So over christmas holidays I spent about 5 days to perfect my raspberry pi based internet radio player.Screen Shot 2015-01-21 at 9.05.44 AM Screen Shot 2015-01-21 at 9.06.13 AM

You’ll need the following hardware:

  1. Raspberry Pi model B
  2. USB Wifi dongle (something that works with Raspbian would be nice). I got this one (http://www.adafruit.com/products/1030) from Adafruit.
  3. SD card (I’m using a 16GB card, but I think 8GB should be good to start with)
  4. 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
  5. PiTFT resistive touch screen assembled from Adafruit (http://www.adafruit.com/products/1601)
  6. 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)
  7. Appropriate power USB power supply. Again I’m using the one from Adafruit (http://www.adafruit.com/products/501)
  8. Standard A to micro-B USB cable (http://www.adafruit.com/products/592)
  9. (optional) PiTFT Enclosure from Adafruit (http://www.adafruit.com/products/1892).

DEKTEC: DekTec introduced the DTA-2180 low profile PCIe H.264 encoder. The DTA-2180 is a low latency — 150 to 600 ms — H.264 hardware encoder based on the Magnum chipset. It supports MPEG-2 and H.264 and up to 16 channels of audio. Audio can be encoded as AC-3, AAC or MPEG-1 Layer 2. The DTA-2180 offers a 10 bit 4:2:2 option for contribution encoding.The DTA-2180 has a 3G –SDI and HDMI input and an ASI output. The compressed stream output — TS encapsulated H.264 or mpeg-2 — is also available on the PCIe for real time streaming, processing and recording.1

NIMBUS: The WiMi6400T and WiMi6400R provides high quality Full HD encoding/decoding function with low latency of 40ms for encoding and decoding, each.Read the rest

Stream your Windows desktop using ffmpeg

datePosted on 10:26, November 3rd, 2011 by Many Ayromlou

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.… Read the rest

Quick Media Converter brings Windows GUI sanity to ffmpeg…..

datePosted on 14:28, August 25th, 2008 by Many Ayromlou

For those of you who’ve hated the opensource ffmpeg command line media conversion tool, here is Quick Media Converter. It’s a nice looking front-end for ffmpeg that hides the command line complexity of this swiss army like media converter. So What can you do with Quick Media Converter?

-Converting Video files from one format to another.
-Converting Audio files from one format to another.
-Extracting and converting Audio files from video or audio media.
-Extracting and converting Video without sound.
-Preview and/or listen to video and audio files with FFPLAY Multi format player (Fabrice Bellard).
- A myriad of formats is recognized by FFmpeg, those not recognized yet, are worked on by many people around the open source community and may most of the time, become available sooner or later.

CineForm Direct-to-Disk Recorder

datePosted on 12:10, December 10th, 2007 by Many Ayromlou


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.
