Tonight I finally finished the HVR-1600 ALSA cleanup and submitted what I hope is the final PULL request to get it into the mainline. While I was there, I took a quick look at how well tvtime works with the HVR-1600 – in short: it doesn’t work, and it fails in a way that I… Read More
hvr-1600
Making progress…
Things are moving along – last night I issued PULL requests for the em28xx PAL VBI support, as well as some cleanups for the HVR-1600 ALSA support that Mauro asked for. http://kernellabs.com/hg/~dheitmueller/em28xx-pal-vbi-2/ http://kernellabs.com/hg/~dheitmueller/hvr-1600-alsa-2/ I also checked in the patches I referred to last week when doing cx88 testing with tvtime (testing with a PCTV 800i)….

HVR-1600 ALSA Audio and Mplayer
There is now a tree that users are welcome to test which provides an ALSA interface for the HVR-1600: http://kernellabs.com/hg/~dheitmueller/hvr-1600-alsa-2 As was the case with the ClearQAM improvements, we have ONELAN Limited to thank for sponsoring this work. One thing that is interesting: as a result of wanting to do some testing, I noticed that… Read More
HVR-1600 Performance changes merged
Just a heads up to those who were kind enough to try out my testing tree for the HVR-1600 ClearQAM performance improvements: the fixes were merged into the mainline on Friday. So at some point you should stop using my private tree and switch back to the mainline v4l-dvb tree at: http://linuxtv.org/hg/v4l-dvb My tree will… Read More
Fun with HVR-1600 ALSA Audio
I spent some time this weekend dealing with various users of the “DVICO Dual Digital 4” who were seeing that zl10353 regression I have fixed on four other boards so far. I can say some choice words about the person who submitted the patch that caused the breakage, or the person who blindly accepted it… Read More
HVR-1600 ALSA audio and Performance Fixes
While Steven continues to churn away on ALSA audio and VBI support for the HVR-1800, I have started working on a project to do ALSA audio for the HVR-1600. So if you have an interest in being able to use the raw analog video capabilities for the 1600, stay tuned! The call for testers for… Read More
Call for Testers: HVR-1600 Improvements
If you are an HVR-1600 user who has noticed the ClearQAM tuning performance under Linux was worse than under Windows, this should make you happy. As a result of the work described in the previous post, there is now a tree that contains the various fixes: http://www.kernellabs.com/hg/~dheitmueller/hvr-1600-perf-2 The goal is to submit this upstream, but… Read More
HVR-1600 Performance and Reverse Engineering
Haven’t had much time to update the blog lately. All week I’ve been quietly grinding away at two basic issues: PAL VBI support for the em28xx chip, and identifying/addressing the HVR-1600 performance problem. I often get questions from users along the lines of “how do you make boards work?”. Reverse engineering is a bit of… Read More
