  • My OpenCL kernel is slower on faster hardware.. But why?

    - by matdumsa
    Hi folks, As I was finishing coding my project for a multicore programming class I came up upon something really weird I wanted to discuss with you. We were asked to create any program that would show significant improvement in being programmed for a multi-core platform. I’ve decided to try and code something on the GPU to try out OpenCL. I’ve chosen the matrix convolution problem since I’m quite familiar with it (I’ve parallelized it before with open_mpi with great speedup for large images). So here it is, I select a large GIF file (2.5 MB) [2816X2112] and I run the sequential version (original code) and I get an average of 15.3 seconds. I then run the new OpenCL version I just wrote on my MBP integrated GeForce 9400M and I get timings of 1.26s in average.. So far so good, it’s a speedup of 12X!! But now I go in my energy saver panel to turn on the “Graphic Performance Mode” That mode turns off the GeForce 9400M and turns on the Geforce 9600M GT my system has. Apple says this card is twice as fast as the integrated one. Guess what, my timing using the kick-ass graphic card are 3.2 seconds in average… My 9600M GT seems to be more than two times slower than the 9400M.. For those of you that are OpenCL inclined, I copy all data to remote buffers before starting, so the actual computation doesn’t require roundtrip to main ram. Also, I let OpenCL determine the optimal local-worksize as I’ve read they’ve done a pretty good implementation at figuring that parameter out.. Anyone has a clue? edit: full source code with makefiles here http://www.mathieusavard.info/convolution.zip cd gimage make cd ../clconvolute make put a large input.gif in clconvolute and run it to see results

  • Android always play intro clip

    - by mrmamon
    I'm trying to make my app to play intro clip for only when I start activities. But from my code it's always play the clip after wakeup before resume to app although I did not closed the app. What can I do to fix this prob? Thanks From main: startActivity(new Intent(this, MyIntro.class)); From MyIntro: public class MyIntro extends Activity implements OnCompletionListener { int a; @Override protected void onCreate(Bundle bundle) { super.onCreate(bundle); setContentView(R.layout.intro); playIntro(); } public void onConfigurationChanged(Configuration newConfig) { setContentView(R.layout.intro); } public void onCompletion(MediaPlayer arg0) { // TODO Auto-generated method stub this.finish(); } private void playIntro(){ setContentView(R.layout.intro); VideoView video = (VideoView) this.findViewById(R.id.VideoView01); Uri uri = Uri.parse("android.resource://real.app/" + R.raw.intro); video.setVideoURI(uri); video.requestFocus(); video.setOnCompletionListener(this); video.start(); } }

  • I have some questions about building an AIR app for use with a connected projector.

    - by knuckfubuck
    For an app I'm working on, I'd like to have a control panel window and a video output window to use for projecting video with an attached projector. I have built many Flash applications but this will be my first time using AIR so I have some questions. Is it possible to have two seperate windows as part of one AIR application? Can one of the windows (the video output) be in full-screen mode while the other window stays normal? How does AIR do with playing local video? Will there be crashes or choppy playback? Is there a better language option for what I'm trying to accomplish?

  • Is there a way to keep two videos synchronized in a webpage without plugins?

    - by Jared
    Is there a way to use two HTML5 video tags on a page and keep the videos synchronized? Meaning that if the first video is at 15.2 seconds then the second video is at 15.2 seconds? I've looked around and found SMIL but it looks like that only works in IE. I also tried to implement something of my own with jQuery and jMediaElement but there appears to be a lot of cases where the videos can get out of sync. Has this been done before?

  • Video desktop recording and multiple WM displays, capturing nonactive display

    - by okobaka
    Two WM running on one local machine. WM - Fluxbox. Using ffmpeg to record desktop. ffmpeg -an -f x11grab -s 1920x1080 -r 25 -i :1.0 -sameq /tmp/video.mkv On one display everything works great, but not when i have another WM display startx -- :1. What i am doing right now is to switch ctrl+alt+f8 to display:1.0, and start recording with ffmpeg. Everything is fine until i switch back ctrl+alt+f7 to display:0.0, WM and captured video image freezes, but when i switch back ctrl+alt+f8 to display:1.0, it unfreeze and continue recording. So, how to make display:1.0 not to freeze, while on display:0.0? Tested some more. open [display 0.0] open [display 0.1] from [display 0.0] = open => [display 0.2] same problem For different users and same users results are the same. ffmpeg keeps recording that paused image. Looks like WM root window need to be active, to be recorded.

