FFMPEG: AC3 to AAC conversion issues
try this: go to system/Administration/synaptic
and type libfaac
and install it.
if did not work try to install the FULL-FFMPEG from here. The ffmpeg package which comes with Ubuntu is incomplete.

Ok, this one has me scratching my head - and being a n00b isn't helping.
In short, I had a script which I had perfected to covert MKV video to MP4.
However, my Ubuntu 10.10 box bit the dust and installed 11.04.
However, my script is now having problems with the following line:
ffmpeg -i "${title}".ac3 -acodec libfaac -ab 576k "${title}".aac
When it reaches the relevant stage in the script, it returns the error:
Unknown encoder 'libfaac'
I have tried swapping libfaac for aac, which seems to be installed/recognised by ffmpeg - however that codec is just way too slow.
I have no idea how to either;
- get libfaac back on my Ubuntu 11.04 install, or
- find a better codec than AAC to convert the audio.
Any help to point me in the right direction is greatly appreciated.
