Question Unity video player is not working

Hello, I have a very unique issue. As far as I can tell I'm probably the only person with this exact problem. whenever I attempt to watch a second video in scene . weather it be via YouTube URL or an MP4 file I get the same error (video works on first attempt. After pausing and playing. It fails on the second attempt and any further attempts until I restart unity entirely)

WindowsVideoMedia error 0xc00d36b4 while reading C:/Users/johnb/My project/Assets/Galaga Walkthrough_Gameplay NES HD 1080p.mp4

Context: IMFSourceReader::WaitForSample in StepAllStreams
Error details: The data specified for the media type is invalid, inconsistent, or not supported by this object.

I'm using an older version of unity since VRchat requires you use unity 4.3 from 2019

Never the less. The issue occurs in game and in unity. while in game I can watch a single video per instance. But anything more and the video breaks. Same exact issue happens within a project while editing a world inside unity

This "unsupported video" nonsense can't be the issue. Because the video works on the first attempt. But won't allow a second playing of the same video.

What does it mean by "windows video media" what exactly is this? An application? Because typing that in results in nothing found. I thought it might be referring to windows media player. But that can't be it. I uninstalled and reinstalled it and no dice.

 

"but after pausing and resuming, the video would stop (crash, black screen?) and send the error mentioned. Am I right?"

Yes. But not pausing as in pressing pause. But rather going to play mode. Then back to edit mode then back to play mode (normal pause works)

Upon going back to play mode I get some 999+ errors (the one I posted above)

1.)Is it happening with every file or just with this one in particular? Can you try this video, for example?

Yes. With every file. And url that goes through the windows video media thing (I will test this video after work)

2.) Can you play the file in any other software like VLC or Media Player

Correct. I have tried them in these and it works with no issues

3.)Can you try reproducing the issue with a new empty project?

Will do this afternoon.

4.)Are you using the latest 2019.4+ version? If not, try updating it to the latest if you can.

Unsure. But I will check when I'm home!

5.) For testing purposes, can you try upgrading your project (keep a backup) to a more recent version (>2021.2)
Yes. I will do this.

Thank you. Please check back later for an update later

 

I downloaded the latest version of unity (Unity 2021.2.16)
and tested my original video as well as the test video you provided me. both times. the video works once you press play. but apon going back to edit. then back to play. i get this error message now

this error message is entirely different to the one from earlier.

as far as if im using the latest 2019 version. im not. VRchat is specific in that it uses a precise version. using later versions wont even let you upload to their servers so that rules out that possibility.

 

Thank you for the feedback. I'll try these solutions. Thank you!

 

Hi all
Is there a way to decode and understand videoplayer errors ?

 

Thanks for your answer !
My problem is that i cannot plmay mp4 from web.
This comes from my OS ( win7 ) on wich i updated the nvidia driver to the latest.

My app works fine on win10 bus as i still develop on win7, i was wondering what i was missing ( and to be honest i strictly don't understand all those media things, codecs, formats, etc....... )
Is there a 'basic standard' thing to install on windows to make simple standard ( audio and video ) things work ?

thanks and happy unitying !

 

Sure This is very kind of you !!!

The error i got in unity console is:

Hi.

I searched a bit on this MP4 problem..... Finally, i tried to open the big buck bunny MP4 video and.... It vorked



So i started to take a peek at my website server.... tried things in the htaccess.... And noticed my MP4s worked fine in http:// but not in https://

I'm still not sure of anything but maybe this is a clue to take in care ?

What is your opinion ?

EDIT: Back there with some more info.
definetely, this url:
http://kleioscope.fr/appmedias/carcass/_FR/bbb.mp4
works with the unity video player ( it is the big buck bunny video, for beeing sure it is not a f*cked-up mp4 )
And also, this url:
https://kleioscope.fr/appmedias/carcass/_FR/bbb.mp4
do not work in videoplayer with an error 0x80072f8f

Then i thought i could format the requested URL on my server side with the htaccess file, by detecting appmedias/carcass in the requested URL and transform https to http in the request.
This just don't work.

Therefore i guess the problem comes from the videoplayer in windows 7 ( note that any http or https URL works in windows 10 )

Any idea to solve this ?

EDIT2: for those wanting to give a try with my files on server, here's the small unity3D project:

 

Hi @DominiqueLrx Thanks for your answer !

