VP9 Videos are broken on Intel builds

[GreyAsteroid]

System and IINA version:

• macOS 12.2
• IINA 1.2.0 Build 129

Expected behavior:

IINA is able to play VP9 video files.

Actual behavior:

IINA displays nothing and freezes if play/pause is pressed.

Steps to reproduce:

1. Use a build of IINA that includes FFmpeg 5.0
2. Use an Intel based Mac
3. Wallow in sadness as you can no longer play VP9 videos.

• [X] MPV does not have this problem. (If using pre-5.0 FFmpeg)
• [X] Official IINA does not have this problem.

This is actually an FFmpeg issue that's affecting IINA since it defaults to hardware acceleration being enabled.

I don't have an Intel based Mac device.

Does disabling hardware acceleration in preference work for you?

[GreyAsteroid]

Yes, disabling hardware acceleration stops the issue from occurring.

[CarterLi]

Well, I can't do anything except waiting for ffmpeg fixing this issue. Let's disable hardware acceleration for now or just stuck at the latest build with ffmpeg 4
