Hello,

I am having this problem since I own Lumia device. Earlier there was no problem on other phones (Samsung etc.) but the Lumia seems to have an issue with its video format. When trying to convert mp4 to mp3 via application on the PC (tried several apps) it always outputs the 0bytes file or its like 4 seconds long. Is there any special application for Lumia format to convert?

BR,

You may try using the AOA Audio Extractor software from your PC. Just copy your video from your Lumia phone to your PC and then use that software.

P.S.
Just in case you encounter this with an antivirus software in your PC, too: My Bitdefender flags this software as potentially malicious, but I suspect that's because it's trying to extract a portion of a file into another file which some viruses also do... plus I set my Bitdefender to "maximum" levels. As long as you download the software from the official website, you should have no problems.

Thanks a lot! It works ;)
