For awhile I've been using the myvcd script to make video cds of the avis I have on my computer. When I upgraded to the 2.6 kernel it stoppped working so I thought I would just repeat the step myvcd takes manually and construct my vcds without the help of the script. After some reverse engineering and adding in various echos to the myvcd script I came up with this command to start making my vcds.
| Code: |
mplayer -noframedrop -vo yuv4mpeg -ao pcm -waveheader -v -osdlevel 0 "/path/to/file.avi" & cat - < stream.yuv | yuvscaler -v 0 -O VCD | mpeg2enc -4 1 -2 1 -N 1 -M 1 -r 32 -v 2 -s -f 2 -b 1152 -B 260 -V 46 -g 6 -G 15 -F 1 -n n -4 1 -2 1 -o /path/to/file.mpv
|
Unfortunately rather than working I get this output.
| Code: |
bash-2.05b$ mplayer -frames 100 -noframedrop -vo yuv4mpeg -ao pcm -waveheader -v -osdlevel 0 "incoming/Boogiepop_Phantom_-_01_-_Portraits_From_Memory_-_[P-A](3E132A45)[AniDB].avi" & cat < stream.yuv | yuvscaler -v 0 -O VCD | mpeg2enc -4 1 -2 1 -N 1 -M 1 -r 32 -v 2 -s -f 2 -b 1152 -B 260 -V 46 -g 6 -G 15 -F 1 -n n -4 1 -2 1 -o /home/loop/vcd/boogie1.mpv

And thats it, it sits there doing nothing. A quick check in top reveals that it isn't eating my cpu cycles. It appears to be just sitting there. Anyone got any ideas?

It seems mplayer won't work correctly if you put the "&" symbol after it.
| Code: |
bash-2.05b$ mplayer incoming/Ghost_in_the_Shell_Stand_Alone_Complex_-_21_-_Left_ Behind_Trace_-_Eraser_-_\[LMF\]\(b1c1715d\)\[AniDB\].avi &

mplayer simply doesn't show any video. |

The two or three times I did this, I used this script as a base:
http://www.mail-archive.com/mjpeg-users@lists.sourceforge.net/msg00893.html
important parts:
| Code: | mkfifo stream.yuv
mplayer -nosound -vo yuv4mpeg recording.avi -vop lavcdeint </dev/null &
mpeg2enc -o video.m2v -B 122 -f 4 -q 10 -I 0 -V 230 -n n -F 4 -r 32 -4 1 -2 1 -b 2430 stream.yuv --correct-svcd-hds --aspect 2
## Convert video to svcd |
From the code you gave you didn't
- make a fifo
- specify any inputfiles for the programs after mplayer
