Unity WebGL VideoPlayer not working - No decoders for requested formats: video/x-ms-wmv

Hi,

I am having a problem with playing Video on WebGL on Firefox. My Unity version is 5.6.0f3. I am playing the video from URL, but when it doesn't work, and the warning I am getting is

Cannot play media. No decoders for requested formats: video/x-ms-wmv

Any help would be appreciated, thanks.

 

Can confirm this is still an issue with 2017.2.

File is mp4 wrapped, imported with basically default settings.

 

Update: changing transcoding from h264 to vp8 removes the error message, but the video still doesn't play. Tried various transcoding settings in Unity, no change. Tried uGUI (via RawImage) using a render texture, and quad in scene using material override.

Tried encoding video file using h264 with premiere (had previously tried w/ VLC).

Screenshot of tests included. Right side is UI element, left is quad, both trying and failing to play video.


Console output is below - this test was in Firefox. Seeing same thing in Edge.

I have the exact same problem. h.264 encoded video plays during editor, but not build.

Both URL and in-game video does this. Using 2017.1.1f1, tested on firefox and chrome

 

Hi Julien! It's Ricky. I'm having the same issue ;(
When I open the game as an app from my desktop it works great. But when running my game through WebGL the game play runs ok however the video doesn't work. I get same error as OP.

 

Hey folks,
Just FYI, we did eventually get this working using h.264 and pointing at a URL instead of embedding the media in the WebGL app. Sounds like other folks are having other issues, but it's at least worth a try.

 

Can some one explain how you got this working please!
Do not know how to do:
"using h.264 and pointing at a URL instead of embedding the media in the WebGL app"

Thank you in advance.

Cheers

 

Been having the same problem! My video clip works in the editor, but when I build a WebGl and open it, no video plays. I have tried using URL's, VideoClips with Material Override and Render Texture and nothing has worked! I know with URLs you need an absolute path, but I don't know where to upload my videos to get that URL path. Then there were some mentions of using script to find the video, but I am not really a programmer.

Does anyone have any idea on what to do?

 

I know this is old. But, I still had the same issue so someone else might find this solution:

I used AWS to host it, followed their tutorial on activating AWS as CORS configuration and hosting a video. But, now I'm streaming from URL via webgl upload to itch.io.

I hope this helps someone else. So much relief. Took 5 minutes to implement the solution!

 

Did you ever find a solution to this? Having the same issue at the moment. Using the absolute path of a video file stored in a folder within my home directory seems to crash Unity.

 

the correct thing is that the developers of unity will find a solution for this problem
Sadly, it cannot be solved without knowing how to program ...
- To convert the video into "H264" in a simple and free way I use "handbrake"
- The video that results from the conversion, I put it in the folder "StreamingAssets" inside the "Unity"
- To play the videos I use the following line of code

Code (CSharp):

1.     public string folderName = "Videos";
2.     public string fileName = "";
3.     public string fileFormat = ".mp4";
4.     public VideoPlayer videoPlayer;
5.  
6.     void Start()
7.     {
8.         videoPlayer.source = VideoSource.Url;
9.         string filePath = System.IO.Path.Combine(Application.streamingAssetsPath, folderName + System.IO.Path.DirectorySeparatorChar + fileName + fileFormat);
10.         videoPlayer.url = filePath;
11.     }

 

[Unity 2020.2.5] Used the method from @JuanJSAR. Im putting the videos in the streaming assets folder and while it works in the editor it breaks when played through the firefox browser even when run directly with build and run. Error reads: No way to decode the file video/mp4.
What gives?

 

System.IO.Path.Combine() works with WebGL?
I thought System.IO is not supported.

i would replace this line with

Code (CSharp):

1. videoPlayer.url = Application.streamingAssetsPath + "/myvideofile.mp4";

 

please sir it doesn't work even in other browsers even chrome I used the same setup why won't a simple vodeo work I added a button so I can start and stop it no hope

 

@Thunderkilll I developed an asset that can play videos on webgl.

 

thank you man it is good since you know about it then how can I retrieve camera feed in webgl and send it with webRTC can you help me with that please .???

 

WebRTC is not covered by any of my assets. I suggest you look into this plugin instead.
