vobStrea</title></head><body>
<blockquote type="cite" cite><font face="Arial" size="-1">My
understanding is the DVD specification has provision to support LPCM
audio sampled at 48K through private extension. I would like to know
if the vobStreamer sample application will be able to process and send
such stream through RTSP/RTP</font></blockquote>

<div>No, but it could easily be modified to do so. Streaming PCM
audio is easy; just use a "SimpleRTPSink" (instead of a
"AC3AudioRTPSink"). See, for example our
"testWAVAudioStreamer" demo application.</div>

<div>One thing to watch out for: PCM data streamed within RTP packets
must be big-endian. If, instead, your source PCM data is in
little-endian order, then you will need to add a byte-swapping filter
before streaming it. (There is also an example of this in the
"testWAVAudioStreamer" code.)</div>
