Please take a look at the other thread here: https://forum.videolan.org/viewtopic.php?f=7&t=107805

Oh, you either need to also set audio to decklink, or in the VLC advanced settings for the decklink plugin, uncheck the option to wait for audio.

Yes, that's correct. Use decklink directly, your clone filter isn't working:
core error: Failed to create video filter2 'clone'
core error: Failed to add filter 'clone'

Need logs.

Please read the thread.

Yes, the latency was due to not embedding the audio. Added low latency support (by way of the BMD configuration flag) and using blocking playback instead of scheduled. Check advanced options to enable. Currently untested. https://www.dropbox.com/s/mddj7ut1q0yn0 ... 4.zip?dl=0

An updated link with fixed support for scaling videos. https://www.dropbox.com/s/x5u4ny3fl3l2n ... 3.zip?dl=0

In preliminary testing, audio seems to arrive early but I'm not certain that that wasn't due to the source video itself.

Actually...this info isn't in the debug output, but what video mode did you use? Try a video mode that is not 50-60 fps. I have a feeling VLC has trouble keeping up with high fps. I also just built a currently untested version that allows you to use non-Decklink audio output, so you can give that a ...

The DeckLink code from 2.1 doesn't work with my output-only DeckLink Mini Monitor card, so I recompiled based on the 2.2 codebase which already has that fix. I encountered what seemed to be some hardware-specific issues with flickering/loss-of-sync? on the HDMI output (fairly certain it is unrelated...

Hmm not sure what to make of that. Does the video play properly with the Blackmagic software? Maybe try using a different driver version (Blackmagic Desktop Video package). What version do you currently have?

How often is the audio dropping? Can you upload the file somewhere?

Yeah, you can go to Tools -> Messages and then change Verbosity from 0 (errors) to 2 (debug). Do you notice if the audio becomes unsynchronized with the video either right before or after it interrupts? The code suggests that's why it does it but it's one of those things that was in the Linux versio...

Awesome! Did you notice any debug/error messages when the audio dropped? Or if it drops on a regular interval? Any Linux users have the same issues? I don't see why these would be Windows-port specific since I didn't really change any of code that does the work. There were some lines that looked sus...

@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.

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.

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.

Copy 'libdecklinkoutput_plugin.dll' to C:\Program Files (x86)\VideoLAN\VLC\plugins\video_output; it only works with 32-bit VLC.

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

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

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

Okay, I did something wrong in the compile process. If anyone wants to test the modules that would be awesome. See https://trac.videolan.org/vlc/ticket/12678 for both the video_output and access modules' DLLs and the source patch.

I was able to successfully compile the Decklink access and video_output modules for Windows with the rest of the VLC 2.1 tree, but the modules do not show up in the VLC "Plugins and extensions" listing. Where might I start troubleshooting why VLC does not see the modules? I would expect to...

Any update?
