[Mjpeg-users] mp2enc/streamer - problems with audio

[Chris W. <blo...@tp...>]

Hi there,

I'm trying to record video clips, and then encode them as
mpeg but am having difficulty with sound...I use SuSE 9.2
Pro x86_64 and installed the mjpegtools pacakge from RPM
(not a SuSE rpm, from FC2, to match my glibc version)...

Firstly I record an AVI with streamer. That plays fine in
xine, so I assume it can be used...

I then try this, as suggested in 'streamer -h'...

lav2wav +p file.avi | mp2enc -o audtrack.mp2

This gives the following error...

chrisw@linux:~> lav2wav +p file.avi | mp2enc -o audtrack.mp2
    INFO: [lav2wav] Norm set to PAL
**ERROR: [lav2wav] Error opening file.avi
**ERROR: [mp2enc] EOF in WAV header
**ERROR: [mp2enc] failure reading WAV file

I have also tried using streamer to output the audio and video
to separate files but when I run mp2enc to try and encode the
WAV I get this...

chrisw@linux:~> mp2enc -o audtrack.mp2 < audtrack.wav
**ERROR: [mp2enc] Input not a WAV file - has no "WAVE" tag
**ERROR: [mp2enc] failure reading WAV file

So the WAV file created by streamer actually isn't. Loading
that file into Audacity shows digital noise on the R channel
and nothing on the L. Is there something I can specify on the
command line to get WAV files done correctly?

I have tested an existing WAV with mp2enc and it works fine.

Video encoding is working fine and quite fast (I'm using an
Athlon64 3000+, so it should!), but I need something other
than static or silence to mplex video with! :-)

Kind regards,
