I have just upgraded to 0.25. Although it looks like myth has been compiled for cec support, it is not functional and I cannot find libcec.so anywhere in minimyth 0.25.0-80.
Should the library files be there or do you think there might be something else wrong with my setup?
Having getting it in the neck for taking so long doing the upgrade, I can't 'take ages playing with the TV' any more for today, though I should be able to fiddle with it later on in the week.
Did you get anywhere with this? CEC is really my reason to upgrade.
It does sound possible thought that the PC h/w doesn't do anything with the CEC line, and we could need to use the £30 USB-CEC adapter from pulse-eight.com...
I haven't had much time to look into the problem, work commitments and holidays have kept me too busy to get a dev environment sorted out so I can figure out what's happening.
Everything I've seen and been told on the MythTV side seems to expect it to 'just work' and unfortunately there's nothing much in the way of documentation to help figure out why it isn't.
Yes, it unfortunate that computer graphics cards with HDMI support do not appear to provide support for HDMI CEC.roundel wrote:Oh dear. Well it looks like I'll be investing in the pulse-eight hardware, and I'll post my success or lack thereof.
Firstly, I noticed that syslogd was stopping before mythfrontend starts, so after restarting that I was able to see some debugging information. Myth is able to see the device but fails to open it.
Aha! User minimyth does not have permission to read/write /dev/ttyACM0.
I fix the permission problem and restart X and .....
mythfrontend segfaults while trying to open the CEC device
I'm not sure if the following is any help :
Code: Select all
mythfrontend: segfault at c799c381 ip c799c381 sp bfb9729c error 5
I am using 0.25.2-81
I need to allow write permissions to /dev/ttyACM0 and /var/lock
If mythfrontend starts after those permissions are set it accepts input via HDMI-CEC
The bad news (for me) is that I've just got SkyTV and their box does not support CEC, meaning I have to stick with the Harmony remote I was trying to retire
MiniMyth 82 has the change.ac9bj wrote:Pablo,
What would one need to do to an existing 0.25.2 minimyth distro (PXE + NFS root) to apply the change you just made to ensure that /dev/ttyACM is writable?
