How to convert mpeg to mp4?

Question

I would like to convert an MPEG TS file to MP4. Is there software for Ubuntu that I can buy that just works?

In 13.10 I did the following with success: Edit the file with DVB-CUT and export to MPG. Then open the MPG in WinFF, select MP4 with High Quality preset and convert but in 14.04 this fails with the following error:

Solution 1

You could use VLC to convert mpeg files to mp4. To do this:

• Open VLC

• Click on Media in the menu bar and select "Convert / Save"

• In the "File" tab, click on "Add..." button and choose the file to convert from the file browser dialog box that opens up

• Click on "Convert / Save" and verify that the source file is exactly the one which you want to convert and give an appropriate file name for the destination file, appended with ".mp4" and choose the format for the destination file. In your case this would be "Video - H.264 + MP3 (MP4)" and then click on "Start"

This may take some time depending upon the length of the file and when it finishes, voila! You have your file ready.

Solution 2

Your copy of avconv is missing the encoder libvo_aacenc which you can restore by simply installing the extra libavcodec package:

sudo apt-get install libavcodec-extra-54

This should allow WinFF to convert to aac again!

Mind you the better aac codec is libfdk-aac but I believe this is not available in the 14.04 avconv / libav-tools...

Take a look at HandBrake.

Thanks, I was just about to try Handbrake which I have used before but find a bit complicated when I tried the VLC method described below.

Worked exactly as per your instructions. Thank you!

While this did work, the resulting mp4 file didn't play correctly on an iPad.

Doesn't this cause problems in removing libavcodec54?
