I was wondering what output is connected to this? Is it a PlayerView? Can you help me double check a few things, adding logs to show the variables related to resolutions at and And log if this line is executed: |

Hi @claincly!
Yes, defined very simply: <?xml version="1.0" encoding="utf-8"?>

@claincly, is there any other information I can provide to help debug this? Any ideas on if there is a work around? I tried sending the |

I wonder if you could log on this line? The resolution logs look correct. You might noticed some discrepancies between with/without video effects, but that's expected. |

Hi @claincly, here are some logs from in that method. Thoughts? |
|
Hmmm that is indeed very strange - I mean if I also noticed you mentioned you didn't try reproducing using the demo app, could you try using the demo app and see it reproduces? I just wanted to rule out any unrelated reasons. |

The no video issue is reproducible in the basic demo app with a change to import the I tried on another NVIDIA shield device (2017 model) and the issue is reproducible there as well. I also tried the Here is the patch just in case: diff --git a/demos/main/build.gradle b/demos/main/build.gradle

Interesting find. You are correct the debug preview is not a PlayerView (I think it's just a SurfaceView). The only difference I can think of is we call Although I don't recommend it, could you try commenting that line out and see if the video plays? |

One last thing to try - Nvidia might have very customized OpenGL stack), Adding change the color to something like red in media/libraries/common/src/main/java/androidx/media3/common/util/GlUtil.java Lines 554 to 555 in c35a9d6 |
No change
Screen is still black! |
Version
Media3 1.4.0
More version details
Calling
player.setVideoEffects()with any effects or even an empty list results in no video (just black screen).I reviewed the requirements for this to work and they all seem met:
androidx. media3.ui.PlayerViewmedia-effectlib is addedplayer.getRendererand the only video one isMediaCodecVideoRendererprepare()I guess it must be a hardware decoding issue, but I'm not sure how to validate. There's nothing obviously erroring in the logs.
Bare-bones code that causes the issue:
Devices that reproduce the issue
Devices that do not reproduce the issue
Reproducible in the demo app?
Not tested
Reproduction steps
setVideoEffectson the ExoPlayer object (even with an empty list)Expected result
Video plays successfully with effects applied or if no effects added at least the video plays normally
Actual result
Video playback is a black screen.
Audio plays as expected.
