You also have to specify -d /dev/video1 when querying with -X. Can you try
again? I looked at the 0.2.0-rc3k source and it should work. You should also
use the ivtvctl from the same version as the driver (if you weren't doing
that already).
I just had copied the wrong lines. There was a recording on video0, and i
queried both cards with the same results, then set video1 to -x 0 and
there was no difference. With 0.2.0 both would ever say "vbi embedded in
MPEG stream: on". The tools' version was always the same as the driver's
version.
But with 0.3.8 it looks like this:
--->
pvr:/usr/src/testing/utils$ ./ivtvctl -X
ioctl IVTV_IOC_G_VBI_EMBED ok
vbi embedded in MPEG stream: off
<---
Anyway, these tests should be done without using embedded VBI. If the dropouts
happen only with embedded VBI then that would of course be a strong
indication of were to look.
If the output of 0.2.0 is right and for whatever reason vbi embedding is
always on for 0.2.0, then it is just the other way round: No drop outs
with vbi and probs without it.
Is there a chance to check for vbi data in the mpeg stream? Mplayer
won't show any difference with vbi data turned on (just tested that with
0.3.8).
