A PULL request was issued to the linux-media mailing list tonight for the NTSC closed captioning support:
So if you have a em2880 based device such as the Haupauge HVR-950, a PCTV HD Pro 800e, ATI TV Wonder 600 USB, or any of the em2860 based devices such as the KWorld 2800d, then you now magically have closed captioning support!
The raw VBI support is currently specific to NTSC, but PAL support will come soon. The work also exposed some bugs in zvbi, as well as prompted me to realize that tvtime’s closed captioning support is completely broken if your VBI capture buffer width doesn’t happen to be 2048. Now that I actually have the VBI support working on one of my cards, I’m hoping to go back and do some fixes on the userland apps.
Special thanks go out to EyeMagnet Limited for sponsoring this work.
