Observed Issues

1. The system player app decodes HDR10 normally.
2. Hardware decoding works properly with IJKPlayer. (https://github.com/bilibili/ijkplayer)
3. Hardware decoding via EXO exhibits anomalies, as described below:

Key Question

Is there insufficient support for Hisilicon's MediaCodec in EXOPlayer? ... Hoping to achieve correct HDR10 decoding on this device.

Limitation & Offer

Since ADB operations are blocked on this device, logcat logs cannot be provided. However, I am willing to assist with testing if needed.
