Hello Guys,

I would like to have different frame sizes for two endpoints, first I tried
to play around with H323Endpoint::SetVideoFrameSize, but it seems that part
changes the maximum allowed size, which means that if I switch the
videoFrameSize to qCIF, I wouldn't be able to receive CIF from the other
endpoint. my test only received QCIF.

I tried also to modify the OpalMediaFormat by using a GetWritableMediaFormat
for a capability, that ended with unusual CIF format while having a QCIF
resolution.

On the other hand, I looked Opal examples where they use an OpalManager, but
unfortuntly that seems incompatible with h323plus, while old openh323
tutorials and exampls don't have any video plugins support.

How I can manage to receive and send different resolutions (frame sizes)
using H323plus?

I appreciate a lot your help
Carlos
