webcasting stuff and such... - 12/03/02 08:55 AM

well last sunday's web cam party was kinda fun. looking forward to the next one. Here's some information for those that want to know a little more.<br><br>-The software that is required for somebody to webcast is QT Broadcaster. This is a free download from apple. Just click the Quicktime tab and you'll see a link to download this software. You can use a firewire DV camcorder, or a Firewire webcam like the iBot (but only if you have Jag). Other devices may or may not work, like USB cameras, and most likely you'll need a driver from IOExperts to get it to work (you'll also need a driver from IOExperts for the iBot if you have 10.1.5).<br><br>- QT Broadcaster can do a one to one webcast without the need of a streamer. If you are webcasting to somebody else on the internet, you and they will need what is called a routable IP address. If your computer is connected to a router or the Airport your Mac will have what is called a non routable IP address - it will most likely be in the form of 192.168.x.x. These kinds of addresses are non routable because many computers can share the same address in this range - it's used for local area networks. <br><br>- if you have a router and want a routable IP address, the easiest way is to put the Mac in something called the DMZ. Be warned that your Mac is now exposed on the internet for anybody to poke at, so you'll want to make sure that you have file sharing turned off and such while the computer is in the DMZ. Instructions for doing this will vary from router to router.<br><br> The Streamer <br><br>- The quicktime streamer is also free from Apple, and there are several flavors available to run on OSX, Windows, Linux and other Unix boxes, as well as source code for those that know how to compile source and run.<br><br>- The streamer is like a webserver, except it handles quicktime movies, both pre-recorded and live streams that come from the QT Broadcaster.<br><br> why use a stream server? <br><br>- The stream server can handle many to many connections simultaneously. Many people can be broadcasting and Many people can be viewing.<br><br>- The stream server we used was on a plain vanilla linux server that is located in Las Vegas at Intelligent Hosting. Since this server is on the internet all the mumbo jumbo about non routable IP addresses above does not apply.<br><br>- The linux box we used has a super duper connection to the internet. It's connected to the internet with a 1gigabit ethernet card that connects up to an OC12 and OC48 (which is like literally having thousands of cable modems). For example, at the peak of our web cam party the server's connection to the internet was about 4 Mbps and the server was only using 4-5% CPU resources.<br><br> more time to play <br><br>I'll be playing around with this stuff some more. I'll try out the QT streamer on my iMac and find out more on how to get it working. Also improving the delay time would be nice.<br><br>

Is there a way to fix the delay? Seems like if with all our connections it was only using 4-5% of the systems resources, there should be a way to get better timing...<br><br>[color:red]Hold on...it's time for a</font color=red><br>

thanks JC<br>Do you think you can post this at MC also, so they don't feel left out from your vast knowledge. I think there are people there that showed interest.<br><br>

I would, but there are too many people at MCF that turn every post like this into a little "I'm smarter than you pissing contest" at MCF.<br><br>Nothing is stopping them from coming here and reading it.<br><br>

Re: webcasting stuff and such... - 12/03/02 09:21 AM

I'm not sure. The delay is normal for webcasting. Where I work we make webcasting equipment with Real and MS encoders/streamers. The technology is designed so the players (QT player, Real Player, MS Player) buffer a few seconds of video when the internet connection drops momentarily. Sort of like skip protection on CD/MP3 players.<br><br>To get better response time, we might have to switch to videoconferencing type technology, and the QT Broadcaster does support H.263 encoding (videoconferencing encoding). The streamer might have to be changed, or maybe I can configure it differently. I still haven't read the documentation on all of this.<br><br>

JC, you don't ever have to worry about me pretending to be smarter than you! Dang man...I wish I had 1/10 of the knowledge about this stuff as you do!<br><br>I can't wait for the next one..but can we not make it so late and preferably on a weekend night? Say a friday or saturday? Thanks..<br><br><br>Also, we need to get Sherman and others up to speed.<br><br><br>[color:red]Kiss My Banana!</font color=red>

well, i did the DMZ thing JC said. hmmm. i just am not ready i suppose. <br><br>i did have my computer tell me that another firewall was running on my machine -- when i clicked on the firewall tab in sharing in the system panel. perhaps some secret firewall has taken over somehow. hmmm again. i can't find it in the process viewer. <br><br>thanx for trying.<br><br>[color:blue] -sean</font color=blue>

You don't have a router, do you?

Re: webcasting stuff and such... - 12/03/02 08:27 PM

He already made it a DMZ which should bypass the router's firewall but i might be wrong.<br><br>
Posted by: DaddyMac

Re: webcasting stuff and such... - 12/03/02 08:38 PM

Yeah, but if you do the DMZ thing just on OSX's firewall, it won't mean squat if there's a router there...<br><br>Just asking...<br><br>[color:red]Hold on...it's time for a</font color=red><br>

Do you want a screenshot of my settings? I'm on a Linksys, and I didn't set anything special besides that 8000 port thing in the Quicktime prefs...<br><br>[color:red]Hold on...it's time for a</font color=red><br>

Re: webcasting stuff and such... - 12/03/02 08:52 PM

it might be easier to just plug the mac you will be using for the webcasting into the cable/dsl jack directly while you are webcasting (just to see if it works). Once you know it works for sure, you can then begin to narrow down the possible headaches.<br><br><br>Visit me here!

Re: webcasting stuff and such... - 12/03/02 08:53 PM

well, i did turn off all file sharing before doing this and i have now turned off DMZ so you'll have to get past the router, too. somehow, i get the feeling that my IP number is more likely to be targeted randomly by someone than by someone finding it on this forum. <br><br>[color:blue] -sean</font color=blue>

Re: webcasting stuff and such... - 12/03/02 08:55 PM

are you talking about the other night? Cause you were streaming through JC's server, not your own.

Re: webcasting stuff and such... - 12/03/02 09:04 PM

Actually, you're dead wrong about that Sean. I used to visit another forum frequently. This forum would post your IP address at the bottom of each post (kind of a way to keep people honest and "nice")<br><br>Just after I upgraded to OSX, I got hacked. I found a few strange files in my "sites" folder in the Users folder. Somebody from the forum hacked in to my computer and left the files for me (he wasn't a jerk, he actually just edited a photo I had and left a text file saying he didn't mess with my system, but wanted me to know how easy it was to get into my computer once he had my IP address.) The next day, there was a whole bunch of people in the forum that had the same thing happen. Shortly after everyone posted about it, the website changed the code in the forum to not show IP addresses.<br><br>The thing that keeps you and I safe is...

except "your very large porn collection!"<br><br>hey...you really did get into my computer. hmph!<br><br>so, how easy is it to get into a computer behind a router if i don't have any ports open to find my particular machine behind the router (at least not any easier than any of the other 4 computers online now)?<br><br>[color:blue] -sean</font color=blue>

Re: webcasting stuff and such... - 12/03/02 11:13 PM

If i remember right the router will drop any unrequested packets such as someone scanning IP addresses, so your pretty safe on that end. However if you download a file you think is safe (i.e. email attachment) that contains a trojan or virus it is possible for it to open up holes in your system for people to hack your computer trough. I don't know if this is right but i think it is.... <br><br>
