  • Fastest bit-blit in C# ?

    - by AttackingHobo
    I know there is Unity, and XNA that both use C#, but I am don't know what else I could use. The reason I say C# is that the syntax and style is similar to AS3, which I am familiar with, and I want to choose the correct framework to start learning with. What should I use to be able to do the most possible bit-blit(direct pixel copy) objects per frame. EDIT: I should not need to add this, but I am looking for the most possible amount of objects per frame because I am making a few Bullet-Hell SHMUPS. I need thousands and thousands of bullets, particles, and hundreds of enemies on the screen at once. I am looking for a solution to do as many bit-blit operations per frame, I am not looking for a general purpose engine. EDIT2: I want bit-blitting because I do not want to exclude people who have lower end video cards but a fast processor from playing my games.

  • Why does sound stop working after a while?

    - by badp
    I don't know how to reproduce this problem, because I don't regularly play music or sound. All I know is that, sometimes, I'll load a video (from youtube or from a local file) and there will be no sound. Everything looks fine software wise: Rebooting always fixes. aplay, paplay and pals give no error message I'm not in the audio group, as advised The device exists and appears in use: $ lsof /dev/snd/by-path/pci-0000\:00\:1b.0 COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME pulseaudi 17313 badp 23u CHR 116,10 0t0 7628 /dev/snd/by-path/../controlC0 pulseaudi 17313 badp 30u CHR 116,10 0t0 7628 /dev/snd/by-path/../controlC0 Restarting pulseaudio or alsa seems to do no good. What is wrong here?

  • Best way to store motion changes to reduce memory

    - by Andrew Simpson
    I am comparing jpeg to jpeg in a constant 'video-stream'. i am using EMGU/OpenCV to compare each pixels at the byte level. There are 3 channels to each image (RGB). I had heard that it is common practice to store only the pixels that have changed between frames as a way of conserving memory space. But, if for instance/example I say EVERY pixel has changed (pls note i am using an exaggerated example to make my point and i would normally discard such large changes) then the resultant bytes saved is 3 times larger than the original jpeg. How can I store such motion changes efficiently? thanks

  • There's no Sound Mixer menu, missing menu option in Sound Recorder

    - by AlexN
    I am using: -Ubuntu 11.10 -Skype -PS3 Eye Toy camera to input video and sound This setup has been properly working in former Ubuntu releases. To use the mic already built in on the PS3 Eye Toy camera I open de Sound Recorder app (notice: not inside Skype, from inside Skype it is not possible to do this) that is included in Gnome and then I go to FileSound Mixer, from this menu I can choose Gnome to get the input audio from the PS3 Eye Toy, instead of from the Audio-In of the computer. Now in Ubuntu 11.10 this Sound Mixer menu inside Sound Recorder is missing, Gnome says something like this: gnome-volume-control is not installed in the proper directory Note: I have tried this on Unity, Unity 2D, Gnome Classic, Gnome Classic 2D and Gnome Shell. In all of them the problem is the same. What can I do? Basically what I want to do is to be able to tell the computer to get the audio in from the PS3 Camera. Thanks in advance.

  • Is a program linked against an LGPL library in linux still under GPL?

    - by Jonathan Henson
    If I were to write say, an embeded linux video server, how much of the code do I have to offer to someone who requests the source? Do I have to offer the code that directly links against the GPL covered code or do I have to offer all code? For instance, if I use gstreamer, or any other LGPL code, on a linux platform in my program, does all of my code become under GPL simply because somewhere in the chain, the LGPL program had to link agaist GPL code? I guess this is an extension of the question. Can you write a C library that compiles in linux that does not become subject to GPL?

  • How can I inform search engines that the usefulness of some content on my site has a limited shelf life?

    - by Tim Post
    Let's say that I run a forum dedicated to computer hardware. Naturally, people are going to ask questions like: What is the best laptop for running [os] Or What is the best video card for under [amount] These may be perfectly fine discussions, but the content loses usefulness over time. An answer to either question asked in 2007 might still be relevant in 2008, but definitely not in 2012. Is there a way that I can tell search engines that certain pages might not give visitors what they're looking for after a certain date, and perhaps hint to a page on my site that would provide good information? Perhaps something I could set in HTTP response headers, meta tags or even a site map?

  • ".ts " files not recognised

    - by Keith Gardner
    I have some .ts files (programs recorded from my Sharp TV on USB stick) that I want to store/play on my PC. However, although they are listed on the stick when its plugged in the PC nothing will recognize the files. I have tried VLC (the "slider" moves but there's no sound or video) and changed the extension to MPEG, MP2, etc. but no joy. I have tried converting the files with file converters and demuxers but none of these recognize the files. Are the files corrupted (they play on the TV) or do Sharp have a unique file structure? Any help would be greatly appreciated.

  • How to include high resolution version of thumbnail

    - by neak
    I'm running a tube site that has a thumbnail for each post/video (running via Wordpress, 500k posts). When I first created the thumbnails they were a fairly large size, around 640px in width each and because of that I was seeing a lot of traffic from Google Images. After streamlining the site and resizing all of the thumbnails down to 170px rather than scaling them down I'm worried that Google isn't going to rank the images as high as they would be at a larger resolution, so is there a way to include the higher res versions and serve them to be indexed instead of the smaller ones?

  • Radeon HD 6290 terrible performance on a certified laptop

    - by dac
    I bought Asus K53U laptop, which is Ubuntu certified with pre-installed 11.10. The graphic card is Radeon HD 6290 but 720p playback is terrible. Even page scrolling in Firefox is very laggy. Proprietary drivers are installed by default. How is this possible, why is the laptop Ubuntu certified if the performance is poor? Any solution to this? I just did apt-get autoremove, and after that, this message came out in terminal: Error inserting vesafb (/lib/modules/3.0.0-15-generic/kernel/drivers/video/vesafb.ko): No such device Could that be the problem?

