1225 * information from the old QuickTime carbon api ( time code information as well as fps, etc.).
1226 * However, the QTKit devs at apple were not really big on documentation and further ...
1227 * QuickTimes ability to playback HB's largely variable framerate output makes perfectly frame
1228 * accurate information at best convoluted. Still, for the purpose of a custom hud based custom
1229 * playback scrubber slider this has so far proven to be as accurate as I have found. To say it
1230 * could use some better accuracy is not understating it enough probably.
1231 * Most of this was gleaned from this obscure Apple Mail list thread:
1232 * http://www.mailinglistarchive.com/quicktime-api@lists.apple.com/msg05642.html
1233 * Now as we currently do not show a QTKit control bar with scrubber for display sizes > container
1234 * size, this seems to facilitate playback control from the HB custom HUD controller fairly close
1235 * to the built in controller bar.
1236 * Further work needs to be done to try to get accurate frame by frame playback display if we want it.
