media

I am having an issue where occasionally the MediaPlayer.create method will return null, even though the audio file is definitely there. In fact, if I put the call to create into a while loop, the media player will eventually be created successfully. This only seems to happen on my phone (HTC Hero running 2.1) and never in the emulator. Is this just an issue with the phone? Or is there a different way I should be playing these audio files? Note that I want to be loading them dynamically which is get I am making the call to getIndentifer. If there is a better way of playing these dynamically

I want to play a m3u file songs in a player I am using the following player, but it's not playing: <OBJECT ID="MediaPlayer1" CLASSID="CLSID:22d6f312-b0f6-11d0-94ab-0080c74c7e95" CODEBASE="http://activex.microsoft.com/activex/controls/mplayer/en/nsmp2inf.cab# Version=5,1,52,701" STANDBY="Loading Microsoft Windows® Media Player components..."

i am currently working on .net application which contains one audio & video file. audio file is split as in to small section as per database entries. then we have to merge this files on video file at specific positions.we what something like windows movie maker it will be nice if someone suggest some .net based sdk for this. You can use ffmpeg for this purpose. But you will need a .net wrapper to make it usable in C#. You can use ffmpeg-sharp or SolidFFMpeg . its a a wrapper library over the FFmpeg multimedia suite that provides easy to use wrappers for use in C#. Datastead Software's

Do anyone know what MFTransform should I use to convert a 'MJPG' MFSample to 'YUY2' or 'RGB24'? Any tip will be very appreciated. Thanks Since the number of visits to this post was noticeable I'm going to answer my own question. The trick is to enum all the transformations between MJPG and YUY2 since it seems there isn't direct transformation between MJPG and RGB32. To transform the image between YUY2 and RBG32 use the color converter DSP: http://msdn.microsoft.com/en-us/library/windows/desktop/ff819079%28v=vs.85%29.aspx I use this method to fetch samples from a 1080p webcam and then decoding

Please help me calculate decibels from phone microphone. The microphone has a getMaxAmplitude() function. How I can I use it to calculate decibels? I read in some forums that the decibel calculation formula is power_db = 20 * log10(amplitude / reference_amplitude) . But I don't understand how to find the reference_amplitude . Decibels are a unit widely used to define some quantity relative to something else. There are a number of different types of decibel measurements, depending on what you're trying to describe about the signal you're receiving. Read this link to get you started, it explains

Is it easy to write some .Net code to record screen and audio (from computer mic), then output to an wmv file. Any reference code? BTW: I searched all codes from WME SDK, no such sample code. thanks! George Microsoft and the content mafi^H^H^H^Hindustry are trying their best to make this impossible. You will be far better of searching for "open source screen audio capture" than browsing any officially supplied documentation/example code - I would be seriously surprised if Microsoft provided anything relevant. Check out the SDK that's available for Techsmith Camtasia : Camtasia is a full-screen

I was wondering what (if any) shims you use to get the magic grids to respond correctly in SUSY in IE8 and under? On non-susy sites I've always used moderizr or the shim from google and they worked as expected. I'm working on my first SUSY site and the media queries for the largest size won't kick in. http://dev.apehangar.com It's not clear to me what sort of "shim" you are looking for. I don't know any good way to make MQs work in IE8, but Susy does have an option to output styles under a fallback class . Those styles wont respond dynamically, but you can use it to send IE a desktop site:

i want to know how can i extract images from a video using JMF. Player player = Manager.createRealizedPlayer(cdi.getLocator()); player.start(); FrameGrabbingControl frameGrabber = (FrameGrabbingControl) player.getControl("javax.media.control.FrameGrabbingControl"); ////////////////////////////// private Image grab() { Buffer buf = frameGrabber.grabFrame(); // Convert frame to an buffered image so it can be processed and saved Image img = (new BufferToImage((VideoFormat) buf.getFormat()).createImage(buf)); return img; } for more info see complete example: http://www.comp.rgu.ac.uk/staff/fh
