Hi -
Oddity with y4mscaler that I'm puzzled about - seems it doesn't manage
to infer the 'norm' sometimes.
Using the 'pond.dv' clip from the libdv site:
smil2yuv -i 2 -a pond.wav ~/pond.dv | \
y4mscaler -S option=cubicB -O preset=svcd | ...
I get:

Yep -- off the camera in 16-235 range.

Thanks Selva, Good to hear...but...
I finished the encode with said parms and proceeded to mplex the streams
together. I let them go until they reached about 40 megs then stopped
them to see how the sync was. It sucked, but I used trial and error,
and finally -O 2700 seemed to line the audio up
Trying to compile mjpegtools-1.6.1
configure looks OK - it's at bottom hereto
make fails with a bunch of movtar errors - see below.
libmovtar is in /tmp/BUZ/libmovtar-0.1.3 I thought by doing
./configure --with-jpeg-mmx=/tmp/BUZ/jpeg-mmx
--with-movtar-prefix=/tmp/BUZ/libmovtar-0.1.3
I am pick
just dl'd the cvs driver per the recent instructions...
is the DC30 at all usable with this? I've got one lying about, and if
it'll work I'll use it (might even be convinced to be a test subject...)
input?

The "+16" is not NTSC setup. It is simply footroom in the Y'CbCr encoding
scheme for digital pixel data. NTSC setup is part of the spec for *analog*
transmission.
I understand that the lowest "legal" Y' value is 16. I assume it comes
right off my camera in the range 16

True. I don't think the unit of measure is 'v' though - isn't it a
percentage or dimensionless quanity (7.5 IRE in the US).

This time I actually tried unpacking it and compiling it.

Yah, I screwed up, and forgot to package
Hi -
I see that the y4m-config.h file and DBG macro/function problem is
known, if you stub out the DBG with something like this
"#define DBG if (0) printf" you'll run into the next problem:
g++ -DYS_VERSION_MAJOR=0 -DYS_VERSION_MINOR=4 -DYS_VERSION_PATCH=0 -O2 -march=i68
Could someone explain exactly when and where the NTSC setup (Y'+16)
should be added?
This much I think I know:
For NTSC DV, it is supposed to be added at the final analog output,
say at the camera when output to TV. To get the same effect when
playing on the computer, it needs to be added digit
The binary works fine, but when compiling I get:
g++ -DYS_VERSION_MAJOR=0 -DYS_VERSION_MINOR=4 -DYS_VERSION_PATCH=0 -O2 -march=i686
-mcpu=i686 -I/usr/local/include/mjpegtools -Wall -W -c -o graphics.o graphics.C

Hi, all,
Sorry for the extended delay. y4mscaler v0.4.0 source and x86 binaries
are now available, at the usual spot:
http://www.mir.com/DMG/Software/y4mscaler.html
The delay was because I was planning to put up a good clear demonstration of
the benefits of using smil2yuv and y4mscale
Hi Selva,
You've got me worried now! Just when I thought I had a handle on this
process...
No, my source material is not exactly 24, it's from an ntsc DVD and it's
23.9 something - i thought that the target rate to shoot for was 29.9
something as well! Aren't these fairly common values?

Hi,
I'm trying to get the Buz driver loaded on Red Hat 8.0.
I downloaded the source from the driver-zoran directory,
updated the tag to ZORAN_VIDEODEV_2, and compiled.
The compile worked fine, some warnings like:
#warning Using temporary hack for missing I2C adapter-ID for zr36067
make install
22 matches
