Is there a way to determine the intended frame rate of content playing in the html video element?
Does the video element even know the intended FPS or frame count, or does it simply guess (maybe 24fps) and play at the guessed speed?
Here are my unsuccessful attempts:
Look for a FPS or FrameCount property on the video element itself--Nope!
Look for cross-video-format header info about FPS or FrameCount--Nothing consistent!
Look for an event that is triggered upon frame changing--Nope!
My next attempt is more complicated: Sample the video by capturing frames to a canvas element and count frames by determining when the pixels change.
Does anyone have a simpler answer before I do the complicated attempt?
