Mystery Science Theater 3000 is sort-of back…

“Mike Nelson – the comic genius behind MST3K – has launched a new site called RiffTrax, where he provides an audio commentary track to mainstream films that you can download and listen to while watching the movie.”

For just $1.99 (beta pricing!) you get a commentary track for a growing number of movies…really really great stuff.

udp multicast to tcp unicast proxy YAPS revisited…and bugfixed

Yesterday I had an idea how I could fix the last remaining problem in my udp multicast to tcp unicast proxy server (YAPS).

The last time I had to report this:

“There are some glitches I am afraid to say: one known bug is that there are 12 bytes to much in the outgoing data stream which corrupts the picture. If anyone here can fix it: Do it please ;) I tried one day and I could not find a solution for the problem.”

My idea was now, that those glitches are possibly there because some bytes of the header remain in each packet and therefore the movie stream itself is destroyed. MPlayer was able to display something, but as I said…glitches.

So I made a method that actually calculates the size of the header of each RTP packet and then removes this header:

   1:  public byte[] killRTPheader(byte[] b,ref int inlength)
   2:  {
   3:  byte[] outbytes = new byte[1600];
   4:  int headersize = 12+4*((b[0] >> 0) & 0x0f);
   5:    Array.ConstrainedCopy(b, headersize, outbytes, 0, inlength - headersize);
   6:    inlength = inlength - headersize;
   7:  return outbytes;
   8:  }

The results speak for themselves: A perfect sound and picture.

Beside that I added some additional features. Read the source and you’ll find out.

Weizenbaum. Rebel at Work.

Peter Haas and Silvia Holzinger did a film called “Weizenbaum. Rebel at Work.” and I think you should hear about it:

“The film spans 8 decades of Joseph Weizenbaum’s life. It provides a stage for his humorous narrative depicting a World of Yesterday while reflecting on the dawn of the computer age. It follows 83-year-old Weizenbaum on some of his numerous public lessons, effortlessly entertaining overcrowded lecture halls.

The old man is an up-to-date chronicler, a chief witness against militarism and the myths of technological progress, but he remains a modest, funny and most reflective story teller.”

It’ll be available in german language in august and later this year in english.

meet the Jetsons: a new type of elevator

Have you ever seen the Jetsons? If so, you might remember the vacuum elevators. Well. If you ever wanted to have one of those, you can now:

“It is our self-supporting vacuum elevator; a light and resistant structure built with aluminium and polycarbonate. By simple principles of physics; the difference in air pressure above and beneath the vacuum elevator cab literally transports you by air. It is the vacuum pumps or turbines that pull you up to the next Floor and the slow release of air pressure that floats you down.

Pneumatic Vacuum Elevators are easier to install, maintain, and operate than traditional elevators. They are especially ideal for existing homes due to their compact design because excavating a pit, and hoistway are not required. Air pressure above and beneath the elevator cab are the key to transporting.

The reliability and safety of these vacuum elevators are unsurpassed due to the physics behind the design; it is virtually impossible to get stuck between floors, or freefall.”

the world championship live…in your telnet terminal…

When you don’t have the chance to watch the football world championship live on tv, you can watch it on a very nerdy way: ascii-art telnet livestream.

You cannot deny the similarities to the actual tv picture…but you need to be very nerdy and/or very desperate to watch it this way…

is it about pr0n and other adult entertainment: Second Life

I joined second life some days ago to see what all the fuzz is about. And the first impressions I got is: there’s a shitload of pr0n and adult entertainment.

Being in Second Life for 10 minutes I met “Lucas Pow” on an island …

Yet another proxy server… how to turn multicast into unicast…


We are using multicast to deliver more than 20 MPEG-2 encoded video+audio streams in our network. The advantages of using multicasting in a network of more than 2000 machines are well known. But there are several scenarios when multicasting is not the right choice.


For example: in wireless environments you have to use some sort of multicast group management which is not always as flexible as a more simple solution. You would end up multicasting all 20 streams into the wireless network – which would just explode or something. (our multicasting traffic volume is around 125 Mbit/s…which is… quite much)


I started writing such a solution two days ago and now I want to make the first lines of code available for everybody to try out.


To speak simple: it’s just another proxy server. It’s a HTTP Server that can be triggered to join a multicast group (hardcoded in this version) and forward the traffic from that multicast group directly to the client that asked for it. It’s as simple as it can get and to be more technical: the proxy receives udp multicast packets and sends them as tcp unicast packets.


