    - by shubhkarman
    Hello, I am developing a new Java Desktop app. Something like a media player. I want to load most of the resources in the background when the computer starts up. But the users can turn this option off form within the app or using some other utility. So, what I want to do is if a ban instance of the app is already running and the user starts the app again then I can communicate with the already running instance so that it can launch a new window?

  • .NET Network Library

    - by Mark
    I've been looking for a decent network library for C#. It is going to be used with XNA 3.1, and .NET Framework 3.5. The multi-player style is going to be Server and Client. Currently I have been looking into Lidgren Library Network, but it seems outdated. Anyone got some good suggestions for a good network library. It should be able to handle easily 30+ client connections at a time.

Separately to that I have used Joomla to create websites for small businesses. I'd like to be able to use Joomla as my online application development environment. Is there a way I can use Joomla for that?

  • How to bridge Debian guest VM to VPN via Cisco AnyConnect Client running on Windows Vista host

    - by bgoodr
    I am running Cisco Anyconnect VPN Client version 2.5.3054 on a laptop running Windows Vista Home Premium (version 6.0.6002) Service Pack 2. I am running the VMware Player version 4.0.2 build-591240. The host operating system running under VMware Player is Debian 6.0.2.1 i386. The laptop is connected to a wireless connection, and I can browse the web from Windows Vista using Firefox just fine. I am able to boot into the Debian VM and open up a browser and access websites on the WAN from within the VM just fine. I can ping real Linux hosts on my LAN via: ping <lan_system>.local where <lan_system> is the hostname returned from uname -a on that system on my LAN. From a DOS CMD shell, I am able to ping hosts that exist on the remote network served by the Cisco AnyConnect Client's VPN network (and without the .local suffix applied as above): ping <remote_system> However, from within the Debian VM, I expect to be able to also ping those same remote hosts (<remote_system>) that are tunnelled over the VPN set up by Cisco AnyConnect Client. Let's say that I can ping a <remote_system> called flubber from a DOS CMD prompt just fine. When I execute Linux ping command from inside the Debian VM via: ping flubber It returns immediately with this output: ping: unknown host flubber For reference since I suspect it will be useful, here is the output of the route print command from the DOS CMD prompt: route print =========================================================================== Interface List 30 ...00 05 9a 3c 7a 00 ......

