According to google, installs are normally done by first switching to
the user id '_apt'. Since _apt doesn't have permission to read files in
your home directory, the install ran as the user root. The message is
harmless. You could get rid of it by giving _apt access to your build
directory, or by copying the files to /tmp before installing them.

I'm awed by your superior googling skills. :-)
So the safe method seems to be moving the debs files to /tmp and then doing
the install.

Thanks for the help.

Hi Jim,


* The code works on my RPI4 4GB as well as it normally does, which is not acceptable to me. But I wanted to get at least one version of fixes/34 posted for those who could not build it themselves.

Could you recap what makes fixes/34 not acceptable on your raspi?
My experience on current RaspiOs Bookworm

Pi5:

* X11
* Remove /etc/xdg/autostart/xcompmgr.desktop

Pi4:

* Even without xcompmgr, I still get tearing in X11 so
* Wayland only works reasonably with the color space patch from https://github.com/MythTV/mythtv/issues/855; without that mythtv uses an RGB 6:5:6 (16 bit) Surface with terrible color reproduction and very visible banding
* Hiding Mouse cursor requires wayfire plugin hide-cursor from https://github.com/WayfireWM/wayfire-plugins-extra
* Unresolved: Can’t get wakeup from DPMS to work when using a lirc based remote

Except for the wakeup from screen blanking issue, I find no issues with playback up to and including h.264 1080p50 (I haven’t tried 1080p60)

Bye, Martin

When I worked, I spent too much time trying to help customers get our low
powered CPU and GFX to provide the video they needed/wanted. So I looked
at a lot of crappy video performance and became overly sensitive to jittery
video, frame rate problems, lip-sync issues, etc, etc.

I've wasted too much time trying to get the RPI 4 to run mythfrontend to
my satisfaction. It's not too far off, but since I have a FireTV 4K on
every TV I own, I use that because the FireTV 4K is far superior to the RPI
4 in every way. mythfrontend is pretty good on the FireTV 4K and Leanfront
is perfect. Leanfront has a better picture than I can get on my Intel NUC
1165G7. Also the FireTV 4K Max I use on both our UHD 4K TV takes the
1080i/720P MPEG2 HD over the air programs and improves them a lot. The RPI
4 can't do that.

So I'm not wasting any more money on RPI 4/5 for Mythtv projects. Maybe
for a remote backend for my FireTVs. But since I like commercial flagging,
you need more than a raspberry PI.

To satisfy my curiosity, I built mythtv-light on a fresh RPI OS 64 bit
system and after the build I copied the .deb to /tmp/ and then installed
with:
sudo apt install /tmp/mythtv-light.....deb
That worked without warning or comment.

Thanks, again.
