@hongfeih Could you try to capture a full bugreport and not just the log output?

@paf-wv Please take a look. It looks like a device issue where the device can't handle the change in resolution.

[tonihei]

We will push a workaround which forces to use Widevine L3 on this device. Though not ideal, it helps to get around this issue.

[paf-wv]

@hongfeih have you been able to play back clear content of the same encode that was WV DRM protected? Just trying to determine if it is a platform issue that fails on resolution change as @tonihei pointed out.
Also, I have asked for a rep to reach out to Asus for assistance.

Not sure if this is clear already, but since the output paths are different for non-secure and secure playbacks, I think it's possible for issues around resolution changes to only affect one path or the other (and I think we've seen this on other devices in the past).

@paf-wv we've tried clear contents in exoplayer demo, all worked. And we saw playback of first 10 seconds clear content of that DRM protected stream.
@ojw28 I think you're right, Will try this, but no way to fix it instead of a workaround?

[ojw28]

We've forced this device to L3. Unfortunately I think that's the best we can do, unless Asus OTA the device.

[paf-wv]

Asus confirmed no new OTAs.
