btiffin 5-Dec-2008 [2507] | screen may not be installed by default. And I think it may be best described as a multiple process enabled session multiplexor disguised as a teminal program |
kcollins 5-Dec-2008 [2508] | Another option is dtach, which allows you to detach from and reattach to a terminal session even if you completely disconnect from the machine in the interim. |
Graham 5-Dec-2008 [2509] | http://rebol.wik.is/Hylafax/Dtach |
Tomc 5-Dec-2008 [2510x2] | dtach looks alot like all I ever used screen for anyway |
thanks | |
Gabriele 5-Dec-2008 [2512] | or just >/dev/null </dev/null 2>/dev/null :-) |
Robert 6-Dec-2008 [2513x2] | Gab, yes of course ;-) that's the "through the desert on your knees" approach. |
Guys, thanks a lot. As always there is more than one way to do it. :-) | |
Henrik 10-Dec-2008 [2515] | http://linuxlock.blogspot.com/2008/12/linux-stop-holding-our-kids-back.html Interesting problem to face, if some people think Linux is illegal to copy. |
Kaj 11-Dec-2008 [2516] | Yeah, we're brainwashed by the intellectual property industry |
btiffin 11-Dec-2008 [2517] | I don't usually, as I like to remain gullible, but I'm calling bullpies on the original e-mail. |
amacleod 17-Dec-2008 [2518] | btiffin, Are you saying you do not believe the e-mail? I find it hard believe the pro-microsoft stuff but the ignorance of Linux I do not doubt. I taught HS in NYC for 6 years and most teachers were clueless of computers in general. |
btiffin 17-Dec-2008 [2519] | Yeah, I'm calling bull on the original, but it's just a spidey-sense more than faith in humanity. I did like the one comment mentioning some people thinking "it's illegal to erase Windows from my harddrive". |
BrianH 17-Dec-2008 [2520] | I've met people who think that what the original message said is true, so I think it's plausible. |
Pekr 19-Dec-2008 [2521] | Who has got better Linux support - AMD or NVidia? I am looking for MB with embedded gfx chipset, being able to utilise FullHD, so it has contain H.264, VC-1 hw codecs, and Linux must be able to support it ... |
Gabriele 20-Dec-2008 [2522] | I'm not aware of any video decoding acceleration on linux, though there may be ways to get it I guess. it surely is not mainstream. |
Anton 20-Dec-2008 [2523] | I would say NVidia. |
Pekr 20-Dec-2008 [2524] | thanks! |
Vladimir 21-Dec-2008 [2525] | I set up a system with AMD 780 chipset a month ago and put Ubuntu on it. Installed Ati drivers and it works :) Movies, 3d games.... It works.... Also tried same system with nvidia 9600 and it also works... Driver support is becoming better every day.... |
Pekr 21-Dec-2008 [2526] | this is good to know. What we are looking for is HW acceleration of H.264 and VC-1 support. |
Graham 21-Dec-2008 [2527] | That's confined to add on cards. I doubt you'll find that on motherboards yet. |
Gabriele 22-Dec-2008 [2528x2] | Vladimir, video works very well on Linux, but it is not HW accelerated AFAIK. The ATI driver seems to have some support of it (but I'm not really sure, just getting XVideo support working took many days...), but I'm not aware of any video player taking advantage of that. |
Petr, if you are writing your own video player, maybe you can do something, but don't expect it to be easy (well, maybe you can just stick to one specific version of the driver). Why do you want to do this? Isn't software playback good enough? 720p H264 works fine on this machine which is an old Athlon XP 2600+. Do you really need 1080p? If so, isn't a cheap laptop MB able to give you that in software already? | |
