Question Video first frame not at zero, transcoded its fps to see if it would fix but the error persist.

I have this code below from a youtube tutorial and his end works perfectly fine, but on my pc it has errors

Code (CSharp):

1. public GameObject cinemaPlane;

140.         btnPlay.SetActive(false);

Im not sure whats the cause, but my clip is only 1:10 minutes long and when played it skips first 2 seconds of the frame rendering my clip a bit laggy when played. showing the error "Video first frame not at zero"
I installed handbrake and transcoded my fps if that would fix it but when i uploaded the transcoded video the error was still there.

 

I don't have any other video players, but I did try uploading different video clips but they all seem to have issues. And apologies I'm completely newb to c#. where can I insert the VideoPlayer.waitForFirstFrame in my codes??

 

I tried this but it didn't work, I checked the WaitForFirstFrame box it didn't fix it, but this shows up after updating the code though
"WindowsVideoMedia error unhandled Color Standard: 0 falling back to default this may result in rendering issues"
does this color issues affects the video clip when played?

 

thers also this code error:
Unexpected timestamp values detected. This can occur in H.264 videos not encoded with the baseline profile.

 

I have the same problem. First video frame not zero: 256 (8.533333s)

- In VLC I can play the video with no problems from the second 0, but unity player only play from 8.533 seconds wich is really a problem for me.
- I could not find an answer from Unity explainig what exactly means "First video frame not zero: 256", Is not having P-Frames at the beggining?
- I can not share the link of the video
- Transcoding is not an option for me because Im playing a external videoFile (not in the project when the build is done)

If it's and encoding issue... what can I do to on the encoding parameters to fix it?
