android sdk h264 mismatch profile leading to transcode

[nanguantong]

FYI. web endpoint published h264/B，then android endpoint subscribed h264（webrtc sdp default preferred h264/CB），this mismatched param leading to owt-server started transcode module from h264/B to h264/CB, so this is very wasted cpu/gpu operation, way to solve this？（beside setting codec to vp8）

In addition，android subscribe web published codec vp8 screen-cast stream，the played video picture is very poor blurred, why?
