* Software renderer
* -----------------
*
* MPV_RENDER_API_TYPE_SW provides an extremely simple (but slow) renderer to
* memory surfaces. You probably don't want to use this. Use other render API
* types, or other methods of video embedding.
*
* Use mpv_render_context_create() with MPV_RENDER_PARAM_API_TYPE set to
* MPV_RENDER_API_TYPE_SW.
*
* Call mpv_render_context_render() with various MPV_RENDER_PARAM_SW_* fields
* to render the video frame to an in-memory surface. The following fields are
* required: MPV_RENDER_PARAM_SW_SIZE, MPV_RENDER_PARAM_SW_FORMAT,
* MPV_RENDER_PARAM_SW_STRIDE, MPV_RENDER_PARAM_SW_POINTER.
*
* This method of rendering is very slow, because everything, including color
* conversion, scaling, and OSD rendering, is done on the CPU, single-threaded.
* In particular, large video or display sizes, as well as presence of OSD or
* subtitles can make it too slow for realtime. As with other software rendering
* VOs, setting "sw-fast" may help. Enabling or disabling zimg may help,
* depending on the platform.
*
* In addition, certain multimedia job creation measures like HDR may not work
* properly, and will have to be manually handled by for example inserting
* filters.
*
* This API is not really suitable to extract individual frames from video etc.
* (basically non-playback uses) - there are better libraries for this. It can
* be used this way, but it may be clunky and tricky.
*
* Further notes:
* - MPV_RENDER_PARAM_FLIP_Y is currently ignored (unsupported)
* - MPV_RENDER_PARAM_DEPTH is ignored (meaningless)