When you tell MPlayer to trigger the proxy by asking for /hr.ts you would get something like this (if you have a multicast group on that IP/Port):



As you can see: MPEG2-Transport Stream inside. So it works as designed. There are some glitches I am afraid to say: one known bug is that there are 12 bytes to much in the outgoing data stream which corrupts the picture. If anyone here can fix it: Do it please ;) I tried one day and I could not find a solution for the problem.


Anyways: It’s doing what it’s supposed to do. And that’s why I am making it available for everyone:


Sourcecode: YAPS.zip (11,18 KB)


It compiles with Microsoft.NET 1.1/2.0 and Mono. There’s a Visual Studio 2005 solution file inside to help you compile it. (Should work with Visual C# Express Edition). Oh… and I am releasing it under the BSD license which is included with the package.

SD-card slot TV-Tuner (SDIO) available soon…


I could imagine some uses for this. It’s a tv (pal/ntsc) tuner for Windows Mobile devices (Pocket PC 2002-WM5) and it’s got some quite interesting specs.


The 1200mAh battery that comes with the tuner only stays 2.5 hours and it’s only got a maximum framerate of 20 fps – but that’s for the bad news. It’s finally a tv tuner for your mobile gadget!!!

distributed video encoding solution


More than a year ago Matthias Eller and Karsten Donat created a distributed video encoding solution that actually works.


As far as I know they were in desperate need for computing power to encode all the documentaries that Karsten recorded every day (he recorded almost everything that was broadcasted on german free-tv).


So the idea came up to split a single raw-video into a number of parts and let many machines encode these parts automatically. Then these encoded parts are copied back to the server and put together to the now finally complete encoded video.


We’re not using this at the moment for any encoding – but I thought it might be a great idea to write about it ;)



this is the tool to setup a new encoding task that is
submitted to the distributed encoding server


You can get this great tool-set at Matthias’ Website: http://www.static-void-main.de

what’s the deal with Sonys UMD and why a portable Media center is far better


I don’t want to compare anything else but the media playing capabilities of the devices. Since Sony is working together with many movie studios these days to make more and more movies available on it’s own proprietary format UMD.

The Sony UMD is simply a standard DVD with 60 mm diameter and 1.8 GByte of storage space. The fact that the disc itself is in some kind of caseing and the fact that there are legal issues if you would try to burn your own UMDs makes it not the media of choice if you want to burn your own movies or recordings to watch them with the PSP. The second media type you could use with your PSP is the Sony MemoryStick. One disadvantage of the MemoryStick is that it’s quite expensive. Around 90 Euro for a 1 GByte MemoryStick DUO is quite a lot money.


Sony UMD


The PSP can play some MPEG4 formats and there are tools/encoders available to create your own movies. But you’re limited to the size of your MemoryStick. Actually there are no tools that allow you to “syncronize” automatically with your video recorder/media center/whatever-media-recording-device. I don’t want to compare the possible video resolutions because they depend on that Portable Media Center you are buying/using.

A different storage idea is behind the Portable Media Centers. These devices commonly use harddisks with about 20 to 40 GByte of space which makes more than 20 to 50 hours of video. The medias are stored in the Windows Media formats like Windows Media Audio (WMA) or Windows Media Video (WMV) (there are some more formats like AVI…but the codecs are very limited…but more to this issue later…). There is an automatic synchronisation software available for the Portable Media Centers. This software even transcodes your media files to WMV/WMA while synchronizing. For me this is the strong argument for the Portable Media Centers: I can sync a PMC with my own recordings for example from my PVR… – I don’t need to buy expensive MemorySticks and do everything manually. I just put the PMC into it’s cradle and it’s going to sync my latest tv recordings for example… It’s the same thing like podcasts and the iPod. The more comfort you get the more you will use the product…

A big advantage of the PSP is that Sony tends to be more open to codecs and new codec developments. For example: The latest Firmware update for the PSP enables H.264 on the PSP… that’s one thing only future versions of the PMCs would have (as far as I know).

Another type of device – the normal Windows Mobile Devices – is not part of this article – but as I wrote some hours and weeks ago there is the same sync functionality built into current devices using the Windows Media Player 10. But if you want to play other formats with other codecs (like MPEG4) you have to use other Software Players like The Core Pocket Media Player.

One last thing: I really don’t get the idea behind the Movie UMDs. Who wants to buy a movie for about 15-30 Euro in a format he can only play in his PSP when you can get the DVD for about 8-15 Euros…I don’t think that this will work for Sony…actually it does not work for me.


BTW: I know…it’s mostly illegal to copy the movie from the DVD to your PC to copy it onto the PMC… but life is not a tickling competition…
