Firstly, my application is headless so there is no way to call
SGVideoChannel#settingsDialog() to set the codec, compression, etc.
I'm trying to figure out how to do this programmatically but I'm not
sure how what I see on the dialog maps to the API, if at all. On this
topic, I see some code related to MovieExporter that uses
AtomContainer (and shows how to save an AtomContainer for later use)
but SGVideoChannel doesn't appear to use AtomContainer.
It isn't readily apparent to me how I tell the SGVideoChannel
programmatically to use H.264 (for example).
Secondly, in SGDataProc#execute() I'm trying to use DSequence and
CSequence to first decode, then manipulate then encode the frame. I'm
having trouble getting everything to match up just right and I was
wondering how the various settings for SGVideoChannel map to the
constructors for DSequence and CSequence:
DSequence( ImageDescription desc, EncodedImage data, QDGraphics port,
QDRect srcRect, Matrix matrix, Region mask, int flags, int accuracy,
CodecComponent codec)
CSequence( QDGraphics src, QDRect srcRect, int cType, CodecComponent
codec, int spatialQuality, int temporalQuality, int keyFrameRate, int
flags)
Again, it isn't readily apparent to me how I get the CodecComponent
that would correspond to the H.264 I chose in the previous step
described.
Thanks for whatever help you can give.
Cheers,
Steve
