  • APress Deal of the Day 15/Jan/2011 - Windows Mobile Game Development: Building games for the Windows Phone and other mobile devices

    - by TATWORTH
    Todays Apress $10 deal of the the day is: Windows Mobile Game Development: Building games for the Windows Phone and other mobile devices This book will provide you with a comprehensive guide to developing games for both the Windows Mobile platform and the Windows Phone using the industry standard programming languages C# and VB.NET. $49.99 | Published Apr 2010 | The book dates from the VS2005/VS2008 era but should still be useful to VS2010 developers. Given that such games development can now be done within Visual Studio. Whilst these devices use the Compact Framework instead of the standard Dot Net Framework, it is still a familiar envirnment. This book should be of benefit not just to games developers but to anyone with an interest in development for mobile phones.

  • Make public webcam. Which protocol, which codec. (Using VLC)

    - by gsedej
    Hi! I want to use my old (1GHz) PC as webcam video stream server (like you can see those road cameras). I thought of using VLC and already tried using http output but it was not really good. Too cpu hungry, too big stream (kBps), not stable... I been reading VLC how-to's but thre is still a question. Which output should I use? Http, RTSP, UDP? I want to make for more than one computer at the same time (multicast). Which codec should be good? PC is not so fast so it shouldn't be too cpu hungry codec. Mpeg2, mpeg4, xvid? how much video buffer should I use (vb=?)? What about setting IP and ports? So I need some help with ideas, but if someone can make a VLC command line it's even better :) Oh, computer has direct internet connection and own IP.

  • ideas on multiplayer games which include lots of collaboration?

    - by user494461
    For my master thesis I wanted to design a small multiplayer game which includes more than one player(maybe 5), has 2-3 players collaborating at a time to achieve some task. The most important thing is realistic simulation of the movable objects in the scene which more than one player should simultaneously interact with. I would also prefer large virtual environments (VEs) like mmogs where groups of players are interacting in different areas of the VE. tasks for players should include 2-3 players touching movable objects at same time. e,g, a very basic task can be users lifting a cube together and pushing it through a hole I am not new to designing virtual environments with openGL, but have never designed games before and rarely play other than few of my favorite ones like Fifa. I wanted some ideas on what kind of games should I look at which should help me with ideas for my tasks for the users to gain points and win in games? any current indie games which might inspire me?

  • Ubuntu 12.04 video issue on Dell Inspiron 1100

    - by Edwould
    I have an old clunker - Dell Inspiron 1100 with A32 BIOS. I managed to install correctly from a USB drive, and the screen showed graphics in full natice 1024 x 768 - as did the 'try from USB' Ubuntu option. Once I committed to a full install on the HDD, the video resolution comes up as 640 x 480 with no other resolutions to change to full screen. Does anyone have some advice to allow the full LCD panel to be used? Thanks for reading Ed

  • Convert video files for home IIS server [closed]

    - by Jey
    I am finally learning to set up an IIS server (personal use only) and I thought it would be cool to have some videos on it for me to watch when I am away from home. Since I'm usually on 3G (iPhone) or work wifi, I'd like to convert them to an optimal format that will stream fast. The video files are mostly avi and mp4 (from 30 minutes to 2 hours in length). What would be an easy and fast way to go about doing this? Thanks.

  • Video: A Peek Inside the HTC Incredible Phone

    <b>Wired: </b>"TechRestore, an electronics repair shop, has taken apart the Incredible and then it put all back together. What's fascinating to watch in the video is how small and compact the components are and how well they pack into the circuit board."

  • Videos stutter in full screen

    - by user85256
    Using Ubuntu 12.04 with Gnome 3.4.2. When I load video files (avi, mkv, mp4), they play smoothly in windowed mode, but when in full screen, they mildly (but noticeably) stutter. I've tried various players (from VLC to SMplayer2), with many different output drivers and it's always the same. Also, my video card is AMD Radeon HD 6450, and I've had no luck with the proprietary FGLRX drivers. Every time I install them, my system becomes very sluggish (window dragging animations become choppy etc.). Thanks in advance, guys.

