2019-01-12avcodec/vc1: fix decoding of old WMV3 formatJerome Borsboom
The position of the second MV predicitor candidate is slightly different for the old WMV3 format indicated by RES_RTM_FLAG. This patch fixes decoding of niceday.wmv on the samples server. Fixes: #6641 Signed-off-by: Jerome Borsboom <jerome.borsboom@carpalis.nl>
2018-05-21avcodec/vc1: FIELDTX is only present in interlaced frame I/BI picturesJerome Borsboom
If v->fieldtx_is_raw is not reset to zero, it may spill over from a previous interlaced frame I/BI picture. Signed-off-by: Jerome Borsboom <jerome.borsboom@carpalis.nl> Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
2018-04-25avcodec/vc1: more corrections for AC inverse quantization scalingJerome Borsboom
HALFQP should only be added to the inverse quantizer when the block is coded with PQUANT. When PQUANT is equal to ALTPQUANT, the original test for the addition of HALFQP fails. A negative value for mquant indicates that the value was derived from VOPDQUANT. Fixes #4372 Signed-off-by: Jerome Borsboom <jerome.borsboom@carpalis.nl>
2018-04-25avcodec/vc1: correct mspel for field-interlace B framesJerome Borsboom
mspel indicates the use of bicubic interpolation. The check wrongly included MVMODE MV_PMODE_1MV_HPEL as using bilinear interpolation. Signed-off-by: Jerome Borsboom <jerome.borsboom@carpalis.nl>

We need to pass more bitstream elements to the VAAPI VC-1 decoder in order to start doing interlaced decoding in hardware. Signed-off-by: Jerome Borsboom <jerome.borsboom@carpalis.nl>

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.
