Hi, I know that my solution is not effective but it works very well. so I gets frames from sdl_device . First I hide all windows by "SDL_HideWindow(strm->window);" in "sdl_create_rend()", then I gets frames by my own callback in method "put_frame(.)". To recognize which windows are for which calls (or maybe previews) I use SDL_GetWindowWMInfo(stream->window, &sysWMinfo) and then I send sysWMinfo.info.win.window in callback, where sysWMinfo is SDL_SysWMinfo. For me it's enough. I think that, you could use something similar to other devices. Or you can write your own devices which will be do itJ. it is highly likely, that there is a more efficient solution but I don't have time to find and testing it (maybe in vid_stream.c) Good luck Andrew -------------- next part -------------- An HTML attachment was scrubbed...
