Guy using overclocked RPI2 as a desktop replacement reporting in.
-360p videos work in the browser
-all videos work when streamed via script
-retro games work
Anyone else does the same thing for their light computing?
Any quality you want.
I lost my script to make screenshoots of frambuffer video. Scrot gives you black window.
It's nice, but you can't switch Ctrl and Fn in it, which fucking sucks. It took me over 6 months to get used to it. I have normal Crtl/Fn layout on my Thinkpad that I use when I'm outside.
At first I thought island keys would suck, but it turns out I can type on it as fast or even faster than on the original high thinkpad keyboard.
go to about config and search for the mediasource thing and enable it, and there's some other thing you need to enable, google for ”iceweasel mse h264" and there's some ghacks article IIRC
I wanted to do it, but soundcard is terrible - not only quality-wise, but sometimes it lags or even freezes completely. I think it's safe to say that this shit is unusable as everyday computing machine without external usb soundcard.
Kinda want to do that with a Creator Ci20
If I can build a mini SGI or DEC lookalike case for it, I'll be set.
With my huge monitor power consumption is the key. With everything hooked up my RPI2 setup draws under 40 W of electricity. If I used my thinkpad with that monitor it would draw 70+ W. I dpn't want to think about my PC and microwave oven.
What is the best PDF viewer for scanned images?
qpdfview seemed nice, but it ate my entire ram once I tried to zoom in. Okular is fine for most PDFs, but when they consist of high quality images, it takes ages for the application to load next pages.
Why the hell not?
Tested both zathura and mupdf.
They both perform worse than okular when the PDF cosists of high resolution scanned images.
-360p videos work in the browser
holy shit! that even more than 240p
-all videos work when streamed via script
via script? Impressive
-retro games work
The future is here!
>all videos work when streamed via script

Most convenient way is to use kweb3 browser.
It comes with omxplayergui.
Just visit any video site, navigate to video and hit play button. The video will open in movable omxplayer video and stream with any quality.
Of course 1080p video might be too much for RPI's weak ethernet, but you can always buffer ahead.
If you can live only with linux, then sure.
I need to boot windows from time to time just because I won't get Office 2010 to run on ARM.
For budget work processing machine, RPI2 is good enough in my opinion. Hell, you can use it as a terminal and connect to VM's that are running on the server.
HOW NIGGA? HOW?!
I fell for the meme and expected a 2006tier desktop PC, but it wont even play any video(except for, surprisingly, WebMs) without lagging like shit! I used Ubuntu Mint on it, if that matters in any way
after the big dissapointment I tried out OSMC and I'm VERY happy with that. I can stream movies, watch Youtube, listen to my music and that pretty fast
>I used Ubuntu Mint on it, if that matters in any way
Yes it does.
RPI2 with proper configuration, debian and correct overclock gives you decent performance.
To play videos use software that can utilize the GPU. With no hardware acceleration you will need all 4 cores to play videos.
Use this on RPI1
temp_limit=80 #Will throttle to default clock speed if hit.
Long story short,
Read how to overclock this shit, test if it's stable and then read how to configure your system to work fast. Default config is not that fast at all.
Upgrade your firmware.
I bough MPEG codec from their fucking store so that I could watch some of my downloaded videos faster.
Try opening the video using kweb3 and report back. Same thing for Iceweasel. I'm curious how will you perform.
And set up correct memory split. I have 128MB for gpu. The overclock setup posted higher is not the best my RPI can do, but I wanted it to be stable. I had some problems with 1100Mhz setup but later it turned out the problem was caused by pulseaudio, not the overclock itself.
Additional options in cmdline.txt
dwc_otg.lpm_enable=0 console=ttyAMA0,115200 console=tty1 root=/dev/sda1 rootfstype=ext4 elevator=noop rootwait
Don't touch root=
if you are booting from SD card.
JS can kill even more powerful machines.
thanks for the help senpai
about to try out everything
and yeah, my SD card could be one of the problems. it's just a class 4 Sand Disk(don't know about the read and write values. will test it)
Class 4 gives you 4 MB/s of transfer.
And you are complaining that something works slow? Dude...
I get 31,1 MB/s on USB SSD while watching the fucking youtube video at the same time.
