Enabling WASAPI

[Hanley]

How do I enable WASAPI? I used libvlc_audio_output_list_get to see all the available audio outputs and it showed:

waveout
aout_file
aout_directx
amem
adummy

I'm using vlc 2.1 on Windows 8

If you mean to use WASAPI through Windows' Multimedia Device API and your VLC build includes it, the plugin name is mmdevice.

Thnx.

Sorry if I re-open this topic but I wonder how in VLC 2.0.8 64-bit with Windows 8, I can use WASABI as AUDIO OUTPUT.

I use it with Foobar2000 and I'd like to use it in VLC too.

[Rémi Denis-Courmont]

You can't. Only VLC 2.1.0 and later support WASAPI.

[pipppero]

You can't. Only VLC 2.1.0 and later support WASAPI.

I really don't understand...

1) where I can get 2.1.0 and later version of VLC?

2) why to me the last is 2.0.8?

3) exist a 64bit version of 2.1.0 version?

I really need wasapi on my vlc because I watch to concerts movies mostly.

1) videolan.org
2) see above
3) yes

Sorry, but I really haven't understood the discussion above.

I'm running VLC 2.1.0 (Rincewind) under Windows 7 with a 7.1 channel HDMI output to an AVR.
What are the steps that I need to take to enable WASAPI in exclusive mode?

I would like stereo soundtracks to be sent to the receiver as 2.0 HDMI channels so that the receiver can process them with Dolby ProLogic or DTS Neo. Currently, VLC is playing stereo sound tracks in just the left and right front channels of the 7.1 HDMI output, with the other channels silent, which prevent the use of ProLogic or Neo. Presumably this is because VLC is using DirectSound instead of WASAPI exclusive.

Thanks for whatever help you can provide.

[Rémi Denis-Courmont]

Exclusive mode is not implemented in the current WASAPI plugin, nor is codec pass-through as of VLC 2.1.x. For pass-through, you need to stick to DirectSound or WaveOut for now.

Correct me if I'm wrong, but as I see it, at the current implementation state of the WASAPI integration, the VLC media player is useless for real BluRay playback. Any container file with a FLAC/DTS-HD MA/TrueHD audio track is not correctly transmitted through HDMI to a compatible HDCP A/V receiver and the receiver gets 2CH instead of 6/8CH lossless?

[Jean-Baptiste Kempf]

This is unrelated to WASAPI.

Great that really helped! One last question. Should I ignore the "no audio output modules matched" error?

It seemed to fix the audio issues I was having anyways...

You need to init COM before.
