Unable to Play using ClearKey #780

AmarnathCJD · 2023-10-30T21:01:34Z

Hello,

I have a dash (mpd) DRM protected Video which Works well on JW test Stream site, But I was unable to get it working With ExoPlayer
All i get is A blank screen with time seeker at 4hours++ random time

FULL CODE: https://gist.github.com/AmarnathCJD/e575991991f0a2b6201398cc24221f7b

drmKey = "b8ed4930014a0ad8f4bc2310f378edd2"
drmKeyId = "89413479ba07590893320faf05a6b7fd"
mpdUrl = "https://bpprod3linear.akamaized.net/bpk-tv/irdeto_com_Channel_301/output/manifest.mpd"
header = ["host": "bpprod3linear.akamaized.net"]
No License server.

My Questions:

Is the Implementation correct?
How to pass custom header "host" during recieving the content

Current Error:
Playback error androidx.media3.exoplayer.ExoPlaybackException: Unexpected runtime error at androidx.media3.exoplayer.ExoPlayerImplInternal.handleMessage(ExoPlayerImplInternal.java:668) at android.os.Handler.dispatchMessage(Handler.java:102) at android.os.Looper.loopOnce(Looper.java:205) at android.os.Looper.loop(Looper.java:294) at android.os.HandlerThread.run(HandlerThread.java:67) Caused by: android.media.MediaCodec$CryptoException: Decryption Error: ERROR_DRM_NO_LICENSE

Failed on decrypt, error description:Status(-8, EX_SERVICE_SPECIFIC): '1: {"cdmError":1,"errorMessage":"Decryption Error"}

PS: sorry for such silly question, This was all i could makeup after hours of google search for documentation, its hard as most codes are of exoplayer2 and backwards compatablity of this lib is not that great:)

The text was updated successfully, but these errors were encountered:

This part is not correct. The JSON string you've contructed there is an online license key response, not an offline keyset ID (which you would have got from e.g. OfflineLicenseHelper.downloadLicense). I don't think most (any?) ClearKey DRM implementations support offline DRM licenses. You should remove this.

.setKeySetId("{\"keys\":[{\"kty\":\"oct\",\"k\":\"${encodedDrmKey}\",\"kid\":\"${encodedDrmKeyId}\"}],\"type\":\"temporary\"}".toByteArray())

Your .setKeyRequestParameters(...) call will have no effect because you're using LocalMediaDrmCallback (i.e. no key request will be sent to any DRM server, so there's no request to attach these parameters to).

Why do you create two separate MediaItem instances, one with C.CLEARKEY_UUID and the other with C.WIDEVINE_UUID? It looks like the C.WIDEVINE_UUID is the one actually being used for playback, so it's not surprising it doesn't work when combined with your DefaultDrmSessionManager that you've configured to work for C.CLEARKEY_UUID.

Similarly, it seems your defaultHttpDataSourceFactory, dashChunkSourceFactory, manifestDataSourceFactory, and dashMediaSource locals are never actually used for playback (since when calling player.prepare you construct a new MediaSource instance without using any of these locals).

Why do you need MergingMediaSource if you're not merging it with anything?

You may find the code looks a bit simpler if you use Player.addMediaItem APIs and avoid manually constructing MediaSource instances. You can instead provide a custom MediaSource.Factory to the player so it can create the MediaSource instances internally: https://developer.android.com/guide/topics/media/exoplayer/media-sources#customizing-media-source-creation

AmarnathCJD · 2023-10-31T14:16:53Z

May I get a simple Player.addmediaitem example with clearkey and clearkeyiD please

(,just this part)

It's a bit confusing

icbaker · 2023-10-31T14:35:27Z

Something like this, untested, and in Java rather than Kotlin

String clearkeyJsonResponse = "TODO";
DrmSessionManager clearkeyDrmSessionManager =
    new DefaultDrmSessionManager.Builder()
        .setUuidAndExoMediaDrmProvider(C.CLEARKEY_UUID, FrameworkMediaDrm.DEFAULT_PROVIDER)
        .build(
            new LocalMediaDrmCallback(clearkeyJsonResponse.getBytes(StandardCharsets.UTF_8)));
ExoPlayer player =
    new ExoPlayer.Builder(/* context= */ this)
        .setMediaSourceFactory(
            new DefaultMediaSourceFactory(/* context= */ this)
                .setDrmSessionManagerProvider(mediaItem -> clearkeyDrmSessionManager))
        .build();

String mpdUrl = "TODO";
player.addMediaItem(
    new MediaItem.Builder()
        .setUri(mpdUrl)
        .setDrmConfiguration(new MediaItem.DrmConfiguration.Builder(C.CLEARKEY_UUID).build())
        .build());

I can't access your MPD linked above (403 error), but you may want to check that your ClearKey <ContentProtection> nodes contain the required default_KID attribute. See also google/ExoPlayer#9169 (comment).

AmarnathCJD · 2023-11-02T06:45:25Z

Ok I'll get back to you:) thanks for such quick replies

I have checked this and it existsit exists like

ContentProtection enic:default_KID: value

icbaker · 2023-11-02T14:36:19Z

I'm going to close this because without access to the media there's no further assistance we can really offer (we're just guessing at potential causes at this point, which isn't a great use of time).

https://media.axprod.net/TestVectors/v7-MultiDRM-SingleKey/Manifest_1080p_ClearKey.mpd

This manifest includes a license server URL as documented here: https://github.com/Dash-Industry-Forum/ClearKey-Content-Protection#workflow

This means it shouldn't need a LocalMediaDrmCallback implementation and can instead use the default HttpMediaDrmCallback implementation. However I tried this by playing it with the demo app and requesting the DRM license failed with a certificate error (i.e. this content isn't really completely playable/valid):

Exception in CronetUrlRequest: net::ERR_CERT_DATE_INVALID, ErrorCode=11, InternalErrorCode=-201, Retryable=false

I logged the JSON license request that would have been sent:

{"kids":["nrQFDeRLSAKTLifXUIPiZg"],"type":"temporary"}

It seems in your hard-coded JSON response you've mixed up the kid and k attributes:

{\"keys\":[{\"kty\":\"oct\",\"k\":\"nrQFDeRLSAKTLifXUIPiZg\",\"kid\":\"FmY0xnWCPCNaSpRG-tUuTQ\"}],\"type\":\"temporary\"}

Fixing this and using LocalMediaDrmCallback with this JSON string makes the content playable:

{\"keys\":[{\"kty\":\"oct\",\"k\":\"FmY0xnWCPCNaSpRG-tUuTQ\",\"kid\":\"nrQFDeRLSAKTLifXUIPiZg\"}],\"type\":\"temporary\"}

Closing as I believe this resolves the question.

I was able to play that public source using this but the one i started this question intially withis still unplayable with error:
