are you involved in refresh rate changer
Yes, dynamic refresh rate should analyize the media and choose 23 or 59 value to swtich the refresh rate.
is telecined? the Amd card user must set "pulldown detection" on Catalyst and MP set 23
is not telecined? the Amd card user can set "pulldown detection" on Catalyst (but will be ignored) and MP set 59
Ps. I think telecine video files must be Pretty uncommon?
Yes, There are not too much tv series in 1080i format but all of them are telecined (I guess)
This isn't the correct thread for discussing this, but:
MP dshowhelper/EVR Presenter does work out the actual video stream frame rate from the timestamps (this is the 'Detd FPS' in the render stats) and this information is available to the MP player code, but it can't do this until playback starts. So the refresh rate change would have to be delayed until after playback starts (and that can create problems with other filters, renderers etc.), Also there are video files with variable 'real' frame rates around....
