I've been interested in creating computer-animated videos for quite some time
now, and with the info from a Linux Journal article on creating DVD content,
I thought I had the final pieces to the puzzle.
I started with a basic POV-Ray animation, that is part of their distrobution,
called bounce. This creates a 500 frame animation with a grey ball inside a
grey room bouncing around. I set POV-Ray to output 720X576 png files for DVD
formated video. I then used png2yuv to create a video sequence in raw yuv
format. This worked fine, and mplayer can play the sequence, although slowly.
However, when I try to use mpeg2enc to convert the raw yuv video into DVD
quality mpeg2 stream, it fails with a malloc failed error. Here is an example
of the output:
bash-2.05a$ mpeg2enc -v2 -f8 -o bounce.m2v bounce.yuv

bash-2.05a$
I get the same error if I try creating any format mpeg from this raw video
stream.
Originally, I thought the problem might be the lack of nasm on my system, but
I've installed it and re-compiled the mjpeg tools and I still get the same
error.
Details of my system:
Built from scratch.
kernel 2.4.19
gcc-3.2

If the server is older than 6-12 months, or if your card is
newer than the above date, look for a newer version before
reporting problems. (See http://www.XFree86.Org/)

Any tips, pointers etc would be greatly appreciated. I'm not subscribed, but
I'll check the archives for answers if you don't want to copy me directly.