  • Where to start? (3D Modeling)

    - by herfus
    I'm looking for a good resource to start learning 3d modeling. I'm looking for something that starts with the basics (e.g. terminology; what are quads, triangles etc.) before/while going into the actual modeling. Book, website, video, anything will do. I'm only concerned with the quality of the tutorials, how thorough they are. I have experience with texturing, level design and so on - but I've never created anything more than simple shapes/editing existing assets.

  • ways to program glitch style effects

    - by okkk
    Most tutorials for generating glitch art usually has to do with some form of manipulation of the compression of files. Should my goal instead to replicate the look of these glitches in shaders or is it somehow possible to authentically generate the compression artifacts in real time? Example: This effect which I'm particularly interested is referred to as datamoshing. It does "things" using the p-frames of a video (frames that I think store just the change in pixels). I feel like I need a better understanding of both graphics programming and data-compression.

  • Thinkpad T530 with Optimus and Docking Station

    - by Vic Boudolf
    I have a Lenovo Thinkpad T530 with Optimus video, which is not supported on 12.04.1. I don't normally need the discrete (nVidia) graphics, so I turn it off in the BIOS settings to achieve longer battery life (and so that the screen dimmer will work), but when placed in the docking station, the integrated (Intel) graphics don't power the HDMI ports. (The VGA port does work, but I want to focus on the HDMI.) This means I have to change the BIOS settings constantly. Is there any way to have the system detect the docking station and power up/enable the discrete graphics accordingly? I don't need to do it on the fly. Just at startup. This post suggests that bumblebee can turn the discrete graphics on and off for specific applications, but I just want to turn it on or off. [2 suggests that vga_switcheroo will not work with nVidia Optimus.

  • DDDSouthWest 4.0 26th May 2012 - Async 20/20 presentation

    - by Liam Westley
    As I wasn’t voted in with my nominated sessions I presented a 20/20 talk on the new async functionality coming with the .Net Framework.  This was based on the PechaKucha presentation format, where you have only 20 slides with only 20 seconds per slide, and it progresses automatically. It was the first I’d attempted, so thanks to the organisers for allowing me to have a go. Although creating the slide deck was definitely easier than a one hour presentation, it was much more stressful giving the talk by the end of the 6m 40s. I’m not going to upload the slide deck (it won’t make much sense) but I did record the audio and used the excellent Camtasia to create a video of the slide deck with that audio which you can watch over here, https://vimeo.com/42957952

  • Using glReadBuffer returns black image instead of the actual image only on Intel cards

    - by cloudraven
    I have this piece of code glReadBuffer( GL_FRONT ); glReadPixels( 0, 0, width, height, GL_RGB, GL_UNSIGNED_BYTE, buffer ); Which works just perfectly in all the Nvidia and AMD GPUs I have tried, but it fails in almost every single Intel built-in video that I have tried. It actually works in a very old 945GME, but fails in all the others. Instead of getting a screenshot I am actually getting a black screen. If it helps, I am working with the Doom3 Engine, and that code is derived from the built-in screen capture code. By the way, even with the original game I cannot do screen capture on those intel devices anyway. My guess is that they are not implementing the standard correctly or something. Is there a workaround for this?

  • CRM Goes to School, Supports Enrollment Growth

    - by Tony Berk
    At Post University in Waterbury, CT, the focus is on the student. Generally, the first interaction from a potential student is a lead, which can come from a variety of sources. Any delay in following up with the interested student (the lead) affects the conversion success rate, i.e., the likelihood of enrollment. By implementing Oracle CRM On Demand, Post University automated the admissions process so the admissions counselors are in direct contact with the students and eliminated many manual steps. The admissions and marketing teams, as well as the students, benefit from the new streamlined process. Up next, Post University, plans to increase the efficiency of the student retention processes with the expansion of Oracle CRM On Demand. Take a look at the video to learn more about Post University's Oracle CRM On Demand implementation: Congrats to Post University, and Apex IT, their implementation partner, on the successful implementation!

  • How to make Pokémon White 3D effect?

    - by Pipo
    I just wondered how to create a 3D effect similar to Pokemon White/Black? It seems to be not polygon based, but created just with sprites. If the perspective changes the sprites stay sharp and don't get blurred. How can I archive this? Source: https://www.youtube.com/watch?v=fZEPUPYOnRc&feature=youtube_gdata_player Edit: Wow, two downvotes because I used a video instead of screenshots? Don't get me wrong, I thank you, because you want to help me, but the 3D effect can be better understand in motion. Anyway, here is a screenshot: http://wearearcade.com/wp-content/uploads/2011/03/pokemon-black-white-starter-town.jpg So, if this is a hardware limitation, how can I archive this o na different hardware, e.g. a HTML5 game? Thank you.

  • Can I animate render targets or the swap chain?

    - by Eric F.
    I want to animate some synthetic video bits to fullscreen w/o tearing. Can I set up D3D 9/10/11 in exclusive mode, and have it present a series of buffers that I'm writing to? I know how to copy system memory bits into a texture, then draw that texture as a fullscreen quad, but it seems like overkill. Why should I use the triangle rasterizer when I want to do something so simple? All I want to do is set up a long (4-8 buffer) swapchain and set the bits of the back buffer that is about to be displayed. Or, I want to allocate 4-8 RenderTargets, and on each frame, copy the bits from system memory to the RenderTarget, then set it as the next thing to display. I've never seen or heard about anybody doing this, but it seems so dead simple!
