  • Capture Video of Android's Screen

    - by Taranfx
    Forget screenshots, is it posible to capture a video of the running application in android? Rooted or non-rooted, I don't care, I want atleast 15fps. Update: I don't want any external hardware. The intent is to make it perfectly portable and every frame is captured within Android OS. If it crosses the boundaries of the app sdk, I'm willing to go to OS level modifications but I would need a starting point.

  • How to determine whether or not a video format is supported

    - by Tal Even-Tov
    Hi, I've had to write an application that lists and plays tutorial videos along with accompanying text. It works well but since the videos are added by the user I need a way of checking to see whether or not a video can be played on the machine. I'm not sure whether or not there is an easy way to try test the file (and catch errors) or if I need to start looking at codecs installed. Does anybody have any experience with this?

    - by pinaldave
    Is SQL boring? Not at all. SQL is fun – one has to know how to maximize the fun while working with SQL Server. Earlier I was invited to participate in the video Pluralsight.

Before I say anything I suggest all of you watch the following video. Make sure that you pay special attention after 0 minute and 36 seconds. What I can say about this. I am just fortunate to be part of the history in the making. There are more than 53 super cool celebrities in this video. In this just over 3 minute video there are so many story lines. I must congratulate director Megan and creative assistant Mari for excellent work. There are so many fun moments in this small video. Let me list my top five moments. @John_Papa ‘s dance at second 14 @julielerman playing with cute doggy The RACE between @josepheames and @bruthafish – the end is hilarious The black belt moment by @boedie @stwool relaxing on something strange! Well, this is indeed a great short film. This video demonstrates how cool is the culture of Pluralsight and how fun loving they are. A good organization provides an environment to its employees and partners to have maximum fun while they all become part of the success story. Hats off to Aaron Skonnard for producing this fun loving video. Well, after listening to this song for multiple times, I decided to give a call to Pluralsight.

  • ASP.net FFMPEG video conversion receiving error: "Error number -2 occurred"

    - by Pete
    Hello, I am attempting to integrate FFMPEG into my asp.net website. The process I am trying to complete is to upload a video, check if it is .avi, .mov, or .wmv and then convert this video into an mp4 using x264 so my flash player can play it. I am using an http handler (ashx) file to handle my upload. This is where I am also putting my conversion code. I am not sure if this is the best place to put it, but I wanted to see if i could at least get it working. Additionally, I was able to complete the conversion manually through cmd line. The error -2 comes up when i output the standard error from the process I executed. This is the error i receive: FFmpeg version SVN-r23001, Copyright (c) 2000-2010 the FFmpeg developers built on May 1 2010 06:06:15 with gcc 4.4.2 configuration: --enable-memalign-hack --cross-prefix=i686-mingw32- --cc=ccache-i686-mingw32-gcc --arch=i686 --target-os=mingw32 --enable-runtime-cpudetect --enable-avisynth --enable-gpl --enable-version3 --enable-bzlib --enable-libgsm --enable-libfaad --enable-pthreads --enable-libvorbis --enable-libtheora --enable-libspeex --enable-libmp3lame --enable-libopenjpeg --enable-libxvid --enable-libschroedinger --enable-libx264 --enable-libopencore_amrwb --enable-libopencore_amrnb libavutil 50.15. 0 / 50.15. 0 libavcodec 52.66. 0 / 52.66. 0 libavformat 52.61. 0 / 52.61. 0 libavdevice 52. 2. 0 / 52. 2. 0 libswscale 0.10. 0 / 0.10. 0 532010_Robotica_720.wmv: Error number -2 occurred here is the code below: <%@ WebHandler Language="VB" Class="upload" %> Imports System Imports System.Web Imports System.IO Imports System.Diagnostics Imports System.Threading Public Class upload : Implements IHttpHandler Public currentTime As System.DateTime Public Sub ProcessRequest(ByVal context As HttpContext) Implements IHttpHandler.ProcessRequest currentTime = System.DateTime.Now If (Not context.Request.Files("Filedata") Is Nothing) Then Dim file As HttpPostedFile : file = context.Request.Files("Filedata") Dim targetDirectory As String : targetDirectory = HttpContext.Current.Server.MapPath(context.Request("folder")) Dim targetFilePath As String : targetFilePath = Path.Combine(targetDirectory, currentTime.Month & currentTime.Day & currentTime.Year & "_" & file.FileName) Dim fileNameArray As String() fileNameArray = Split(file.FileName, ".")

  • how to uninstall program that is not listed in the uninstaller

    - by Nrew
    I really love this video converter called total video converter. But there's one thing that it annoys me about it. The video player which is installed along with it. And the installer doesnt even allow you to customize. The video converter is installed along with the video player. And if you search for the total video player in the uninstaller. Nothing is there except for total video converter. What do I do?Can I go into the registry and delete something there so that I can rid of this video player installed along with total video converter?

  • Insert video clip in a lyx presentation and play it in GNU/Linux.

