When running ffmpeg, it says: |
| 21 |
|
| 22 |
"This program is not developed anymore and is only provided for |
| 23 |
compatibility. Use avconv instead (see Changelog for the list of |
| 24 |
incompatible changes)." |
| 25 |
|
| 26 |
So try with avconv instead. But for MP3, you should probably be using |
| 27 |
LAME with a VBR quality setting instead. |
