[MEncoder-users] No idea what I am doing...

[Greg Heywood]

Thanks for all the help so far. Getting somewhere, but still a few issues.

I have tried two different methods with varying methods of success.

METHOD 1

1) Create a mencoder.conf file and populate it (with data largely taken from
the web). The file contains:

[ivtv]
tv=normid=10:norm=pal:device=/dev/video0:width=720:height=480
pvr=abitrate=192:vbitrate=2200000:vpeak=2600000:fmt=dvd:aspect=2:arate=32000
of=mpeg=1
mpegopts=format=dvd
ofps=30000/1001
ovc=copy=1
oac=copy=1
vf=harddup=1


The command line I used was:
mencoder pvr:// -profile ivtv -o encode.mpg -endpos 20

This seems to work OK, although the video that is captured is very grainy,
and mostly black and white static.


METHOD 2

Since there are default values for most of the options, I tried a basic
command line:
mencoder pvr:// -pvr aspect=2 -o encoded.mpg -endpos 20

Exiting...


There are more of the errno 22 lines, but I took them out to save space...

I guess the first method is closest to working, but it seems to be using
NTSC still, not PAL. I also used "v4l2-ctl -s pal" to set it to PAL (I
think), but mencoder still reports NTSC-M.

Any more tips on how to ensure that it records in PAL (if indeed that is the
problem)?

Thanks
