public static class AVCodecContext.Draw_horiz_band_AVCodecContext_AVFrame_IntPointer_int_int_int
extends FunctionPointer

If non NULL, 'draw_horiz_band' is called by the libavcodec decoder to draw a horizontal band. It improves cache usage. Not all codecs can do that. You must check the codec capabilities beforehand. When multithreading is used, it may be called from multiple threads at the same time; threads might draw different parts of the same AVFrame, or multiple AVFrames, and there is no guarantee that slices will be drawn in order. The function is also used by hardware acceleration APIs. It is called at least once during frame decoding to pass the data needed for hardware render. In that mode instead of pixel data, AVFrame points to a structure specific to the acceleration API. The application reads the structure and can change some fields to indicate progress or mark state. - encoding: unused - decoding: Set by user.
