How to Covert Dual audio AVC in MP4 and MKV to AVI.pls help

[dooms9day]

Please help me in these 2 subjects....
First..
I have a MKV with dual audio AC3 audio and I wanted to convert it into AVI without re-encoding...
Second...
I have a MP4 (AVC) with AC3 and I wanted to convert it into AVI.

I used ffmpeg.exe before and use that commands.....
ffmpeg -i input.mp4 -vcodec copy -an -vbsf h264_mp4toannexb output.h264
ffmpeg -i input.mp4 -vn -acodec copy output.aac

its create two files..one H264 file and one AC3 file(I used it in AVC MP4)
Now my problem is how I convert H264 file to AVI without re-encoding like ffmpeg.exe..
one of "ffmpeg.exe" Readme file guide this.....>
"Mux h264 to avi using avc2avi. You have to specify the correct frame-rate."
I use avctoavi but can't able to use it,,in the other way I can't type the correct commands or syntax.
please tell my easiest way if u can..(easy commands)

and want easiest way or syntax. in the above post,,,the commands is
Example:
convert avc in mkv to raw:
ffmpeg -i input.mkv -vcodec copy -an -vbsf h264_mp4toannexb=norepeatheader output.h264

convert avc in mp4 to avi, set container fps to 29.97:
ffmpeg -i input.mp4 -vcodec copy -acodec copy -vbsf h264_mp4toannexb=avihack -muxerfps 30000/1001 -vtag H264 output.avi

but it wont work.....

avc2avi -f 29.9700 -i input.h264 -o output.avi

Then, try adding the ac3 stream with AVI-Mux GUI

or

with VirtualDub.

HTH.

[dooms9day]

Ok,, thanx brother...its done by using this syntax "avc2avi -f 29.9700 -i input.h264 -o output.avi"
but the Format ID is still AVC....is there any way to convert mp4 avc to avi in DivX or XviD without re-encoding........?

[sneaker_ger]

No, that is impossible.

[dooms9day]

Why do you want to convert AVC/AC3/MKV into AVC/AC3/AVI? What is the poblem with MKV? Or MP4?

[sneaker_ger]

Dual audio mkv to avi:
1. convert the video to xvid/avi with one of the many GUIs like e.g. StaxRip, MeGUI etc.
2. extract the ac3 audio tracks using mkvtoolnix
3. mux everything together using AVI Mux GUI

Because my stand alone tv dvd player cant play MKV..

Using StaxRip and MeGUI is very difficult to me,,once I use it but I cant able to use them....StaxRip and MeGUI is the tools for advance multimedia users..

If you dont want to take the time to learn the tools, then buy a new standalone that plays mp4 and mkv. Also if your standalone wont do mp4 it likely will not do AVC in AVI.

[detmek]

In that case, you have to re-encode video stream, too. Standalone DVD players can not decode AVC video stream.
You could try XMedia Recode. Its free and I think it supports dual audio. Other options are Avidemux, Xvid4PSP, MediaCoder, Virtualdubmod + Avisynth, Dr. Divx 2.0 + Divx codec.
