RTP Processor Problems

[pyros77]

Hello,

i try to realize a streaming application with the jmf. If i want to deliver
a (JMF supported) file via rtp, i get the following message:

Format 0: H263, 352x234, FrameRate=29.9, Length=11684
Format 1: LINEAR, 32000.0 Hz, 16-bit, Stereo, BigEndian, Signed,
FrameSize=32 bits
dvi/rtp, 32000.0 Hz, 16-bit, Stereo, BigEndian, Signed, FrameSize=32 bits
Failed to build a graph for the given custom options.
Failed to realize: com.sun.media.ProcessEngine@1b963c4
Cannot build a flow graph with the customized options:
Unable to transcode format: LINEAR, 32000.0 Hz, 16-bit, Stereo,
BigEndian, Signed, FrameSize=32 bits
to: dvi/rtp, 32000.0 Hz, 16-bit, Stereo, BigEndian, Signed,
FrameSize=32 bits
outputting to: RAW
Error: Unable to realize com.sun.media.ProcessEngine@1b963c4


Why is the JMF trying to transcode the format?
I have re-installed the JMF, and use java 1.4.2

The strange thing is, it did work, the error occured without any changes. t
my desktop computer the application works fine with the
same configuration, same JVM, same classpath, same IDE.

Any ideas or similar problems?

Format 0 is the video stream.
Format 1 is the audio stream.
JMF doesn't support sending audio using LINEAR so it is trying to transcode it to a format it does support (DVI/RTP). You can see all of the different audio and video encoding formats supported using the JMStudio application.

You may be able to use Java Sound to transcode the audio.
