Ubuntu Multimedia :: Digital Signage Project For Burning Man Camp?
Aug 2, 2010
I'm working on a digital signage project for my burning man camp.My display needs to cycle, on a timer, among various pieces of content, including:
* images
* video
* flash content
* information screens (vanilla xhtml)
Ideally, it would also have a generic xml/rpc interface for easily updating information screens via iphone/android. I'm contemplating whipping something up in jquery to run in a fullscreen browser, but have a feeling I might be reinventing the wheel.

opensource or free digital signage software that supports videos. If it will support even media streaming will be better

A while back, I used boot camp to dual boot OSX and Ubuntu on my iMac. It was fine, worked well - but I eventually took the partition off because there was some software corruption in OSX. I reinstalled OS X and now I want to dual boot Ubuntu. I can't! I created the partition - like last time, in Boot Camp, and I installed Ubuntu - I made sure to keep Grub on the Ubuntu partition only. But when I go to reboot (you know, after it finishes installing) I press option/alt and the Ubuntu partition does not show, only the Mac partition. Why is this?
ed: One thing that I remember is that I formatted the Ubuntu partition ext4 - I don't recall whether or not I used ext3 before, and do not know if that makes a difference.

Does anyone try installing Linux on Boot Camp? I am about to dual boot Mac OS X 10.6.4 with openSUSE 11.3 in my MBP 13". However, I still don't have any idea whether it's going to work or not since Apple doesn't issue any support for dual booting Mac and Linux.

Today I want to install Ubuntu on a friends laptop. I finally convinced him to leave Windows and move on to Ubuntu. Ironically this has brought me into problems. I have downloaded the ubuntu-10.10-dvd-i386.iso and ubuntu-10.10-desktop-i386.iso to make a bootable cd/dvd to install Ubuntu. Now both K3b and Brasero give me problems burning one of the .iso files. I already waste some CDr and DVDr. I will share some logfiles for your info;

Yesterday I spent a good couple of hours putting together a video. When I shut down, Lives flushed my entire project because it uses a tmp working directory and places it as default in tmp.Today, I changed the working directory to Video, thinking this would be safe. Instead, the programme quit half-way through editing and I have now lost another good couple of hours.is there any way of saving my project?I can still see the .lay file but there doesn't seem to be any way of opening it.

Previously I could plug my EOS 20D into the USB and f-spot would pop up and let me import photos. This was on 9.10. The camera is fine, it still does exactly what it did on the machine next to me which is still running 9 (or 8, I forget).

Trying to burn with CD/DVD Creator. I can't find anything in the program (settings wise) that will automatically convert mp3 files to wav files. I used to use k3b, and it used to do that. I did try installing k3b, however I am getting glitches in the program. I don't want to covert mp3 files over to wav every time I want to burn a new cd. Does anyone have a suggestion as to another program or place to find the burn setting for encoding?

I keep getting the following error when trying to burn a DVD, and unfortunately am none the wiser as to what it means:
Code:
DBus error
This is using both Brasero and K3b, the disk stops writing about halfway through on Brasero and a tenth of the way through on K3b. I'm just trying to burn a data DVD and have tried low & high speeds.
Latest version of 64bit Ubuntu

I have finally ripped my dvd collection to my external hard drive, and now I want to make fair use back ups of my discs (incase the worst happens and I lose my HD and my original disc) I remember there was a tutorial on these forums a while back but I can't seem to find it.

I need something that will convert and then burn a DVD. I have tried almost all of the options on Ubuntu including Devede, K3B, Avidemux, Qauthor, Tovid, Transmageddon, DVDstyler and probably more. None will convert to a NTSC format without trying to create a DVD menu which seems to be the problem involved in playback except for Transmageddon, but it fails to provide the bup and ifo files to go with the video files to get K3B to burn it. I'm able to make DVD's that work on computers, but I want DVD's that will play in my DVD player. Any programs other than the ones I named that can do the conversion without creating a DVD menu and create all the files needed to get K3B to burn it? If needed, I'm converting from AVI. Also,

I have a "Digital Copy" of District 9 that came with my Blu-Ray disc. My problem is that the file is a DRM encoded .wmv so that I cannot play it back in totem on my 32-bit Karmic system. VLC plays it back as distorted noise.I know this BS is because of the files 'Digital Restrictions Management'. My Question is: What programs should be used to break DRM and re-encode the file, and HowTo?

