[MPlayer-users] mencoder input from fifo with yuv4mpeg problems

[Mike Albon]

Hi,

I am having problems with reading data from a fifo into mencoder. My
output source is from Mplayer using the line:

mplayer -dvd 1 -dvd-device /dev/sr0 -chapter 1-7 -sub
~/Documents/Anime/Scrips/dump.mpsub -vo yuv4mpeg -ao null -osdlevel 0

Using the command:

mencoder stream.yuv -vc yuv4mpeg -ovc divx4 -divx4opts
min_quant=4:max_quant=6 -o blah.avi

I get the output:

MEncoder CVS-020413-12:04-2.95.4 (C) 2000-2002 Arpad Gereoffy (see
DOCS!)

However if I make a real file I can encode that with no problem. Is this
expected behavior, or have I done something completely wrong?

My system information:

Debian Sid running on a Pentium 3-m 1133Mhz. The CVS was updated
Saturday.
GCC 2.95.4, GlibC 2.2.5

Many thanks