  • Strange behaviour with mediaplayer and seekTo

    - by Mathias Lin
    I'm implementing a custom video player because I need custom video controls. I have an app with only one activity, which on startup shall start playing a video right away. Now, the problem I have is: I don't want the video to start from the beginning, but from a later position. Therefore I do a seekTo(16867). Since seekTo is asynchronous, I place the start call of the mediaplayer (player.start()) in the onSeekComplete of the onSeekCompleteListener. The strange behaviour I experience though is that I can see/hear the video playing from the beginning for a few millisecs before it actually plays from/jumps to the position I seeked to. But - on the other hand - the Log output I call before the player.start returns the correct position 16867, where I seeked to. Below is the relevant code section, the complete class is at http://pastebin.com/jqAAFsuX (I'm on Nexus One / 2.2 StageFright) private void playVideo(String url) { try { btnVideoPause.setEnabled(false); if (player==null) { player=new MediaPlayer(); player.setScreenOnWhilePlaying(true); } else { player.stop(); player.reset(); } url = "/sdcard/myapp/main/videos/main.mp4"; // <--- just for test purposes hardcoded here now player.setDataSource(url); player.setDisplay(holder); player.setAudioStreamType(AudioManager.STREAM_MUSIC); player.setOnCompletionListener(this); player.setOnPreparedListener(this); player.setOnSeekCompleteListener(new MediaPlayer.OnSeekCompleteListener() { public void onSeekComplete(MediaPlayer mediaPlayer) { Log.d("APP", "current pos... "+ player.getCurrentPosition() ); player.start(); // <------------------ start video on seek completed player.setOnSeekCompleteListener(null); } }); player.prepareAsync(); } catch (Throwable t) { Log.e(TAG, "Exception in btnVideoPause prep", t); } } public void onPrepared(MediaPlayer mediaplayer) { width=player.getVideoWidth(); height=player.getVideoHeight(); if (width!=0 && height!=0) { holder.setFixedSize(width, height); progressBar.setProgress(0); progressBar.setMax(player.getDuration()); player.seekTo(16867); // <------------------ seeking to position } btnVideoPause.setEnabled(true); }

  • mediaelement.js play/pause on click controls don't work

    - by iKode
    I need to play and pause the video player if any part of the video is clicked, so I implemented something like: $("#promoPlayer").click(function() { $("#promoPlayer").click(function() { if(this.paused){ this.play(); } else { this.pause(); } }); ...but now the controls of the video won't pause/play. You can see it in action here(http://175.107.134.113:8080/). The video is the second slide on the main carousel at the top. I suspect I'm now getting 2 onclick events one from my code above and a second on the actual pause/play button. I don't understand how the actual video controls work, because when I inspect the element, I just see a tag. If I could differentiate the controls, then perhaps I might have figured out a solution by now. Anyone know how I should have done this, or is my solution ok. If my solutions ok, how do I intercept a click on the control, so that I only have one click event to pause / play? If you look on the media element home page, they have a big play button, complete with mouseOver, but I can't see how they have done that? Can someone else help?

  • Windows Media Center showing Jerky Video on PC

    - by Kris Erickson
    I had to repave my Windows 7 x64 box last week due to a hard drive crash, and for a while everything was running perfectly but now all videos in Windows Media Center are jerky (the sound is fine, they just seem to skip a ton of frames all the time). This is on the local machine, but the same thing happens when I try to stream to my Xbox. The videos all show fine in VLC and Windows Media Player (however exhibit the same problem in Quicktime). I guess I must have installed something recently (in the process of getting all the apps I usually have running on my PC) that caused this but for the life of me I can't figure it out. I have updated to the latest video driver (and then rolled back to the standard Windows 7 driver), I have rolled back all the other drivers that I have installed (I believe). I have uninstalled all the codec packs (I also run TVersity, so I have the TVersity codec pack installed), and I uninstalled TVersity. Nothing seems to help. I have uninstalled windows media center, and reinstalled it from the Programs and Features. I have basically ran out of things to try to fix this, and am almost thinking about reinstalling Windows again. Any suggestions? Edit Specs on the PC (which I figured was unimportant since everything used to work perfectly): Intel Core 2 CPU 6600 @ 2.4 Ghz Nvidia GTS 8800 Built in realtek-audio soundcard 4GB Ram Codecs which are failing: All that I have tried, but at least Xvid, Mpgv (mpeg2 video from a camera), and Wmv (only kinds that I have ready access to).