  • MediaElement.js setSrc() Loading The File But Not Changing pluginType

    - by doubleJ
    I'm working on a page that uses mediaelement.js to play mp3/mp4/wmv (yes, we have a lot of wmv). I have a list of links and those links should change the player. My effort is to make the changes to the player through javascript so that the page doesn't refresh. This code is working, but it refreshes every time. See a live demo of the non-ajax version. <?php $file = null; $file = $_GET["file"]; $format = null; if (preg_match("/mp4/i", $file)) $format = "mp4"; if (preg_match("/webm/i", $file)) $format = "webm"; if (preg_match("/wmv/i", $file)) $format = "wmv"; if (preg_match("/mp3/i", $file)) $format = "mp3"; if (preg_match("/ogg/i", $file)) $format = "ogg"; $mime = null; if ($format == "mp4") $mime = "video/mp4"; if ($format == "webm") $mime = "video/webm"; if ($format == "wmv") $mime = "video/wmv"; if ($format == "mp3") $mime = "audio/mp3"; if ($format == "ogg") $mime = "audio/ogg"; $element = "video"; if ($format == "mp3" || $format == "ogg") $element = "audio"; // you have to escape (\) the escape (\) character (hehehe...) $poster = "media\\120701Video.jpg"; $height = "360"; if ($format == "mp3") $height = "30"; ?> <!doctype html> <html> <head> <meta charset="utf-8"> <title>Embed</title> <link rel="stylesheet" href="include/johndyer-mediaelement-b090320/build/mediaelementplayer.min.css"> <style> audio {width:640px; height:30px;} video {width:640px; height:360px;} </style> <script src="include/johndyer-mediaelement-b090320/build/jquery.js"></script> <script src="include/johndyer-mediaelement-b090320/build/mediaelement-and-player.js"></script> </head> <body> <ul> <li><a href="embed.php">Reset</a></li> <li><a href="?file=media/120701Video-AnyVideoConverter.mp4">Alternative (mp4)</a></li> <li><a href="?file=media/120701Video-Ffmpeg-Defaults.webm">Alternative (webm)</a></li> <li><a href="?file=media/AreYouHurting-Death.wmv">Alternative (wmv)</a><li> <li><a href="?file=media/AreYouHurting-Death.mp3">Alternative (mp3)</a></li> </ul> <?php if ($file) { ?> <video src="<?php echo $file; ?>" controls poster="<?php echo $poster; ?>" width="640" height="360"></video> <div id="type"></div> <script> var video = document.getElementsByTagName("video")[0]; var player = new MediaElementPlayer(video, { success: function(player) { $('#type').html(player.pluginType); } }); <?php } ?> </script> </body> </html> This code requires <video> to be loaded, initially and with a file, so that the player mode (pluginType) is set. It will, then, only play formats that the pre-established mode supports (firefox in native mode won't play mp4). See a live demo of the ajax version. <!doctype html> <html> <head> <meta charset="utf-8"> <title>Embed</title> <link rel="stylesheet" href="http://www.mediaelementjs.com/js/mejs-2.9.2/mediaelementplayer.min.css"> <script src="//ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script> <script src="http://www.mediaelementjs.com/js/mejs-2.9.2/mediaelement-and-player.js"></script> </head> <body> <ul> <li><a href="javascript:player.pause(); player.setSrc('media/120701Video-AnyVideoConverter.mp4'); player.load(); player.play();">Alternative (mp4)</a></li> <li><a href="javascript:player.pause(); player.setSrc('media/120701Video-Ffmpeg-Defaults.webm'); player.load(); player.play();">Alternative (webm)</a></li> <li><a href="javascript:player.pause(); player.setSrc('media/AreYouHurting-Death.wmv'); player.load(); player.play();">Alternative (wmv)</a></li> <li><a href="javascript:player.pause(); player.setSrc('media/AreYouHurting-Death.mp3'); player.load(); player.play();">Alternative (mp3)</a></li> </ul> <video controls src="media/WordProductionCenter.mp4"></video> <div id="type"></div> <script> var video = document.getElementsByTagName("video")[0]; var player = new MediaElementPlayer(video, { success: function(player) { $('#type').html(player.pluginType); } }); </script> </body> </html> It seems like I need something like setType(), but I see no such option. I've read a couple pages that referenced refreshing the DOM after the javascript runs, but I haven't been able to successfully do it (I know enough about javascript to hack things around and get stuff working, but not enough to create whole new things). It is worth noting that Silverlight doesn't work with Internet Explorer 8 or Safari (not sure if it's my code, mejs, or the browsers). Also, neither Silverlight nor Flash play mp3 or webm (again, not sure where the problem lies). Is there a way to dynamically load different types of files into mediaelement?

