Oh, that's a good point - there is the AudioExtraction APIs in QT - you could
use that to pull out the audio samples from an AMR file
Thanks! Using MovieAudioExtraction and the other high-level QT APIs I'm
able to decode the packets, although with some small annoyances.
It seems to require at least 10 packets at a time (I'd like to decode the
packets as soon as they arrive, it's for a streaming application), and I
need to create all the movie objects for every 10 packets I want to
decode, which gives quite a lot overhead. There seems to be some small
audible pops between the decoded buffers, probaby due to not retaining the
codec state between decoding runs.
But I guess all those issues belong to the QT mailing list, and not here.
But at least it's quite a big step forward, thank you!