However, any hyperlinked content that appears above or below the video is unclickable, as the video takes the focus on the iPad. This isn't a problem with Safari in general, as it works on Desktop Safari. Thankyou, BH

    I want to get the number of frames from a video. I'm using the following code: package com.vidualtest; import java.io.File; import java.io.FileDescriptor; import android.app.Activity; import android.graphics.Bitmap; import android.media.MediaMetadataRetriever; import android.os.Bundle; import android.os.Environment; import android.widget.ImageView; public class VidualTestActivity extends Activity { /** Called when the activity is first created. */ File file; ImageView img; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); img = (ImageView) findViewById(R.id.img); File sdcard = Environment.getExternalStorageDirectory(); file = new File(sdcard, "myvid.mp4"); MediaMetadataRetriever retriever = new MediaMetadataRetriever(); try { retriever.setDataSource(file.getAbsolutePath()); img.setImageBitmap(retriever.getFrameAtTime(10000,MediaMetadataRetriever.OPTION_CLOSEST)); } catch (IllegalArgumentException ex) { ex.printStackTrace(); } catch (RuntimeException ex) { ex.printStackTrace(); } finally { try { retriever.release(); } catch (RuntimeException ex) { } } } } In getFrameAtTime() I'm passing different static time values like 10000, 20000, etc. in milliseconds, but still I'm getting the same frame from the video. My goal is to get different frames with a different time interval.

  • Is there a technical way to speed up a general program above current PC speed limit?

    - by Maksee
    Let's imagine I developed a Windows console application implementing some algorithm calculating something. Let's say it doesn't use any threads, just straightforward linear approach with ifs, loops and so on. Is there any technical way to make if run it 100x times faster than on the most advanced current PC? For example one of the way would be to run it on a super computer that emulates i386 faster than any of the existing PCs. But in this case the question what computer and does it really have ability to emulate Windows. In other words, is there real examples of such approach? Although in general it looks useless, but if there is a way, one could develop some program on his general home computer and pay for running it much faster on some other hardware. I suppose that this question could be asked on superuser.com, but since there are possible specific with such things as assembler instructions or threads, I thought that stackoverflow.com is better

  • How can I accelerate the generation of the an MD5 Checksum within vb.net?

    - by Richard
    I'm working with some very large files residing on P2 (Panasonic) cards. Part of the process we employ is to first generate a checksum of the file we are going to copy, then copy the file, then run a checksum on the file to confirm that it copied OK. The problem is, is that files are large (70 GB+) and take a long time to complete. It's an issue since we will eventually be dealing with thousands of these files. I would like to find a faster way to generate the checksum other than using the System.Security.Cryptography.MD5CryptoServiceProvider I don't care if this means using a specialized hardware card, provided it works and is not to ungodly expensive. I would prefer to have a method of encoding that provided some feedback as to how far the process has gone along so I can display it like I do now. The application is written in vb.net. I would prefer to be able to use it as component, library, reference within my application, but I'm willing to call an outside application if there is enough improvement in the speed of generating the checksum. Needless to say, the checksum must be consistent and correct. :-) Thank you in advance for your time and efforts, Richard

  • Nginx flv audio pseudo stream works but video is not loading

    - by sarah
    I am working on a development server for a company & they want nginx webserver to work with. So the requirements for their company is, it should be capable of doing following things i.e hotlink protection, mp4 & flv pseudo stream & secure streaming. However nginx fulfills their requirements and i am configuring their server from past 2 days as i am new to this field so i've only acheived hotlinking prevention in past 2 days. But the problem on which i am stuck is flv pseudo streaming, to make work to mp4 pseudo stream it was just a piece of paper but i am really fuc*ed up with flv pseudo stream. I have converted my flv videos with flvmdi tools to insert many keyframes but the problem is , when i try to seek video from following keyframes that are generated by flvmdi i.e test.flv?start=2681223, video does not load but audio pseudo works fine. So it means no problem with my flv configuration in nginx.conf file. And the forum that i used to compile my nginx-1.2.1 is http://h264.code-shop.com/trac/wiki/Mod-H264-Streaming-Nginx-Version2 & by adding additional module --with-http_flv_module. This forum is really active, hopes i will resolve my problem as soon as you guys will provide me some guide.

