joeymalek on "core support of autostart, preload attributes"

Hello and welldone to wordpress for supporting html 5 media playing natively.
I yet did not use these new wp features and continued to use earlier plugins only because wordpress core does not support the autoplay and preload attributes for html 5 video/audio media.
I am posting this on purpose here because I expect this to be made available unless I missed to find it so far. I believe it needed by the community to have the wordpress core html 5 media player supporting video autostarting when the visitor arrives on the page. Thanks in advance to all of you contributing to make this happen.
