[linux-dvb] grabbing with transcode...

[skrodzki_list@stevekist.de (Stephan Skrodzki)]

Howdy,

I took the CVS of today and build it against a vanilla 2.4.24

I'd like to grab with transcode (don't ask me for the deep sense of doing 
this, but it is a kind of filtering I have to do, and the Real Producer - 
which I have not decided to use - has the same problems) with the following 
line:

transcode -i /dev/video -o mytest.mpg -x v4l -y raw

transcode segfaults, in syslog I find the following (see below...)

I suppose it is a matter of a not 100% working v4l1 compat mode, am I wrong or 
is there anything I can do there?
