Comment (by James):

 >This is grid type of heic image and ffmpeg is taking 40-60 seconds

 >I tried setup debugging and found
 libavformat/demux.c:avformat_find_stream_info is consuming most of the
 time.

 This grid based image has 49 separate HEVC streams, 48 of them being the
 actual grid and one being a thumbnail, and each of which will fire their
 own decoder. The slowness may be hevc_cuvid being initialized that many
 times just for probing.
