Captions/BTTV

["Michael Jackson" <mjackson@xxxxxxxxxxx>]

Hello, all.  I'm back.  :)

 

Here's an interesting issue.

My newest pet project is dealing with closed caption data.

 

I'm playing around with a bunch of avermedia PCI 350's that seem to work well for our purposes.

 

I'm messing with ntsc-cc to pull captions right now, called as "ntsc-cc -c"

 

What's interesting is that ntsc-cc will pull captions perfectly as long as XawTV is running.  As soon as I quit, the captions become "mangled," for lack of a better word - They become very nonsensical.

 

Example output:

 

BUILERE FAST.
UI
LA ARLYCENY
    ONERLI
    NTEQTY
    ADT
    TR99
'SCE
HENT

This is on kernel 2.6.10...  Using bttv, autodetecting the card.  Again, video and sound work beautifully (as long as I go from the audio out to the line in)

 

I'm just wondering what sort of initialization/uninitialization is happening here that makes the captions switch from "working" to "garbled."
