On a Raspi 3B+ that I am preparing for MythTV (sofar it works fairly well), I'm trying to verify that the license for hardware MPEG2 decoding has been installed correctly - according to the mail from the Raspberry Pi Store, the command is: vcgencmd codec_enabled MPG2 I guess this is a Raspbian specialty - does anyone know where to find "vcgencmd" for openSUSE ? I see it here, but it's a 32bit executable, I guess I need some 32bit stuff for it to run? https://github.com/raspberrypi/firmware/blob/master/opt/vc/bin/vcgencmd thanks Per -- Per Jessen, Zürich (4.0°C) member, openSUSE Heroes. -- To unsubscribe, e-mail: opensuse-arm+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-arm+owner@opensuse.org

Last time I tried, the multimedia stuff worked only on raspbian kernels anyway and only on 32bit. The userspace stuff was not even compiling under 64 bits (or all functions would be #ifdef'd to dummys or something like that, I don't remember exactly).

There is also source code in the userland package IIRC, I built this from source on my yocto poky build some years ago at least. -- Stefan Seyfried "For a successful technology, reality must take precedence over public relations, for nature cannot be fooled." -- Richard Feynman -- To unsubscribe, e-mail: opensuse-arm+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-arm+owner@opensuse.org

It is available in raspberrypi-userland package available for Tumbleweed here: https://download.opensuse.org/repositories/devel:/ARM:/Factory:/Contrib:/Ras... But it fails to build since end of September, so not sure if it is still installable. But last time I tried, video decoding seemed to happen (no error) but no image from the video were shown on HDMI output, only a black screen. Cheers, Guillaume

Hmm, doesn't sound too promising. Thanks, I'll have a look.

I have TV working, that was straight forward, but it's definitely not hardware accelerated. I have added the following to /boot/efi/extraconfig.txt : hdmi_force_hotplug=1 decode_MPG2=0x12345678 -- Per Jessen, Zürich (3.9°C) -- To unsubscribe, e-mail: opensuse-arm+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-arm+owner@opensuse.org

Try with a HD channel (h264), that needs no extra license. But as I wrote, I could not get any of the video acceleration things going with openSUSE kernels (I think I tried on the raspi 3, this is when I noticed that the userland stuff will only build for 32bits) -- Stefan Seyfried "For a successful technology, reality must take precedence over public relations, for nature cannot be fooled." -- Richard Feynman -- To unsubscribe, e-mail: opensuse-arm+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-arm+owner@opensuse.org

Have just tried "Channel 4 HD", it reports HD1080, H264 - but it stutters, it is not watchable. Clearly not accelerated which is weird?

Okay - I guess it isn't so important, it was just a way of checking. -- Per Jessen, Zürich (4.4°C) http://www.hostsuisse.com/ - dedicated server rental in Switzerland. -- To unsubscribe, e-mail: opensuse-arm+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-arm+owner@opensuse.org

AFAIK, only omxplayer was using video acceleration. https://pmbs.links2linux.de/package/show/Multimedia/omxplayer Cheers, Guillaume

Were you ever able to use omxplayer on 64bit openSUSE raspi3? -- Stefan Seyfried "For a successful technology, reality must take precedence over public relations, for nature cannot be fooled." -- Richard Feynman -- To unsubscribe, e-mail: opensuse-arm+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-arm+owner@opensuse.org

I had a look at it just now - I don't see any builds for Leap 15. -- Per Jessen, Zürich (4.9°C) -- To unsubscribe, e-mail: opensuse-arm+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-arm+owner@opensuse.org

Hmm. According to the MythTV wiki, it will use hw acceleration if available, e.g. VDPAU (Nvidia) and the Intel VAAPI - does not mention the Raspberry of course. Ah, I think need to change the "Painter" setting to Auto. Hmm, did not work very well - maybe if I run MythTV directly, instead of under icewm.

Just a brief conclusion - I kept getting conflicting reports about the Raspi's ability to run MythTV with HDTV in a satisfactory manner. My own brief experience showed it was _slow_ just operating the MythTV menus, which I could tell was going to annoy me. Instead I switched to a Zotac mini PC I bought 3 years ago. Back then I gave up because I could not get hw accelerated video to work with Intel HD graphics. Seems to work fine now on Leap 15.1. -- Per Jessen, Zürich (11.3°C) -- To unsubscribe, e-mail: opensuse-arm+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-arm+owner@opensuse.org
