MP4 to MKV Script

[vinniel]

I think I'm slowly getting the hang of Avidemux scripts, but I need some help on the container part.  Has anyone written a script to convert all the files in a directory from MP4 to MKV?  Nothing fancy, here, just copy the video -- output as MKV. 

I can get it to work, manually, and Avidemux does some wonderful MKVs for the USB input on my DVD player, but I checked, and I have 147 mp4 files in one directory.  I'm not real anxious to do all those files manually.

Thanks!

Thanks!  I'll give it a whirl.

Keep in mind this is not re-encoding. The settings in GUI are for Video: Copy and Audio: Copy. If you need re-encoding need to work with run your specific job saved in avidemux (--run anyjob.py).
