  • What technologies allow bidirectional streaming of video?

    - by Roman
    Wikipedia says that Flash allows "bidirectional streaming of audio and video". Is it possible to do that with other technologies (for example with JavaScript)? In other words, I want to transfer video from one user of web-site to another one in real time. I want to have something that is already installed by many users or easy to install (Flash fulfills this requirements). And I want to have something free.

  • Explaining odd sound effects during BSOD

    - by bizzz
    Hello, over the years of using Microsoft operating systems, I many times encountered the situation that I only now want to understand. When you get BSOD while listening to music, there is a short period of time (1-2 sec), when screen freezes and the last part of music is repeated several times, before everything falls into blue abyss. Today I became very curious about mechanics behind this situation - what makes that certain part of audio to loop? I beg you, kind sirs, to satisfy my curiosity.

  • How to install missing Sound Drivers in Ubuntu?

    - by Sakamoto Kazuma
    I seem to be missing drivers for my Gateway laptop MA7. I have looked in System-Admin-Hardware Drivers, but it does not show up in there.There are also no devices listed in Sound-Hardware. I'm guessing at this point that I don't have the driver installed. However, I get the following output: admin@machine001:~$ cat /proc/asound/cards 0 [Intel ]: HDA-Intel - HDA Intel HDA Intel at 0xd8240000 irq 22 admin@machine001:~$ And my lspci shows: 00:00.0 Host bridge: Intel Corporation Mobile 945GM/PM/GMS, 943/940GML and 945GT Express Memory Controller Hub (rev 03) 00:02.0 VGA compatible controller: Intel Corporation Mobile 945GM/GMS, 943/940GML Express Integrated Graphics Controller (rev 03) 00:02.1 Display controller: Intel Corporation Mobile 945GM/GMS/GME, 943/940GML Express Integrated Graphics Controller (rev 03) 00:1b.0 Audio device: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 02) 00:1c.0 PCI bridge: Intel Corporation 82801G (ICH7 Family) PCI Express Port 1 (rev 02) 00:1c.1 PCI bridge: Intel Corporation 82801G (ICH7 Family) PCI Express Port 2 (rev 02) 00:1d.0 USB Controller: Intel Corporation 82801G (ICH7 Family) USB UHCI Controller #1 (rev 02) 00:1d.1 USB Controller: Intel Corporation 82801G (ICH7 Family) USB UHCI Controller #2 (rev 02) 00:1d.2 USB Controller: Intel Corporation 82801G (ICH7 Family) USB UHCI Controller #3 (rev 02) 00:1d.3 USB Controller: Intel Corporation 82801G (ICH7 Family) USB UHCI Controller #4 (rev 02) 00:1d.7 USB Controller: Intel Corporation 82801G (ICH7 Family) USB2 EHCI Controller (rev 02) 00:1e.0 PCI bridge: Intel Corporation 82801 Mobile PCI Bridge (rev e2) 00:1f.0 ISA bridge: Intel Corporation 82801GBM (ICH7-M) LPC Interface Bridge (rev 02) 00:1f.1 IDE interface: Intel Corporation 82801G (ICH7 Family) IDE Controller (rev 02) 00:1f.2 SATA controller: Intel Corporation 82801GBM/GHM (ICH7 Family) SATA AHCI Controller (rev 02) 00:1f.3 SMBus: Intel Corporation 82801G (ICH7 Family) SMBus Controller (rev 02) 02:00.0 Ethernet controller: Marvell Technology Group Ltd. 88E8038 PCI-E Fast Ethernet Controller (rev 14) 03:00.0 Network controller: Intel Corporation PRO/Wireless 3945ABG [Golan] Network Connection (rev 02) 04:09.0 CardBus bridge: Texas Instruments PCIxx12 Cardbus Controller 04:09.1 FireWire (IEEE 1394): Texas Instruments PCIxx12 OHCI Compliant IEEE 1394 Host Controller 04:09.2 Mass storage controller: Texas Instruments 5-in-1 Multimedia Card Reader (SD/MMC/MS/MS PRO/xD) I have also checked alsamixer, and nothing is muted.

  • Windows: How to load and save sound schemes?

    - by Ashwin
    Windows users can change the sounds associated with program events using the dialog in Control Panel - Sound and Audio Properties - Sounds. Different sounds (or no sound) can be assigned to program events and the sound scheme can be saved. Where and how does Windows store its sound schemes? How do I export or save this sound scheme and load it somewhere else? (I am using Windows XP.)

