[SOLVED] VLC + BlackMagic Intensity Pro on Ubuntu

[fab_beabloo]

Hi,

I'm trying to set up VLC 2.0.1 to stream video from Blackmagic Intensity Pro using one of its HDMI ports (running under Ubuntu 11.10).
I red all the blackmagic/decklink threads but, I was not able to get it worked.
Maybe someone can help me...

What I've done :
1.- Installed last drivers form Blackmagic

Code: Select all

dpkg -l | grep -i blackmagic ii desktopvideo 9.2 Blackmagic Design Desktop Video 9.2 - Driver and Utilities ii mediaexpress 3.1 Blackmagic Design Media Express

2.- Loaded module into Kernel

Code: Select all

lsmod | grep -i black blackmagic 443840 0

3.- PCI Card is recognized and using Kernel module

Code: Select all

01:00.0 Multimedia video controller: Blackmagic Design Device a117 Subsystem: Blackmagic Design Device a117 Flags: bus master, fast devsel, latency 0, IRQ 16 Memory at fe500000 (32-bit, non-prefetchable) [size=1M] Memory at fe400000 (64-bit, non-prefetchable) [size=1M] Capabilities: <access denied> Kernel driver in use: blackmagic_driver Kernel modules: blackmagic

4.- I changed grub configuration in order to get device created

Code: Select all

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash vmalloc=256M"

Code: Select all

ls -l /dev/blackmagic/card0 lrwxrwxrwx 1 root root 14 2012-04-25 11:25 /dev/blackmagic/card0 -> ../blackmagic0

5.- Compiled Source code of VLC with decklink-sdk (Blackmagic_DeckLink_SDK_9.5.zip)

Code: Select all

./configure '--enable-xvideo' '--enable-sdl' '--enable-avcodec' '--enable-avformat' '--enable-swscale' '--enable-mad' '--enable-a52' '--enable-libmpeg2' '--enable-dvdnav' '--enable-faad' '--enable-vorbis' '--enable-ogg' '--enable-theora' '--enable-mkv' '--enable-flac' '--enable-caca' '--enable-alsa' '--enable-qt4' '--enable-ncurses' '--enable-realrtsp' '--enable-twolame' '--enable-real' '--enable-x264' '--with-decklink-sdk=/usr/local/src/blackmagic_9.5/Linux'

6.- If I list VLC modules in search of decklink I got:

Code: Select all

vlc --list-verbose | grep decklink decklink Blackmagic DeckLink SDI input

But when I execute :

Code: Select all

vlc -vvv decklink://

I get :

Code: Select all

[0x9ad18c0] decklink demux error: Card has no inputs

[fab_beabloo]

Yes I saw that, but this is strange because there is a source connected to it... so... should have input, no ?

[Jean-Baptiste Kempf]

Maybe. But the code seems to say that QueryInterface( IID_IDeckLinkInput, (void**)&p_sys->p_input) fails

[fab_beabloo]

So what can I do ? Where could be the problem ?

Thanks for your support.

[fab_beabloo]

Hi,

Solved my problem using exactly same version for Drivers and decklink-sdk, latest for both.

Thanks.

[fab_beabloo]

Hi,

Under /usr/local/src/blackmagic_9.5/Linux, I just have 2 directories : include & Samples. And only include directory is needed for compilation.
In order to debug VLC compilation, have a look to the config.log file generated during configure process.

Hope that helps.

[fab_beabloo]

I think the first thing to check is that the card itself is accepting the video you are giving it. The format which the card expects is very important. So, I recommend you to run the MediaExpress application (its part of the driver download tarball) to check whether the card is successfully capturing the camera (set the correct Project Video Format in Media Express' Edit->Preferences menu).

Its not worth the effort to try VLC with a Blackmagic card until you've confirmed that you can see incoming video with Media Express. If you continue without first confirming that, you'll never be sure whether any problem you have is due to VLC, the Blackmagic card or the camera (or any other device you plugged).

When you know the mode used by your input device, you just need to inform VLC about the one to use which must be one of these:

Code: Select all

If you're ready to try VLC, it is most important match the VLC video format arguments to match the input's format.
As an example, the arguments for an interlaced HD camera with 50Hz refresh rate (1080i50) using the HDMI input to the capture card are:

Code: Select all

vlc -vvv decklink:// --decklink-video-connection="hdmi" --decklink-mode="Hi50" --rtsp-timeout 0

You'll have to change these to match your own camera/device.

Example : if your input device displays using FullHD at 24Hz you need to use 24ps mode, any other mode will work.

Hope that helps.

[fab_beabloo]

Good to know !

So with a command line similar to this one, that should work :

Code: Select all

vlc -vvv decklink:// --decklink-video-connection="hdmi" --decklink-mode="Hp25" --rtsp-timeout 0

Hi, I have some problems when I configure decklink. Terminal said that:
"bash: ./configure: No such file or directory"
Oh, please help me!!!

[nkoriyama]

If you get source from git, you have to do "bootstrap".

Also have a look UnixCompile

[rst5018]

Thanks very much!!! But I haven't understood yet. I want to run vlc to capture camera with blackmagic intensity pro card. But now I can't. Please show me the way to do that!!!
Thanks!!!

[rst5018]

Hi, I've compiled vlc with decklink.

Just read the logs.

[fab_beabloo]

Your compilation must not be correct. Check that !

[rst5018]

I've been compiled again. And when i run vlc with decklink:

vlc only show one image. It's not video. Please help me!!!
