* avcodec/cuviddec: improve progressive frame detectionSergey Svechnikov2019-04-23
| | | | | | | | | | | | | There are 2 types of problems when using adaptive deinterlace with cuvid: 1. Sometimes, in the middle of transcoding, cuvid outputs frames with visible horizontal lines (as though weave deinterlace method was chosen); 2. Occasionally, on scene changes, cuvid outputs a wrong frame, which should have been shown several seconds before (as if the frame was assigned some wrong PTS value). The reason is that sometimes CUVIDPARSERDISPINFO has property progressive_frame equal to 1 with interlaced videos. In order to fix the problem we should check if the video is interlaced or progressive in the beginning of a video sequence (cuvid_handle_video_sequence). And then we just use this information instead of the property progressive_frame in CUVIDPARSERDISPINFO (which is unreliable). Signed-off-by: Timo Rothenpieler <timo@rothenpieler.org>

* libavcodec/zmbv: change 24-bit decoder channel order, from RGB24 to BGR24Matthew Fearnley2019-04-02
| | | | | | | | | | | | This brings the channel order in line with that used in 32-bit mode (BGR0). 24-bit decoding is disabled by default (#ifdef ZMBV_ENABLE_24BPP), and no prior encoders or sample videos are known to exist for this bit depth, so I consider this change in implementation is unlikely to affect anyone. The decision has been made in agreement with the DOSBox Development Team (dosbox.crew@gmail.com), specifically with harekiet, who wrote the original codec.
