Gerd Knorr replied to Florian Zierer:
is there a way to get alevt (or another teletext program) running
with saa7134?
I've seen patches for alevt, but don't rememeber where (maybe this
list?)
alevt-1.6.1 still uses the old vl42 API and hence does not work with
current saa7134 drivers. I made a patch for it already in January
which also contained a work-around for the swapped fields bug in
saa7134. I've updated it for saa7134-0.2.7, it's still located at:
http://nxtvepg.sourceforge.net/tmp/alevt-1.6.1.diff
But maybe it'd be better for alevt to use v4l1 ioctl VIDIOCGVBIFMT
anyways, since it's currently more widely supported and wouldn't
risk incompatibilities by including parts of videodev2.h within
the sources (alevt doesn't use v4l2 anywhere else except to query
VBI parameters)
libzvbi 0.2.4 does just fine, and everything working on top of that
should work too. (...)
I don't know about these apps, but when I tried to use libzvbi with
saa7134 I had a few problems, e.g due to lack of VIDIOC_S_FMT for VBI
and wrong line number indices returned by VIDIOC_G_FMT. I plan to
send you a patch for these and some issues with bttv-0.9.9 soon.
