p2p room means the all streams connections will be built between the participants, and usually called mesh network.
hybrid is both forward and mix modes, forward mean published streams will go through MCU and can be subscribed by others, mix mode means MCU will mix participants published streams, the new generated mixed stream can also be subscribed.
p2p room is now deprecated and no longer supported, so not suggest to use.
Thank you for patience back.
when i use MCU mix mode, sif resolution .i found on server side the bandwidth is about 330 Kbps for each user. is there another resolution (except sif,vga,hd720p... in userguide or roommanager ,like qsif ) or method to reduce the server side bandwidth.
The smallest mix stream resolution we provide is around sif or cif, otherwise we think there is no necessity to do mixing. For bandwidth saving, we will provide setting in coming 3.3 release, the smallest bitrate option for sif is around 200kbps. Is that OK to you?
@Bruces, v3.3 will be officially online around later January. For mix stream, the smallest video bit rate will be sif around 200kbps, otherwise we think that doesn't need mixing.
@Shiva, please see the description in white paper about p2p and MCU difference https://software.intel.com/en-us/articles/collaboration-suite-for-webrtc, RabbitMQ is used as event bus for MCU internal components communication.
