libvlc_vlm_set_output() doesn't work after play

[jlz]

Hello everyone

I try vlc-1.2.0-git-20100508-0002-win32-debug.zip nightly build and If I call to libvlc_vlm_set_output() after play but doesn't run. On the example code the event type VlmMediaChanged tell me that the "command" is executed but rtp stream output only run if libvlc_vlm_set_output() is executed before play.

Is this a bug or a feature?

Thanks in avance

Shouldn't libvlc_vlm_set_output() be called before playing?

[Rémi Denis-Courmont]

Yes. You can't change outputs dynamically.

[jlz]

OK, but :
- where is documented this feature?
- why libvlc_vlm_set_output() doesn't return error when is called on playing ?
- why this
libvlc_vlm_play_media ( ...)
libvlc_vlm_set_output(...)
libvlc_vlm_stop_media (...)
libvlc_vlm_play_media (...)

set the new output succesfully


thanks
