Enables temporal layer identifiers in the encoded bitstream. Up to 3 layers are supported depending on GOP structure:
I- and P-frames form one layer, reference B-frames can form a second layer and non-reference b-frames can form a
third layer. Decoders can optionally decode only the lower temporal layers to generate a lower frame rate output. For
example, given a bitstream with temporal IDs and with b-frames = 1 (i.e. IbPbPb display order), a decoder could
decode all the frames for full frame rate output or only the I and P frames (lowest temporal layer) for a half frame
Returns the enum constant of this type with the specified name.
The string must match exactly an identifier used to declare an
enum constant in this type. (Extraneous whitespace characters are
name - the name of the enum constant to be returned.
