After restart macOS, Safari/Google Chrome cannot play embedded videos.
But...
In macOS I opened Finder and located a mp4
file, press space to quick view the content. I got a blank window with a loading icon. (This video can be played in this way yesterday.)
I use ctrl+click and select Open with
, use QuickTime to play it. But QuickTime responded an error said The document "xxxx" could not be opened. An unknown error occurred (-101)
.
Original question
Safari/Google Chrome cannot play embedded videos in website. I can see the 1st frame of the video and I can drag the progress bar to move the timeframe, it shows the frames. But when I clicked play button the video does not get played.
In Google Chrome I have tried:
- Disabling the hardware acceleration.
- Disabling the Ad Blocker.
- Clearing the browser data.
- Disabling the QUIC protocol.
In Safari I have tried:
- Allowed auto play for videos with sounds
The websites in question are not using Flash, just HTML5 video.
I am running macOS High Sierra 10.13.3 with Google Chrome 66.0.3359.45 (beta-64bit) and Safari 11.0.3.
