Hi ! ;-)
When mplexing with the profile #3, the size of the final mpeg
file is (four time) bigger than with the profile #8.
Example :
-rw-r--r--1 coco coco 44070912 Mar 6 21:08 f3.mpg
-rw-r--r--1 coco coco 11233280 Mar 6 21:08 f8.mpg

Hello,
Second test with y4mscaler and yuvscaler. Input is the same than in the
previous test (mjpeg avi 768x288 PAL). This time I'm scaling to VCD
and SVCD resolutions.

I've put up RPMs+tarball for mjpegtools-1.6.2 release candidate 1

Hello,
I'm trying to compare output of MJPEG avi converted to SVCD with 1.6.1
and 1.6.2. The strange thing is the final filesize.
With "mpeg2enc -q8 -f4 -a2 -I0 -42 -41 -S795 -B216", I'm getting that :
- video-svcd_q8-1.6.1.mv is 14M
- video-svcd_q8-1.6.2.mv is 17M
With "mpeg2enc -q8 -f

You can do 2-pass mpeg2 with ffmpeg CVS.

Hello,
I'm wondering what is the pixel aspect ratio value for 1/2 D1 (CVD)
resolution. This is for use with y4mscaler.
I've calculated myself and found 295/132 :
(59/54)*(720/576)*(576/352) = 295/132
(source is http://www.mir.com/DMG/aspect.html)
But, also found a pixel aspect ratio value o
