Re: pi-utils/pi-setup_mythtv_31.sh

In testing pi-setup_mythtv_v31.sh I've found it works great on the standard PI OS Desktop version. If you want to start with PI OS Lite, you would need to add the following to the script: sudo apt install --no-install-recommends xserver-xorg This may not affect many, but I found this out in testing...

Re: Can't get backend up and running

I just installed from scratch Mythtv v31 on a fresh Ubuntu 20.04 system. I documented what I did so I can repeat it because next year when I need to know I will have forgotten. You may find some useful tidbits in the post. There is a lot of my specific needs, but you can ignore them. If you don't ha...

Re: RPi 4 MythTV-light 31 issues

Well, I'm confused about the need for a compositor. Here's what I did after MikeB updated his scripts yesterday. 1. Fresh install of Raspberry Pi OS and did a fully upgrade. rebooted 2. Clone the latest pi-utils from github. https://github.com/MikeB2013/pi-utils 3. run "pi-utils/pi-setup_mythtv_31.s...

Re: RPi 4 MythTV-light 31 issues

FWIW I'm seeing the same problem as of doing an update last night. Might have to try the kernel downgrade. EDIT: Downgrade of kernel as per the link posted above "worked" in that the image was fixed, but audio was lost. EDIT2: Re-upgraded, enabled the compositor, sound and video now working. So I r...

Re: RPi 4 MythTV-light 31 issues

okay that worked for me also and the playback is most likely a config issue. on video playback set profile to MMAL, standard, opengl, CPU=4, Low quality. I think you'll get it from there.

Re: RPi 4 MythTV-light 31 issues

looks like we are chasing the same issue. I just burned a new microSD with raspberry pi OS and booted it, updated it and then cloned the pi-utils. Then I installed mythtv-light using pi-setup_mythtv_31.sh After the install I rebooted. When I run "./run_mythfrontend" mine gets to the Could not queue ...

Re: RPi 4 MythTV-light 31 issues

I get that error when I run mythfrontend without using the startup script, but when I use the startup script, it just exits after trying to ping the display's EDID: Here is a transcript of stdout and stderr when trying to use the startup script: The part that worries me the most is this: drmModeGet...

Re: RPi 4 MythTV-light 31 issues

The segfault is while trying to start mythfontend, not after exiting. It won't even start up. Do you get this error message while the frontend is trying to start up and before the Seg Fault?? Could not queue DRM page flip on screen HDMI1 (Invalid argument) I get about 4 or 5 of them in a row. I jus...

Re: RPi 4 MythTV-light 31 issues

I just tried setting the frontend up without a desktop environment, using the MikeB scripts, starting with a fresh OS install. It looks like it tries to start up after a reboot, but I get a seg-fault on line 103 of the run_mythfrontend.sh script. If everything is going normally, you will get a seg ...

Re: RPi 4 MythTV-light 31 issues

Well, I've been experimenting with the RPi4 and mythtv for a long time. While it makes a good backend, I have yet to tolerate watching it as a frontend. On action content it has issues. Maybe now that Raspberry Pi OS has moved to the Linux 5.4 kernel we will see some fixes. However, based on you men...

Re: creating a RPi slave/remote backend?

Okay, I got some help over on the mythtv user mailing list. I thought I'd document what I did. 1. Fresh install or Raspberry Pi OS Desktop on RPi4 4GB 2. Setup repository and install mythty light per: https://www.mythtv.org/wiki/MythTV_Light#Repository_Setup 3. Install pi-utils per: https://github.c...

Re: RP4 Boot from USB3 for mythbackend

There have been a lot of updates lately. Not sure what got fixed. I know if you look at dmesg you see a lot of sd card errors when it's not there, but it still boots from USB. The key is to have the right USB device. I use a ASMedia enabled USB3 to SATA adapter from both Eluteng and StarTech. I've t...

creating a RPi slave/remote backend?

I have a mythtv v31 remote backend on Ubuntu Server 18.04 with a PCIe tuner card and mariadb-server instead of mysql. I thought I'd create a slave backend using a Raspberry Pi 4 4GB and a HDHomerun Quatro. I have installed mythtv v31 on a RPi4 and used it as a combo and as just a remote backend. So ...

Re: New build - help needed - separating combined BE/FE

On the RPi4 I have found no issues running it as a backend only with a HDHomeRun Quatro. So I've tested recording 4 shows at once during primetime so there might have been a 1 minute or so of overlap where it's really recording more. I have the multi-record to 2 recordings per tuner, i.e. 8 possible...
