avcodec/h264_slice: set the SEI parameters early on the AVCodecContext

Browse Source 
It's better to do it before the buffers are actually created. At least in VLC
we currently don't support changing some parameters dynamically easily so we
don't use the information if it comes after the buffer are created.
