VLC Blackmagic Decklink

[richard.vanderveen]

Yes, same experience here. For me audio dropouts would be a real dealbreaker. Haven't tested audio yet though.

If video is played in a loop it keeps playing, so no fteezing last frame. I tested a udp video stream and that seemed to work fine. But like I mentioned before, no audio tested yet

[ywlke]

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 suspect though. Also, does anyone on the forum know why audio output is required? The API doesn't seem to require it.

I have a DeckLink card coming and can work on testing and stuff more directly soon.

[TobiWan]

It seems like the audio interrupts in a regular interval indeed. No errors pops up. Is there an advanced log console?

[ywlke]

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 version (https://github.com/videolan/vlc/blob/ma ... k.cpp#L668). I'm also hopeful I can find a way to not require the audio to be embedded in the DeckLink output.

[TobiWan]

Here is a log I have recorded while playing a mp4 file.

http://pastebin.com/h46xw6me

[ywlke]

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?

[TobiWan]

Sorry cannot upload this one. But I have the problem with almost any video file I have.

I'm running the desktop video driver package included in ATEM Software 6.1.

The audio plays about a second and is silent for a second or so afterwards. And plays again for a second. I think every one the log says that it has written audio samples it plays. I thought if VLC plays the file properly over my screen it should do so over decklink.

[ywlke]

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 to the plugin), but I didn't have the same audio issues you reported. Give it a try: https://www.dropbox.com/s/zqc985eimznra ... 1.zip?dl=0.

I don't know what is included with ATEM Software 6.1, but I'm currently using Desktop Video 10.2.2. I've seen reports that Desktop Video 9.x drivers are stabler in general, but I haven't had much luck with any of those versions detecting the outputs correctly from SDK-based code (both the code samples and the VLC plugin). I know the following combinations don't work with output for SDK-based code, and give error 0x80004002 (no outputs found):
Desktop Video 9.7.3 and DeckLink SDI
Desktop Video 9.8 and DeckLink Mini Monitor
Desktop Video 9.9.6 and DeckLink Mini Monitor

Just a note for anyone that has yet to try this, the HDMI output on the DeckLink Mini Monitor seems limited to YUV format, and not all monitors will display YUV (especially if you are using a HDMI/DVI cable), so you may need an actual TV to test with.

[TobiWan]

Thanks.
I'm still getting audio dropouts (same as before). I use the Decklink SDI. Is there anybody else who can give it a try?

[ywlke]

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 try: https://www.dropbox.com/s/apgieodjlose8 ... 2.zip?dl=0. I have no idea if the audio will be synchronized though.

[ywlke]

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.

[ywlke]

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

[carmeloconny]

Hello everyone. I have the same problem heiko.
I would like to try https://trac.videolan.org/vlc/ticket/12678
My OS is win7 32-bit VLC 2.1.5 my card is BlackMagic Intensity Pro.
I copied the files:
libdecklinkoutput_plugin.dll
decklink_windows.patch
libdecklink_plugin.dll

decklink_windows_headers.patch
decklink_helptext.patch

in C:\Program Files\VideoLAN\VLC\plugins\video_output

next run in C:\Program Files\VideoLAN\VLC

1:
vlc decklink_windows_headers -p1 decklink_windows_headers.patch /C:\Program Files\VideoLAN\VLC\plugins\video_output\decklink_windows_headers.patch

and
2:
vlc decklink_helptext -p1 decklink_helptext.patch /C:\Program Files\VideoLAN\VLC\plugins\video_output\decklink_helptext.patch

my problem is:
1) In VLC does not know how to use video output card.
2) I want to use this in DeckLink prompt run VLC.

You can help me? thanks
sorry for my english

[ywlke]

Please read the thread.

[carmeloconny]

thanks ywlke.
I try VLC 2.2.0 RC2
Use filter clone
directdraw: decklinkoutput
I see in my video windows desktopo, I see no external monitor connected to the black magic Intensity Pro.

[ywlke]

Need logs.

[carmeloconny]

thanks ywlke.
attach log debugging VLC.
I do not know if this file is correct.

if this is wrong, please tell me how to do the log file.

[ywlke]

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'

[carmeloconny]

thanks ywlke.
I have tried to change:
Videos- output modules- DeckLink output -
output card in 0; 1; 2; 3; etc No results useful.

other question: I have to activate BlackMagic card from the control panel windows.
VLC module DeckLink card is not active.

[carmeloconny]

for ywlke
log file Use decklink directly

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.

[carmeloconny]

thanks it works now! no audio sound

I'm having trouble finding the DeckLink output option.

I am running Ubuntu 14.10 and have VLC media player 2.2.0-pre2 Weatherwax (revision 2.2.0-pre1-15-g5178b24).
I have an HP Z420 with multiple BlackMagic cards installed (DeckLink SDI and Intensity Pro) and running DesktopVideo_10.3.4.
From VLC Preferences, if I go to Video and then Output, should I see DeckLink in the drop-down list? Or do I need to install a plug-in/extension to get this functionality?

[MarcusWolschon]

Is there a libdecklinkoutput_plugin for MacOS already or is it still Windows+Linux only?
I tried 2.2.0-RC2 and the latest daily and can't find the plugin in the list of video output plugins to choose from.

[Jean-Baptiste Kempf]

No, it's not built.
