Hi, Is there a way to adjust the quality of H.264 video codec for use in H323plus's application? I tried to invoke H323VideoCodec::SetTxQualityLevel() when the video logical channel is opened.

Is it possible for H.323plus to be compiled in Windows 7 - 64 bits (using Visual Studio 2010)? Can someone guide me on this? Thank you.

Re: compile H.264 plugin

Hi Simon,

I have downloaded the plugin from the URL you gave and placed them under c:\ptlib_plugin directory. But when I don't see H.264 codec is loaded in the sample application simple.exe. Is there some configuration that I must do? Please help. Thank you.

Re: missing H.263 4CIF and 16CIF

Hi Simon, where can I find the "4CIF H.239 encoder and decoder definition" you mentioned? It will be great help if you can point out directly on the right file/class/method. Thanks.

missing H.263 4CIF and 16CIF

Any idea why I cannot see H.263-4CIF and -16CIF loaded from the sample application simple.exe? Initially only H.263(sw) is loaded and after I commented the code line SetVideoFrameSize(MaxVideoFrame), I able to see that H.263-CIF and H.26-QCIF are loaded, but still not for H.263-4CIF and -16CIF. I ha...

Re: compile H.264 plugin

Hi Simon,

Thank you for the dlls. That will be the life saver.
Can you post or send me the header files, such as libavcodec\avcodec.h, x264.h, etc? Thanks.

compile H.264 plugin

Hi, I have some questions about compiling H.264 plugin using Visual Studio 2010. Based on the instruction from the ReadMe file, I suppose to compile FFMPEG and X264 using MinGW, but I have been trying to avoid this step. Instead, I am trying to use the DLL I can find online at http://mediatools.cs.u...

Re: Problem in compiling the tutorial

Hi Shrone,

Thanks for pointing out the solution. In addition to oleaut32.lib, I have to refer to ole32.lib as well.
