[iOS] Paused video in the background is black when foregrounding app
https://bugs.webkit.org/show_bug.cgi?id=275381
rdar://121189961
Reviewed by Eric Carlson.
When moving to a background/non-visible state, the system will purge all
AVSampleBufferVideoRenderers
and AVSampleBufferDisplayLayers by destorying their associated video decoders.
And when the page returns
to a foreground/visible state, the paused video content is black/transparent.
Always update the current pixelbuffer when the video pauses, to ensure we
always have a pixelbuffer to
display when our renderers are purged. When we are notified that our renderers
require a flush to
continue decoding, set the last pixelbuffer as the contents of the AVSBDL. This
ensures there is
_something_ to display when returning from the background.
