for frame : 274   timestamp is:  0.0
for frame : 275   timestamp is:  0.0

However this leads to more questions at the time the video ends the time is 11 seconds but in this case for frame 275 timestamp is 0 ,why is that.

Secondly I can round these timestamps to get the result I want,but I feel that rounding is not the solution to the problem

Also I was looking for an answer that will help me use the flags mentioned in the above post.
