Stremio Platform
Android TV
Describe the bug
HDR/HDR10+ to SDR Transition Issue with Media3/ExoPlayer. The Stremio enters correctly in HDR/HDR10/HDR10+ but fails to return to SDR once the the playback is stopped.
Why not using VLC/MPV? the first has issues with audio, the second has terrible tone mapping. EXO is way better in everything point blank.
this is the short version of the story. long version below:
I am experiencing an issue when switching from HDR/HDR10+ video playback back to SDR on an Android TV box connected to a 4K QLED display.
The display supports HDR, HDR10, HDR10+, and HLG. The issue occurs specifically when playback is handled through Media3/ExoPlayer.
WHAT HAPPENS
With Media3/ExoPlayer, after starting to play H* material it goes from SDR to H* no issue, the HDR output state does not return to SDR. The display remains in HDR instead of correctly switching back to SDR.
This behavior is consistent and reproducible when using Media3/ExoPlayer, Tested also with Just (Video) Player which uses Media3 aswell
COMPARISON WITH OTHER PLAYBACK ENGINES
I tested the same type of HDR → SDR transition using different playback engines.
Two different YouTube 3rd party applications were tested, and the problem did not occur. HDR content could be followed by SDR content without the HDR state becoming stuck.
Kodi was also tested with an HDR10+ sample. Kodi correctly returned to SDR after HDR10+ playback.
OBSERVED BEHAVIOR
YouTube app #1:
HDR/HDR10+ → SDR: Works correctly
HDR state: Correctly returns to SDR
YouTube app #2:
HDR/HDR10+ → SDR: Works correctly
HDR state: Correctly returns to SDR
Kodi:
HDR/HDR10+ → SDR: Works correctly
Frame-rate switch: Yes
HDR state: Correctly returns to SDR
Stremio / Media3:
HDR/HDR10+ → SDR: Fails
Frame-rate switch: Yes
HDR state: Remains in HDR
Just (Video) Player / Media3:
HDR/HDR10+ → SDR: Fails
Frame-rate switch: Yes
HDR state: Remains in HDR
PLEASE FIX, EXO PLAYER WHICH IS CLEARLY FAR BETTER THAN THE OTHER ENGINES AND PLAYERS.