Yes this is the info i found: wininet_decode_fail :/ however i was missing the 'connection reset' info....
My first thought was that this came from my win7 codecs....

The strange thing is that the U3D videoplayer use i make in my app was developped on the win7 machine i use ! :O
The point is that i recently updated my nvidia driver. And since then i cannot play those videos from web....
I tried many things with many codecs installers but there was nothing to do....

Yes my videos can be played in opera and firefox with no problems and i can also play big buck bunny videos in unity with http and https.....

Hmmm..... connection reset ???? :O
lemme try something....
I be back very soon with infos and with answers to your question

Have a nice day and happy unitying !

EDIT: Back there with infos on your video link:
It opens properly in opera and firefox but with unity3D 2022.1.6.f1 i have the same error:
WindowsVideoMedia error 0x80072f8f while reading https://www.file-examples.com/storage/fefb234bc0648a3e7a1a47d/2017/04/file_example_MP4_480_1_5MG.mp4

Maybe i should give a try to a unity3D update ?

EDIT2: update to 2022 LTS changed nothing and adds a bug: editor ALWAYS runs as admin ( when no admin flag of hub or editor is ON )..... Uninstalling :/

 

bumpies ?

 

I searched on every forum on internet and eventually end up fixing this by disabling cookies forwarding.

 

I had a Windows Update just before this issue started up for me today (yesterday as of writing) with the latest recommended for VRChat Creator Companion Unity version 2022.3.6f1 and updating all the SDK's and assets for the project.
I recall something about an HEVC update, to enable it for devices that didn't have a dedicated encoder, or something like that in the update and didn't pay much mind to it, but today I had 3 strange ones about ODBE and some others. Unity is the only application affected, which makes me wonder if there's a backend update that broke Unity's communication ability to Google's playlist service or something. (going off of the console error log)

I'll post what the console reports every time I try previewing my AudioLink settings with a Youtube URL in Unity Player
First I get this in the console:

• WindowsVideoMedia error 0xc00d36c4 while reading https://manifest.googlevideo.com/api/manifest/hls_playlist/expire/1714650681/ei/2SkzZoWiNMXYybgP77eggA4/ip/2600:6c44:6800:c8:a001:b002:c003:a5c4/id/4854dc6751973824/itag/95/source/youtube/requiressl/yes/ratebypass/yes/pfa/1/sgoap/clen=3879673;dur=239.676;gir=yes;itag=140;lmt=1706219798598696/sgovp/clen=1224232;dur=239.614;gir=yes;itag=136;lmt=1706220463514477/rqh/1/hls_chunk_host/rr5---sn-p5qs7n6d.googlevideo.com/xpc/EgVo2aDSNQ==/mh/bQ/mm/31,29/mn/sn-p5qs7n6d,sn-p5qlsn7d/ms/au,rdu/mv/m/mvi/5/pl/51/initcwndbps/1357500/spc/UWF9f4YS61oI2ZdO8tpMYcXQx1ygUy1ZyyJ4SVLo_fl6Wk3WAWzCEiQBdjpZ/vprv/1/playlist_type/CLEAN/dover/11/txp/4432434/mt/1714628685/fvip/3/keepalive/yes/sparams/expire,ei,ip,id,itag,source,requiressl,ratebypass,pfa,sgoap,sgovp,rqh,xpc,spc,vprv,playlist_type/sig/AJfQdSswRAIgRP1nSxr_4sdeF1Vn4UG0U1RlpUgLBUT80vjZ69dwowMCIBFagXC2NMhNUk_aIHLBVxFHG9BIlu-iV_dK_u6wkrUB/lsparams/hls_chunk_host,mh,mm,mn,ms,mv,mvi,pl,initcwndbps/lsig/AHWaYeowRAIgYTHtoOuiup6u-vO_iAeoZ3c8Y5AhO8Mz0YqPOsy-2Z0CIAtelVokYygWSLzByMXUMNuvQ-4DomnkCqruPNubL_c1/playlist/index.m3u8

I haven't the remotest clue as to where to start, I've been across the horizon on Google and back downloading updated VLC players, codecs, and ultimately landed here and tried the cookies forwarding "fix" from the post above by @Smallu3755, and still no resolution. I've already restarted my PC once, earlier, I even ran SFC /scannow in an elevated terminal.

any help would be great!

Additional info:
Using the links above I was able to download the default AudioLink prefab link URL just fine, and then play it just fine.
