Panasonic MPEG4 Extra Fine Mode (D-SNAP/SV-AV)
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:
09.ASF
For those having problems with the Panasonic MPEG4 Decoder:
MPEG4: pavc/global/c...oad/mpeg4.html
G.726: viewcam/downl..._download.html
G.726 is the voice decoder, IN CASE YOU CAN'T HEAR VOICES.
MP4box at cd.asp?dir=/gpac/dev
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?

you cant mux .wav in .mp4
.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 quot;more viewablequot;?
.mp4 is propably one of the most widely supported formats in the software playback sector
if you define it as quot;no codec neededquot; than you might want to learn that you need for every encoded stream a quot;codecquot; 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 -gt; movie.mp4)
3) convert movie.mp4 to something viewable on DVD players.
Thanks again.
no one? any clue on what to look for on google? |
