   I've read through this entire thread (trying to follow as much as I can), the Google docs on scoped storage, and other issues and stackoverflow posts and I'm still not 100% sure that this issue applies to me, so if anyone can tell me I'd really appreciate it...
   
   For a feature I'm working on (involving opening a video, overlaying text on it with canvas, and capturing the output) I need the video and page to be same origin. So I've tried to use API30 and cordova-android@10.0.1 for the WebViewAssetLoader functionality to serve my app from https://localhost.
   
   The problem I have is that after updating (from API29 / cordova-android@9.1), when I select a video from the photo library, using previously working code like this:
   
   ```
             navigator.camera.getPicture(
               file => {
                 file = file.indexOf('file://') === 0 ? file : 'file://' + file
                 window.resolveLocalFileSystemURL(file, (fileEntry) => {
                   this.video = fileEntry.toInternalURL() // Vue.js data property that populates video src
                 })
               },
   
               () => {},
   
               {
                 destinationType: Camera.DestinationType.FILE_URI,
                 sourceType: Camera.PictureSourceType.PHOTOLIBRARY,
                 mediaType: Camera.MediaType.VIDEO
               }
             )
           }
   ```
   ... I get an error like this in the console:
   
   `GET cdvfile://localhost/sdcard/DCIM/Camera/VID_20210802_200106.mp4 net::ERR_UNKNOWN_URL_SCHEME`
   
   If I go back to API29 / cordova-android@9.1 it works fine again.
   
   Where I'm not sure if this is the same issue is from comments like this one by @HarelM https://github.com/apache/cordova-plugin-file/issues/426#issuecomment-751977160 :
   
   > @Vatsov Are you reading a file a user selects? If so I don't think there's an issue that is related to Android 11, or at least I hope not as you open the file picker and this should be OK even in Android 11 as far as I know.
   
   ...and things that I read in google's docs that seem to suggest that reading the users photo/video library is treated differently to accessing other types of file.
   
   Regardless, I've still tried adding the MANAGE_EXTERNAL_STORAGE permission, but that hasn't seemed to have any effect.
   
   So can anyone tell me if this is the same issue? Or is it a different one caused by the upgrade to API30 and/or cordova-android@10.0.1 ?
   
   To be honest I'm feeling a little out of my depth here and would very much like to get back to my cosy javascript safe place! :)
   
   Thanks in advance for any help or suggestions!
