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.

Regards, Bernhard

Hi Bernie,

I had to recompile (re-emerge in Gentoo) mjpegtools with quicktime and
dv included (with -f a the file size was over 2 Gig). Looks like I had
the right idea but not the precise way to get there. Followed your
instructions, but still not finshed. Note, I had to add -n n parameters
to the yuvscaler because it did not recognize the format. Here is the
problem:

The original video excap0001.avi is 753 MiB
The video_without_sound.avi is 5.7 GiB (same as with -a a)
The  sound.mp2 is 174 MiB

Why is the "Error in WAV header"?
My audio.wav file is 1.1 GiB

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_without_sound.avi &
mplayer -nosound -noframedrop -vo yuv4mpeg ezcap0001.avi

mplayer -vo null -ao pcm:file=audio.wav ezcap0001.avi
cat audio.wav │ mp2enc -v 2 -V -o sound.mp2

You need than to add the sound/audio to the video:
lavaddwav video_without_sound.avi sound.mp2 output.avi

If the avi file reaches the 2GB Filesizelimit you should change to
the Quicktime. You need to replace the yuv2lav option -f a with: -f q

output.avi contains video and sound, you can edit it with glav.
After editing you get the edilist file, you can process as you are
used. to.

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

Results:
(1) mplex in either forms complains about too many frames dropped
and then quits.
(2) mplayer plays the file, but it is a long video, so I stopped B4
completion.
(3) glav has the same error as in my initial post.

So I'm still asking for help. There is no video editor available for
Gentoo. I like glav and would like to use it for my video files
transferred from old video recorder tapes.

Thx - Janos
