libvlc_media_add_option help

[10robinho]

Hi,

I'm confused with libvlc_media_add_option. This is documentation:

Add an option to the media.
This option will be used to determine how the media_player will read the media. This allows to use VLC's advanced reading/streaming options on a per-media basis.
The options are detailed in vlc --long-help, for instance "--sout-all"

If I add

Code: Select all

libvlc_media_add_option(media, "--ffmpeg-hw")

it won't work, but if I add

Code: Select all

libvlc_media_add_option(media, "ffmpeg-hw")

it works.

But, when I try to add

Code: Select all

libvlc_media_add_option(media, "aspect-ratio=16:9")

it is not working, and also with "--" in front won't work.

I know that this must be simple, what am I missing?

I don't know why it doesn't work, but you can use 'libvlc_video_set_aspect_ratio' :

Thankss, thatt worked, but still I'm unable to set some other options like

Code: Select all

libvlc_media_add_option(m, "no-video-title-show")

or

Code: Select all

libvlc_media_add_option(m, "--no-video-title-show")

... nothing is working. Just

Code: Select all

libvlc_media_add_option(m, "ffmpeg-hw")

is working... I'm confused as this must be something stupid I don't see...

btw. this is working

Code: Select all

cvlc --no-video-title-show ...some media...

1/ Add maximum static arguments when you create the media player with the prefix "--"
2/ Use AddOption with the prefix ":" for dynamic options than they don't have a libvlc method
3/ Use libvlc methods when they exist (Volume, Contrast, Hue, Saturation, Gamma, Subtitle, Aspect ratio, Rate, CropGeometry, Deinterlacemode, Audio track, etc....)
4/ READ THE DOC http://www.videolan.org/developers/vlc/ ... ibvlc.html http://wiki.videolan.org/Developers_Corner

Thank you, but I haven't made it work.

This is my code, what is wrong here? I'm using git build 1.2

Code: Select all

void play(char* addr) { m = libvlc_media_new_path(inst, addr); libvlc_media_add_option(m, "--no-video-title-show"); libvlc_media_player_set_media(mp, m); libvlc_media_release(m); libvlc_video_set_aspect_ratio(mp, "16:9"); libvlc_video_set_deinterlace(mp, "yadif"); libvlc_media_player_set_xwindow(mp, GDK_WINDOW_XID(gtk_widget_get_window(b_window))); libvlc_media_player_play(mp); }

and this is not working;

Code: Select all

libvlc_media_add_option(m, "--no-video-title-show");

Code: Select all

libvlc_media_add_option(m, "no-video-title-show");

Code: Select all

libvlc_media_add_option(m, ":no-video-title-show");

is there someting else?

Are you sure that is an input item option? Does it even work that way in the player?

[rvs75]

What are the arguments you use for libvlc_new ?

"--no-video-title-show" must be use in this arguments (first paragraph from my previous post).
