ActiveX: show only audio spectrum with a A/V source

[michel_etica]

Hi,
I have an rtsp audio+video source, and I would like to visualize the audio spectrum ignoring the video.
I've tried (in C#) different combinations of options, such as:

Code: Select all

string[] options = { ":audio-visual=visual", ":show-display=true", ":no-video-title-show", ":no-video", ":effect-list=spectrum" }; vlc.playlist.add("rtsp://whatever", "OnlyAudioSpectrum", options); vlc.playlist.play();

or:

Code: Select all

string[] options = { ":audio-visual=spectrum", ":show-display=true", ":no-video" }; vlc.playlist.add("rtsp://whatever", "OnlyAudioSpectrum", options); vlc.playlist.play();

Actually I've tried also more options combinations, but nothing shows up what I would see using the VLC player's option: Audio -> Show -> Spectrum (on my italian installations is Audio -> Visualizzazioni -> Spettro).

Any hint?
Thanks,
Michel

The command line (for VLC 1.0.5 under windows) to achieve the behaviour I'd like on the ActiveX is:

Code: Select all

vlc --no-video --audio-visual=visual --effect-list=spectrum rtsp://my_stream

Sadly, the same options passed to the ActiveX result in a black component content.
