Andreas Rheinhardt	a247ac640d	avcodec: Constify AVCodecs Given that the AVCodec.next pointer has now been removed, most of the AVCodecs are not modified at all any more and can therefore be made const (as this patch does); the only exceptions are the very few codecs for external libraries that have a init_static_data callback.

Andreas Rheinhardt	cbb6ba2e86	avcodec/cavsdec, h264*, hevc_parser: Use get_ue_golomb_31 where possible instead of get_ue_golomb(). The difference between the two is that the latter also has to take into account the case in which the read code is more than 9 bits (four preceding zeroes + at most five value bits) long, leading to more code.

Anton Khirnov	7ea1b3472a	lavc: deprecate the use of AVCodecContext.time_base for decoding When decoding, this field holds the inverse of the framerate that can be written in the headers for some codecs. Using a field called 'time_base' for this is very misleading, as there are no timestamps associated with it. Furthermore, this field is used for a very different purpose during encoding. Add a new field, called 'framerate', to replace the use of time_base for decoding.	10 years ago
