1000 4/4 Intra frame period in
milliseconds.
s<0~(m-1)>_svc_svclayer 3 3 1/4 SVC temporal layer.

riction
average,
upperbound
average 4/4 “average” indicates the
average bit rate will be equal
to its target bit rate.
“upperbound” indicates the
bit rate will always not
exceed its target bit rate.
s<0~(m-1)>_svc_prioritypol

framerate,
imagequality
framerate 4/4 The policy to apply when the
target bit rate is not
sufficient to satisfy current
encoded conditions.
“framerate” indicates frame
rate first.
“imagequality” indicates
image quality first.
