I'm trying to figure out how to get more accurate seek times (to milliseconds). I've been using the VideoDisplay and imported Flash's FLVPlayback component to Flex. For the reference video I'm using, I get about a 3-4 second accuracy, when the frame rate is at 30fps.
>From my understanding, all video files loaded into Flex/AIR are considered progressive downloads, and therefore can only seek to keyframes*. I've been messing around with a couple ideas: - skipping to the previous keyframe, play, and pause on exact time - extending videoplayback/video class to take a "screenshot" of the frames in between - dynamically creating cuepoints for the video at 100 ms intervals It would be great if you guys comment on other suggestions or the feasiblility of the above solutions. * Just for reference, this is the javadocs for FLVPlayback.seek(): "Seeks to a given time in the file, specified in seconds, with a precision of three decimal places (milliseconds). For several reasons, the playheadTime property might not have the expected value immediately after you call one of the seek methods or set playheadTime to cause seeking. First, for a progressive download, you can seek only to a keyframe, so a seek takes you to the time of the first keyframe after the specified time. (When streaming, a seek always goes to the precise specified time even if the source FLV file doesn't have a keyframe there.) Second, seeking is asynchronous, so if you call a seek method or set the playheadTime property, playheadTime does not update immediately. To obtain the time after the seek is complete, listen for the seek event, which does not start until the playheadTime property has updated."
