Should m_videoRotation and m_videoMirrored be removed as well if they are no longer used except in implement videoRotation() and videoMirrored() that could return default values?
Or maybe add a FIXME to say that they should be removed at some point?

You could do  m_sample(WTFMove(sample)) next to m_presentationSize instead.
Then reuse m_sample instead of sample in the constructor body.

> Source/WebCore/platform/graphics/gstreamer/VideoFrameGStreamer.h:46
> +    RefPtr<JSC::Uint8ClampedArray> getRGBAImageData() const final;

Could be private?

> Source/WebCore/platform/graphics/gstreamer/VideoFrameGStreamer.h:52
> +    VideoFrameGStreamer(const GRefPtr<GstSample>&, const MediaTime& presentationTime, VideoRotation = VideoRotation::None);

Could be private?

Ah yes, I forgot to remove those.

Can we make the MediaTimes const &?
