In this Linux quick tip we will show you how to convert MKV to MP4 container.īefore you can convert (or remux) an MKV file to an MP4 file, you must first install ffmpeg. However, a lot of other tools (Adobe Premiere Pro) do not support MKV files. I just kept it simple.I have found that a lot of Linux utilities use the MKV (Matroska multimedia container) as a default container for video. 😉 you can customize any of the commands for ffmpeg for your liking of course. If not I just wanted to share what I found.

The only issue I've had which I'm sure is a code issue, but it takes Transformers.(2007).(720p).mp4 to Transformers.(2007).(720p).mp4.mkv. When it finds MP4's it coverts them from AAC to AC3 to a new location then it moves the original file to a folder named Originals so I can make sure the converted file plays fine. I'm sure I'll eventually make it a bit more elegant, but for now it works just fine. loop.sh directly from the FFMPEG folder with the to be processed files. This is the little script I created to do my bidding.įor file in *.mp4 do ffmpeg -i '$file' -vcodec copy -acodec ac3 /Location.to./'$'.mkv mv '$file' /Place.to./ doneīasically I run. So far I've converted at least 20 or so MP4's to MKV's converting the AAC to AC3. Updated this post with a more direct way of finding the FFMpeg Build Files. I didn't do any of the symlinking since I planned on calling FFMPEG directly. I ended up simply downloading the FFMPEG he had in his script via a browser and dropping it on to my cache drive and following his tar command into a ffmpeg folder. Great now the above gave me an idea on how to convert a bunch of files, but I still need FFMPEG to work and I never could find a build that didn't cause any issues. I couldn't really find a solution until I found this discussion yesterday. I just wanted to do some basic coding and have some magic work for me. I have/had a need to do some converting of Movies from AAC to AC3 because my Receiver doesn't support AAC and I didn't want to run any dockers or fancy apps.
