hi all

I want to output a movie to a monitor using VOut component. I refer to the sample code that is samplevideooutput.

I do the thing following these steps:

1. select a component

2. openAComponent()

3.QTVideoOutputSetClientName()

4.QTVideoOutputSetDisplayMode()

until here, the code works fine.

5.QTVideoOutputBegin() // err! return -50.

6.SetMovieVideoOutput()

7.QTVideoOutputGetGWorld()

8.SetMovieMasterClock()

9. SetMovieGWorld()

10. StartMovie()

I print the infomation about the component and component instance, these are correct.

BTW: simpleVideoOutput can work fine using the same configuration.

any help or advice would be APPRECIATED!
