extract pictures from avi-videos with LabView

[Christoph Mönch]

hello,

ich möchte eine Videodatei (am Besten *.avi) in Labview einlesen. Sobald ein
bestimmter Zustand eintritt, muß der Ablauf unterbrochen werden und das
Bild,
das dem Zustand zugeordnet werden kann als Einzelbild (gif,
jpg,..)abgespeichert werden. Ist das mit Labview möglich?

I would like input a video file ( *.avi) in Labview, then under a
situation-initiated point take a frozen image of it and then save it as a
separate image (gif, jpg). Is this possible with Labview?

Yes, it is possible.

Check out Graftek on the web - they have an AVI toolkit for LabVIEW.

yes, it is possible to take a picture of the
avi frame and same it to jpg (labview supports no gif).

One possible way is to use activeX server(ms media player v7.0 and above) to play the avi,
then capture the front panel of the running vi, then cut out the part you need and save it to file.

another way is to write your own avi dlls to retriev a paritcular file and save it to file.

hello.

1) I would like input a video file ( *.avi or *.dat) in Labview, then under a
situation-initiated point take a frozen image of it and then save (or process its colors) as a
separate image (gif, jpg). Is this possible with Labview?
2) also I want to biuld a ROBoT that can recognize things
around it like a simple ball or cube.
but I don't have any idea how to do it by labview &
3) don't know any suitable and low cost webcam or a camera

guide me please
thanks a lot
