Hi!
I'm new in Quicktime, and decided to use it because
i've a Mac/Windows Application to write.
I use Quicktime to load mp3/aac files and extract
audio in PCM format for using it in my application.
I tried to use different things in quicktime
(MovieAudioExtractionFillBuffer/SoundConverterFillBuffer/PutMovieIntoTypedHandle)
and find out that the most efficient is
SoundConverterFillBuffer. It needs 6s to 10s to decompress datas for a 8mn track
(depending on the hardware).
When i launch Quicktime Player and load the same
mp3, it is instantly available and playable wherever i play the track (beginning
or end).
Is there any explanation?
thanks in advance
emilie
