Sun Micro Systems - Scott McNealy , First Global Internet Stream Decembe...





Sun Micro Systems - Scott McNealy , First Global Internet Stream December 1992.

I need a old copy of Solaris 2.4 or 2.5 on a SparkStation or emulator to capture an Mpeg4 of this.

player will play TESTME or holliday greeting 1992 files out to local audio and standard Xwindow.

Still looking for the source code for these.

This should be a precursor to : Sun's CellB Video Encoding rfc2029

http://www.cs.columbia.edu/~hgs/rtp/drafts/draft-ietf-avt-cellb-06.txt

"CellB, derived from CellA, has been optimized for network-based video applications. It is computationally symmetric in both encode and decode. CellB utilizes a fixed colormap and vector quantization techniques in the YUV color space to achieve compression."

I came in and implemented that change to there codec in a few days, and did the stream, I have no idea what happened to that code after I left my brief contract in 1992.

Puffer (puffer.stanford.edu) is a free and open-source live TV streaming website

Puffer (puffer.stanford.edu) is a free and open-source live TV streaming website, and also a research study at Stanford University using machine learning to improve video streaming.

More details can be found on the website, in our research paper (Community Award winner at NSDI 2020), and in the documentation.





Stream live TV in your browser. There's no charge. You can watch U.S. TV stations affiliated with the NBC, CBS, ABC, PBS, Fox, and CW networks.

Puffer works well in the Chrome, Firefox, Edge, and Opera browsers, on a computer or an Android phone or tablet. Puffer does not work on iPhones or iPads or in the Safari browser.

Puffer is a research project in the computer-science department at Stanford University. Please see the FAQ and our research paper (Community Award winner at USENIX NSDI 2020) for more information.

StereoPi - companion computer on Raspberry Pi with stereo video support
https://diydrones.com/profiles/blogs/stereopi-companion-computer-on-raspberry-pi-with-stereo-video-1


 Compute Module 3 for playing with stereo video and OpenCV. It could be interesting for those who study computer vision or make drones and robots (3D FPV).
It works with a stock Raspbian, you only need to put a dtblob.bin file to a boot partition for enabling second camera. It means you can use raspivid, raspistill and other traditional tools for work with pictures and video.
JFYI stereo mode supported in Raspbian from 2014, you can read implementation story on Raspberry forum.
Before diving into the technical details let me show you some real work examples.
1. Capture image:
raspistill -3d sbs -w 1280 -h 480 -o 1.jpg
and you get this:

You can download original file here.
2. Capture video:

raspivid -3d sbs -w 1280 -h 480 -o 1.h264

and you get this:

You can download original captured video fragment (converted to mp4) here.
3. Using Python and OpenCV you can experiment with depth map:

For this example I used slightly modified code from my previous project 3Dberry (https://github.com/realizator/3dberry-turorial)
I used this pair of cameras for taking the pictures in examples above:

Just a test site for now, but you can do channel changing. 

If anyone has any live streaming video or audio URL's for youtube, twitch or else where please comment here and I will  add them. 

I just need an plain webpage or an URL I can drop in an iframe html tag.

One negative review of xsplit.

Frustrated doesn't even come close to what I'm feeling. I'm using OBS and X-split to make my videos and X-Split is giving me fits. I'm pretty done with it! The audio and video continue to be out of sync even though I've micro adjusted the settings, gotten a new hard drive, high speed internet and now use an ethernet cord. WHO KNOWS WHAT OTHER SOFTWARE I CAN USE BESIDES XSPLIT??? I have my debit card ready, lol.
*Note unless you know what I'm talking about, it's ok, please  don't worry about it. 
**And NO, I'm not messing with Xsplit anymore right now. 
😬😖😩