  • How can you save Cocos2D window output as Video?

    - by crunchyt
    I am considering using the excellent looking Cocos2d for a motion graphics project. However, Cocos2d is intended for games, rather than producing an MPEG stream. Is it possible to save the output from a Cocos2d script to a MOV or MPG file? Ideally this needs to be done in a direct manner, not using a screen capture as this would not meet the requirements of the project. Hopefully there are some cocos2d gurus out there :D Thanks!

  • Detect NetStream events with AS3 Video Object (not component)

    - by JFOX
    I have created a FLV video player using the AS3 flash.media.Video object (not the FLV playback component) and I am trying to listen for meta events and Cue Points embedded in the FLV video but I am not receiving any when I trace the movie. The cue points are not being created dynamically, they are in the FLV video. Video embed code: // Initialize net stream nc = new NetConnection(); nc.connect (null); // Not using a media server. ns = new NetStream(nc); // Add video to stage vid = new Video(456,675); addChild (vid); // Add callback method for listening on // NetStream meta data client = new Object(); ns.client = client; client.onMetaData = this.nsMetaDataCallback; client.onCuePoint = this.onCuePoint; // Play video vid.attachNetStream ( ns ); ns.play ("flv/00_010.flv"); callback handlers in the same class as the above code: public function onCuePoint(info:Object):void { trace("cuePoint: time = " + info.time + " name = " + info.name + " type = " + info.type); if (ns) ns.pause(); } public function nsMetaDataCallback (mdata:Object):void { trace (mdata.duration); } Is there anything I am missing have wrong to capture events from my net stream?

Below is the code of my title activity. public class Title extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); setContentView(R.layout.title); setTitle("M.I.S.T"); this.setTitleColor(Color.BLUE); View title = getWindow().findViewById(android.R.id.title); View titleBar = (View) title.getParent(); titleBar.setBackgroundColor(Color.YELLOW); Thread timer = new Thread(){ public void run(){ try{ sleep(3000); }catch (InterruptedException e){ e.printStackTrace(); }finally{ Intent open= new Intent("com.congestion6.asad.MENU"); startActivity(open); } } }; timer.start(); } protected void onPause() { // TODO Auto-generated method stub super.onPause(); finish(); } }

  • Force windows video driver reload. Is it possible at all?

    - by somemorebytes
    Hi there, Some drivers use parameters written in the registry to configure themselves when they get loaded at boot time. I can modify those values and then reboot, but I would like to know if it is possible to force the driver reload, making the changes effective without rebooting. Specifically, I am talking about the video driver (nvidia). I read somewhere, that calling through pINvoke() [User32.ll]::ChangeDisplaySettings() with a 640x480x8bits resolution,(which is so low that it should not be supported by a modern driver) will force windows to load the "Standard VGA driver", and making another call with the current resolution will load the nvidia driver again. This does not work though. At least in Windows 7, even if the low res is not displayed as "supported" the system reduces the screen to a little square in the center of the screen, showing the low res wihtout unloading the nvidia driver. So, is there any .NET/Win32 API, service to restart, or any way at all to force a video driver reload? Perhaps programatically disabling the device (as you could do from the Device Manager) and reenabling it again? Any idea? Thanks a lot.
