The libgstvaapi core encoders are meant to support raw bitstreams only. Henceforth, we are always producing a stream in "byte-stream" format. However, the "codec-data" buffer which holds SPS and PPS headers is always available. The "lengthSizeMinusOne" field is always set to 3 so that in-place "byte-stream" format to "avc" format conversion could be performed.
