GLES support for YUV

is there a support in GLES for processing YUV frames directly (input YUV, and output YUV) , If yes can someone explain which extension/API’s can I use to achieve this ?
basically my intention is to do post-processing tasks (e.g., scaling, cropping, color conversion, blending, additional image processing steps, etc.) using GLES

GL_EXT_yuv_target and GL_APPLE_rgb_422 appear relevant, although I haven’t tried using either.
