我正在 Exoplayer Android 上实现一个 OTT 应用程序。我们正在使用 Widewine DRM 保护我们的内容。但是我们收到如下所示的错误。

代码如下所示

drmSessionManager = null;
if (drmSchemeUuid != null) {
String drmLicenseUrl = ConnectPortalSettings.WIDEVINE_LICENSE_SERVER_URL;
String[] keyRequestPropertiesArray = new String[]{};
// drmLicenseUrl = intent.getStringExtra(DRM_LICENSE_URL);
// keyRequestPropertiesArray = intent.getStringArrayExtra(DRM_KEY_REQUEST_PROPERTIES);
try {
drmSessionManager = buildDrmSessionManager(drmSchemeUuid, drmLicenseUrl,
keyRequestPropertiesArray);
} catch (UnsupportedDrmException e) {
int errorStringId = Util.SDK_INT < 18 ? R.string.error_drm_not_supported

return;
}
}
@SimpleExoPlayer.ExtensionRendererMode int extensionRendererMode =

? (false ? SimpleExoPlayer.EXTENSION_RENDERER_MODE_PREFER

LoadControl loadControl = new DefaultLoadControl();
// 3. Create the player
player = ExoPlayerFactory.newSimpleInstance(this, trackSelector, loadControl,
drmSessionManager, extensionRendererMode);
} else {
LoadControl loadControl = new DefaultLoadControl();
player = ExoPlayerFactory.newSimpleInstance(this, trackSelector, loadControl);
}
请帮我解决这个问题。提前致谢。
最佳答案
转储中有很多数据可能会令人困惑和分散注意力，但您需要关注的错误是:
android.media.UnsupportedSchemeException: Failed to instantiate drm object
你是在模拟器上运行这个吗？ 您可能需要在真实设备上运行它才能进行测试。 在以下位置查看更多信息: https://github.com/google/ExoPlayer/issues/1616
如果您不是在模拟器上运行而是在设备上运行，则可能是您运行它的设备有问题，如下所示: https://github.com/google/ExoPlayer/issues/2260
另外，请注意，当我们关注该错误时，我们也认识到它是: UnsupportedSchemeException
Exception thrown when an attempt is made to construct a MediaDrm object using a crypto scheme UUID that is not supported by the device
