This allows for specifing P frame references needed for temporal scalability. Encoding a single stream with a single layer allows for the layer to be dropped and the stream to be decoded without artifacts. ChromeOS is planning to use this feature for the L1T2 web standard[1]. This allows video conferencing apps to encode once for a clients with different performance/bandwidth capabilities. The ChromeOS test framework ("tast") was used to verify that no regressions are present. This was done on SC7180 ("trogdor"). Verification of the added controls was done with a bitstream analyser to make sure that reference frame management is correct.

Sorry for the missing subject, another email has been sent with the correct subject. I didn't realize that this had gone through.
