it seems i have not made myself clear.

at program startup, i enumerate all components and save a list containing ONLY those that have the "canMovieExportFromProcedures" flag set.

I put this list into a menu.

the user chooses from this menu

then presses the "edit" button.

so I want the dialog to come up ONLY allowing audio settings on the component they have already selected, i want to turn off the ability to choose video, or make any video settings

if the user wants to select a different component, they cancel out of the dialog, and pick something else from the menu

Don't you want to display the dialog to allow the user to chose an audio codec and settings?

but that means the user hasn't selected which codec to use. the user has already selected the type and subType, i can't change it out from under them. In only want to limit the dialog to NOT allow video.

Try using the audio component "StandardCompressionSubTypeAudio" and call SCRequestImageSettings(audioComponentInstance) to open the audio only dialog.

How do I bring up the "ExportFromProcedures" dialog, but limit the choices to audio-only?

Here's what I've got so far:

1) make a list of components that have the "canMovieExportFromProcedures" flag set.

2) the user chooses one and hits the edit button

3) open that component, (set the "kQTMovieExporterPropertyID_EnableHighResolutionAudioFeatures" flag)

4) call "MovieExportDoUserDialog".

the only problem is, this dialog allows video. eg: under "3G" you can pick the "video" tab, or under QuickTime, you can check the "Video" checkox, enabling the group.

is there a flag I can set or test for to turn off the availability of video?
