I've made a new release (available from www.xs4all.nl/~hverkuil until added
to the regular archive).
This one might be less stable than 0.3.7g since I've added sliced VBI for
the PVR150/500/PG600 cards, and it hasn't been tested very well. Especially
NTSC is basically untested.
First the Changelog:
#0.3.7h - add a function to decode a VBI line to the decoders
- fix raw VBI for NTSC (the end of the CC lines contained garbage).
- enable stricter sliced VBI matching to prevent WSS or VPS from being
seen as teletext.
- fix division by zero when choosing a width > 720.
- improve tveeprom: now reports the audio processor correctly, and it
also shows the decoder processor.
- fix ivtvctl: register addresses were mangled by a 'char' cast.
- add sliced VBI support for the cx24850.
- remove cardtype from cx24850. Now the ivtv driver sets the cardtype
automatically.
Sliced VBI support allows you to store closed caption data (NTSC) or teletext,
VPS and the Widescreen signal (PAL) in the MPEG file for later processing.
See ivtvctl options -b, -x and -w.
Some known issues with this implementation for the cx24850 are:
- Supporting WSS for both the saa7115 and the cx24850 meant that the format
had to change. So existing recordings with the WSS signal will no longer
be understood (w.r.t. the WSS signal) by the new driver. Of course, the
file can still be played, it's only that the embedded WSS signal is no
longer used.
- VPS support seems flaky: the channel name seems to rotate randomly, somehow.
- CC and NTSC in general is not tested at all.
- PAL line 334 is never present, even though it contains teletext.
How to test? Choose a channel with teletext (PAL) or CC (NTSC), then run
the 'vbi' tool from the test directory. You may have to add the correct device
name (e.g. 'vbi /dev/vbi1'). You should now see VBI data going past.
I'm curious to see the results on NYSC...
Enjoy!
Hans