I've trolled the forums for about 30 mins or so already looking this up, but can't seem to find any solutions. Most threads seem to end with either a "report to launchpad" or they just end without resolution. So in case I've missed a solved thread:
Plugging my Kodak C503 in gives inability to mount due to lock issues, the infamous -60 lockout. However, I get TWO icons in metacity, neither are mounted/will mount. Turning the cam off removes both, and I can't get down to only one. Not sure if this is because it's reading the camera's internal memory + my SD card.
So, I pulled the SD card out, and jacked it into my card reader in my lappy. no dice. In fact, none of my SD cards work; leading me to believe I need to find drivers for it.
Notes: (1)It's a Pavillion ZD7000 (2)nothing pops up in fdisk (3)I really don't want to load up windows

I've been searching for a while now and come up empty handed, but after some research on the history of digital camouflage and how it was created I was able to devise a simple method for creating at least a close approximation of the real thing.
Step 1: start with a picture of the "texture" you intend to use. it doesn't matter if it's a low resolution picture because you are going to intentionally pixelate it
Step 2: use the noise plugin "pick" and create some static in the picture. I've found that you can just set everything to maximum and apply the pick with good results.
Step 3: (optional) if you want this to be a repeating pattern, at this time apply the "make seamless" tool under Map plugins.
Step 4: Apply a pixel blur. dial it in just to where you start to see hard pixel edges forming. In most digital camo patterns, the pixels are taller than they are wide, about a 3:2 ratio
Step 5: Choose the number of colors you want in your camo pattern. Virtually all digital patterns are either three or four colors, but never any more than that. Change the image mode from RGB to 4 color indexed. Then you can change it back to RGB if you wish to change the colors in your camo.
you can play with the settings on each step to dial in something that looks proper. The proper scale for your camo is roughly 1/4" tall pixels. Try playing with different textures, or even non digital camo prints. In about two minutes we've just created both a woodland and a desert digital print that is close enough to pass for MARPAT using free software.

For no conceivable reason, pulseaudio will no longer output via the spdif connection on my onboard sound card.Up until now, various applications could output digitally (mostly using via the alsa plugin) fine. DVD playback would passthrough DD/dts bitstreams if the application was set to communicate with alsa directly. The sound profile in Ubuntu's audio applet would have to be set to Analog Stereo Output for this to work, no idea why.
Now, all the works is digital passthrough via alsa (i.e DVDs). So definitely not a hardware issue. Regular audio either via the alsa plugin or using pulse directly does not work so no music/system sounds/flash etc. All sliders are unmuted (see pics linked below) and the volume meters all show movement with sound activity. Changing the Profile setting does nothing, I thought maybe it had been fixed so digital actually meant digital.This has happened before (sometimes triggered by DVD playback and DD passthrough) but usually fiddling with the mute toggles fixed it.Possibly this has been caused by a recent update.

I'm using a terratec EWX 24 96 sound card with ubuntu studio, and I have sound with the digital output, I have no sound with the digital input.
I had sound with the same configuration in Windows XP, and all the hardware is ok.
I think I have no sound at all, with Ardour or Rosegarden, that's like if the digital input was not here in jack.

Does anybody use USB HDTV (digital or hybrid) tuner ?
1) does teletext work in digital TV ?
- Do teletext pages appear immediately after page numbers entering or
- must you wait every time because of counter rewinding ?
2) Does analog FM radio (88 - 108 MHz) work in that kind tuners ?

