Question

Hello, Bitmovin Flutter team.
We want to play DRM Contents on Flutter project.
While playing DRM videos on iOS I am facing this error. The video is encoded via Pallycon. It works perfectly fine on Android.
But we can’t play DRM contents on iOS.

I developed drm configuration on flutter. (Please see below code)

And I gave you detail error message

[BMP] [Source] [Error] Content key request failed with error: The operation couldn’t be completed. (OSStatus error -42681.) [Data code: -42681, message: The operation couldn’t be completed. (OSStatus error -42681.), underlying error: Error Domain=NSOSStatusErrorDomain Code=-42681 “(null)”]

I don’t know why “Source Error. This content is not authorized.” error.
Please check our problem.

Map<String, String> _fairPlayHeaders(String pallyconToken) {
return { 'pallycon-customdata-v2': pallyconToken,
        'Content-Type': 'application/octet-stream' };
      }

fairplay: FairplayConfig(
          licenseUrl: 'https://license.pallycon.com/ri/licenseManager.do',
          certificateUrl:
            'https://license-global.pallycon.com/ri/fpsKeyManager.do?siteId="AAAA',  // (`AAAA` is example)
          licenseRequestHeaders: _fairPlayHeaders(token),
          certificateRequestHeaders: _fairPlayHeaders(token),
          prepareContentId: (contentId) {
            return contentId.substring(cId.indexOf('skd://') + 6);
          },
          prepareCertificate: (certificiate) {
              print("=> Certificate $certificiate");

              List<int> decode = base64.decode(certificiate);
              Uint8List bytes = Uint8List.fromList(decode);
              String result = String.fromCharCodes(bytes);

              return result;
            },
            prepareLicense: (license) {
              print("=> License $license");

              return license;
            },
            prepareMessage: (spcData, _) {
              // spcData, assetId
              print("=> Message $spcData");

               return spcData;
            },
        ),

Hi @luna , thanks for reporting the 42681 error code you’re facing, which seems to originate at Apple Native player layer (not Bitmovin) and has also been reported by other non-Bitmovin users on threads like:

At first glance it seems related to the way keys are processed and handled, rather than to a specific client SDK. Hence, the troubleshooting steps I’d recommend are:

1.- Ensure that this sample web implementation works ok for you on any Safari-iOS environment:

2.- Then replace with your own content and verify it still plays ok

3.- Finally, translate the working code on web to your Flutter implementation
