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. NIMBUS: The WiMi6400T and WiMi6400R provides high quality Full HD encoding/decoding function with low latency of 40ms for encoding and decoding, each. It supports wide range of encoding rate from 1Mbps ~…

Streaming 1080P video using Raspberry Pi (or BeagleBone Black)

Apache, BeagleBone Black, C920, CLI, DIY, embedded OS, Linux, Opensource, Raspberry Pi, Streaming, Tutorial, Video
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…

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…

How to stream live HDV/DV to iphone…..

Apache, HDV, iPhone, iPodTouch, Linux, Macintosh, OSX, osx Server, Video, VLC
In this guide I'll show you how to stream live HDV/DV video to your iphone using a linux box (Ubuntu 9.10) with firewire input running vlc/ffmpeg and a Imac with OSX 10.6.2 running mediastreamsegmenter and apache2. Start out with the iPhone streaming media overview. Without understanding this document you'll have a hard time getting things working. First things first, you need to have a working Ubuntu 9.10 machine. I'm using a small footprint 2.4Ghz Core2Duo machine with PCI firewire 400 card in it. For video input I'm using a Canon HV30 set to HDV mode (1080i/60) connected via firewire. Next you need to follow the instructions on this page (steps 0-5) to get a working ffmpeg with x264 and aac encoding. Without this working you're not going anywhere....sorry. If you're…

Movist…..will it be the next VLC for mac….

Apple, Macintosh, Opensource, OSX, osx Server, Video, VLC
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 :-).

DisplayPort does true 4K video….plus other stuff….

DCinema, DisplayPort, Video
Well, it's taken a bit of time, but I think with the announcement of DP1.2 specs last December, the specs (and hopefully soon the vendors) are ready for True Digital Cinema home implementation. The DisplayPort connector supports 1, 2, or 4 data pairs in a main link that also carries clock and optional audio signals, each with a symbol rate of 1.62, 2.7, or 5.4 Gbit/s. The video signal path supports 6 to 16 bits per color channel. This allows the updated DisplayPort 1.2 specification to drive 4K x 2K display (3840x2160) with 30 bits per pixel and 3D over a single 2m cable.DP 1.2 supports a maximum of 5.4Gbps per lane, with 4 lanes providing a whopping 21.6Gbps throughput, more than enough for 10-bit 4xHD resolution (3840x2160). To achieve…
