2 years ago Hi, thanks for submitting issues. Is it for any videos or one? Could you please share? Or check sample ones, which reproduces. you could also check if it is rendering issue, by QVideoFrame f = videoFrame; f.toImage().save("frame.jpg") and see if it is valid frame.

I tried the default video and two my own videos, and none of the videos can be played.
I tried to save the video to images with variable videoFrame or variable f, and all of them are valid frame.

Yes, may be it related to Mac M1. But I have no clue to debug it. Any suggestions?

2 years ago suggestion to test this file in QML Video/MediaPlayer from QtMultimedia and make sure that it works there.

2 years ago I also have an M1 Mac that suffers from the same issue. Is there anything I can do or any information I can provide that would help?

QtMultimedia examples provided by Qt team works fine. I am looking into the issue, but it's somewhat difficult and I have been busy these days. I'll try to solve it in July (If this issue still exist at that time

Found at least 2 issues, like wrong textures used, and need to figure out why MTLTexture is not enough for RHI. Also why RGB32 frames are not rendered properly. In this case it should be possible to convert to proper format.

The qml_video demo cannot play video, when running on MacOS M1. With debug mode, the play just flicks and shows pink image as attched, also ouputs the following message. I builds the project with cmake and QT_AVPLAYER_NO_HWDEVICE=1.
