I write a simple test case with libvlc to play a video, now i want to select the "windows GDI video output" when play media, is there some function like "libvlc_media_player_set_ ....." which can control the video output?
Thanks!

No. If you want custom rendering, use the custom rendering callbacks.

thanks you for your reply, Is it related "libvlc_video_set_callbacks (libvlc_media_player_t *mp, libvlc_video_lock_cb lock, libvlc_video_unlock_cb unlock, libvlc_video_display_cb display,....." ?
i am not sure which function work, to vlc media player, i can select the "windows GDI video output" in the tools->preferences->Video->Output item, then it can play the video on multi-screens smoothly, how can i implement it to select ""windows GDI video output" with libvlc sdk, can you give me some examples? Can you please supply more details? Thanks again!

you could look this:

thanks for your information.
I notice there is wingdi, direct3d, directdraw module under video_output folder of plugins, is there a exposed api that i can invoke directly to select the output style, or i have to implement like the link you supplied?

You could get sources of existing video output plugins and reuse it. But you have no access to them via libvlc api as I know.

Do you know change which part of codes can choose "windows Gdi output", i compile one source codes and the default is "Direct3D Output". thanks

No, I don't. But maybe the easiest way for you could be just delete all video_output plugins from your libvlc package except direct3d. Then you could be sure it will be used.
