[nolsqn]

hi all

is there a way to get a *.mkv extension video file in labview?

i know that *.avi video file , by using the vision toolkit , can be used in labview ...but is there a way to do the same thing with a *.mkv file

You can use ActiveX and a media player application. I have used this method on VLC player, Quicktime, and Windows media player. I can not promise you success but it is worth a try.   

Do a search in this forum for more details

Integrating a media player through ActiveX as already suggested, who understands that format is your best and probably only workable bet.

USe the vlc player and since vlc plays mkv (I can assure you that) i think it should work.

In a raw video format which I think your are implying by avi by saying that you can get at individual frames then this is fair enough.  However isn't mkv a compressed format i.e a key frame then information regarding how the the next 10/20 frames are processed?  i.e it creates the frames on the fly.  To get at that raw data you would need to convert it to a raw format first.  If you want to just play the file then i would recommend VLC.

Its like the difference between a wav file and an mp3 file.

Not that it is important. But you are wrong. The mkv file format is a container format. Here is a crash course in the mkv file format
