New subject: MyPhone 0.4 Released

12 Feb 2008


      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
Simon

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,

This is strange. The bitrate is sent to the
plugin
...

codec. What codec are you using? what version of
h323plus and how old is your video plugin? I updated
...
the
H.263 plugin about a month or so ago, prior to
...
...
that it just
ignored these settings so that might be
...
...
the problem.
...
From the tracefile make sure the video frames are
being grabbed at the right fps (for 10 fps every
...
100ms)

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
...
http://www.h323plus.org/source/download/MyPhoneSetup04.exe
(2.12Mb)
...
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
...
...
http://www.gnugk.org/nat-traversal.html. It is
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.
...