  • Chrome does not re-draw properly on Windows 8

    - by Akshat Mittal
    There are a lot of problems with Chrome (24.0.1312.14 beta || But all this happened before update also) on Windows 8. Problems and explanations are listed below: Google Chrome re-draw time: When I switch tabs, the window retains the content of the previous tab and displays that even if I move my mouse, if only refreshes (re-draws) when there is a change on the webpage (like on hover) or I do a select all (or scroll). One thing to note is that the hover and select happens on the real page and not the retained image-like thing of the older webpage. Chrome is slow and laggy: Websites such as Facebook and Twitter (and more) have gone extremely laggy on Chrome (Win 8). When I was using Windows 7, I never experienced a lag or something. Also when using HTML-5 Websites, the transition (the -webkit-transition in CSS) goes extremely slow at times. Plugins Crash: Plugins like Flash Player, Shockwave Player, and more that are in-built into Chrome Crashes a lot, even when doing simple tasks like playing YouTube Videos, displaying ads or something. Chrome Crashes: Chrome has crashed over 100 times in the past month. Google Chrome just crashes randomly or I don't know the reason. Random Page crashes: Chrome results chrome://crash/(Copy-Paste this in address bar) on random pages even when the page is just loaded, I understand that this can happen on heavy HTML5 or JS websites but what about HTML only websites? Computer Freeze: Chrome sometimes, randomly, freezes my computer. Freeze in the sense, none of the other apps are also working. It's like the whole system freezes, I can not even switch to other apps. I am sure that this is because of Chrome since this happens only when Chrome is active. Most of the things above happens on Super User also, Super User never had any problem when using Chrome on Windows 7. UPDATE 1: @magicandre1981 Commented for trying to disable Hardware Acceleration. I tried it, it somewhat solved the problem but din't fix it. I am still experiencing all the above issues but less frequently (maybe because Chrome Restarted Completely) UPDATE 2: @avirk asked me to try a Stable Version of Chrome and Firefox, I din't experience any lag in Firefox, a little (negligible) lag in Chrome 22 (Maybe because its a new copy of Chrome, I haven't used it much). UPDATE 3: @NothingsImpossible said that He is also experiencing the same problem on Windows Server 2008! This seams to be a major issue now. He also said that GPU load is also high at the same time! Even I saw the same thing. UPDATE 4: Recently, Chrome updated to v24 Stable (I am using stable from a long time now). I was experiencing this problem a lot less in Chrome 23, but this is back in Chrome 24. Seams like Chrome 24 is the most affected from this bug, as this same problem was high in Chrome 24 beta also. UPDATE 5: Chrome was updated to v25 Stable. This problem is 99% Gone, it is still there in 1% of the cases. One such example is when I leave chrome inactive for a while with a few tabs open, the tabs go black and no activity can get them back to active state. If I open a new tab, the new tab is OK but the others are still black, I need to close all those tabs. UPDATE 6: Chrome updated to v27 Stable channel, this problem is nearly gone. This does happen occasionally, but not as frequent as in earlier versions of Chrome. UPDATE 7: I am on Chrome v35.0.1916.114 Stable, Windows 8.1 Pro Update 1. Some of the other problems appears to be back. Chrome is slow and laggy again. Re-draw time is getting worse. Is anybody else experiencing such issues? Does anybody have a solution to any of these?

  • Use DivX settings to encode to mp4 with ffmpeg

    - by sjngm
    I'm used to use VirtualDub to encode a video to AVI container with DivX-codec (and MP3 for audio). Now I'm planning to use ffmpeg to encode videos to MP4 container with h264-codec. What I've figured out is that I need to use libx264 and one of those presets to make anything work. However, I'm amazed about the video bitrate ffmpeg uses for encoding. What I currently have is this little batch file: @ECHO OFF SETLOCAL SET IN=source.avs SET FFMPEG_PATH=C:\Program Files (x86)\ffmpeg SET PRESET=-fpre "%FFMPEG_PATH%\presets\libx264-lossless_slow.ffpreset" SET AUDIO=-acodec libmp3lame -ab 128000 SET VIDEO=-vcodec libx264 -vb 1978000 "%FFMPEG_PATH%\ffmpeg.exe" -i %IN% %AUDIO% %VIDEO% %PRESET% test.mp4 ENDLOCAL With this I tell ffmpeg to use 1978k as the bitrate, but ffmpeg uses 15000k+! I tried other presets, but they don't use my specified bitrate. Here are the presets I have: libx264-baseline.ffpreset libx264-ipod320.ffpreset libx264-ipod640.ffpreset libx264-lossless_fast.ffpreset libx264-lossless_max.ffpreset libx264-lossless_medium.ffpreset libx264-lossless_slow.ffpreset libx264-lossless_slower.ffpreset libx264-lossless_ultrafast.ffpreset ffmpeg version: FFmpeg git-N-29181-ga304071 libavutil 50. 40. 1 / 50. 40. 1 libavcodec 52.120. 0 / 52.120. 0 libavformat 52.108. 0 / 52.108. 0 libavdevice 52. 4. 0 / 52. 4. 0 libavfilter 1. 79. 0 / 1. 79. 0 libswscale 0. 13. 0 / 0. 13. 0 Note that I don't use the latest version as it has problems with spaces in filenames. Here's what seems to be the full parameter list DivX 6.9.2 uses: -bvnn 1978000 -vbv 218691200,100663296,100663296 -dir "C:\Users\sjngm\AppData\Roaming\DivX\DivX Codec" -w -b 1 -use_presets=1 -preset=10 -windowed_fullsearch=2 -thread_delay=1 What command line parameters would that be for ffmpeg? EDIT: Going with slhck's suggestion I tried a new 32-bit version. I have no idea if that is 0.9 or newer, I can't find that info. ffmpeg version N-36890-g67f5650 libavutil 51. 34.100 / 51. 34.100 libavcodec 53. 56.105 / 53. 56.105 libavformat 53. 30.100 / 53. 30.100 libavdevice 53. 4.100 / 53. 4.100 libavfilter 2. 59.100 / 2. 59.100 libswscale 2. 1.100 / 2. 1.100 libswresample 0. 6.100 / 0. 6.100 libpostproc 51. 2.100 / 51. 2.100 I reworked my batch file to look like this (interestingly enough I can't find parameter -vprofile in the documentation): @ECHO OFF SETLOCAL SET IN=VTS_01_1.avs SET FFMPEG_PATH=C:\Program Files (x86)\ffmpeg SET PRESET=-vprofile high -preset veryslow SET AUDIO=-acodec libmp3lame -ab 128000 SET VIDEO=-vcodec libx264 -vb 1978000 "%FFMPEG_PATH%\ffmpeg.exe" -i %IN% %AUDIO% %PRESET% %VIDEO% test.mp4 ENDLOCAL I see that it now uses the bitrate properly (thanks to LongNeckbeard for pointing out that the lossless-stuff ignores the bitrate!). Just in case you wonder how I came up with the 1978000, I'm using this formula which I found valid for DivX-files (I'm guessing the bitrate won't change that much for h264): width * height * 25 * 0.22 / 1000 I'm not sure if the 0.22 correlates with the CRF somehow. Overall I forgot to say the I will use a two-pass scenario, which is why I don't use the CRF here. I will try to read more about this. Currently I'm just trying to get something running that shows me that I'm doing something right (ffmpeg isn't the easiest tool to understand ;)).

