I didn't looked at appendix B. But given that at page 7 of the RFC it is
stated: "...Each table is an array of 64 values given in zig-zag order,
identical to the format used in a JFIF DQT marker segment..." then I agree
that it couldn't be possible to use all the code of the RFC specification.

to get the good quantization value.
However if you use a non-zigzag table then the encoding/decoding must find
and pick-up the good quantization inside the table. This is up to the
implementation of the code.

This is a guessing but by digging in the encoded parameters you'll probably
be able to confirm this hypothesis.
If the "display" picture is really 800x600 as provided by the attached png
file then the stream parameter might specify a 800x600 video display. Yet
the camera might encode only the 592
his. Do they change the
config.cygwin like I did? Do they use their own makefile?
I really don't know. Just hope that what I found could help
other if they want to "cross-compile" live555 on Cygwin for
VLC Media Player.

I think it should be:
For example, if the SDP description contains "a=range:npt=0-25", then "-d
10" means "play the stream(s) for 10 seconds, then exit",

and can replace the file sink with most testing application. Feel free to

have
been tempted to suggest adding some callback mecanism to the method
MultiFramedRTPSink ::sendPacketIfNecessary() after the
fRTPInterface.sendPacket(...).
But I was wondering. Is there a better way to do that without modifying
MultiFramedRTPSink? May be at a lower level?

Indeed !!!
Thanks for the clarification.
Its much appreciated.

getFreePacket won't be freed and will
cause memory leaks. If I am right then some mechanism should be provided to
walk the chained list and free all the allocated buffered packets.

this
is to support other networking like ATM that has maximum MTU size of 9192 ?
Can I assume if the network router I am using to send RTP packet has a
maximum MTU size of 1500 that it is safe to set MAX_PACKET_SIZE to 1500 for
a RTP receiver implementation using the live555 library?
Thanks

Ross,
I have seen a few request asking how to compile the LiveMedia library for
Microsoft Visual 2005. I know the FAQ provides a link for this purpose. But
you have to go through many steps. I have a Visual 2005 solution file (.sln)
as well as the associated project files (.vcproj) for visual 2005
O.K. I found the answer to my question in the documentation
Of the code.
Sorry

I believe a file might be missing in the lastest release of the liveMedia
library since I cannot compile the application testGSMStreamer. The file
missing must be implementing the class createNewGSMAudioSource.
Could please check

Ross,
Give me a few days. I have to double check a few things and I will getting

However, for it to work correctly, you must feed it correct presentation
times.
I might not know the library code enough but at first glance it seems I
cannot because the mechanism is internal to the
MPEG1or2VideoStreamFramer/MpegVideoStreamFramer. Unless I change the
the same
timestamp initialization methodology.

I've been looking into this in the last few days. And I believe it might be
possible but it's rather unusual like Ross said. The DVD specification has a
private stream definition in a Mpeg2 program stream that allow LPCM. I have
been successful to have standard player like VLC to play a Mpeg2 progr
It may take 1 or 2 weeks before I'm ready to test but I'll let you know!
Many thanks

You probably own the first revision. ACC was added later. I went to the ISO
