Hi, we have a video editor app and we use ExoPlayer as the video player. For some videos, we started getting black screen in ExoPlayer. After a long debugging, we found that loading RewardedAds on application start causes the problem. Because it looks like each RewardedAd instance reserves MediaCodec resources even though you do not display them. ( probably through ExoPlayer because we see Exoplayer logs)

On application start we were loading 3 RewardedAd instances and we get ExoPlayer black screen ( due to mediacodec decoder initialization error). When we load only 1 RewardedAd instance at the start instead of 3, the problem is gone.

Device: samsung | SM-J710FQ

Android: 8.1.0

ExoPlayer Version: 2.11.4

Firebase Core Version = 17.2.2

Firebase Ads Version = 18.3.0

THESE LOGS ARE FROM APPLICATION INITIALIZATION

Here there is no ExoPlayer etc in the app, just loading the landing screen, initializing the app, MobileAds library etc and loading 3 RewardedAds. As you see there are 3 MediaCodec related lines:
