I'm accessing frames in a .MOV file with over 25K frames, 3840 × 2160, H.264 (High Profile), 60fps. Here are the timings on a fairly fast PC, starting from file open:
frame #100: 2.97s frame #1000: 28.39s frame #10000: 280.19s
Is it normal? Is there anything I can do to improve random access?
How do video viewers allow a fast-forward at the speed of a mouse dragging a slider? Are there other libraries with faster seek time?
