* vo_opengl: hwdec_osx: use new format setup functionwm42017-02-171-1/+0
| | | | | | | | | | | | | | | | We can drop the custom table. For some reason, the interop does not accept GL_RGB_RAW_422_APPLE as internal format for GL_RGB_422_APPLE, so switch the format table to use GL_RGB (this way both interop and real textures work the same). Another victim of the apparent requirement of exactly matching texture formats is kCVPixelFormatType_32BGRA. vo_opengl wants to handle this as normal RGBA texture, with a swizzle applied in the shader. CGLTexImageIOSurface2D() rejects this, because it wants the exact internal format. Just drop the format, because it's useless anyway. (Maybe this is a bit too fragile...)
* videotoolbox: fix RGB formatwm42017-02-171-1/+1
| | | | | Wrong colors. This didn't matter for the OpenGL interop code, because the CV format was mapped to the correct texture format.
* videotoolbox: add reverse format mapping functionwm42017-02-171-5/+20
| | | | | Introduce mp_imgfmt_to_cvpixelformat(), and change the existing mp_imgfmt_from_cvpixelformat() to a table to avoid duplication.
* videotoolbox: factor some duplicated codewm42017-02-171-0/+60
The code for copying a videotoolbox surface to mp_image was duplicated (with some minor differences - I picked the hw_videotoolbox.c version, because it was "better"). mp_imgfmt_from_cvpixelformat() is somewhat duplicated with the vt_formats[] table, but this will be fixed in a later commit, and moving the function to shared code is preparation.
