Good question. Should seeks go to the previous keyframe to the
requested time,  the next keyframe after the time, the closest
keyframe, or the exact frame requested?

Regarding that bug, I think it should be going to the last keyframe
then decoding up to the point of the requested frame so it can display
non-garbage data. But is there a requirement to be able to identify
keyframes from JavaScript? I suspect not but don't know.

What time is that exactly? Is that the time of  the actual frame the
seek ended on? Seek can take some time if it requires multiple http
byte range requests to find the right location, and to search for the
keyframe. You wouldn't want this to be a blocking call but it would
need to be if you want to return the time.
