RE: Interlace Noise (field swapping?) on Pinnacle PCTV

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]



I'm talking about motion capture.  I have two goals.  1) Make a PVR, and
2) Be able to pull a stream off my video server from another computer.
If I'm successful with 1, I should be able to swing #2.

I tried mp1e with the following settings:
mp1e -m 1 -c /dev/v4l2/capture0 -C k7 > test4.avi  

The video output I got is here:
http://gate.takeflight.ca:8079/test4.avi

It's a short clip, but you can clearly see these lines, even with mpeg1
encoding..  Can anyone compare this to thier results, and let me know if
this is typical?

Regards,
Patrick

I have the Pinnacle PCTV PRO.  Are you talking about still capture or
motion capture?  For me xawtv is fine if I don't specify the -noxv
option, but then I can't save images.  If I don't specify -noxv I can
capture but either way it captures both fields (interplaced in one
frame).  Zapping will capture stills without being interlaced.  I have a
libmpeg.zapping.so in the plugin directory, but I can't seem to figure
out how to use it.  (any ideas?)

I've used mp1e with great success for capturing movies.  Even my k6-2
300MHz is fast enough to mpeg encode in realtime.

I'm running 2.4.16 with v4l that came with the kernel.
