Get the Data from a DataSource
Hi,
I start with JMF. I use a processor to get DataSource from an audio file. Until there, all runs very well.
But after that, I would like to get the raw data of my DataSource to aplly a filter on these data and after that, to create a new DataSource with filters data and play these data with my processor.
I searched in the API documentation of JMF but I did'nt find the solution to get the raw data of my DataSource !
Someone could help me ? and give me an idea of how to proceed ?
Thanks for yours answers.
Sylvain.

Hi,
It seems no one has replied to this post. I have a sample code that can help getting raw data from a DataSource. Here it is:
PushBufferDataSource source = null;
source = (PushBufferDataSource)processor.getDataOutput();
/* Now we can retrieve the PushBufferStreams that will enable us to
* access the data from the camera
*/
PushBufferStream[] streams = source.getStreams();
camStream = null;
for (int i = 0; i < streams.length; i++) {
/* Use the first Stream that is RGBFormat (there should be only one */
if (streams.getFormat() instanceof RGBFormat) {
camStream = streams;
RGBFormat rgbf = (RGBFormat)streams.getFormat();
converter = new BufferToImage(rgbf);
break;
}
}
Please let me know whether it helped solving your problem..
