function cohPrebufferKeyframe

int cohPrebufferKeyframe(
    double timestamp
)

Prebuffers a keyframe for faster seek. Requires exact timestamp of the keyframe. Throws an error on failure.

Parameters:

timestamp timestamp of the keyframe in seconds

Return: a positive id if successful or negative value on failure

Note: Can only be used for videos containing metadata with keyframe information, support for partial requests and after readystate is greater than 1 (HAVE_METADATA)

function cohGetKeyframeTimestamps

sequence< double > cohGetKeyframeTimestamps()

Obtains the information for keyframe timestamps from video metadata.

Return: an array with keyframe timestamps in seconds

Note: Can only be used after readystate is greater than 1 (HAVE_METADATA)