  • Command-line video editing in Linux (cut, join and preview)

    I have rather simple editing needs - I need to cut up some videos, maybe insert some PNGs in between them, and join these videos (don't need transitions, effects, etc.). Basically, pitivi would do what I want - except, I use 640x480 30 fps AVI's from a camera, and as soon as I put in over a couple of minutes of that kind of material, pitivi starts freezing on preview, and thus becomes unusable. So, I started looking for a command line tool for Linux; I guess only ffmpeg (command line - Using ffmpeg to cut up video - Super User) and mplayer (Sam - Edit video file with mencoder under linux) are so far candidates, but I cannot find examples of the use I have in mind.   Basically, I'd imagine there's an encoder and player tools (like ffmpeg vs ffplay; or mencoder vs mplayer) - such that, to begin with, the edit sequence could be specified directly on the command line, preferably with frame resolution - a pseudocode would look like: videnctool -compose --file=vid1.avi --start=00:00:30:12 --end=00:01:45:00 --file=vid2.avi --start=00:05:00:00 --end=00:07:12:25 --file=mypicture.png --duration=00:00:02:00 --file=vid3.avi --start=00:02:00:00 --end=00:02:45:10 --output=editedvid.avi ... or, it could have a "playlist" text file, like: vid1.avi 00:00:30:12 00:01:45:00 vid2.avi 00:05:00:00 00:07:12:25 mypicture.png - 00:00:02:00 vid3.avi 00:02:00:00 00:02:45:10 ... so it could be called with videnctool -compose --playlist=playlist.txt --output=editedvid.avi The idea here would be that all of the videos are in the same format - allowing the tool to avoid transcoding, and just do a "raw copy" instead (as in mencoder's copy codec: "-oac copy -ovc copy") - or in lack of that, uncompressed audio/video would be OK (although it would eat a bit of space). In the case of the still image, the tool would use the encoding set by the video files.   The thing is, I can so far see that mencoder and ffmpeg can operate on individual files; e.g. cut a single section from a single file, or join files (mencoder also has Edit Decision Lists (EDL), which can be used to do frame-exact cutting - so you can define multiple cut regions, but it's again attributed to a single file). Which implies I have to work on cutting pieces first from individual files first (each of which would demand own temporary file on disk), and then joining them in a final video file. I would then imagine, that there is a corresponding player tool, which can read the same command line option format / playlist file as the encoding tool - except it will not generate an output file, but instead play the video; e.g. in pseudocode: vidplaytool --playlist=playlist.txt --start=00:01:14 --end=00:03:13 ... and, given there's enough memory, it would generate a low-res video preview in RAM, and play it back in a window, while offering some limited interaction ( like mplayer's keyboard shortcuts for play, pause, rewind, step frame). Of course, I'd imagine the start and end times to refer to the entire playlist, and include any file that may end up in that region in the playlist. Thus, the end result of all this would be: command line operation; no temporary files while doing the editing - and also no temporary files (nor transcoding) when rendering final output... which I myself think would be nice. So, while I think that all of the above may be a bit of a stretch - does there exist anything that would approximate the workflow described above?

