[libdv-dev] YUV output from PAL DV

[Christoph S. <ch...@ne...>]

Hello,

I tried to get YUV output from my PAL DV source but the picture I get is
scrambled and bright green.

The DV file was recorded with a Sony DVR-320E Digital-8 camcorder and
transferred using dvgrab. I used libdv-0.7 to decode the frames and I wrote
them in the YUV4MPEG format that is used by mpeg2enc from the MJPEG project
(on sourceforge). The resulting output is bright green and scrambled. When I
use dv2jpg (also on sourceforge) and go through MJPEG encoding in between,
everything looks fine. I looked at dv2jpg and noticed that it uses RGB
decoding from libdv.

When I use kino-0.4 to look at the file everything is o.k. as long as I don't
use Xv as output option. With Xv I get exactly the same wrong output (green,
scrambled). I took a look at the libdv-dev archive but all the messages I
found that related to YUV were from last year and it seemed that they were
fixed in the meantime. I have the impression the problem is related to YUV
decoding but I don't see what is going wrong.

Any help is appreciated,

Christoph
