how remove alpha channel

[Potoman]

Hello !

I'm a little lost on the goal of "videoconvert".

Does it allow to remove channel ?

In fact, I have a filesrc how load a png image.
By pngdec and imagefreeze I create a video flux with 25/1 framerate.

After that, I make some snapshot of the pipe and that's work perfectly.

But my caps is ARGB.

I really need to have RGB caps for the end flux.

I try :

filesrc location=plop.png ! pngdec ! imagefreeze ! videoconvert !
video/x-raw format=RGB ! appsink

But that doesn't work !

Someone can help me ?

Thanks.