    - by Orjanp
    How can I insert a video clip into a presentation created in Lyx? Have seen http://www.latex-community.org/forum/viewtopic.php?f=19&t=48. It works, but there the video starts in the background in an external player. I would prefer it to be played in the presentation itself. If an external player is used it it should at least start in the foreground. But the presentation takes the foreground. Using evince in GNU/linux as pdf viewer. Beamer is used as a presentation template. Is it possible to play a video file in an embedded player in the presentation itself? Created an example presentation.

  • Compress Large Video Files with DivX / Xvid and AutoGK

    - by DigitalGeekery
    Have you ever recorded home video on a camcorder only to find the video size is enormous? What if you wanted to share a video clip on YouTube or another video sharing site, but the file size was bigger than the maximum upload size? Today we’ll look at a way to compress certain video files, such as MPEG and AVI, with Auto Gordian Knot (AutoGK). AutoGK is a free application that runs on Windows. It supports Mpeg1, Mpeg2, Transport Streams, Vobs, and virtually any codec used for an .AVI file. AutoGK will accept as input the following file types: MPG, MPEG, VOB, VRO, M2V, DAT, IFO, TS, TP, TRP, M2T, and AVI. Files are output as .AVI files and are converted using the DivX or XviD codecs. Installing and Using AutoGK Download and install AutoGK (link below) Open the AutoGK. You’ll need to navigate a few wizard screens, but you can just accept the defaults.   Choose your video file by clicking on the folder to the right of the Input file text box.   Browse for and select your video file and click “Open.”   For this example, we’ll be working with an .AVI file that’s 167MB in size.   The output file is copied into the same directory as the input file by default, but you can change this if you choose. If the input file is also .AVI, AutoGK will append an _agk to the output file so that the original is not overwritten. Next, you’ll see any audio tracks listed. You can unselect the check box if you’d like to remove the audio track. You can choose one of the Predefined size options… Or, select a Custom size in MB or Target Quality in percentage. For our example, we’ll be compressing our 167MB file to 35MB. Click on Advanced Settings. Here you can choose your codec, if you have a preference, as well as output resolution and output audio. If you’d like to use the DivX codec, you’ll need to download and install it separately. (See link below) Typically you’ll want to keep the defaults. Click “OK.” Now you’re ready to add your file conversion job to the Job queue. Click Add Job to add it to the queue. You can add multiple files conversions to the job queue and  convert them in one batch. Click Start to begin the conversion process. The process will begin. You’ll be able to see the progress in the Log window on the bottom left. When the conversion is complete you’ll see a “Job finished” and the total time in the log window.   Check your output file to see it’s compressed size. Test your video just to make sure the output quality is satisfactory.   Note:  Conversion times can vary greatly depending on the size of the file and your computer hardware. Files that are several GBs in size may take several hours to compress. AutoGK is no longer being actively developed but is still a wonderful DivX/XviD conversion tool. It can also be used to compress and convert non-copy protected DVDs.

  • Adding video and flash functionality to the Ajax Control Toolkit HTMLEditor

    - by Beerdude26
    Greetings, I'm looking for a way to extend the functionality of the HTMLEditor control that the Ajax Control Toolkit supplies for ASP.net. I would like to add video and flash functionality to the editor (buttons, allowed tags, etc). To my knowledge, this is rather easy: plop in an tag with the correct parameters and it just works; I have videos running in the preview window of the editor. Unfortunately, the tag is stripped away when saving the HTML-code and updating it in the database. Hence, I would like to ask if there is any way of adding this functionality apart from manually adding the changes in the source control repository of the Ajax Control Toolkit and recompiling it. If this is not possible, but can offer some help concerning the implementation of this in the source code, it would also be much appreciated. Thank you for your time :)

  • Forth: free video tutorials?

    - by Peter Mortensen
    Can you recommend any free Forth video tutorials (except for following) ? The only one I know of is Samuel A. Falvo's excellent "Over The Shoulder Episode 1: Text Preprocessing in Forth". MPEG. 102 MB. There are also videos from the annual Forth Day, but I don't consider those to be tutorials. (Unfortunately Forth is, like R, C, C++, Java, C#, D, COM, .NET, F# and Frontier, an unspecific search term. Search tip for Forth: qualify it with "ans" - as in ANS Forth, the ANSI Forth Standard.) Accumulated based on answers and other information: Introductions to Forth Forth. By Ben Stiglitz. At RubyConf 2008 Orlando Florida, U.S.A. 13 min 35 secs. 32 MB. MP4.

    Hi out there, my challenge is to built a video portal, based on wordpress (blog already started). so in the backend there must be a option to add, tag, descripe videos and in frontend the videos must have a comment function, must be searchable and so on. wordpress gives already a large amout of functionallity and i want to use this, comments for example, but also categorisation and tagging. what is the best practise to built such a "plugin" ? where to start? what to use? custom tables and built everything by myself or can i use the blog functionallity to advantage? hopefully everything is clear, comment if not ;)

  • Does android support playlists for video files?

