            files.removeWhere((v) => v.key == tmp.first.key);
          case TDUploadType.replace:

Start with the TDUpload implementation and the demo APK, using the supplied mediaType: video example on Android 15. Trace why selection falls back to images, then verify that video-only selection works in both the demo and the reported configuration.
