Re: [h323plus] MyPhone 0.4 Released
Simon,
Maybe the problem is that the funtionality that was implemented in the old H323_H263Codec::Read() method has gone away, isn't it? It seems that in that code was implemented the adaptivepacketdelay feature. Is right?

If memory serves me right the openH323 version never handled I-Frames. I will relook at the plugin codec to see what we could of missed.

Simon,
Unfortunately, even when the plugin codec code is called, MyPhone2 stills sending more video bandwidth than established. If I don´t move the camera, it sends about 50 kbps (the configured video bandwidth), but if I move the camera, to force sending I-Frames, the bandwidth increases until reaches more than twice the configured bandwidth. The same test works fine with the previous version of openh323 and MyPhone. What's happening? If you need them, I can send you Ethereal traces.
Best regards,

Ya'oops when a decendent is not a descendent. :( I have checked in a fix to h323plus CVS so the correct H323PluginVideoCodec::SetMaxBitRate() is called.
Thanks again

Hi,
Simon, I've traced down using the VS 2003 debugger, and the function which is being called is H323VideoCodec::SetmaxBitRate(), because the function OpenVideoChannel() receives a reference to H323VideoCodec, not to H323PluginVideoCodec. You can see this easily setting a breakpoint in this line codec.SetMaxBitRate(videoBitRate * 1024);, stepping into it and seeing the call stack. Here it is:

H323PluginVideoCodec::SetMaxBitRate() sends a messages "Max Bit Rate" to the plugin codec to set the maximum bitrate. This function also overrides H323VideoCodec::SetMaxBitRate() since H323PluginVideoCodec is a descendent of H323VideoCodec so the problem most likely is in the plugin codec not setting the max bit rate. I suggest you look at the H.263 plugin codec perhaps there is something missing.

Hi,
I've downloaded the
latest version of the plugin
codecs from the CVS, and I've seen that
the frames are
being grabbed at 10 fps. Additional testing
has showed me that the problem
seems to be with the following line
of code, in
CMyPhoneEndPoint::OpenVideoChannel:
codec.SetMaxBitRate(videoBitRate * 1024);
I think that the
problem is that codec is an instance
of H323VideoCodec, and the
implementation of
H323VideoCodec::SetMaxBitRate does nothing but
an
assignment. I think that what it should be called is
H323PluginVideoCodec::SetMaxBitRate, which is in fact
a descendant
of H323VideoCodec. I've tried to do a
cast from H323VideoCodec to
H323PluginVideoCodec, but
I get compilation erros due to the
undefined class
H323PluginVideoCodec, because in fact it is defined
in
a *.cxx file, not a *.h.
Am I correct? Or am I
missing something?
Best regards,
--- Simon

Hi, Simon:
I've downloaded the latest CVS
code with the
support for bitrate, fps and Adaptive packet
delay.
But it seems that MyPhone2 is not using the
settings. Let me explain this:
- I've configured the
following vlues for video:
fps = 10, Maxbitrate =50 kbit/s. and
quality = 15.
Size = QCIF. 2. If I capture
the video packets with Wireskark,
I can see that the bitrate is
about 300kbit/s.
Where is the problem? Am I
missing any additional
setup?
Best regards,

looks like you are right. I have
added support for bitrate, fps and also
adaptive packet delay
to the CVS.

Hi,
I'v been looking at MyPhone2 0.4 source code,
and I was
wondering how is the videobitrate, fps,
etc... managed, because
I've seen that all of this
parameters are read from the
configuration, but they
are never used.

Guys
> I have uploaded MyPhone 0.4 installer to the
h323plus website to garnish
some feedback on the
upcoming 1.20 release on
h323plus.
Download here

Important
Features
Native NAT traversal with GnuGk : This
uses the
new GnuGk NAT module now in
H323plus. You can send and receive calls behind
a NAT when
registered to
GnuGk on the public internet. The
only
requirement is that you enable
SupportNatedEndpoints in GnuGk. Note this is the
GnuGk NAT
Method
not the standard H.460.18/19.
Built
off the latest h323plus CVS. (hopefully
the baseline for
v1.20)
Notes:
To run in debug mode start myphone with
commandline
switches -ttttt (number
of t indicate
tracelevel)
After Install adjust the audio and
video codecs
to your preferred order.
G.711 & H.261 are the default.
The installer contains the full myphone2 source
code. The exe
was built with
vs2003. If you wish to build it
with a later
version of visual studio,
although not tested, you will need the $ version
as the
express version does
not seem to support
MFC.
Hopefully next week if there are
not too many
problems we will do the
snapshot and release v1.20.
