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 have been reading the thread [h323plus] unavailable H.264 plugin and missing H.263 CIF4/16 capabilities at http://lists.packetizer.com/pipermail/h ... 02346.html, but I don't see the answer.
Please help.
missing H.263 4CIF and 16CIF
Re: missing H.263 4CIF and 16CIF
By default H263 is limited to CIF however with some small changes you should be able to enable 4CIF and 16CIF.
Look at h263CodecDefn in h263ffmpeg and look for the 4CIF H.239 encoder and decoder definition (4CIF is enabled for H.239) you can use this as a basis to define a 4CIF video capability by modifying the default 720p definition (currently limited only to CIF)

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.
