This is my first
post, however I've been searching and reading the list for the past two
weeks.
We have a windows
app where users create and output videos. I am responsible for and have
written the publisher (output module), which currently output AVI, WMV, RM,
and Flash. I am now in the process of adding QT movie output. We
need to output for the web and uncompressed which will have UI presets, and in
an advanced tab allows the user to choose form any of the components installed
(I may use the Standard Dialogs for this) I'm using QT 7 for windows
and have the latest QuickTime installed.
As our app renders a
show, my publisher is given raw audio and video one frame and sample at a
time. I am successfully creating a .mov using CreateMovieStorage, and
using the ICM to create a compression session and encode the video frames
using a CVPixelBuffer. Then I'm passing each encoded video frame and
raw audio sample into AddMediaSample2.
My question
is, which method and set of API's should I use to compress the Audio so I can pass the encoded samples into
AddMediaSample2 Originally I thought I should use the
SoundMgr's ConvertSound, but then windows update guide say to use
CoreAudio's ConvertAudio, but that's not fully supported and finally I read that
the SoundMgr is outdated and that I should use an Audio
Exporter.
Can
someone please help me get in the right
direction?
Thank
You
Joe
