I have been tasked to create a Video player which will play a portion of YouKu video (the Chinese Alternative to YouTube)
To accomplish this, I am using the seekTo function of the YouKu API and stop the video using a looping timer that constantly checks where the playhead is using the currentTime API function.
I have created the identical code for the YouTube player, and am noticing a considerable difference in the precision of the stop times between the two video hosts.
YouTube seams to give me quite a good accuracy. When I tell it to stop at 7.45 seconds for instance, the player will stop very close to that number (usually within .5 seconds)
YouKu on the other hand is very inaccurate - stopping sometimes 3 seconds after I have told it to stop.
Can someone explain to me why this might be? I am guessing that it has something to do with the i-frame encoding of the videos after they have been uploaded.
Any insight would be greatly appreciated. If you have any extra details / knowledge about YouKu, that would also be helpful. Thanks!
