6f0e9a8634 avutil/avstring: Fix bug and undefined behavior in av_strncasecmp() 
The function in case of n=0 would read more bytes than 0.
The end pointer could be beyond the allocated space, which
is undefined.

703583dbb1 avcodec/cuviddec: improve progressive frame detection 
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).
