* avcodec/nvenc: only unregister input resources when absolutely neededTimo Rothenpieler2019-04-27
| | | | | | | | | | | | This reverts nvenc to old behaviour, which in some super rare edge cases performs better. The implication of this is that any potential API user who relies on nvenc cleaning up every frames device resources after it's done using them will have to change their usage pattern. That should not be a problem, since pretty much every normal usage pattern automatically implies that surfaces are reused from a common pool, since constant re-allocation is also very expensive.

* 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>
