video Seek time not working

Archived

I am playing pre and mid roll ads in my video. i set mid roll ad interval of 5 min (300 seconds)
after playing the mid-roll ads, instead of showing video from 301 seconds onward, it shows from 0 seconds, i providing the time correctly, but do not know what going one

Explanation
i increment the variable “video_playback_time” and “ad_frequency_count” by each second. when “ad_frequency_count” i is greaten than equal to ad interval,
i play the mid-roll ads, then reset the “ad_frequency_count” to zero, once ads is complete, i am showing same video by providing “video_playback_time” in seconds.
In “get_video_object” function i am converting seek time into milliseconds.
video.Seek (seek_time * 1000) 'providing time in milliseconds

I don’t remember for sure, but you may have to call Seek() after Show() or even after playback starts.

For mid-rolls, a better approach might be to use the playStart attribute of your content-meta-data instead of Seek().

Solved this seek time issue for providing time in

videoclip.PlayStart = seekTime

where seekTime in seconds rather than in mili-seconds