  • Not able to play videos (from youtube) in WebView

    - by user1205193
    I am using a webview to display a video (could be from youtube or vimeo) in my app. In order to not load the video webpages in the default Android Browser, I am also extending the WebViewClient so I can override the shouldOverrideUrlLoading method. This way the video webpage loads successfully in the WebView. However, when I click on the embedded video on the WebView, it does not play. If I do not override the shouldOverrideUrlLoading method, and let the video webpages load in the default Android browser, the videos work just fine. Any ideas why the videos are not working in the WebView? Also, the main reason why I overrode the shouldOverrideUrlLoading method is because if I do not do that, then when I exit the Android browser to come back to my activity (by hitting the back button on the phone), I see a white screen. Upon hitting the back button twice, I am able to get back to my Activity. I am using the emulator to do this test. Here is my code: public class YoutubeLink extends Activity { WebView myWebView; String video_url; private class HelloWebViewClient extends WebViewClient { @Override public boolean shouldOverrideUrlLoading(WebView view, String url) { view.loadUrl(url); return true; } } @Override protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); setContentView(R.layout.youtubelink); //Retrieving data from ListSample.java Bundle extras = getIntent().getExtras(); if(extras !=null) { video_url = extras.getString("video_url"); Log.d("inside YoutubeLink.java", video_url); } myWebView = (WebView) findViewById(R.id.web); myWebView.getSettings().setJavaScriptEnabled(true); myWebView.setWebViewClient(new HelloWebViewClient()); myWebView.loadUrl(video_url); } @Override public boolean onKeyDown(int keyCode, KeyEvent event) { if ((keyCode == KeyEvent.KEYCODE_BACK) && myWebView.canGoBack()) { myWebView.goBack(); return true; } return super.onKeyDown(keyCode, event); }}

  • Get Matrox Millenium video card working in Ubuntu 9.10

    - by wcoenen
    I have installed Ubuntu 9.10 on an old PC and it is mostly working, except for some heavy drawing defects that show up whenever I start dragging a window or scrolling inside a window or menu. It looks like the video driver copies the rectangle being moved to the wrong location. I have taken a look in /var/log/Xorg.0.log and the following line shows the detected video card: (--) PCI:*(0:0:8:0) 102b:0519:0000:0000 Matrox Graphics, Inc. MGA 2064W [Millennium] rev 1, Mem@ 0xf9800000/16384, 0xfb000000/8388608, BIOS @0x????????/65536 (==) Using default built-in configuration (30 lines) (==) --- Start of built-in configuration --- Section "Device" Identifier "Builtin Default mga Device 0" Driver "mga" EndSection How do I fix the drawing defects? It turned out that the 24 bit color depth (automatically selected by ubuntu 9.10) was the problem; apparantly the mga driver doesn't handle this well for cards with little memory. I took the following steps to resolve the issue (you can skip the first three steps if you already have a semi-working xorg.conf file): Reboot ubuntu in recovery mode, to get a root console without X running. Run Xorg -configure to generate a xorg.conf.new file Copy the file to /etc/X11/xorg.conf with cp xorg.conf.new /etc/X11/xorg.conf (assuming it didn't exist yet; that's why I generated it) Open the new config file with sudo nano /etc/X11/xorg.conf and make sure the screen section is configured for 16 bit color depth like this: Section "Screen" Identifier "Screen0" Device "Card0" Monitor "Monitor0" DefaultDepth 16 SubSection "Display" Viewport 0 0 Depth 16 Modes "1024x768" EndSubSection EndSection I can't guarantee those were the only important changes I made - I tried a few things in my attempts to create a valid xorg.conf file. But I'm pretty sure that the screen section was the important part.

  • What OpenGL functions are not GPU accelerated?

    - by Xavier Ho
    I was shocked when I read this (from the OpenGL wiki): glTranslate, glRotate, glScale Are these hardware accelerated? No, there are no known GPUs that execute this. The driver computes the matrix on the CPU and uploads it to the GPU. All the other matrix operations are done on the CPU as well : glPushMatrix, glPopMatrix, glLoadIdentity, glFrustum, glOrtho. This is the reason why these functions are considered deprecated in GL 3.0. You should have your own math library, build your own matrix, upload your matrix to the shader. For a very, very long time I thought most of the OpenGL functions use the GPU to do computation. I'm not sure if this is a common misconception, but after a while of thinking, this makes sense. Old OpenGL functions (2.x and older) are really not suitable for real-world applications, due to too many state switches. This makes me realise that, possibly, many OpenGL functions do not use the GPU at all. So, the question is: Which OpenGL function calls don't use the GPU? I believe knowing the answer to the above question would help me become a better programmer with OpenGL. Please do share some of your insights.

