
Prefer VAAPI Render Method: on <- This version has the banding fixed, so enable that setting to save CPU cycles with 100% quality.
Adjust Refreshrate to match video: On

System -> Video -> Playback
Sync Playback to Display: On if you don't use passthrough and Off if passthrough enabled (* This makes no sense when you want to use passthrough, why? Read: Kodi Community Forum). In current versions (Jarvis) passthrough is disabled by us if users wants to Sync Playback to Display to care for people that refuse to read.
Adjust display refresh rate to match video: On Start / Stop

While watching a SD(!) video, that is accelerated by VAAPI, e.g. mpeg-2 or h264, click the film role and choose: Deinterlace: Auto (Never set this to ON it will harm for everything that is not interlaced) Deinterlacing-Method: VAAPI-MCDI or VAAPI-MADI (Sandybridge) and VAAPI-BOB (BYT), Scaling Method: Lanczos3 Optimized and choose save for all files. Remember to do this only in combination with the above "scaling above" for 20%. This Lanczos3 Optimized filter is too heavy for BYTs, here you might - depending on the file - choose Bilinear.

It is obviously clear, that you won't see the VAAPI-MCDI settings when you play a video that is software accelerated only.

Hi

I changed a few settings:

Was set as Off - Adjust display refresh rate to match video: On Start / Stop
Was set as Bilinear - Scaling Method: Lanczos3 Optimized

Deinterlace: Auto (I don't appear to have an Auto option. Its currently set to VAAPI-BOB)

All the other settings were correct.

Tried playing a few DVD disc rips and its using Hardware Acceleration and its not freezed up as yet, I will monitor.

Thanks.
