VideoPlayer Error with 2017.3

I have two different projects that load local videos via URL into the VideoPlayer and they are now both broken. I am getting this error:
WindowsVideoMedia error 0x8007007b while reading file://F:/Unity-Source-Dev/MyUnityAppName/Assets/StreamingAssets/Flight.mp4

Context: MFCreateFile
Error details: The filename, directory name, or volume label syntax is incorrect.

The videos are H264 videos that have worked great until now. I tried taking them out of the StreamingMedia folder and re-importing them but no luck.

Here is my code that loads the video. Usually it works great and I love the new VideoPlayer.

public UnityEngine.Video.VideoPlayer videoPlayer;
public void loadVideo(){
GameObject camera = GameObject.Find("Main Camera");
currentVideo = "Flight.mp4";
videoPlayer.renderMode = UnityEngine.Video.VideoRenderMode.CameraFarPlane;
videoPlayer.url = "file://" + Application.streamingAssetsPath + "/" + currentVideo;
videoPlayer.loopPointReached += EndReached;
videoPlayer.targetCameraAlpha = 1F;
videoEnabled = 1;
videoPlayer.isLooping = true;
videoPlayer.Play();
}

This code was working last week in two different projects (before I updated unity) and suddenly nothing. Any ideas that don't involve the video codec would be much appreciated.

 

I'm experiencing the exact same issue

 

Same issue here. Looks like I have to downgrade to 2017.1

 

Same here. Has anyone reported a bug?

 

I'll second that!
Video playback is working for me when the file is located in a "regular" asset path but as soon as it is moved to StreamingAssets playback wont work anymore. As our project relies on videos which have to be located in StreamingAssets this is very annoying!

 

My solution: leave out the "file://" portion of the url.

I will test that on the device but for now it helps in the editor for testing.

 

Hello everyone,
I reported an issue to Unity for this error, here's the link to it!

 

This error is still active in 2017.4.1
