alacit's Issues

ffmpeg error on ubuntu server 12.04, solution included

Encountered the following error on Ubuntu Server 12.04.1 running in a Parallels VM:

Failed to set value 'alac' fo option 'c:a'

Traced it back to 'ffmpeg' (version 0.8.3-4:0.8.3-0ubuntu12.04.1).

Change line 57 of "alacit.rb" in the "lib" folder to:
command = 'ffmpeg -y -i "' + file + '" -acodec alac "' + m5a_file + '"'

and it works fine. Were you running a different version of ffmpeg?

Haven't been able to test on Mac (don't have a copy of Mountain Lion) if it breaks compatibility.

Missing ID3v2 tags

Audio encoded to ALAC format with alacit(1) is missing some metadata, notably gapless playback info. Apple uses the ID3v2 tag, iTunSMPB, for this purpose.

It appears that the ffmpeg(1) AAC encoder does not support gapless playback yet. Under OS X, one option is afconvert(1), described in Mastered for iTunes. Unfortunately, this involves several steps: FLAC => WAVE => CAFF => ALAC.

Different output directory

Hi there! This is awesome gem! Thanks for it!
It would be better and more comfortable if you add some parameter for change output directory.
