that's very unspecific. there are a bunch of examples for the current render API. here are few examples of updated examples/commits.

Looks like these are the only examples left that use the old API? https://github.com/mpv-player/mpv-examples/blob/master/libmpv/qml_direct/main.cpp https://github.com/mpv-player/mpv-examples/blob/master/libmpv/wxwidgets_opengl/main.cpp

Oh, and ios.

Well, after all, it's too much work. I removed them to avoid confusing new developers. I've also disabled the opengl_cb API in mpv git master (and the next release) to avoid that the API somehow keeps sticking around.
