javascript - When changing video currentTime too much, video fails? -


i'm using user drag event keypresses change position in html5 video element , updating video time accordingly using:

video.currenttime = totime;

and updating canvas based on video position grabbing video , putting canvas.

another element video time frame number, i.e:

framenumber = 123; fps = 25; totime = 123/25;

problem is, every fails. fails mean lose video; stops working altogether.

most of time works great fails, , not @ same point either...

any ideas appreciated!

there 2 answers question:

  1. encoding of video files - controlling keyframes , sending right video right browser able solve lot of problems. using ffmpeg changed gop length.

    ffmpeg -g <frames> in case, <frames> amount of frames between gop points desired.

  2. using videojs serve video seemed solve lot of problems , made smoother experience.
