Hi friends,

I have mainboard ASUS AT3IONT-I. While I play full HD movie (from hard disk or from RTP stream) via VLC player, movie plays without problem. CPU consumes up to 10%.
But when I try to play the same stream in my WPF application (with --ffmpeg-hw ), audio plays without problem, but video freezes. Log contains a lot of following messages:

main warning: picture is too late to be displayed (missing 213 ms)
main debug: picture might be displayed late (missing 7 ms)

In this case, CPU consumes cca 40%

My WPF player control uses WindowsFormsHost control with WinForm Panel. I tried also WinForm application and VLC embeded in HTML with the same result.

Do you have som hints, how to solve this issue?

Thanks
Peter

Are you sure there is no chroma conversion?

I instantiate libvlc instance without arguments, so I expect defalut setting will be used.
This is short excerpt from my code:

// create vlc instance
IntPtr _vlcInstance = LibVlcMethods.libvlc_new(0, null);
// create media
IntPtr media = LibVlcMethods.libvlc_media_new_path(_vlcInstance, Encoding.UTF8.GetBytes(path));
// create player from media
IntPtr _vlcPlayer = LibVlcMethods.libvlc_media_player_new_from_media(media);
// set window handle
LibVlcMethods.libvlc_media_player_set_hwnd(this._vlcPlayer, this._hwnd);
// release media
LibVlcMethods.libvlc_media_release(media);
// play media
LibVlcMethods.libvlc_media_player_play(this._vlcPlayer);
...

Thanks,
Peter

I don't know the wrapper you use, but, it should be a function like "LibVlcMethods.libvlc_media_add_option".
Probable use in your code : libvlc_media_add_option(media ,"-ffmpeg-hw") or libvlc_media_add_option(media ,Encoding.UTF8.GetBytes("-ffmpeg-hw"))

Thank you rvs75,

your hint, together with new build, solved my problem.

Thanks again,
Peter

hmm.... Now all HD videos are ok, but when I tried to play non HD from RTP stream, video output is fragmented.