Who knows? I use omplayergui to play videos, or Kodi or even Mplayer (on 4 cores) when I don't have accelerated codeds for that certain format.
Do I have to compile mpv from source?
Make sure that you are using a video player that supports OpenMAX.
Start with playing video with omxplayergui.
You will need youtube-dl and omxplayer installed. I'm taking a break.
I'm making a document, use pdfs as source, draw using a tablet, check out things on the web, manipulate images in Imagemagick, have fb chat opened in pidgin and everything still works fine.
>for like, schools and shit
In my opinion yes.
I use it for my academic projects and assignments.
Whenever I don't need large computing power to do stuff, I choose to do my work on RPI2.
Even when you do need to use a larger computer, you should have access to more powerful machines at an academic facility.
Whenever I needed to run simulations at university, I'd just SSH into the department server from my laptop and run them on their machines.
Yes I can remotely connect via SSH.
I still carry a ThinkPad x220 with me, because I never bothered to construct a portable shell for my PI. You still need a better machine to do some things in Visual studio or to model something chemistry/physics related.
I tested the class 4 card and it strangely had 8,3MB/s write and 19,6MB/s read
>pic related is the card
Just tested default package from Jessie.
It works like shit and in software mode
You have to compile proper version of mpv yourself.
If you are not downloading videos to RAM then writing them to /tmp might slow down everything.
Broadcom requires a firmware blob to boot the CPU. Therefore it is a dead end. Don't waste your time with it.
Plus they also "enable" their shit.
I think RPi2 is getting pretty close as a desktop replacement for many light-weight uses.
The CPU speed and RAM are pretty close to sufficient now.
The big remaining obstacle is the slowness of the SD card flash. If they can get that upgraded in the next generation (maybe add some on-board NAND?), I think that will balance out the system nicely and we'll have a feasible low-end desktop.
For the ports, I would say the one obvious omission is SATA. I think RPi will probably need to add SATA in the next release because a number of their competitors already have it.
tl;dr -- I think about one more year and RPi should finally have all the pieces in place to be a true low-end desktop replacement.
>Broadcom requires a firmware blob to boot the CPU. Therefore it is a dead end. Don't waste your time with it.
They will eventually open-source it.
The experimental GPU driver is open-source and it showed up recently.
Well, I mean if its hardware is known to work with upower rules and udev, etc., in addition to the kernel support. I own a RPI B and it's great for emulation, but the level of acceleration is very limited, especially with the memory it carries.
I wonder how anybody can stand watching one whiny bitch and one guy with no opinion on a subject, when both of them usually have no idea what they are talking about.
Man, I just want top tier mobile phone hardware in a small computer with a 2.5" SATA bay or or M.2 at a reasonable price, is that too much to ask for?
For internet drama, Mundane Matt, maybe Sargon or TL;DR, Bearing. For retro games, not that much channels just about talking, but talking about games without showing them is pretty stupid by itself. So LGR, RetroGameTech (bit inactive, but his videos are great), maybe even GameSack, even if their "research" is, let's say, limited. (This game is in Japanese, so we won't bother looking up the plot, which is translated on the wiki page) For a PC retro gaming (and general retro hardware) PhilsComputerLab is exceptional for his subscriber count.
The open source drivers don't replace the giant blob. You still need the blob for accessing RAM, booting, USB... it's essentially firmware for the entire SoC. There's another project to replace the blob itself but it's probably four or five years away from being useful.
I do the exact same thing, except I dont overclock.
Im very impressed that the Rpi works as well as it does for how cheap it is.
Im using it as my main desktop while I save up for a PC
I've successfully overclocked RPI2 to 1100MHz.
If you are afraid, set it to 950 or something.
By changing configs for your RAM you can actually feel the difference in speed.
is a protip
Usually no, because I usually use my phone when I want to watch videos, but I sometimes do when I browse /wsg/.
I just use the headphone jack to RCA, werks
You have any suggestions on getting audio out of the pi?
I think I might try overclocking, I didnt think I needed it before but Ill give it a shot.
I do have power issues sometimes though, the light goes off and I get the square and the whole nine yards, do you think that would be a problem?
