Selection of encoder and decoder for a video communications session
For a first device participating in a video communications session with a second device, some embodiments provide a method that receives sets of encoding features supported by each of one or more decoders of the second device. The method selects an encoder for the video communication session from several encoders available to the first device. The method selects a set of encoding features of the selected encoder based on the sets of encoding features received from the second device. The method transmits an encoded video bitstream to the second device along with information identifying the selected features in order for the second device to select a decoder to decode the bitstream.
