Build Error

[ptrkrlsrd]

Hey,

When I'm trying to build my project I'm getting an error on line 42(in ofxAVFVideoPlayer.h) saying:
Virtual function 'getPixels' has a different return type ('unsigned char *') than the function it overrides (which has return type 'ofPixels_<unsigned char> &')
Am I doing something wrong?

The addon is quite old so I presume it was built for a previous version of OF. I will give it a try too and see if I can make it work

This problem is still present.

I'm using Xcode 7.3.1, openFrameworks v0.9.3. I'm just trying to open up the example.

I need to use newer openFrameworks versions because of another addon I'm using.

I'm on oF v0.9.8, also seeing this issue. It looks like it has something to do with an update to how video pixels are returned in newer versions of oF.

A similar issue popped up in ofxOpenCv. I dug up Arturo's commit that may have addressed the issue, notice that he gets rid of anything that uses ofPixelsRef and in the header changes return types from unsiged char* to ofPixels&.

Trying to see if I can implement similar changes in this addon, but not going very smoothly so far. Not exactly an oF ninja here but I'll submit a PR if I have any luck.

Not sure if this helps, but if something expects unsigned char * from an ofImage, you can do theImage.getPixels().getData().

getPixels() returns a reference, and getData() the old unsigned char *.

Awesome, thanks @hamoid!
