I'm closing this thread for now. Thank you, Bernie and Stephen, for your
ideas and guidance. In summary:
The OS on my Fitlet2 computer is Gentoo, Desktop stable. It has Alsa
for sound.
After trying to resolve the Alsa / OSS issue with help from Gentoo Forum
community I found a solution to the sim

Hi Bernie,
I did a little research and math.
(1) The original video was recorded with a "Canovision 8" camcorder
purchased in the mid-80s. The spec says the CCD is 1/3 inch with 320k pixels.
This particular camera was made for the US (American)
market, and it has a simple RCA one vido and one RC

Hallo,
the workaround I did use was playing back the file without sound. So a
command like that should work: glav -a 0 output.avi
If that works you can go.
If the /dev/dsp does not exist try loading the kernel module snd-pcm-oss
using a command like that: modprobe snd-pcm-oss
You should find
Update:
I've installed alsa-oss and now glav does not die. But it is still not
working properly. Here is the command and terminal output:

Yes, it did.
Although glav still died because of missing /dev/dsp.
I remember from a few years ago that glav uses OSS not Alsa. Can you
please help what to do next?

Hallo,
my fault. You have a .wav file an need to add that to the video file.
So you can skip this command: cat audio.wav | mp2enc -v 2 -V -o sound.mp2
And just use that command:
lavaddwav video_without_sound.avi audio.wav output.avi
I hope that works.

Hi Janos,
I know I'm coming into this discussion a bit late but what kind of
editing do you need to do on the files? If it's just "topping and
tailing" - extracting specific timed sections out of the capture files
and encoding them to another file - then the way I do it is with ffmpeg
using s
Hallo,
Sorry for the delay.
When you want to convert the file so you can edit it with glav, you need
to change the commands a little bit so glav understand the AVI. You need
to create a intermediate AVI file:
mkfifo stream.yuv
cat stream.yuv │ yuvscaler -O SVCD │ yuv2lav -q 90 -f a -o
video_
Progress report after reading the FM.
Executed the followig commands:
mplayer -ao pcm:fast:file=audio.wav -v null ezcap0001.avi
cat audio.wav | mp2enc -o audio.mp2
mplex audio.mp2 video_svcd.m2v -o test.mpg
mplex -V -r 1740 audio.mp2 video_svcd.m2v -o test.mpg
mplayer test.mpg
glav test.mpg
Re
Hi,
Thanks, Bernie. One step closer.
I recompiled mplayer, and now the command works. I now have a
"video_svcd.m2v" file. It plays with mplayer but there is no sound.
So the next step: how do I make a complete file, video and sound, that
glav will be able to process for editing?

Janos

Hallo,
mkfifo creates a file where one file/process reads it's content, and
another process puts data into. You need is when program data can't pipe
direct to each other. So you create the named pipe. You start afterwards
the process that reads the data and as last step you put the data into i
