In general, this is not considered a good idea (for the reason that you found out and that - imo obviously - cannot be solved: No matter how fast your hardware is there will always be a longer video or a video with higher resolution). If you absolutely have to build an index, do it for shown frames at playback time. You can of course only parse the video (instead of decoding it) but remember that for "real" video codecs, the information you get has limited relevance - just let FFmpeg do the seeking...
