How Convert MP4 to AVI without re encoding.

[dooms9day]

I have a video of MP4 with the audio of AAC and I wanted to convert it into AVI without re encoding. is there any way to do that..
and another thing, can I get only AVI video from it and remove audio..?

[buzzqw]

ffmpeg all the way!

ffmpeg.exe -i myfile.mp4 -vcodec copy -acodec copy file(audio+video).avi

ffmpeg.exe -i myfile.mp4 -vcodec copy -an file(video_only).avi

What u say.? I can't understand...I m beginner tell me in easy way..I think u tell me avi synth scrypt............

since I'm a bit bored atm here's what buzzqw ment with it:
ffmpeg.exe -i myfile.mp4 -vcodec copy -an file(video_only).avi
1. download a static ffmpeg build (e.g. from http://ffmpeg.arrozcru.org/autobuilds/)
2. extract it
3. open a console
4. use cd "Path to where you extracted ffmpeg to" to get into the ffmpeg folder e.g. cd "d:\my encoding tools\ffmpeg"
5. write ffmpeg.exe -i "path to your mp4 file" -vcodec copy -an "Path to output avi file" (and hit enter ;))
e.g. : ffmpeg -i "e:\my mp4 files\remuxMe.mp4" -vcodec copy -an "q:\my avi files\output.avi"
-> ffmpeg will now copy the video stream from your input .mp4 file into the output .avi file.

BIG FAT WARNING: FFmpeg will not work!
Currently FFmpeg does not support frame copy of AVC video stream from any non-AVI format to AVI. And FFmpeg does not support frame copy of AAC audio stream from any format to AVI, even AVI->AVI is broken.

Currently I am working on fixing these bugs and this requires a lot of hacks on FFmpeg. When I finish this it is less likely to be submitted to official svn because ffmpeg-devels do not like hacks.

Here is how to do it. First grab the following tools:
mp4box or ffmpeg, avc2avi, dtsedit(optional), avitctools(optional), AVIMux_GUI(optional)

Steps:
1) MP4 -> raw: Use MP4Box or ffmpeg to extract AVC and AAC streams.
ffmpeg -i input.mp4 -vocdec copy -an -vbsf h264_mp4toannexb output.h264
ffmpeg -i input.mp4 -vn -acodec copy output.aac
or
mp4box input.mp4 -raw 0:output.h264 1:output.aac
2) Mux h264 to avi using avc2avi. You have to specify the correct frame-rate.
3) If your video is vfr, you need to extract timecodes using dtsedit and create vfr avi using avitctools.
If you need audio:
4) Mux video AVI and aac stream to AVC+AAC AVI with AVIMux_GUI.

Okay - time to drop back and punt.

1. open the mp4 with virtualdub.
2. Go to the video tab and select "direct stream copy".
3. go to the audio tab and select "direct stream copy". (probably already selected)
4. go to file tab and select "save as avi". no re-encoding will be done, and it'll take maybe 5 minutes.

Works for me every time.

1. open the mp4 with virtualdub.

Good idea, except VirtualDub does not natively support MP4/AVC nor AAC . Please tell the OP (and me ;)) where to download.

BTW, I tried AviDemux 2.5 with Video:Copy, Audio:Copy & Format:AVI, but both MPC-HC and WMP only display black screen with audio. Turning on indexing changes it to a green screen. ;) A later version might fare better, I don't know.

Cheers,

I am unable to find the tool. :confused:

Probably he meant the avi_tc_package written by tritical:
