Dvico card (using the cx88 driver) isn't transitioning between analog and digital properly

Reported by: anonymous Owned by: danielk
Priority: minor Milestone: unknown
Component: mythtv Version: head
Severity: low Keywords: cx88 dvico analog digital transition
Cc: Ticket locked: no


I have a Dvico FusionHDTV5 Gold card that tunes analog and digital channels. It has no problems tuning analog and digital channels using mplayer. On mythtv, when you change the channel from a digital to an analog, it freezes up. If you start with a digital channel and press "C", it changes to analog and sometimes you can change the channel and sometimes not. After tuning to an analog channel and then attempting to tune back to a digital channel, it goes to fuzz and sometimes locks up and I can't recover from it unless I restart the backend.

Also when tuning analog channels, it doesn't look as clear as it does when tuning with mplayer.

This also happens on version 3 of this card, I bet this is a locking issue with the tuner resource, can't decide if the driver is the right place to "fix" this, or shared tuner usage in mythtv.

comment:4 Changed 15 years ago by paul@…

Note I have a DNTV Live pro DVB-T Hybrid card which has similar issues, when I switch between Composite and DVB-T devices, restarting backend seems to fix it mostly.

I'm going to need the driver version you are using + a "mythbackend -v record,channel" log using SVN head, not the 20-fixes branch.

Reopen the ticket after attaching the required info.

As requested, I am enclosing the information. I unmasked the gentoo mythtv ebuild which grabs the trunk. From the looks of it, it is rev 12945. I am using kernel version 2.6.20 which uses the 0.0.6 cx88 driver (Both analog and digital tune properly using mplayer). Here's the output information for the command you specified. I'm not sure why the version number is 0.20 but I'm guessing that just hasn't been updated.

I'd also like to add that at this point I am completely unable to tune analog channels. I am sure I have set up this hybrid card properly. It's a digital card with analog options set up so that it is one dvb card (DVB DTV Capture Card) with television input (analog option) set as the second part using the v4l2 driver and the analog part is detected with the correct driver (cx8800). On previous versions of myth, I set the digital and analog portions up as separate cards but as I understand that should no longer be necessary nor should it be since I'm sure it would cause recording issues. It tunes the digital channels properly and it always defaults to digital when I select watch tv. When I press "C" or try to switch to an analog channel, it just freezes up now. When I try to switch to an analog channel after I'm initially tuned into a digital channel, it shows me this text: You should have gotten a channel lock by now. You can continue to wait for a signal, or you can change the channels with Up or Down, change input's (C), capture cards (Y), etc.

Matt, please retest using SVN head, not the Gentoo fork.

Also, I'm going to need you start LiveTV, wait for the digital channel to come in, then tune to the analog channel (just type in the channel number of an analog channel). Even if it fails to tune the "mythbackend -v channel,record,siparser" log will tell me a lot about what is going on. Please attach the entire log as a file, don't put it in the ticket comment.

If you can attach the dmesg output this will tell me if the driver is complaining about something.

I'm pretty sure there isn't much if any patching involved in the versions I'm using now:

*mythtv-0.21_pre12945 (19 Mar 2007)

19 Mar 2007; Doug Goldstein <cardoe@…> +mythtv-0.21_pre12945.ebuild: Added a SVN trunk ebuild (svn revision 12945) to test out the new capability of the eclass to support such ebuilds

I was using this version: 0.21_pre13285

I uninstalled that version and just did a checkout of trunk which is 13551. It looks like trunk mythtv is broken because I am unable to compile it. I am attaching the log and what I did.

Is this going to be enough information now? I have been wanting to get both analog and digital tuning on this card working on mythtv for years now, I'd really like to see this work. Currently I have no problems using mplayer to tune analog and digital. Mythtv is able to tune digital fine but is completely unable to tune analog now with this card on kernel 2.6.20.

comment:12 Changed 14 years ago by mattsch@…

Still locks up when switching from digital to analog in the latest svn version.

Looks like a setup problem with channel sources. Sorry to take so long to look at this. :|

This code has been changed for multirec, it may or may not be fixed, but the logs would need to be recreated and attached to #2617 if there is still a problem.
