Simple streaming the Linux desktop to Kodi using GStreamer and RTP

12th July 2018

Last night, I wrote +a +recipe to stream a Linux desktop using VLC to a instance of Kodi. +During the day I received valuable feedback, and thanks to the +suggestions I have been able to rewrite the recipe into a much simpler +approach requiring no setup at all. It is a single script that take +care of it all.

+ +

This new script uses GStreamer instead of VLC to capture the +desktop and stream it to Kodi. This fixed the video quality issue I +saw initially. It further removes the need to add a m3u file on the +Kodi machine, as it instead connects to +the JSON-RPC API in +Kodi and simply ask Kodi to play from the stream created using +GStreamer. Streaming the desktop to Kodi now become trivial. Copy +the script below, run it with the DNS name or IP address of the kodi +server to stream to as the only argument, and watch your screen show +up on the Kodi screen. Note, it depend on multicast on the local +network, so if you need to stream outside the local network, the +script must be modified. Note, I have no idea if audio work, as I +only care about the picture part.

+ +

+#!/bin/sh

Facebooks ability to sell your personal information is the real Cambridge Analytica scandal

21st March 2018

So, Cambridge Analytica is getting some well deserved criticism for -(mis)using information it got from Facebook about 50 million people, -mostly in the USA. What I find a bit surprising, is how little -criticism Facebook is getting for handing the information over to -Cambridge Analytica and others in the first place. And what about the -people handing their private and personal information to Facebook? -And last, but not least, what about the government offices who are -handing information about the visitors of their web pages to Facebook? -No-one who looked at the terms of use of Facebook should be surprised -that information about peoples interests, political views, personal -lifes and whereabouts would be sold by Facebook.

- -

What I find to be the real scandal is the fact that Facebook is -selling your personal information, not that one of the buyers used it -in a way Facebook did not approve when exposed. It is well known that -Facebook is selling out their users privacy, but a scandal -nevertheless. Of course the information provided to them by Facebook -would be misused by one of the parties given access to personal -information about the millions of Facebook users. Collected -information will be misused sooner or later. The only way to avoid -such misuse, is to not collect the information in the first place. If -you do not want Facebook to hand out information about yourself for -the use and misuse of its customers, do not give Facebook the -information.

- -

Personally, I would recommend to completely remove your Facebook -account, and take back some control of your personal information. -According -to The Guardian, it is a bit hard to find out how to request -account removal (and not just 'disabling'). You need to -visit -a specific Facebook page and click on 'let us know' on that page -to get to the -real account deletion screen. Perhaps something to consider? I -would not trust the information to really be deleted (who knows, -perhaps NSA, GCHQ and FRA already got a copy), but it might reduce the -exposure a bit.

- -

If you want to learn more about the capabilities of Cambridge -Analytica, I recommend to see the video recording of the one hour talk -Paul-Olivier Dehaye gave to NUUG last april about - -Data collection, psychometric profiling and their impact on -politics.

- -

And if you want to communicate with your friends and loved ones, -use some end-to-end encrypted method like -Signal or -Ring, and stop sharing your private -messages with strangers like Facebook and Google.

It is a single script that take +care of it all. + +This new script uses GStreamer instead of VLC to capture the +desktop and stream it to Kodi. This fixed the video quality issue I +saw initially. It further removes the need to add a m3u file on the +Kodi machine, as it instead connects to +<a href="https://kodi.wiki/view/JSON-RPC_API/v8">the JSON-RPC API in +Kodi</a> and simply ask Kodi to play from the stream created using +GStreamer. Streaming the desktop to Kodi now become trivial. Copy +the script below, run it with the DNS name or IP address of the kodi +server to stream to as the only argument, and watch your screen show +up on the Kodi screen. Note, it depend on multicast on the local +network, so if you need to stream outside the local network, the +script must be modified.
