Hi Pieter3d, Can you help to answers the following questions about the VP8 and VP9:

1. For both VP9 and VP8, the alt ref frame and the golden frame are not for display?
2. For VP9, the encoded data are not packed into partitions as the way the VP8 does, i.e. there are only one partition, right ?
3. For SVC mode for VP9, is it correct that the application for encoder ( the sender in the case of video communication ) decide whether to send all the layers or just the base layer to the decoder( the receiver in the case of video communication ) ?
4. How the encoder get the infomation about the networking situation? by the RTCP feed back message ?

Thanks!
