No HW accel on Kodi-20

[kabutor]

I just updated archarm and found out that I have no HW accel on Kodi, not with the x264 or x265, I press O while playing and I see the ff-h264 (SW) flag.

I tried downgrading the kernel to
6.1.42-1-rpi-ARCH #1 SMP Thu Jul 27 11:54:50 MDT 2023 armv7l GNU/Linux
but I have the same results than with latest linux-rpi-6.1.45-1
Some info:

Been trying several things, nothing seems to do anything (I have the default config.txt and kodi.config.txt on boot also)

[graysky]

You have to modify /boot/config.txt and reboot.

', 'https://github.com/archlinuxarm/PKGBUILDs/blob/master/alarm/kodi-rpi/kodi.install#L4-L11', '', ' class="postlink"')

[kabutor]

Oh, yes sorry, when I said that I have the config.txt as default, I mean I just put the new files on the package, but I included the [all] lines, but still no hw accel.

I am getting the same. Need to debug. Thanks for reporting. Do you know when you had a last-known-good set of packages?

[kabutor]

I'm sorry I don't know the exact date, I installed the mosquitto broker a week ago and I had to update the whole system, I guess it was from there. EDIT: I don't do frequents updates on this, maybe last update befora that was 2-3 months ago)
I realized this morning playing a x265 old movie I had on the drive that the playback was very choppy, and it's a movie I've watched before without problems, doing some tests I saw that it was not only on the x265, but in x264 as well.

Thanks for the help.

I am thinking this is not due to the kernel but to something in the kodi codebase. Why: hw-accell on ffmpeg-rpi works just fine. Continuing to dig.

[unformatted]

I recently upgraded kodi-rpi on RPi4 aarch64 which hasn't been upgraded since March and also had no HW acceleration.

Under Settings > Player > Videos I noticed "Allow using DRM PRIME decoder" had been turned off. After turning on everything was fine. I also noticed a new setting "Allow hardware deinterlace with DRM PRIME" has beed added but that does not work on my setup.

Perhaps because of this new setting has been added, HW acceleration has been turned off.

[graysky]

Good find! Upstream dropped usr/share/kodi/system/settings/appliance.xml which set this automatically. I need to wait for the new build for spdlog (1.12) to get updated in order to build due to incompatibilities with the fmt-10.1.0. Once that happens, I will fix in our packages.

[kabutor]

Yes, that fixed it, good find.

Thanks again
