- introduce two new properties: * temporal-scalability-layer-flags: Provide fine-grained control of layer encoding to the outside world. The flags sequence should be a multiple of the periodicity and is indexed by a running count of encoded frames modulo the sequence length. * temporal-scalability-layer-sync-flags: Specify the pattern of inter-layer synchronisation (i.e. which of the frames generated by the layer encoding specification represent an inter-layer synchronisation). There must be one entry per entry in temporal-scalability-layer-flags. - apply temporal scalability settings and expose as buffer metadata. This allows the codec to allocate a given frame to the correct internal bitrate allocator. Additionally, all the non-bitstream metadata needed to payload a temporally scaled stream is now attached to each output buffer as a GstVideoVP8Meta. - add unit test for temporally scaled encoding.
