Native out of memory on playing 4k video on AFTMM

[PratimMallick]

[REQUIRED] Issue description
Player stops playing with out of memory in native while playing 4k content (DASH) on AFTMM firestick. This stream is encoded using h265, so it is using the hevc decoder. From the logs it looks like a native out of memory happened when GraphicBufferAllocator tried to allocate memory

[REQUIRED] Reproduction steps
Play the 4k content using exo sample app. This issue only happens when switching between 2160p and 1440p. Happens sometimes while going from 1080p to 1440p layer too.
Chances of getting this error increases when seek is done multiple times or incase of network fluctions. Either ways it looks like this issue comes when there is layer change. We get the following logs from the java layer

For the record, this asset will reliably reproduce with the demo app on 2.15.1 using AFTSS running 7.2.4.2:

 {
    "name": "Philo",
    "samples": [
      {
        "name": "Unencrypted with drm_session_for_clear_content",
        "uri": "https://www.philo.com/storage/dev/seth/aftss/decrypted.mpd",
        "drm_scheme": "widevine",
        "drm_license_uri": "https://proxy.uat.widevine.com/proxy?provider=widevine_test",
        "drm_session_for_clear_content": true
      }
    ]
  }

If we do not initialize a DRM session, the asset will play through just fine.

I've got the same problem with 4k fireTV sticks gen 2018. Do you know if there is a solution?
