So over christmas holidays I spent about 5 days to perfect my raspberry pi based internet radio player. You’ll need the following hardware: Raspberry Pi model B USB Wifi dongle (something that works with Raspbian would be nice). I got this one (http://www.adafruit.com/products/1030) from Adafruit. SD card (I’m using a 16GB card, but I think 8GB should be good to start with) Bluetooth 4.0 dongle. I’m using this one from ASUS (http://www.asus.com/ca-en/Networking/USBBT400/) that seems to work fine in Linux/Raspbian PiTFT resistive touch screen assembled from Adafruit (http://www.adafruit.com/products/1601) Pack of 20 tactile buttons from Adafruit (http://www.adafruit.com/products/1489) for the above screen (You need to solder these in…..very simple) Appropriate power USB power supply. Again I’m using the one from Adafruit (http://www.adafruit.com/products/501) Standard A to micro-B USB cable (http://www.adafruit.com/products/592) (optional) PiTFT Enclosure from…

I've finally got this project to a point were I can do a write up on it. The following hardware is needed: Raspberry Pi 512K version (or BeagleBone Black) Logitech C920 Webcam 16 GB micro SDHC card (can probably do it on 8GB too) Wireless dongle supported by linux (I'm using a TrendNet TEW-645UB which was pretty much plug and play) The goal of this project is to get the following installed and configured: CRTMP streaming server C920 install and config (v4l2), ffmpeg installation, boneCV installation from Derek Molloy's site configuring ddclient for dynamic DNS (optional) putting it all together and creating a webpage with embedded JWplayer to view the stream UPDATE: Sound works now on BeagleBone Black. On Raspberry you will run into alsa buffer xruns. See below for…
I've already covered how to do this with vlc a while back in parts 1 followed by part 2. I just found out that something very similar in results can be done with ffmpeg. ffmpeg has recently added support for directshow filters which now allows one to capture the screen and stream and/or save it. Here is how you can do this: 1.) Grab a copy of the Screen Capture DirectShow source filter from Unreal Streaming Technologies. It's about half way down that page. They have both the UScreenCapture X86 Edition and the X64 Edition (depending on your OS installation). I used the 64 bit filter on a Windows 7 64 bit installation. 2.) Install the filter and make sure you make the following changes to your windows registry using regedit. The default frame…
The answer to that is maybe, we'll see. But all that aside if you're interested in a minimalistic video player that can handle more codecs than VLC and is generally faster then give Movist a try.The unique thing about the player is that it allows you to switch codec engines between ffmpeg and quicktime based on file extensions. Oh and did I say it's FREE aswell :-).
For those of you who don't know OpenShot Video Editor(TM) is an open-source program that creates, modifies, and edits video files. OpenShot provides extensive editing and compositing features, and has been designed as a practical tool for working with high-definition video including HDV and AVCHD.Jonathan Thomas and crew have reached their 1.0 milestone (congrats :-)). The program is rock solid and is running beautifully on my Ubuntu 9.10 installation.OpenShot's Features include:Support for many video, audio, and image formats (based on FFmpeg)Gnome integration (drag and drop support)Multiple tracksClip resizing, trimming, snapping, and cuttingVideo transitions with real-time previewsCompositing, image overlays, watermarksTitle templates, title creationSVG friendly, to create and include titles and creditsScrolling motion picture creditsSolid color clips (including alpha compositing)Support for Rotoscoping / Image sequencesDrag and drop timelineFrame stepping, key-mappings: J,K, and…
There are a lot of fantastic free software packages out there for the PC if you're running windows. VLC, Firefox come to mind. The problem is that it takes a long time to install all of them on your PC. You know the routine, click, wait for download, double click, next, next, next, etc......Well, why? Head over to Ninite's website, choose the applications you want and let them create a custom "Meta Installer" for all the applications in one package. Run the installer and wham, you got all those free/opensource apps downloaded and installed on your machine in one shot, with minimal clickage :-). No sign-up required, Free for personal use, Just in time for Windows 7 Upgrade (or potentially downgrade). Now if only someone would make something like this…
Title says it all.....head over to TechPosters (kinda slow right now) and snag your favourite cheat sheet/reference card. There are also more of this kinda stuff over at Cheat-Sheets.org as well.
Yep, those crazy open source hackers over at dvinfo.net have done it again. You thought the RED camera brought about a revolution in dcinema, well, you ain't seen nothing yet. Apertus is using the Elphel 353, free software and open hardware camera. The Elphel Camera which this entire project is based on is basically an excellent security camera that can do some real magic. The camera uses an Aptina CMOS bayer-pattern sensor with an optical format of 1/2.5" (5.70mm x 4.28mm) and a native resolution of 2592x1944 (5 Megapixels). It features a 12 bit ADC and supports: region of interest, on-chip binning and decimation. Aptina claims that the chip has 70db of dynamic range at full resolution and 76db when using 2x2 binning. The camera has a standard C-mount but…
So after yesterdays rant, I went back and figured out how to install the Cacti monitoring software (OSS, Free) onto a Ubuntu 9.04 "Jaunty Jackalope" Desktop installation. This guide uses packages only, no compiling, no Makefiles or anything like that.....You should be able to just follow this and get a fully functioning Cacti installation in about 30 minutes. Here are the steps:install ubuntu 9.04 ("Jaunty Jackalope") Desktop Edition on your machine Login, open a Shell window and install ubuntu LAMP (Linux/Apache/MySQL/PHP) server stack on your machine "sudo tasksel install lamp-server". Note: Make sure you remember the password for "root" user in mysql Database, write it down somewhere, we will need it later on.Get a superuser shell started since it will make for less typing. "sudo -i" followed by your password.…
The USB-powered Beagle Board is a low-cost, fan-less single board computer utilizing Texas Instruments’ OMAP3530 application processor that unleashes laptop-like performance and expansion without the bulk, expense, or noise of typical desktop machines.Beagle Board is based on an OMAP3530 application processor featuring an ARM® Cortex™-A8 running at up to 600MHz and delivering over 1,200 Dhrystone MIPS of performance via superscalar operation with highly accurate branch prediction and 256KB of L2 cache. Focal to Beagle Board experience is the high-speed USB 2.0 on-the-go (OTG) port that can be utilized to provide power to the board or to deliver highly flexible expansion. Standard PC peripherals can be connected to Beagle Board using the USB with a mini-A to standard-A cable adapter, DVI-D using an HDMI to DVI-D adapter, or through the MMC/SD/SDIO…
