Videos compare a la VMRPlayer SDK



Frage von Frank Derlin:
Dezember 2008

Hello together,
I am looking for a possibility of two technically kompfortablere
fundamentally different videos (eg AVI and MPEG2), synonymous
different length, to compare visually.

What I mind is / was in the form of samples in the DirectX
SDK: ...DXSDK/Samples/C/DirectShow/VMR9/VMRPlayer.
With the tool, you can watch the videos stored on and / or eg. over -
each other (1. top video, 2nd video down in the same window) play.
The catch of it is the middle of the videos I do not synchronize
may, if the videos as. scene-wise, or only by a single
Picture differ.
With the source code I did not climb through to make it for my purposes
transform.

Or in the variation in CodeProject/DirectShowVMR9_demo.
No possibility of synchronization.

I know Avisynth / Stack Horizontal (Vertical).
Too complicated, because any change in the script (trim) a reload of the
Videos implies.

There are (at least two) Player Programs in the field of sport.
Some golf or tennis, for example. the movements of the player to analyze.
For me either inappropriate, too expensive, or via credit card
pay.

Nätürlich there is even more synonymous "Cutting programs", (with me here
MainActor) with the possibility of the videos in the timeline to move.

Short speech Langer sense, what I know is not enough for me,
thus reasonably easy to "work".

How it compares your videos?

Gruß, Frank

Well, it seems as if I am not around to Avisynth. Why should one
the wheel again invent. Me, then I must build something themselves.
*. avs with Play Sample Window "link and use something as a basis:

And to build a GUI, which seems to me the Trim () something pleasant
and combines the four issues. Perhaps with dual Seek "Slider.
