Hi Linux-media,
As a spare time project I bought myself a TT CT-3650, to see if I could get it working. Waling Dijkstra did write a IR& CI patch for this model half a year ago, so I was hopeful. (Reference: http://www.mail-archive.com/linux-media@xxxxxxxxxxxxxxx/msg19860.html )
Having tested the patch, the IR is working (tested all keys via the "evtest" tool), however descrambling is NOT working.
Waling's patch was reviewed but never merged. So I have taken the IR part of the patch, cleaned it up a little, and hopefully this part is ready for merging now. Patch is against linux-2.6.git.
Could you please rebase it to work with the rc_core support? I suspect that you
based it on a kernel older than .36, as the dvb_usb rc struct changed.
Ok, I have now done this, but I'm not completely satisfied, perhaps you
can help out a little? I'm new to IR/RC stuff, but I feel I'm missing
correct "repeat" functionality, i e, if you keep a key pressed it
appears as separate key presses with whatever interval set as
.rc_interval. (This was probably a problem with the old patch as well.)
Is there any support for this is rc_core?
I'm attaching a temporary patch (just for review) so you know what I'm
talking about.
The better is to base it over the latest V4L/DVB/RC development git, available at:
http://git.linuxtv.org/media_tree.git
Ok. I was probably confused with this entry:
http://linuxtv.org/news.php?entry=2010-01-19.mchehab
telling me to base it on v4l-dvb.git, which is not updated for four
months. However, http://git.linuxtv.org/ correctly lists the
media_tree.git as the repository of choice.
Thanks for the review!
