Queries regarding time to decode and switch videos

[spaul13]

First of all great project. It seems like it uses GPU to decode. But I want to know how to get the decoding time of a video file?

I am switching the video file after some time.
if (Input.GetMouseButtonDown(0))
{
fID++;
m_VideoPath = "file:///E:/" + fID.ToString() + ".mp4";
OpenVideoFromFile();
Play();
}

Can u please tell me how to check the time to display the first frame from a video from changing the m_VideoPath (switching time). I am using 360 videos.
FYI, My 360 videos consist only 1 I frame.

Does it decode and display frames asynchronously?

--> I observed the changing the video file to the First frame to ready for play takes almost 50 ms. Is there any way to reduce this playback time?

For me, it seems like there is flashing on the screen whenever I am changing the video. Any suggestion on how to check the timing and can I effectively switch the videos to achieve 60 FPS will be highly helpful.
