hi,
I'm currently using SoundManager to decompress Movie Tracks on my
own. I read my self the samples from the QuickTime movie then I feed
them myself to the SoundManager SoundConverter routines. This
technique has worked perfect for me in the last years. But I'm
thinking of scheduling time in the near future to update my engine to
latest technology.
So I have to make a choice between QT AudioExtraction or CoreAudio
decompression.
Obviously QT AudioExtraction is the most easy to use solution, but
has one major drawback. I can't feed it my own samples, correct me if
I'm wrong... So if I want to use it with my own Reading routines I
need to write my own DataHandler....
CoreAudio decompression doesn't have that disadvantage but it seems
to suffer from the fact that It doesn't support all the Audio Codec's
(or not as well like .mp3 for example) or am I wrong? I probably
need to support only .mp3, AAC , DV Audio, etc...
Q1:
===
So which direction would you recommend: QTAudioExtraction or CoreAudio?
Q2:
===
Is my understanding correct that AudioExtraction Decompression
architecture is based on CoreAudio codec in case the exsist?
Or does it still use the QuickTime componenents for decompression?
regards,
mvo
