kaufhauslicht 3 Posted July 21, 2017 Share Posted July 21, 2017 (edited) Hi, I compiled my own ffmpeg build in order to use vaapi acceleration. It is working fine when I am transcoding without any scaling (e.g. from 1080p 30MBit to 1080p 5Mbit). However, when I change the resolution (e.g. from 1080p 30MBit to 480p 1Mbit) the scaling is off and I only see the top left segment of the original picture (see "down scaling 480p.png and "org scaling 1080p.png). Without vaapi acceleration the scaling works fine. I am running emby on Openmediavault 3.0.84 with Intel HD Graphics P4600 (Dell T20), as you can see in the server log (Log.txt) attached. So, what could be the problem? I would be delighted if you guys could help me. Thanks, kaufhauslicht Log.txt transcode_log_480p.txt transcode_log_1080p.txt Edited July 21, 2017 by kaufhauslicht Link to comment Share on other sites More sharing options...
puithove 208 Posted July 21, 2017 Share Posted July 21, 2017 No issues here. You may want to update your libva and / or video driver. Link to comment Share on other sites More sharing options...
kaufhauslicht 3 Posted July 21, 2017 Author Share Posted July 21, 2017 Hey puithove, thanks for your support. Libva and the intel i965 drivers are rather old in the official debian repo. Therefore, I installed both of them directly from intel. Now it is working. Thank you! 1 Link to comment Share on other sites More sharing options...
