All,
Thanks for all details… and it helped me to get HW transcoding up and running on N5105 running Debian 11.3 with OMV6.
Its not straight forward… but want to give highlights if some one else is looking for details.
- Update Kernel from Debian backports - Updated it to 5.16. This is not stable version
- Update FFMPEG to v5 - This is not stable version again
- Update I915 firmware files and run update-initramfs -u
And then HW transcoding started working… Except when you have HDR10 video, it works fine and my CPU usuage is around 30-40% even when transcoding multiple 4k files.
