Looking to pay an expert for help with small project.

Hi There,

I'm very new to this. I've been asked by a client to create several RTSP streams for a small IPTV project.

After reading many forums, it looks like the best method is using the BlackMagic Intensity Pro Pci-E card in a Linux box with VLC to create an RTSP stream.

Can anyone help me with this project? I'm prepared to pay for your time. I will also be looking for ongoing support for this system.

Cheers,
Matt.

You might use Libbmd or bmdtools to capture and avconv to feed any rtsp-compatible server.

I thought you can use vlc to encode + stream?

Anyway, I'm half way there.... I have Ubuntu Desktop 12.04 set up using Intensity Pro PCI-E card.

I'm using an HDMI splitter to remove HDCP from my sat top box.

I've matched the card and my HDMI output (from this forum this is where a lot of people get stuck) and blackmagic media express is showing perfect video.

Tomorrow I'll be compiling VLC with decklink-sdk and then playing around with vlc to create stream from capture card.

I'll also check out your method. Many thanks.

Hi,
I have done this with the Decklink duo on Ubuntu 12.04 LTS, I guess that it will work as well with the Intensity.

I°) Install desktop video and media express (you can dowload it on the blackmagic website), and then load the driver :

// Desktop Video :
dpkg -i desktopvideo-9.7.3-amd64.deb
apt-get -f install
dpkg -i desktopvideo-9.7.3-amd64.deb

// Media Express :
dpkg -i mediaexpress-3.2-amd64.deb
apt-get -f install
dpkg -i mediaexpress-3.2-amd64.deb

// Load the driver :
modprobe blackmagic

II°) Download the blackmagic SDK (available on the blackmagick website) and compile your own VLC (download VLC's sources on the VideoLAN website) :

cd /path/to/your/vlc
mkdir build
cd build

apt-get build-dep vlc

../configure --enable-x11 --enable-xvideo --enable-sdl --enable-avcodec --enable-avformat --enable-swscale --enable-mad --enable-libdvbpsi --enable-a52 --enable-libmpeg2 --enable-dvdnav --enable-faad --enable-vorbis --enable-ogg --enable-theora --enable-ffmpeg --enable-faac --enable-mkv --enable-freetype --enable-fribidi --enable-speex --enable-flac --enable-live555 --with-live555-tree=/usr/lib/live --enable-caca --enable-skins --enable-skins2 --enable-alsa --enable-qt4 --enable-ncurses --with-decklink-sdk='/path/to/the/blackmagic_decklink_sdk/Linux'

make

III°) Add VLC to your path

IV°) Launch VLC with your card as input to test :

vlc decklink://
(depending on your camera type, you may need to add --decklink-mode="Hi50", where Hi50 is an exemple - see the doc for other modes)

V°) Stream RTSP (this command is an exemple, see VLC's doc to adapt it to your needs) :
vlc -vvv -I rc decklink:// --decklink-mode="Hi50" --rtsp-timeout=0 --no-sout-audio --sout "#transcode{width=480,vcodec=mp4v,fps=15,vb=56}:rtp{name=my_stream,dest=127.0.0.1,ttl=10,port=3002,port-video=3012,sdp=rtsp://ip_address:3002/stream.sdp}}"

TimIFR - thanks so much. I was about to follow this script I found:

Thanks for your help. I went through your steps, however when I tried to run VLC, I got this message. I definitely added it to the path:

The program 'vlc' is currently not installed. You can install it by typing:
apt-get install vlc-nox

Did I miss a step?

Regards,
Matt.

Thanks for the pointers everyone. I've been hacking away at this for hours and success!

I'm nearly there. Need to work on a few things but I'm able to stream from my sat top box via my server across the network to my PC running VLC.

Hi,
I have installed BlackMagic Intensity Pro Pci-E card in a Linux server with VLC to creI have used (((TimIFR))) config
But I can not get the stream it,s with error
main decoder error: no suitable decoder module for fourcc `UYVY '. VLC probably does not support this sound or video format.

What code are you using to launch VLC?

Hi Mattc
I use this code

vlc -vvv -I rc decklink:// --decklink-mode="Hi50" --rtsp-timeout=0 --decklink-video-connection=hdmi --sout "#transcode{width=480,vcodec=mp4v,fps=15,vb=56}:rtp{name=my_stream,dst=127.0.0.1,ttl=10,port=3002,port-video=3012,sdp=rtsp://109.xx.xx.2:3002/stream.sdp}}"

Hi
I have used this code for check card input
cvlc decklink:// --decklink-video-connection="hdmi" --decklink-mode="Hi50"

I have this result

Does the input play via Media Express?

I use ubuntu server without desktop

check vlc stats
