MKVExtract and MyMP4Box batch script

[mkr10001]

Can anyone do me a batch script that will take a folder of mkv files, demux them, then mux the h.264 and audio stream into an mp4 file with the same title?

[poisondeathray]

Is there only 1 video track and 1 audio track?

It's probably easier with ffmpeg

for %%a in ("*.mkv") do ffmpeg -i %%a -vcodec copy -acodec copy %%~na.mp4
pause

[mkr10001]

Yeah only one of each. I'll give that a go

[mkr10001]

Tried that, I get this

C:\Users\Michael\Downloads\ffmpeg-git-01fcbdf-win32-static\ffmpeg-git-01fcbdf-win32-stat
ic\bin>for %%a in ("C:\Users\Michael\Desktop\Season 2\*.mkv") do ffmpeg -i %%a -vcodec c
opy -acodec copy %%~na.mp4
%%a was unexpected at this time.

C:\Users\Michael\Downloads\ffmpeg-git-01fcbdf-win32-static\ffmpeg-git-01fcbdf-win32-stat
ic\bin>pause

sorry - misunderstanding

[mkr10001]

Thanks but now it doesn't like the spaces in the path. I have it in " " though

[poisondeathray]

It's a dos batch file - i.e. open notepad .txt file in same directory as video files, along with a copy of ffmpeg.exe , copy & paste code, rename .txt extension to .bat, double click the .bat to re-wrap

If you have spaces in filenames, put "" around it

for %%a in ("*.mkv") do ffmpeg -i "%%a" -vcodec copy -acodec copy "%%~na.mp4"
pause

Works like a charm, much better than the way I was doing it.

Is there a different method to doing it with avi's (to mp4's), I tried but by changing the mkv to avi and when I tried to add to zune (to sync with my phone) I get 'media type not valid'. Not sure if that's because it's not packaged correctly though

Same thing, just change "mkv" to "avi"

for %%a in ("*.avi") do ffmpeg -i "%%a" -vcodec copy -acodec copy "%%~na.mp4"
pause

The only things that you might need to change , are when there are multiple streams (e.g. 2 audio ), or if the stream number is different (e.g. video is track 1 instead of track 0) . Then you can use -map command

[mkr10001]

Hmmm not sure why it doesn't like these mp4's then :/

[poisondeathray]

the mkv to mp4's play on the zune? but the avi to mp4 doesn't ?


what kind of compression ? what specs ? use mediainfo view=>text , then copy & paste the report back here

some types of encoding settings (either audio or video) make the video unplayable on devices. The only way is to re-encode those; you cannot just copy the video or audio stream

[mkr10001]

Is this a standard thing to see during avi to mp4?

I was hoping I wouldn't have to reencode, but I might just need to give these ones a miss

Does the re-wrapped video play on a PC media player ?

Try ffmbc instead, and modify the batch script

You can find binaries here

[mkr10001]

Yeah it plays fine. I'll try that cheers

[mkr10001]

Nope. Not working either.

This zune software is awwwwwful.

[poisondeathray]

What about mp4box - mymp4box, yamb ? Do they play when remuxed with those

If not, it's probably an issue with zune then ? with xvid/divx

[mkr10001]

Yeah tried mymp4box. Didn't work with that. I think it must just be the codec.

ah well, thanks for your help. I can use that batch file for all my mkv's

[mkr10001]

Hi again,


Would it be possible for someone to edit that batch file to check for one of a list of audio codecs then if it matches, convert to mp3 or aac but keep the video stream the same?

Thanks
