So that is that. I believe I may have changed the permissions... you mentioned that it may not have permission so I just went and chmod 755 everything even though xbmc runs as root.

[root@buildroot pvr.mythtv.cmyth]# pwd
/root/.xbmc/addons/pvr.mythtv.cmyth
[root@buildroot pvr.mythtv.cmyth]# ls -l
-rwxr-xr-x 1 root root 5423320 Feb 10 16:08 XBMC_MythTV_cmyth.pvr*
-rwxr-xr-x 1 root root 15116 Feb 10 16:08 addon.xml*

[root@buildroot pvr.mythtv.cmyth]#

there doesn't seem to be ldd on this image. I need to figure out where it went.

Hm that's really strange, so the file is there but it xbmc doesn't load it for some reason.
I asked for ldd because it could show you if the file is a correct shared library for your addon. objdump or any similar tool could work as well.

Does this XIOS distro that you are running have a support forum?
Could you try to ask them for help, especially how to build and install the xbmc-pvr-addons package.
Without knowing the platform I'm absolutely in the dark.

I can say for sure that it the addon itself works on arm linux. (tested a couple of weeks ago with openelec on the raspberry pi)

@richardk:
I have pushed a small fix to master and to debug-backend-cpu that adjusts all tcp rcv buffers to a bigger value (128000).

I was seeing a socket error: "writeStringList: Error, No data written on writeBlock" on the backend and I think I've seen a similar one also in a log you posted.
Janbar told me that this error message usually goes hand in hand with a high load on the backend.

Therefore it could be somehow related to your problem. It would be nice if you could retest (if possible with both branches).
How is your experience currently without images. Did it fix the issue for you?

Thanks,
Christian

This version of the addon worked for several hours. Then I got a box that said:

The PVR backend does not support this action Check the l...
An unexpected error occurred. Try again later or check the l...

I captured the log, and it's here:

So far, I have not been able to replicate this error.

My MythTV backend has now been up for over 2.5 days, with pretty heavy use. CPU usage when playing a video has not increased. It's still 1.5% - 6%.

I have made certain that the only XBMC instance accessing the backend is running the non-image version of the addon. Approximately the last day of usage included the socket error fix. So I cannot be completely sure which change corrected the problem, but it does seem to be gone.

Again, it would be great if other folks who have experienced the elevated mythbackend cpu usage could test the changes. It's always a little dangerous to draw firm conclusions from a single test.

Thanks. In the meantime I have fixed the error message that you've been seeing. I got it as well after playing a recording that was marked as watched.
Could you do me a favor and run the master code with images enabled. I'd like to know if the buffer fix might have solved the issue already.
If not, I have another idea and will come back to you as soon as I have some code to try.

Thanks a lot! Christian
