frameReady vs. overlayCallback

[Pixel]

1. When the sink type of grabber is set to be avi, is the frameReady function called for every frame written into the AVI ? If I want to stamp every frame going to the AVI file, do I have to use overlaycallback instead?

2. Can I add a listener to the grabber which is set to be an AVI sinker?

Thank you

Hello,

The frameReady callback is not available while using an AVI sink. This is because there is no mem buffer collection in this mode.
You can use the overlay callback instead.
