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…

Stream your Windows desktop using ffmpeg

CLI, Codec, ffmpeg, free, MP4, Opensource, Transcoding, Video, VLC, Windows
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…

CineForm Direct-to-Disk Recorder

CineForm, Codec, HDTV, HDV
I have to admit CineForm is one of my favourite companies out there. I've visited them once and they are the nicest bunch of engineers you'll find on that side of the rockies :-). Aside from their famed CineForm Codec (which btw is awesome), they have just released the specs and conceptual drawings for what will probably be the coolest gadget at next years NAB ;-).They anticipate developing multiple members in the recorder product family - each targeting different recording needs. This first device targets HDV camcorder users and offers the ability to bypass the highly-compressed MPEG format. The features specification is below. They also imagine a sister device that would support single-link and dual-link HD-SDI recording.