I have a Video DVD on HDD. Complete structure in VIDEO_TS folder. Problem is I can't find a program to successfully burn it. Brasero doesn't even have an option for Video DVD. The Video DVD option it has wants to try and do encoding or something. It doesn't even take the VIDEO_TS folder. If you choose data disc and burn the VIDEO_TS folder then the disc don't work in stand-alone DVD players and only works on the Linux pc itself.
Gnomebaker has the same problem as above.
K3B doesn't want to work. Just keeps giving the error "Unable to determine size of image".
So where to turn ? Is there an app for Ubuntu that can actually burn a video dvd to be playable in a stand-alone dvd player ?

I have added a couple of clips (1080p50 XVid) to a project, and each of them play fine in the Clip Monitor. I want to add these clips to the timeline and add the Dissolve transition between them.
I have achieved the above and when I click on the Play button on the Project Monitor, I can see the project playing including the transition. All fine so far.
After this first play of my new project, I have tried to move the playback position bar and once I do so, the project monitor goes black. From this point on, I cannot see my project playing whether I start playback from the beginning or from an arbitrary mid-point. I may see a flicker of an image, and the transition effect may appear but that is it until I quit Kdenlive and start again.
I'm stumped as to what could cause this. I did wonder if it was because I was using onboard graphics, but I have upgraded that element of the computer today with no change in the result.
Computer specifications are as follows:
* Ubuntu 10.04LTS Lucid Lynx
* Intel E3200 Dual Core Celeron 2.4GHz
* 1GB DDR2 800MHz RAM
* MSI NVidia 8400GS 512MB Graphics Card
I know the machine doesn't have the highest specification in the world, and perhaps more RAM is needed for this job. I don't believe this to be the causing factor in this problem though considering playback is initially achieved.
Following a search of the internet, I've attempted two possible ways of resolving this: disabling Compiz, starting Kdenlive from the terminal using 'env XLIB_SKIP_ARGB_VISUALS=1 kdenlive' and running the Config Wizard. Neither has given the resolution.

I have a GA-MA785GMT-UD2H with ALC889A audio. I hooked up the optical cable and now only get sound from amarok. I don't get any sound from firefox or vlc. I looked at other posts but all refer to ubuntu and pulseaudio. I want to be able to use the optical out for all audio i.e firefox(flash) and vlc.

My sound was working, but I got a new SPDIF cable, so I switched it to digital. It worked fine. But then I restarted and now it's gone.
aplay -l tells me I have no soundcard but lspci -v lists
00:14.2 Audio device: ATI Technologies Inc SBx00 Azalia (Intel HDA)
Subsystem: ASUSTeK Computer Inc. Device 836c
Flags: bus master, slow devsel, latency 64, IRQ 16
Memory at f9ff4000 (64-bit, non-prefetchable) [size=16K]
Capabilities: <access denied>
Kernel driver in use: HDA Intel
Kernel modules: snd-hda-intel
So my soundcard is there.

I can get 5.1 surround by using the plug:surround51 device.
Have gone though other guides trying to fix the problem but no luck. how to get the digital stuff working. I have included some outputs.

Here is the update to the old thread that somehow disappeared "HOWTO: A52 Encoded 5.1 Surround Sound Awesomeness with PulseAudio and ALSA on Hardy" thread (archived here). See also this bug report.There are two steps here: add the a52 plugin, and tell pulseaudio to use it.
Step 1:
Go to a terminal and do the following:
Code:
sudo bash
echo "pcm.a52 {[code]....
Pulse should come back on its own unless you disabled autospawn.Now pulse should be aware of your digital surround output. Go to System -> Preferences -> Sound. Click on the "Hardware" tab and change the profile to one of the 'Digital Surround 5.1' profiles. Play some sound (I like to test with www.pandora.com) and enjoy!If it doesn't show up, it probably means that alsa didn't create it correctly. To test if alsa sees the a52 device, type:
Code:
aplay -D a52:0
If it errors out (audio open error: No such file or directory) then that means it did not like your asound.conf settings. You might learn something by looking at the output of 'sudo alsa reload' or just 'aplay'.[code].....
