MEDIA / renderType / impossible to use custom renderType for video

[georgringer]

the if structure on line 178 (and following) in sysext/frontend/Classes/ContentObject/MediaContentObject.php always sets $renderType to 'swf',
so it’s impossible to use a custom renderType for video

the problem (imho) is the combination of

178 if ($renderType !== 'qt' && $renderType !== 'embed' && $conf['type'] == 'video') {
and

192 } elseif (isset($conf['file']) && !isset($conf['caption']) && !isset($conf['sources'])) {
193 $renderType = 'swf';
as a result $renderType is always 'swf' for video
or do I miss something here (guess not)?
