Over the last few nights, I finally got a MythTV box setup that I could use for some testing of the HVR-950q. I did some work a few months ago to basically get the analog support working, but there were some reports of problems related to switching back and forth between analog and digital mode…. Read More

Em28xx audio panic
I started working on the media controller stuff again, and was unfortunately sidetracked when I realized that any attempt to stream audio against my HVR-950 would cause the kernel to panic. Spent most of the evening chasing down the bug in the isoc handling code which would cause a page fault. Issued a PULL request… Read More
HVR-950q, em28xx GPIOs, and Dib0700 Firmware
Did some more testing of the HVR-950q under MythTV. Wrote some patches to get rid of a couple of spurious error messages. However, in the end the code currently in the v4l-dvb codebase today does work with MythTV, as long as you have the latest snapshot of 0.22, use the no_poweroff xc5000 modprobe option, and… Read More
HVR-950Q and MythTV: Now working….
After three nights of debugging various issues, I now have the analog side of the HVR-950Q working properly with MythTV. Special thanks go out to Janne Grunau for promptly merging my patch providing UYVY support to MythTV: http://svn.mythtv.org/trac/changeset/22343/trunk I will be setting up a tree this weekend with the 950q fixes. In the end, we… Read More
More fun with MythTV and the HVR-950q
Spent tonight continuing to debug the 950q under MythTV. I temporarily disabled the au8522’s power management, and the MythTV channel scanner started to see the channels, but it was otherwise behaving quite erratically. MythTV seemed to be trying to do a scan of both the ATSC side and the analog side at the same time,… Read More
HVR-950q analog / MythTV debugging
Now that I finally got a MythTV system setup again, I spent the evening doing some testing of the HVR-950q analog support. I was able to reproduce both issues that others reported, and have started to debug the problems. It seems like the big problem is that MythTV does a different sequence of V4L ioctls… Read More
Updates…
I was out of town for a few days last week, hence no updates during that period…. Fixes continue at a slow pace for the 950q analog support. A user pointed out problems with colorspace configuration when using the 950q with gstreamer. I spent most of Monday night debugging the issue, which I now believe… Read More
More minor fixes…
Still continuing to clear out my backlog of miscellaneous fixes. Added support for the K-World 2800d (thanks to Paul Thomas for loaning me the hardware and being so patient). While doing that work, I managed to uncover a minor bug in the em28xx audio code (the /dev/audio1 device file was being created even if the… Read More
HVR-950q and MythTV
As a result of a user’s complaint, I finally got some time to get a MythTV server setup so I can do some testing against the 950q. Indeed, there are definitely some problems. I’ve put together a patch for one issue already, and am continuing to debug. Hopefully over the next few days, I will… Read More
Xc5000 improvements Released!
