Does any1 know about the colorspace of the Apple H.264 Quicktime trailers ? I believe its YV12...i.e..4:2:0 but still if some1 has some confirmation on this then pls share it. Moreover, if the colospace is either YV12 or RGB, then what matrix is implemented in such videos: Rec709 or Rec.601 ? I hav posted this query in Doom 9 forum also but no one seems to have any clue about this, so i guess some1 might have any answer in this forum .
