* lavc: deprecate the use of AVCodecContext.time_base for decodingAnton Khirnov2014-10-15
| | | | | | | | | | | 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.

* hevc: deobfuscate slice/tile boundary handling for DBFAnton Khirnov2014-08-09
| | | | | Use named constants instead of magic numbers, avoid using variables with inverse meaning from what their name implies.
