2014-10-15lavc: deprecate the use of AVCodecContext.time_base for decodingAnton Khirnov
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.

2014-04-09mpegvideo: operate with pointers to AVFrames instead of whole structswm4
The most interesting parts are initialization in ff_MPV_common_init() and uninitialization in ff_MPV_common_end(). ff_mpeg_unref_picture and ff_thread_release_buffer have additional NULL checks for Picture.f, because these functions can be called on uninitialized or partially initialized Pictures. NULL pointer checks are added to ff_thread_release_buffer() stub function. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>

2013-12-22VC1: Fix intensity compensation performance regressionMason Carter
Fix https://trac.ffmpeg.org/ticket/3204 The problem was that intensity compensation was always used once it was encountered. This is because v->next_use_ic was never set back to zero. To fix this, when resetting v->next_luty/uv, also reset v->next_use_ic.