  • Decoding AAC using MediaCodec API on Android

    - by Benjamin Reed
    I'm trying to used the MediaCodec API on Android to decode an AAC stream. (It's raw AAC.) I tried using the MediaFormat.createAudioFormat() to create the format object to pass to MediaCodec.configure(), but I kept getting errors when using AAC (audio/mp4a-latm). (It works with MP3 (audio/mpeg) though...) Finally I created a MediaExtractor for an AAC file and looked at the format object it was producing. I saw that it included the key "csd-0" for a ByteBuffer composed of two bytes both with the value 0x12. If I include that key and value in the format object that I used to configure the AAC codec, everything works. Does anyone have an idea what is going on? The documentation states that I shouldn't configure that key. Does anyone have a pointer to MediaCodec examples to decode AAC files without using MediaExtractor to generate the format object?

  • Bug with audio reCaptcha in safari

    - by George Crawford
    Hi all, Can other Safari users please test http://recaptcha.net/learnmore.html for me, to see if the audio reCaptcha plays properly? On my machine, I can only hear the audio if I click the Download sound as MP3 link. I also don't get the spoken introduction at all. It works OK in Firefox and Chrome. I was alerted to this bug on my own development site, using the Zend Service for ReCaptcha. However, if it's broken on the official site, then I guess it's not a Zend bug. There don't seem to be any JavaScript errors. Any ideas?

  • Has there ever been a great print version of Why’s Poignant Guide to Ruby?

    - by Paul D. Waite
    Although it’s probably meant to be experienced on the web, I’d love to read a great print version of Why’s Poignant Guide to Ruby. It’s liberally licensed, so I can run off a copy for myself. But I think a work like that deserves more. Full colour illustrations. Main text on the left-hand page, sidebars on the right. (Stick in a few cartoons, or a slice of onion, when there aren’t any sidebars.) A built-in MP3 player and headphones for the soundtrack, but made completely out of telephone wires. Whilst that might be wishing for too much, have you (ever) seen any decent print versions of the book available?

  • how to prevent MPMoviePlayer controls from hiding

    - by huevos de oro
    I am trying to implement a custom MPMoviePlayer to play mp3 audio. I have got it working in portrait mode along with an overlay window over the native controls - thanks to other stackoverflow posts. The current issue is the song progress control shows up when the media window opens (blue bar taking up the first 40 odd pixels), but seems to disappear when the song starts leaving a white bar. It will then re-appear when touching the area, so functionally works fine. I would like to find a way to ensure the controls always stay visible but have not found an appropriate property in the reference. Ideally I would like to have my custom control to replace the default, more because I would like to change the position that the look and feel. This being said, I understand it is not possible as the current position in the song from a MPMoviePlayer cannot be accessed.
