Panasonic MPEG4 Extra Fine Mode (D-SNAP/SV-AV)

[kwanbis]

My Panasonic's D-Snap SV-AV25 produces ASF files with MPEG4 Video (640x480) and (supposedly) G.726 for Voice. I was told to demux the stream to a raw .m4v stream with videolan with the following command:

vlc 09.asf :sout=file/raw://raw.m4v --noaudio vlc:quit

and then mux it to mp4:

MP4Box -add raw.m4v -fps 25 output.mp4

but then, i have no voices on the final mp4. So the question is, how do i also transfer the sounds? and last, besides keeping the mp4, how can i also convert to a more widelly used format? (i would keep the mp4 for quality)

PS: here is a clip i recorder:

For those having problems with the Panasonic MPEG4 Decoder:

MPEG4: http://panasonic.co.jp/pavc/global/cs/d_snap/download/mpeg4.html
G.726: http://www.sharp.co.jp/viewcam/download/g726_download.html

G.726 is the voice decoder, IN CASE YOU CAN'T HEAR VOICES.

I was able to take out the WAV file with ASF Tools. So the questions now are:

1) How do i now merge the WAV with the raw mp4 to mp4?
2) To what, and how do i convert from the mp4 (or wav+raw mp4), to have a more viewable (not codec need) file?

.mp4 supports mainly aac, mp3 and mp2 audio

2) To what, and how do i convert from the mp4 (or wav+raw mp4), to have a more viewable (not codec need) file? [/B] what do you mean with "more viewable"?
.mp4 is propably one of the most widely supported formats in the software playback sector

if you define it as "no codec needed" than you might want to learn that you need for every encoded stream a "codec" to decode it of course...
unless you decode the video too to raw, but than you need really a lot of space, so thats not an option

if you want a format that is really everywhere supported encode to .mpg (mpeg-1), but this will mean that you will loose quality

So, how do i mux a wav with the raw mp4 to create an audio/video mp4? I can convert to mp3 or aac.

Also, how do i combine multiple files into one movie, as the cmacorder creates a file each time i press stop. Do i combine the original ASF first? or all the raw mp4 and all the wav and then mux them together?

In any case, I would keep the audio/video mp4s for quality viewing. But i also want to be able to see the videos on DVD players, either as DVD, or VCD, or SVCD. That is what i mean by more viewable.

I never did this before, so the more help the better. Thanks.

Just in case what i need is not clear:

1) Extract the video and audio from the ASF file.
2) Merge all the raw videos and (wav?) audios into one big movie
(example, i have 01.ASF, 02.ASF, 03.ASF, that are all part of a recording, and i want 01.ASF + 02.ASF + 03.ASF -> movie.mp4)
3) convert movie.mp4 to something viewable on DVD players.

Thanks again.
