Been a few days since I’ve posted an update. Here’s a brief summary of things that have been going on in the last week:
Progress continued on improving em28xx analog quality. I isolated a problem with chroma AGC in the saa7115, and am working on a fix now.
I nailed down most of the analog problems being reported against the HVR-950q under MythTV. Posted a tree with fixes and solicited testers to try it out before submitting it upstream.
I finally plugged in my HVR-1800 and took a quick look at the analog support situation under MythTV. It falls down pretty hard with the current v4l-dvb tip, but the situation is somewhat improved with some patches Michael did a few months back which haven’t yet made it into the mainline. Nonetheless, it still would need quite a bit more work before I would consider counting on using it in a MythTV box (looks like a couple of race conditions which will be annoying and time consuming to isolate). Also, a number of the controls are still not implemented, which cause some “red herring” error messages in the MythTV backend log file. I’ll probably also have to plug in a PVR-150 card so I can better understand how the driver capabilities should be announced (comparing the ivtv driver against the cx23885 analog support).
So, things are moving along….