  • How to enjoy DVD on Apple iPad

    - by user44251
    I believe many people spent a sleepless night yesterday waiting for the new Apple Tablet to come, just a few days ago or perhaps longer I noticed fierce debate about it, its name, size, capacity, processor, main features, price etc. And now, they can take a long breath with the new Apple Tablet named iPad officially released on 28, January, 2010 (Beijing Time). But I know a new battle just begins. iPad, sounds somewhat like iPod and it really shares some similarities in terms of shape like smart, light and portable. It has a 9.7-inch, LED-backlit, IPS display with a remarkable precise Multi-Touch screen. And yet, at just 1.5 lbs and 0.5 inches thin, it's easy to carry and use everywhere. It can greatly facilitates your experience with the web, emails, photos and videos. Right now, it can run almost 140.000 of the apps on the Apple store. It can even run the apps you have downloaded for your iPhone or iPod touch. But so far, I haven't seen any possibility that it can work with DVD, probability there is no built-in DVD-ROM or DVD player which can play DVD directly. As Apple iPad states, the video formats supported are MPEG-4 (MP4, M4V), H.264, MOV etc and audio formats accepted are AAC, Proteceted AAC, MP3, AIFF and WAV etc, those are formats that are commonly used with iMac. This could really a hard nut to crack if you want to watch your favourite DVD on this magic Apple iPad. But don't worry, there is still way out, you just need a few steps for ripping and importing DVD movies to Apple iPad with a simple application DVD to iPad converter What's on DVD to iPad Converter for Mac DVD to iPad converter for Mac is a powerful and professional application designed for the newly released Apple iPad which can rip, convert your DVD contents to Apple iPad compatible MPEG-4 (MP4, M4V), H.264, MOV etc, and other popular file formats like AVI, WMV, MPG, MKV, VOB, 3GP, FLV etc can also be converted so that you can put on your portable devices like iPod, iPhone, iRiver, BlackBerry etc. Besides, it can also extract audio from DVD videos and save as MP3, AIFF, AAC, WAV etc. Mac DVD to iPad converter has also been enhanced that can run both on PowerPC and Intel (Snow Leopard included). It can offer versatile editing features which allows you to make your own DVD videos. For example, you can cut your DVD to whatever length you like by Trim, crop off unwanted parts from DVD clips by Crop, add special effect like Gray, Emboss and Old film to make your videos more artistic. Besides, its built-in merging feature and batch mode allows you to join several DVD clips into a single one and do batch conversion. And more features can be expected if you afford a few minutes to try.

  • Firefox 16 freezes or crashes when playing Youtube or flash videos

    - by Matt
    Using the most up to date Firefox (16.0.2), and Adobe Flash. Whenever I go to any youtube video or flash video on another page, Firefox starts the video, but only plays the audio, and then when I make any click on anywhere within Firefox, it gets completely stuck. It freezes and the only way to get it to close is to go to task manager. I restarted in Safe Mode and it did the same thing. Windows 7 64 bit.

  • bigbluebutton or openmeetings?

    - by Adam Monsen
    I want to set up a server for small group meetings. I'm looking for features like audio conferencing, multi-point video, screen sharing... stuff like that. I'm familiar/comfortable administering Ubuntu servers, so for this task I'd likely fire up a small EC2 server running Ubuntu. I'm most interested in using FLOSS. I see there are at least a couple of options out there. For example: bigbluebutton and openmeetings. Anyone installed either (or a different one) and have recommendations/tips? If yes, have you ever upgraded same? I notice bigbluebutton has deb packages, so that might be pretty straightforward. openmeetings appears to support logging in with a facebook account; that might be a good way to avoid having to manage logins.

  • Best software to convert video to a different aspect ratio for various screensizes

    - by facepalmd
    I sometimes get .mp4 and other video formats whose aspect ratio is clearly off What apps do you use to reconvert such videos to an aspect ratio better suited to to fit either a regular desktop or LCD screen size? Hopefully with little or no loss of audio/video quality Any instructions on best settings to use would be very welcome. I have so far mostly used vlc which came off with less-than-ideal results. Thanks for any help you can offer.

  • What is the best method for ripping DVD to stream to Xbox 360?

    - by Dan9298
    What is the best method to rip/encode a standard definition DVD, to be streamed to a Xbox360 from a Vista Media Center pc (preferably using free software). I’ve found tons of tutorials on the web explaining how to create wmv’s from vob files using FFMpeg, but every combination of settings that I have tried has resulted in very poor video quality. I’ve also tried various video conmversion tools, but everything seems to result in poor video quality, or audio that is out of sync with the picture. Please help!

    - by smwikipedia
    I try to install a small audio player named "Audacious" with the following command: sudo apt-get install audacious and it tells me that it depends audacious-plugins, so I try to install the audacious-plugins, one thing leads to another, there're numerous depends and it is just impossible to install all of them manually... Is it even possible to install a software on ubuntu linux? Is there a way to auto install all the depends? (I have never seen such a stupid software manager.) Many thanks.

  • Windows Media Player 11 doesn't download codecs for avi files

    - by ChrisF
    I've got some avi files that WMP will play the audio for but not the video. Why doesn't WMP download the codecs it needs? Or is the solution to download a codec pack and install that manually? In "Options Player" the "Download codecs automatically" option is checked. I've installed VLC so I can watch them, which I'm quite happy about so I don't need a recommendation for a new player.

  • Always route a keypress to an application regardless of focus

    - by George Mauer
    I have to transcribe some audio (not enough to download dedicated software but enough to put my hacker hat on) and flipping back and forth between vlc and my text editor every time I want to pause is really annoying. Is there a way to always route a key-press (for example F10) to vlc regardless of what window has focus. Bonus - I have a Makey Makey so if I can get this working I can create a pedal and it will be my first real use of it!

  • Is it possible to run several virtual machines each with independent mouse+keyboard on a single PC?

    - by chiurox
    My goal is to instead of buying 4 separate basic PCs (plus the obvious peripherals), buy just one fast PC and the peripherals. I'm wondering if I can use a more powerful computer, say, one with core i7 and plenty of RAM, with 2 video cards (total of 4 monitor outputs) to run 4 or more virtual machines (WinXPs) so instead of having 4 individual machines, I'll be having just one. However, the catch is, is it possible to have a pair of mouse and keyboard + input/output audio for each of these virtual machines?