  • convert flv to mp3 with Java

    - by krial
    Hi, I'm pretty new in developing programs in Java. I'm currently writing a program that converts a flv video into mp3. I have already written such a program in Visual Studio.net C#, but the Problem is, that it isn't cross platform compatible... I used the ffmpeg binary to convert the video into mp3, but I can't find ffmpeg binaries for Mac and Linux. (if so, I could start the specific binaries from java, depending on the OS) So I tried to convert the video with Xuggle, but the final mp3 has 0 bytes. My current code is the following: IMediaReader reader = ToolFactory.makeReader("video.flv"); reader.addListener(ToolFactory.makeWriter("music.mp3", reader)); while (reader.readPacket() == null) do {} while(false); Thanks in advance. p.s sorry for my bad english

  • youtube api: display speaker statements like a caption

    - by zmol
    I'm doing something similar to close caption but not exactly the same. I have a youtube video, and I want to display certain messages at specific points in the video. When the video loads, I pull entries from the database in the format time and sentence. For example, at 0:20 the speaker says "don't forget to write down my email that you see on the side" and I want to display the email on the side. At 0:50, he says "and I'll post my office hours" so I want to show those office hours at that time. How can I do this. The video itself is hosted on youtube, but is being displayed on a private website. The div where I want to display the messages is <div id="write">.

  • Quicktime logo! Can it be hidden / disabled?

    - by decbrad
    Hi there, just wondering if it is possible to hide/disable the quicktime logo when displaying .MOV video on my site? Because the size of the video is large (3MB), I have included a rotating loading animation, however once the video player loads, the Quicktime logo hides the animation, which makes the user less likely in my opinion to wait for the movie to load? Any advice would be great! Cheers! Decbrad

  • Display on secondary video card (Nvidia 8400 GS): horrible refresh, bogs system

    - by minameismud
    This is my work computer, but it's a small shop. We do business software development. The most hardcore thing we create is some web animations with html5 and fancy javascript/css. The base machine is a Dell Precision T3500 - Xeon W3550 (3.07GHz quad), 6GB ram, pair of 500GB harddrives, and Win 7 x64 Enterprise SP1. My primary video card is an ATI FirePro V4800 1GB in a PCIe slot of some speed driving a pair of 23s at 1920x1080 through DisplayPort-HDMI adapters. The secondary card is an NVidia GeForce 8400GS in a PCI slot driving a single 17" at 1280x1024 through DVI. On either of the 23" monitors, windows move smoothly, scroll quickly, and are generally very responsive. On the 17", it's slow, chunky, and when I'm trying to scroll a ton of content, Windows will occasionally suggest I drop to the Windows Basic theme. I've updated drivers for both cards, and I've gotten every Windows update relating to video. Specifically: ATI FirePro Provider: Advanced Micro Devices, Inc Date: 6/22/2014 Version: 13.352.1014.0 NVidia 8400 GS Provider: NVIDIA Date: 7/2/2014 Version: 9.18.13.4052 Unfortunately, new hardware isn't really an option. Is there anything I can do software-wise to speed up the NVidia-driven monitor?

  • Two video card on one Mobo

    - by InfinityKing
    I recently purchased a new HP Pavilion p6-2265eo. It was then that I realised that it has only one DVI and one HDMI output.. I will connect my TV with the HDMI. so I am letft with only one DVI output. I need to have two monitors. Please help. Should I purchase a new video card and install it? My knowledge is limited. The specifications of my comp says that there is 1 x PCI-E x16, 3 x PCI-E x1. 1) I suppose that the video card already present in my purchase is connected on the PCI-E x16. Am I right? I dont want to open my desktop right now and check it for myself as it can void the warrenty. so I need an experienced person to tell me that. 2) I have an old nvidia geforce 7200 gt. Is it possible for me to connect it to my left over PCI-E x1? I searched for PCI-E x1 on the net and as far as I can understand the slot is too small for my old nvidia geforce 7200 gt graphic card. 3) what are the options? Please help this dummo :) Thankign you in advance,
