Attached is the clean patchfile. I want to give some small background:
the problem happens in javacpp. It looks like there is a problem
handling pixelformats not correct at all when used for pixel grabbing.
This is why I mentioned it in a streaming context.
However this patch is a small workaround to this and really minimal. We
will look more deeply into the wrapper to get rid of it but in the
meantime
Thanks

The problem is this warning is flooding the console with deprecated
warnings for every decoded frame. However decoding works well. This is
an issue with an Axis camera H264 stream received via rtsp for instance.
There are several complaints about it in the WEB for years now and I
could not find a real solution for the underlying problem. It looks like
vendors are not changing their encoding easily. ;-)

I'd rather have if we finally stopped using these pixfmts. They cause
nothing but problems to me.
