Re: Anyone done a live video broadcast thru Linux?
by David Spake 24 Jul '05

Chris, Thanks for the suggestion. I've looked hard at Helix and Darwin Streaming Server, but am hesitant to bite just yet. I like StreamStudio, but it appears to be a dead project, and I may have to default back to Darwin or Helix. My main concern lies in that so many of the streaming solutions assume you are doing a true capture thru a capture card, or file serving a feed. I'm trying to do something different in that I'm focusing on a live feed, with as little lag as possible. The live connection puts in a set of issues that I just don't see addressed that often. From my reading, I'm hoping to use a camcorder with a Firewire (IEEE 1394) connection to do the heavy encoding lifting. One of my real questions is how much processor load will I realize by converting from the DV combined audio/video format to something like quicktime, thedora, real, whatever. Will having a capture card with embedded decode on it help? If so, how much? I am hoping that the CPU hit will be less for a conversion than a true encoding, but it's hard to say. The reason I want to lean so much on the dv/1394 solution is that it's a lot easier to find camcorders to borrow than dig up four capable encode/decode capture cards. But those two links I've already bookmarked after browsing thru and will read them in much better detail. I have no doubt the forums will provide me a wealth of information, and I can't thank you enough for the leads. It seems almost anymore that even as good as the search engines are, a lot of the deep forums aren't indexed anymore. Whether or not it's from neglect by the search engines, or that the forum owners don't want the deep linking I don't know. At the end of the day I'd love to use a more well known, possibly stabler solution than an unknown one (StreamStudio), and Darwin Streaming Server has a lot of attention and admiration. I appreciate the information, and the links, and wish you the best of luck.

RE: IPcop config
by Kelsay, Brian - Kansas City, MO 22 Jul '05

Ed is right. I would've responded sooner, but I was off work for a week and have been buried in email and work all week. Remember to upgrade to 1.4.6. If you have a 1.4.0 or 1.4.2, this is a multi-step upgrade. You must get 1.4.3 and 1.4.4 on and then reboot. Then add 1.4.5 and 1.4.6 and reboot. The reboots are for the kernel upgrades. If you plan on making big changes, get the 1.4.6 .iso file and sove yourself the trouble of the upgrades. If you have a ton of custom firewall rules that you have put in to block sites or attackers, then keep the current install, change the config and do the upgrades.

I would say reinstall. I have never done dialup so, I don't know what to turn off to stop dailup. It really doesn't take that long to reinstall anyways. Thanks, dj

Anyone done a live video broadcast thru Linux?
by David Spake 22 Jul '05

22 Jul '05

Greetings all, I've helping to put together a conference next year at the Airport Marriott and would like to live stream some of the breakout sessions over the net. I can find all sorts of file served broadcast solutions, but finding a live solution is something else, especially coupled with the firewire and miniDV format. Hardware I envision is 4 camcorders, for the video signal, running into 4 linux boxes. The linux box's primary purpose would be to convert the DV format to something streamable (Thedora, quicktime, Real, something) and send it to a central (on site) server. This central server would then send the converted signal to a paid for remote server that would actually serve the signals to the audience. It would also serve at least one other box that would serve as registration, and possibly one more if we wanted to handle live questions (via email) from the internet audience. As some of the sessions will be panel discussions, I'll be running them thru a mixer, then running into the linux box, but that shouldn't be that big of a deal. With the camcorders doing the heavy lifting of encoding, I wouldn't think I'd need much in the way of processing power, but that's one of the things I need to figure out. Especially CPU load in converting from DV to something else. Although the Marriott only has a single T1 line, I think I can get an acceptable signal to the audience. Your thoughts on possible solutions and potential pitfalls would be appreciated. Dave

RE: CodeWeavers "throwing down the gauntlet"

--- >>...improve Wine until it can run nearly every Windows program... --- I didn't switch to linux to run all my windows apps on it! --- I think the point was kind of missed. If you cannot evaluate the competition's software/applications side-by-side it is not a very good comparison. Also, admit it, the majority of people on this list are well above average when it comes to technical acumen. If Linux is to really catch on like wildfire as a desktop replacement then is really should become a universal OS. It will need to run any desktop application from any desktop OS. Think about it this way - If you moved to Florida (or your favorite location) and the requirements to live there were that you HAD to paint your house a specific set of colors, it had to be build a certain way, and you had to wear reed skirts with a tank top and flip-flops only a few people would find that appealing. Now, it the clothing and housing restrictions were removed, move people would live there. Pretty much the same thing when it comes to the desktop environment. Please note, I am making a distinction here. Desktop vs. Server. My two pence. - Michienne

CodeWeavers "throwing down the gauntlet"
by Richard A. Franklin 21 Jul '05

21 Jul '05

"We are on a mission to improve Wine until it can run nearly every Windows program, and we would like your help". http://www.codeweavers.com/ As a desktop / home office user, I have been quiet on this list for some time. That is sort of a good news bad news thing from my perspective, as it means that my desktop experience with Linux is now "adequate" with my favorite distro, however, I am not diving into diminishing returns (time and effort) in any attempt to make it all just a little bit more functional, and I had not seen any great leaps lately in desktop Linux in general. By "lately" I mean in Linux time, which involves rapid changes and frequent updates, not Windows time, which means an occasional download to get a new band aid to place over the last band aid. No major questions. It all seems rather user friendly now (I need that), certainly when compared to that boxed distro I bought a few years ago that claimed to be a complete OS replacement. Oh, and I consider that to have been a lie at that time, although these days it is fashionable to refer to such wild claims as a gentle spin. ANYWAY, the CodeWeavers installer challenge looks promising. If it resulted in just a couple of Windows programs working for me without Windows (including a couple of games written after 1997), then I would be done with Windows! Rick

Hardened PHP?
by Gerald Combs 20 Jul '05

20 Jul '05

Has anyone tried the PHP hardening patch (http://www.hardened-php.net/)? If so, how well does it work? Also, is there a way to do Perl-style taint checking in PHP (or Python, for that matter)?

live broadcast

listening to the live broadcast (with iTunes on XP, since my Mepis box is getting a new mobo). too much background chatter hard to follow the conversation (is there a topic tonight? I tuned in late) thanks! Rick -- No virus found in this outgoing message. Checked by AVG Anti-Virus. Version: 7.0.323 / Virus Database: 267.9.2/52 - Release Date: 7/19/2005

Good supported wireless desktop adapter
by brad 17 Jul '05

17 Jul '05

I just moved from a house that was wired with cat 5 to a house that is not so I am needing a couple of wireless adapters for my desktops. I have not played with any of these in Linux so I was wondering if anyone has any suggestions for a well supported adapter? I am running various Fedora flavors. I need 802.11G and probably an external antenna since the firewall and AP are in the basement and the desktops are on the 2nd floor. The cheaper the better as well. TIA, Brad

Buzzword of the Week: MVC? (Was: Ruby on Rails / Web Technologies)
by D. Hageman 16 Jul '05

16 Jul '05

I noticed that someone already posted on MVC framework that was written in perl, but this one apparently one the Linux Journal Editor's Choice Awards: http://maypole.perl.org/ Is it just me or has the MVC buzzword really become popular these days? I do quite a lot of programming and I just can't seem to get excited about it. ;-) //========================================================\\ || D.

It should just be a network reconfig. Simply login as the setup user. That will automatically take you to the configuration menu where you can select the network and pick which interface is which "zone".
