Something like splitter tells exact resolution to the player and player do some scaling to accomplish this? So if original resolution is 640x360 and Display width/height is 1280x720, I should not be able to tell if the video is scaled from 360p on the fly or before encoding unless I look to some statistics?

The idea is indeed that the initial size of the video during playback is set to display width/height by the player (not the demuxer or codec though -- it is supposed to be up to the player so that the user still has the choice which scaling methods to use etc). It is not supposed to be a fixed size so the user should still be able to resize the playback window afterwards.

However, most players if not all only use the quotient "display_widht/display_height" as the aspect ratio for playback and determine the initial size themselves. Some muxing applications or users of those even go so far and use e.g. "16" for the display_width and "9" for the display_height parameter -- but this is mostly a result of the players not honoring the actual display width/height but only using its quotient for aspect ratio calculation.

If this is so, does haali splitter respects that?

I don't know, and like I said, it is supposed to be the player's job, not the splitter's/demuxer's/codec's. However, I'm not familiar with Windows' multimedia stack and cannot judge whether or not it would be easier to implement proper display width/height handling in the splitter itself.