I have no idea what that is
>I do have power issues sometimes though, the light goes off and I get the square and the whole nine yards, do you think that would be a problem?
Get some protection. Even if you don't overclock a sudden powe outage might fuck up your SD if you keep your filesystem on it. For overclocking get a usb hub with its own power supply and hook up rpi and everything else to that hub.
i want to plug my RPi2 to my trinitron so i can play retrovidya on it.
AM I FUCKED ? there's a composite V and a A stereo outpout, but it's on the same unique port.
If i get a splitter i can make it work so i can have Video and Audio at the same time or am i fucked ?
>a sudden power outage might fuck up your SD
its happened three times already ;-;
it seems to be fixed now though, hasnt happened in a couple months
A USB hub would protect it? That would just free up the power used by the keyboard/mouse wouldnt it?
Get a hdmi to "whatever you have cable"?
>That would just free up the power used by the keyboard/mouse wouldnt it?
Good hub gives you more power than regular usb charger. Check out my hub that I have posted in this thread. For best protection move your system to usb stick or hdd and set boot partition on SD card to be read only. Thanks to that the files won't get corrupted on sudden power loss.
>A USB hub would protect it?
It would protect it from power surges. Good power strip would do the same. Nothing other than a UPS will protect you from power losses.
I will look into purchasing one of these
Assuming you >>52927948
are OP, the one you use looks nice but I cant find one that delivers to US, Ill find something though
This sounds unneccessary due to my infrequent use of the rpi sound, but I will keep it in mind if my habits change
Sounds cool, Ill check it out
Yeah, power problems I have are just multiple little blinks when the pi gets overwhelmed, I think Im just going to get a hub
>Sounds cool, Ill check it out
Another not that obvious propsition i classic OpenXCom. Everyone knows emulators, but native linux ports can also be fun.
>Yeah, power problems I have are just multiple little blinks when the pi gets overwhelmed, I think Im just going to get a hub
You can see the rainbow square in the corner, right? Your rpi needs more power. Also powering power hungry devices directly from the pi is a bad idea. My logilink hub gives 5V 3A of power and it can give power to an ssd, rpi, keyboard, trackball, usb stick, external hdd, 2 gamepads and a running smartphone. Every combination of devices work and my RPI has overvoltage set to 4v.
How does this look anons?
I cant really seem to find anything better that
Previously I used UNITEK but it burned down during a storm.
Oh no, you've destroyed every single Linux user's hopes and dreams! They use something that's free! They must not be able to afford a Microsoft (TM) Windows (TM) Genuine Experience (TM)!
Seriously though, how is a bloated as fuck Windows installation going to fit on and run well on a Rasperry Pi?
Ups. This looks like a charger. I have Unitek that looks the same but has a usb slot on front to connect to the PC.
How will you transfer data from the hub to the RPI if there is no communication usb cable comming from the hub? If you only want to charge rpi from it than it's fine but you are wasting 5 usb ports.
okay now I see what you mean lol
That's a difference of a handful of dollars per year. Your monitor will be consuming far more power than your PC, be it an intel desktop or a raspi.
Calculate how much you're saving in energy per year, then calculate how much time you spend waiting for the raspi to perform tasks that would be done instantly on a more powerful machine. I guarantee that if you have a job, even at minimum wage, the time savings will outweigh the energy savings.
And that doesn't even touch the benefits of not gimping yourself to shit like 360p videos.
tldr; people who think this is saving them money are real tight jews.
"However, when comparing the results to newer Broadwell and Bay Trail processors, not only was the modern Intel hardware faster but it was also more power efficient than the two tested Raspberry Pi development boards."
I need large monitor space, ok?
2 smaller monitors draw more power than 1 40'' monitor. Are we clear?
I don't want to explain to you why having 2windows opened side by side boosts productivity. If you were a programmer you would know.
>then calculate how much time you spend waiting for the raspi to perform tasks that would be done instantly on a more powerful machine.
I can see no difference on task that I perform on my RPI. I'm not rendering videos on it you bloody fool.
Gex the gecko 1 on PSX.
I also play Rayman 2 right now.
There do many retro games you can run on rpi that i will have enough games for the rest of my life. Modern games are shit anyway. This is not /v/ so let me stop at that.
