I'm trying to make use of the jit.qt.broadcast object's mode 2, which supports streaming directly from a vdig.

I'm getting an error when I try to use this -- here are the arguments to the object that I'm working with:

jit.qt.broadcast 320 240 @mode 2 @unicast 1 @vip 127.0.0.1 @vcodec h263 @aenable 1 @acodec mpeg4 @samplerate 44100 @bitrate 16 @channels 2 @preview 1

I have a tested DFG1394 device (works with jit.qt.grab) and I have DSP status set to Core Audio, with the built in mic as the input. The settings in the Sound control panel are the same.

• error: jit.qt.broadcast: error -213 converting audio

• error: jit.qt.broadcast: could not get sdp

"IMPORTANT NOTE: No, you cannot choose input devices for audio and video yet. We know about this, and are working to fix this up."

* Any ideas on the error message I'm seeing?

* If the user can't specify devices in mode 2, what audio/video device does the object default to?

* Any word on when this might be fixed to allow user choice of devices?

* Will audio support always be excluded in mode 0?

jit-qt-broadcast-mode-2

siVBRCompressionNotSupported = -213, /*vbr audio compression not 

So, it would appear that QuickTime doesn't like your choice of audio 

As you note, there is some unfinished business to attend to w/r/t 

jit.qt.broadcast. I can't say when this will happen, but it's on the 

list of stuff to take care of for the next major release of Jitter.

Error -213 is:
siVBRCompressionNotSupported  = -213, /*vbr audio compression not  
supported for this operation*/

So, it would appear that QuickTime doesn't like your choice of audio  
codec in this mode.

As you note, there is some unfinished business to attend to w/r/t  
jit.qt.broadcast. I can't say when this will happen, but it's on the  
list of stuff to take care of for the next major release of Jitter.
