mp4 to mp3 convert

Garrett85 · 06-09-2015, 02:08 PM

Does anyone know a good program for converting mp4 files to mp3,s?

TobiSGD · 06-09-2015, 02:14 PM

I use ffmpeg for all kinds of conversions between multimedia formats.

ffmpeg or avconv (essentially ffmpeg) is good.
For a very simple conversion, it would go something like this:

Code:

ffmpeg -i file.mp4 file.mp3

To do a bunch, loop the file names with a for loop.

Did you run avconv?

$ avconv -i file.mp4 file.mp3

I'm not sure why the ubuntu repository is not providing avconv, especially since it's (apparently) preinstalled and have dropped their support of ffmpeg which..

you are aware that a mp4 is a MORE compressed file than a mp3
and BOTH are whats called " lousy" in that they toss DATA( information) into the trash can to compress the files

and mp4 tosses out even MORE information

do not expect the files to sound good or if video look good

expect a bit of a "bad" image quality

Garrett85 · 06-09-2015, 07:33 PM

I have made a mistake. I need to files to go from m4b to mp3. Any ideas?

John VV · 06-09-2015, 07:46 PM

being a audio book format

is it DRM'ed

if so .......

Garrett85 · 06-09-2015, 11:23 PM

No there's no DRM on the file. I try not to give any of my money to companies that DRM encumber their files. One reason I never buy from audible.com

Sefyir · 06-10-2015, 12:02 AM

It's probably the exact same syntax. Since you probably have avconv

Code:

avconv -i file.m4b file.mp3

TobiSGD · 06-10-2015, 03:31 AM

If I am not mistaken, avconv is provided by the libav package, try to install that.
