VLC Blackmagic Decklink

[jmggs]

Hi!

There is any chance to use decklink output (SDI, HDMI, Analogue Video) with VLC?
I think this is a must have feature for so good player.
There is any development on this?

Thanks

[Jean-Baptiste Kempf]

There is a version under development, but never merged.

[jmggs]

Great news!

There is any information about it? Any webpage or something?
Will be for Windows?

[Jean-Baptiste Kempf]

Linux, I guess, for a start.

[heiko]

Do I understand correct ?
With 2.1. we will find the outputs of Blackmagic Decklink cards available ?
Is this true also for Win 7 ?

Regards

Heiko

[Jean-Baptiste Kempf]

On linux, yes.

[heiko]

When can I do it in Windows 7 ?

[Jean-Baptiste Kempf]

You cannot directly.

[heiko]

Is there "any how to do" with ubuntu available ?

Windows version done: https://trac.videolan.org/vlc/ticket/12678. Testing appreciated!

I'd love to test and really need this functionality. We want to pick up a videostream with VLC and play it through the Decklink card. Have a Decklink Duo, VLC 2.1.5 and run W7 Ultimate 64. However... I'm not a developer. What do I need to do with the files? Just copy them in the VLC folder?

[ywlke]

Put the first dll file in the plugins/video_output folder in the VLC installation directory.

[richard.vanderveen]

I've copied the 'libdecklinkoutput_plugin.dll' to C:\Program Files\VideoLAN\VLC\plugins\video_output (I'm running the 64bit version of VLC), rebooted and started VLC player.
Then I navigated to Extra>Settings>Video and tried to select the Blacklink Duo in the pulldown menu 'Output'.

But it's not mentioned in the list? What am I doing wrong?

[ywlke]

Oh, it probably only works with the 32-bit version of VLC (which works fine on 64-bit Windows).

[richard.vanderveen]

Uninstalled the 64bit VLC, installed 32bit version, copied 'libdecklinkoutput_plugin.dll' to C:\Program Files (x86)\VideoLAN\VLC\plugins\video_output. Rebooted.
Still no possibility to select Decklink. Do I select the card at pulldown 'Output' or at pulldown 'DirectX'? Neither offer something called Decklink or Blackmagic...

It is also not mentioned in the list of plugins?

[ywlke]

There may be a better way to do this, but it looks like the plugins cache needs to be regenerated. You can re-run the vlc-2.1.5 installer after you've copied the plugin in place, and it should regenerate plugins.dat, after which the plugin should show up in the Output dropdown.

[richard.vanderveen]

Done it. But nope...
Checked plugins.dat in Worpad, libdecklinkoutput_plugin.dll is not mentioned?

Hi ywlke,

thank you for this great news about Decklink output support for windows. I use Decklink cards with VLC in linux without any problems.

Unfortunately, I have the same problem as richard.vanderveen reported. I don't see Decklink in the output module pulldown. I tried to reinstall VLC 2.1.5, deleted plugins.dat. The installer recreated plugins.dat but decklink module is not mentioned there.

[ywlke]

Well...alright, this unofficial build should work: https://www.dropbox.com/s/44iiwxpc1ys93 ... k.zip?dl=0
I do not provide any support for this build and it is provided for testing purposes only. The link is subject to be removed at any time.

[TobiWan]

I've tried your build. Unfortunately no video plays if the decklink output is active...

[richard.vanderveen]

Does Ubuntu with VLC work out-of-the-box?

[ywlke]

@TobiWan: did you also set audio to DeckLink? (The VLC plugin requires this...I don't know why.) What does your messages log show on debug?
@richard.vanderveen: No clue. I don't currently have a DeckLink to test with on anything.

[TobiWan]

Thanks, setting the audio output also to decklink works. The audio has interruptions, but fortunately I don't need the audio on SDI. If I want to play another video it does not work and holds the last frame of the previous one. After a restart of VLC it works again. Same if I stop and press play again.
