With Steven posting these killer matricies, maybe he should change his name

Hello.
Up to now I have been converting my avi movies to
SVCD using transcode or mplayer to decode the input
stream into a yuv4mpeg which is fed to mpeg2enc.
I want to experiment lav2yuv for that purpose, but
I am having problems with it. Maybe I am doing the
wrong thing.
I have a test.avi file,

An important thing to bear in mind is that VBV buffer *not* the same
thing as the decoder video buffer (STD_buffer)!! The VBV is, basically,
an irrelevant 'appendix' th

Again: there are *two* video buffer size parameters.
1. vbv_buffer_size. A 'left over' in the sequence headers from MPEG-1 that
just has to be filled in more or less any
Hi
Just made the move to the .92 stable version (from sourceforge tar.gz).
gcc is 3.0, MDK 8.2
I have an error running mpeg2enc via Kino : malloc failed.
Got rid of all the possible options (-4 2 -2 1 etc...). No way.
Has it been reported somewhere already ?
Thanks
Edouard

but what version of glibc? 2.2.5 or earlier have known issues
that are being worked on.

OK, riddle me this.
I have a script that I use for converting a smil file (of edited DV) to
DVD-compatible mpeg. The script looks like this:
start script
#! /bin/sh
mkfifo stream.yuv
mkfifo video.yuv
smil2yuv -a "${1%.smil}.mp2" "$1" >stream.yuv &
cat stream.yuv
Given some of the problems I've been having with yuvkineco I thought I'd try using
mpeg2enc with -I 1 and pass it interlaced material.
So I ran the following sequence:
exportvideo -D 0 -Y 2 {filename} | mpeg2enc -f 8 -i 1 -q 4 -g 6 -G 18 -n n -F 4 -a 2
-s

This is a typical symptom of the field order getting reversed. Fix that,
and you'll never forget the difference. :)

I changed it to:
exportvideo -D 0 -Y 2 {filename} |
yuvcorrect -T INTERLACED_BOTTOM_FIRST |
mpeg2enc -f 8 -F 4 -a 2 -s -q 4 -i 1 -g 6 -G 18 -n n
Burned it, and it now looks even worse than before :-( Am trying INTERLACED_TOP_FIRST
next, but believe I'd already given that a try. Will see.
Got it. Passed it -z t and it looks GREAT!
Thanks to those that replied. I think this is going to work out great!
