Remote isn't responding during playback V35

[justinh]

I recently updated Ubuntu to 24.04 which brought MythTV up to V34. All good but I saw there was a new release so added the MythBuntu PPA & installed V35. All works great except the lirc remote now does nothing during any video media playback. Lirc seems to work just fine & is reporting button presses as it should (checking with irw).

Any ideas as to what might be wrong? My first port of call was Wayland, so I disabled that (though gnome seems to be broken but mythfrontend starts as a service as expected still so I'm not really concerned about that). Even with Wayland out of the loop I'm not getting any lirc buttons to work. If I connect via a remote desktop connection or use a USB keyboard, keypresses work just fine.

I think I have the same problem: https://lists.mythtv.org/pipermail/myth ... 15036.html
Unfortunately, I haven't had time to try and debug it further.

I managed to downgrade to the previous version of mythtv, had exactly the same problem. So then I grabbed a spare SSD I had lying around, installed a fresh copy of 24.10 onto it, then mythtv, lirc etc, restored a database backup of the working V34 system - and it's fine. I'm sticking with this for now.

updated Ubuntu to 24.04

I do a fresh install instead of upgrading when installing Ubuntu.

If the remote and IR receiver are compatible with ir-keytable, try that. I use MCP when setting up my remote. I have not tested this myself with Ubuntu 24.04 and v35, but I am currently building a new backend box and will be doing this soon.

FWIW, I have the exact same issues as the others in this thread.

I upgraded my back-end server from Ubuntu v20 to v22, then to v24.
I was then able to go from Mythtv v31 to v35. Yeah!
(my back-end is a VM, so snaps are easy.)

The front-ends are giving me fits. Ubuntu upgrades went smoothish and Mythtv upgraded to v35 OK.
My remotes show correctly in IRW and ircat. They work perfectly in the front-end menus.
But, they DO NOT work in TV playback or Movie playback (using the internal player.)

Also, irexec broke along the way, but I managed to fix that at the systemd + config file level.

An interesting tidbit I just found:
When navigating the front-end menus, I can use "volume up" on my remote to irblast to my tuner. Works perfectly.
When watching a movie, this stops working.
Exiting the movie via keyboard, irexec/blaster starts working again.


So, I agree, seems like a v35 bug at this point. Anything I can do to help? (I am not a coder, but I can troubleshoot and test!)

Thanks!

I don't use a remote, but if I did I'd use a non-mythtv tool to see what the remote keys such as UP are returning, then I'd check the frontend keymaps. IIRC, there's different key maps for the menus ("General"???) and playback, etc.

If you could still test this with u20/v31 or some other combination (specifically NOT u24 and v35 together) it would probably be helpful to know what changes and where.

irw etc still report the button presses. It's as if mythtv's internal player just isn't listening to lirc anymore.

My lircrc worked fine with everything before v35 & it only has the main keymaps setup. Esc is mapped to the STOP & EXIT buttons on my remote so this *should* stop playback no matter what. It doesn't

I can also confirm that irw still reports the button presses while video is being played.
Same as Justin; it is like mythtv is not listening using the internal players.

I cannot test the older mythtv versions, I already upgraded to v35 on the backend and my 2 frontends. (I was not able to get to v35 on Ubuntu v20, that was my driver to upgrade to v22 and v24)

I think I found what change caused it to break. I've reported it here: https://github.com/MythTV/mythtv/issues/1064

I have not tested this myself with Ubuntu 24.04 and v35, but I am currently building a new backend box and will be doing this soon.

For those who want to use the ir-keytable method, it appears to be working as expected. I installed v35 on my new backend box with Ubuntu 24.04. I installed ir-keytable using MCP, and I used the remote to navigate the menu and play, pause, fast forward, etc. using a video in the video library.