    - by DanJ
    I'm and android beginner, so go easy on me ;-) I'm trying to play a sequence of video files which I'm downloading from a server. The challenge is that I want to have a smooth transition from one file to another. My thought is to have two MediaPlayer instances each preparing and then playing in turn. It is not clear to me if they can both share the same SurfaceView? Or maybe, I should be using different views and swapping between them? Or, the idea is a bad idea all together? When I try to run configure the MediaPlayer instance with a view that isn't visible it seems to crash my emulator.

  • Accessing HTML 5 Video Progress Event with jQuery

    - by jnolte
    Hello All, The below is for an HTML5 video player event. My partner and I have been stumped for a very large portion of the day on this issue and hope someone can lend some insight on the issue. We have been able to access the progress event with plain js as seen below but when trying to access this with jQuery we get undefined in console. Any help/ recommendations are greatly appreciated. //JS - Works like a charm document.addEventListener("DOMContentLoaded", init, false); function init() { var v = document.getElementById('test-vid'); console.log(v) v.addEventListener('progress', progress, false); } function progress(e) { console.log(e.lengthComputable + ' ' + e.total + ' ' + e.loaded); } // jQuery - NO BUENO - Undefined rendered in console var vid = $('#test-vid'); $(vid).bind("progress", function(e){ console.log(e.total + ' ' + e.loaded + ' ' + e.lengthComputable ); }); Thanks in advance, JN

  • Raw Video file from website

    - by Charlie
    I would like to make an app that will download videos files that can be played later. At first i thought I could have a UIWeb view and then try to access the cache of it and get the file that way but unfortunately i don't have access to that. After trying that my next thought would be get the direct link to the video file. Essentially what download helper does on fire fox. Any idea of where i could look at for help or any body have any better idea? Is there any stringByEvaluatingjavascript that might be of use or is there away to access the cache on a webview in your own app? Thanks for any help!

  • Video Streaming

    - by Josephe
    First I need to state that I am not the developer so I will state the issue in business terms but please respond with a technical solution as I will be passing on your posts to the developer. We are building a web based application in SilverLight and WPF that consists of communication between a customer service rep and a customer. The application will inlcude a webcam that will provide the customer with the ability to see the customer service rep and the rep will also be able to see an image of themselves but will not be able to see the customer. Similar functionality to a live web chat with video component. There could potentially be bandwidth issues and we do not want the customer to have to download anything. Any recommendations on how to do this?

  • video streaming

    - by mawia
    Hi! all I am designing an application for streaming video.I have developed a model in which a server wait for incoming request.The server it self is serving to a good number of clients and it can't afford to serve any more clients.Now when the new connection comes,the server chooses from among it's clients a candidate client who will serve the request of the incoming client.Now the thing is that this choice should be very intelligent.Now I am using various heuristic like bandwidth of the selected client,it's location,distance from the requesting client to come at a decision.Now my question is,IS THERE AVAILABLE ANY TOOL TO FIND OUT BANDWIDTH,LOCATION of a host,and DISTANCE(my be in hop number)?for hop number I can use traceroute but that will be too expensive as it take long time sending reply from every intermediate router. Any help will be appreciated. Thanks!

  • FFmpeg + iPhone - Interesting (incorrect?) video encoding results

    - by jtrim
    I'm encoding some video on the iPhone by running the png image data through swscale to get YUV420P data then encoding that frame using the MSMPEG4V1 codec. In the api docs, avcodec_encode_video should return the number of bytes used from the output buffer by that encode operation. There are 234,000 bytes going into the encoder, but the result returned by avcodec_encode_video is simply "4". The result is exactly the same over 24 frames. Something seems fishy here...any insight? Here's a pastebin link to the code: http://pastebin.com/ht94FWva (sorry for the link away from SO, I just didn't want to have the code duplicated in several places) EDIT: Also, I've set up a custom log callback for ffmpeg to use and I have the log level set to "Verbose" (libavutil/log.h), so libavcodec should be logging any goofs to the console, but avcodec is quiet throught he whole operation. (note: I did test to make sure my log callback was working)

  • How do I play a video through .net in windows 7

    I had setup an app to play a video using the library suggested here this worked great for me for a long time until my machine was upgraded.

  • Formula for Live Video Streaming Bitrate

    - by MD
    I am simply looking for the formula that should be used here. All the results I've found base "finding the bitrate" off of already existing video. I'm talking about LIVE streaming. (indeterminate length) So, I know some basic parts of it, but I just need to know if I'm right or missing anything. For Kbps: Resolution * Framerate / 1024 Is it really that simple? Audio would be a separate element for our purposes here. Am I missing anything from this formula? (Coming up with a proposal of what amount of bandwidth would be required, relative to possible resolution options, so I just need to be sure that I'm not missing anything or inaccurate about it)
