Hi SuperMike,
Well, a problem might be the different syntax found with all the different versions of ffmpeg found with Ubuntu. The file I have on my Desktop from youtube is the following:
Code:
Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'Rammstein_Mutter.mp4':
Duration: 00:03:45.90, start: 0.000000, bitrate: 338 kb/s
Stream #0.0(und): Audio: aac, 44100 Hz, stereo, s16
Stream #0.1(und): Video: h264, yuv420p, 352x264, 24.99 tb(r)
And conversion of audio only with the svn ffmpeg, decreasing the bitrate a little is as follows:
Code:
andrew@skamandros:~/Desktop$ ffmpeg -i Rammstein_Mutter.mp4 \
-acodec libmp3lame -ab 192k Rammstein_Mutter.mp3

Output #0, mp3, to 'Rammstein_Mutter.mp3':
Stream #0.0(und): Audio: libmp3lame, 44100 Hz, stereo, s16, 192 kb/s
and this produces a stereo 192 kbs mp3. I am not sure how the stock Ubuntu ffmpeg handles aac audio though. But the sound and picture quality of the unaltered, downloaded mp4 file is pretty impressive anyway do you think?