Pekr 22-Dec-2008 [2530] | Gabriele - I did rather extensive read on the minimal config of the thing, and it is like that: - we are looking for embedded solution, we are space limited for our device, so no place for external gfx card either - forget 1080p, unless you are about to use monstroze performance CPU, which will be power hog in a kiosk system - so - you have to use HW, which contains codecs directly - ATI 680G chipset is minimum, 780 or 790 is beeter. nVidia 8200 or 9400 (Ion platform), VIA S3 500 family, Intell Poulsbo chipset - with above, you don't need so much powerfull CPU, dualCore Atom would be able to play your video - this one page is a good reference - http://www.tomshardware.com/reviews/amd-780g-chipset,1785-3.html We are still investigating the situation. We started our work for Windows, but would like to move to Linux in the long run instead. We want to use ffmpeg project, but we will have to see, if its playback somehow utilises HW acceleration, or not. We will also look into projects like mplayer and VLC. Another problem I read about is, that so called HW acceleration is not always utilised. E.g. H.264 is not so clearly defined as mpeg2, and hence there is already plenty of videos, which are in MKV container, H.264, but using some super-set of features, which will not be supported by HW acceleration anyway ... so - lot's of work for us :-) |
Gabriele 22-Dec-2008 [2531x4] | AFAIK ffmpeg does not use HW acceleration. This may have changed though, I don't follow the project closely. |
if you're targetting an HW player, you will have to encode the videos yourself. HW codecs are very strict. | |
esp. with buffer sizes. | |
you should probably search for linux based video players and what they use. if it's embedded stuff, there may be good linux support, but don't look for that in Ubuntu :) you'll need to talk with the hw makers directly. | |
Graham 22-Dec-2008 [2535x3] | I have hardware acceleration working finally on my pc ... 1080p with no CPU load :) But only works with PowerDVD. Nothing else can get HW acceleration working for me. |
Using a cheap Gigabyte H4670 videocard ... and an Athlon dual core 3000 ... so a slow CPU. | |
I tried mplayer, VLC, fmpeg etc etc. | |
Pekr 22-Dec-2008 [2538] | Graham - you tried under linux? |
Reichart 22-Dec-2008 [2539] | So what is everyone's fav flavour of Linux now a days? |
Henrik 22-Dec-2008 [2540] | I only really follow Ubuntu these days. |
Anton 22-Dec-2008 [2541] | Kubuntu here. |
[unknown: 5] 22-Dec-2008 [2542] | Ubuntu |
Geomol 22-Dec-2008 [2543] | It's been years, since I used Linux on a daily bases. But Ubuntu seems to be popular among the young people at university. |
Kaj 22-Dec-2008 [2544] | Wolvix on the client here, Syllable Server on the server |
Graham 22-Dec-2008 [2545] | Pekr, windows |
Ammon 22-Dec-2008 [2546] | I have Gobo Linux (mentioned on Carl's blog) installed as dual boot here but I haven't taken the time to get my wireless working so I'm mostly just using windoze at this point. I'm thinking about installing Debian as they are usually really good at have drivers easily usable. |
Tomc 23-Dec-2008 [2547] | unbuntu |
Robert 23-Dec-2008 [2548] | Still, Debian. I like that you can start very small, has a very powerful package manager and works really great. |
Reichart 23-Dec-2008 [2549] | Gobo, Unbuntu, Debian So far three... I'm going to put together a list of applcation I run regularly, and then we can weigh this again... |
btiffin 23-Dec-2008 [2550] | Debian; The best development model, (ala REBOL). Deliver when ready and ignore the peanut gallery shouting "it's late!" ;) Off-topic; Sadly, my second favourite wiki-forum-chat-combo-thingy, TikiWiki, is moving toward the ever useless every 6 months release cycle. Not a valid model for a volunteer workforce, imho. |
PeterWood 23-Dec-2008 [2551x2] | I have installed Ubuntu but really don't use it much. |
A related question. Which desktop? I'm using Gnome. | |
btiffin 23-Dec-2008 [2553] | KDE; but I develop using GTK+ so I like the Gnomey bits too. |
Ammon 23-Dec-2008 [2554] | I REALLY don't like Gnome. I prefer to use Enlightenment but it has an extremely slow developement cycle and takes a while to get it configured to where it is really useful. It has it's downsides but I've never found a desktop/window manager that even comes close to what Enlightenment does. |
Reichart 24-Dec-2008 [2555] | Tikiwiki is actually a very cool concept, most people don't realize how cool it is....(it is a wiki that works offline). |
Will 24-Dec-2008 [2556] | rebol on this http://www.yoggie.com/blog/2008/11/23/yoggie-opens-up-its-miniature-hardware-firewall-why/ ? |
