Trouble with the Ceton InfiniTV 4 USB (TL__)

Post by 9072997 » Tue Sep 20, 2016 7:26 pm

Hello,

I have a Ceton InfiniTV 4 USB. I am also using a SDV adapter. I have
installed the userspace driver as well as the SDV driver from Ceton. I
can view TV by tuneing using the web interface, enabling RTP streaming
via the web interface, and viewing the stream with VLC (I have to set
a program number in vlc). Below is some information from the log:

MythTV gives TL__ Partial Lock when I attempt to watch tv (along with
a black screen). Any ideas would be much appreciated.

I have a Ceton Infinitv 6 ETH. After upgrading to 0.28 I got the tuner timeout intermittently. I fixed it by changing the timeout from 3000 to 5000 ms. Unfortunately that setting in not available in the setup screens for CETON, so I had to use SQL to set it. The following will increase the timeout from 3000 to 5000.

update capturecard set channel_timeout = 5000 where cardtype = 'CETON';

unfortunately that had no effect. I would assume that even if getting a channel lock was taking a long time, It would just warn me and then eventually start watching tv when I select "live tv" in mythfrontend.

I am attempting to work around this issue by writing an external tuner (black box) script which uses ceton's python client to get data from the device and send a single program via RTP, then uses mplayer to capture this stream and send it via stdout. So far I haven't got that working, but would settle for either solution.
