* 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>
