Thanks - please can you add an EventLogger (https://developer.android.com/media/media3/exoplayer/debug-logging) and reproduce and take a new BR.

Please can you also provide a BR of a successful playback using 1.3.1, so we can understand what might be behaving differently.

Updated, please check

Thanks - I can't see any EventLogger output in the BR, so I'm not sure if you added it correctly (you need to add a line like player.addAnalyticsListener(new EventLogger())).

However I can see a difference between the two BRs without this, that I suspect is responsible for the error you're seeing.

At 1.3.1 we are instantiating an "insecure" (i.e. not HW-secure) video decoder:

OMXMaster: makeComponentInstance(OMX.MTK.VIDEO.DECODER.AVC) in mediacodec process

At 1.4.0 we are instantiating a HW-secure one (note the .secure suffix):

OMXMaster: makeComponentInstance(OMX.MTK.VIDEO.DECODER.AVC.secure) in mediacodec process

ClearKey doesn't support HW-secure playback.

At a guess, I suspect the change in behaviour might have been introduced by c872af4 where we switched from using MediaCrypto.requiresSecureDecoderComponent(String) to MediaDrm.requiresSecureDecoder(String).

We made a related follow-up fix/workaround that was included in 1.4.1 where MediaDrm.requiresSecureDecoder(String) was returning false when it should have been returning true (and MediaCrypto.requiresSecureDecoderComponent(String) was returning true): b184677 (and then a follow-up fix to this for an edge-case that will be in 1.5.0-beta01: 0b86f89).

In your case, my hypothesis would suggest that MediaDrm.requiresSecureDecoder(String) is incorrectly returning true while MediaCrypto.requiresSecureDecoderComponent(String) is returning false. Would you be able to test this hypothesis?

If you have a local dependency on ExoPlayer this is quite easy, because you can just add some logging here in MediaCodecRenderer:

media/libraries/exoplayer/src/main/java/androidx/media3/exoplayer/mediacodec/MediaCodecRenderer.java

Lines 579 to 584 in be4d31b

	boolean mediaCryptoRequiresSecureDecoder =
	codecDrmSession != null
	&& (codecDrmSession.getState() == DrmSession.STATE_OPENED
	|| codecDrmSession.getState() == DrmSession.STATE_OPENED_WITH_KEYS)
	&& codecDrmSession.requiresSecureDecoder(
	checkStateNotNull(inputFormat.sampleMimeType));

Something like:

if (codecDrmSession != null 
    && (codecDrmSession.getState() == DrmSession.STATE_OPENED
        || codecDrmSession.getState() == DrmSession.STATE_OPENED_WITH_KEYS)) {
  Log.w(
    "issue-1732",
    "drmSession.requiresSecureDecoder()="
        + codecDrmSession.requiresSecureDecoder(checkStateNotNull(inputFormat.sampleMimeType));
}
if (mediaCrypto != null) {
  Log.w(
    "issue-1732",
    "mediaCrypto.requiresSecureDecoderComponent()="
        + mediaCrypto.requiresSecureDecoderComponent(checkStateNotNull(mimeType));
}
