registered dynamic events prevent playing a video

[ThijsBoeree]

Hi,

I am busy buildin a seperate video player, and want to control it via a main VI. The wierd thing is: when i make where i have the controls on the video player, it plays the vide (H.264) but when i register events (dynamically) and play it via my main VI, the playbutton is working, i can see the progresbar on the WMP player, but the screen stays black?

Best reagrds,

Update your graphics card driver, that might help.

In the absence of any more information I'm afraid I can't help any more than that.

Thanks, but it doesn't help?

When i just connect a boolean dynamically to open a video file it works fine, but the moment i use the control of the "play" button, the WMP player screen goes black? I really don't understand?

You provide no code.

I can provide no help.

These two things are related.

Hi,

The settings for the media player Front panel objects are not the same.  One of them has the "Windowless Video" set to true, the other to false.  I've no experience with this particular item, but I would first copy the actual control fromt he working VI to the not working VI and see if it suddenly works.  You can right-click on them and select "Property browser" to see the custom properties of the palyers.

I really don't understand!!

But now it works??

Thanks for the help! Now let's see how long it will work!

Right-click on the video players and select "Property Browser".  You will see that the object has several properties of its own which are seperate to LabVIEW.  Doing this for both versions of your players show different settings for the various properties meaning that one of them was simply configured wrong.

Hi,

I figured it out! When i set the visibilty on "false" (from the media player) and then back on true again, the video won't show....? It could be a flaw from WMP?
