Screen recording can't be opened natively on Mac

[timja]

Jenkins and plugins versions report

What Operating System are you using (both controller, and any agents involved in the problem)?

Reproduction steps

Open a ui-recording.mov from a test result
If you're on mac it will default to quicktime player, it fails to open

Expected Results

It opens

Actual Results

It doesn't

Anything else?

I'm using VLC to open them currently which works but it's the only thing I need VLC for these days...

Code is around here:

acceptance-test-harness/src/main/java/org/jenkinsci/test/acceptance/recorder/TestRecorderRule.java

Lines 72 to 87 in 200aafd

	String mimeType = FormatKeys.MIME_QUICKTIME;
	String videoFormatName = VideoFormatKeys.ENCODING_QUICKTIME_ANIMATION;
	String compressorName = VideoFormatKeys.COMPRESSOR_NAME_QUICKTIME_ANIMATION;
	Dimension outputDimension = gc.getBounds().getSize();
	int bitDepth = BIT_DEPTH;
	float quality = QUALITY_RATIO;
	int screenRate = FRAME_RATE_PER_SEC;
	Format outputFormatForScreenCapture = getOutputFormatForScreenCapture(videoFormatName,
	compressorName, outputDimension,
	bitDepth, quality, screenRate);
	this.screenRecorder = new JUnitScreenRecorder
	(gc, gc.getBounds(), getFileFormat(mimeType),
	outputFormatForScreenCapture, null, null, diagnostics);
	this.screenRecorder.start();

Found a blog post that's newer than our code here which may have some updated format:

You can not open it natively on Windows either and am also using VLC to view them.
