I am looking to release a video on memory stick (more likely) or DVD (less likely) that has protection against duplication and expires after a certain date. We basically have a video we want to sell the video to clients, but in the industry, it's common for companies to trade and duplicate what they have purchased, even to their competit...
Hi everyone, I've a project at the moment, in Java, which uses a filetype which is inherently in the YCbCr colorspace. Within this, there is a lot of number crunching happening behind the scenes (which I've had to code) to convert to RGB from the YCbCr values. This is done per-pixel, per-frame, at 25 frames per second... The project mu...
I'd like to learn the gstreamer media framework. Where should I start? ...
Greetings - My cell phone records videos into a strange (to me) format, .3G2. I would like to convert it to a more common format, like WMV or AVI. Does anyone know of a simple and free tool that can do this? Thanks - Jordan ...
I'm using the AVIFile Wrapper to create video from my WPF app. I'm using CompositionTarget to grab an image for each frame but I'm having problems with framerate. As my app slows down with heavy data load, the CompositionTarget frame rate drops. With less video frames, when I play back these parts appear as fast forward. Is there a vide...
Hello, I need a way to extract the audio from some video (in PHP). I have the video streaming in from YouTube, so I would really like it if it were on the fly streaming, not I have to save it to a temp directory and process it there (though that is acceptable.) Thanks, Isaac Waller Edit: to be more specific, I have a MP4 and I want it to...
I'm playing with the flash.media.Video and the Camera with Actionscript, and it bugs me that the video cam is showing a flipped video. Let me describe with an example: When I turn to my right, the video will show me turning to my left. If I held up a peace finger sign on my right hand, it appear as if I am doing it with my left. So, ho...
I'm playing around with the flash Video cam and I'm a real puppy-dog-level newbie with Actionscript, flash and the video stuff. How do I make the video showing in black and white? I would like to say make a "black and White" feature of the video. Do I have to mess with filters? ...
I have four videos that I would like to tile in a 2x2 fashion to make a new video. Is there a way I can do this easily, preferably free and under Linux? I am willing to program a moderate amount, perhaps in order to interact with some library, but unwilling to write an entire video-processing program myself. You may assume that the in...
I want to understand how video and audio decoding works, specially the timing synchronization (how to get 30fps video, how to couple that with audio, etc.). I don't want to know ALL the details, just the essence of it. I want to be able to write a high level simplification of an actual video/audio decoder. Could you provide pointers to ...
I have a Android app. It recieves videos in .flv format which is unplayable by the Android phone. I was wondering how to convert the file to MP4. I could use FFMPEG, but I do not know how I would get it onto the phone, and how it would work on multiple phones if it was compiled for a single one. ...
I'm looking for some videos about the history of Unix/Linux and Open Source Software. I know (and have) Revolution OS. Are there any others? Edit: I'm a teacher and need resources to show students. Edit: I found Revolution OS on Google Video. ...
One of the features of the Flash app I'm working on is to be able to stream a webcam to others. We're just using the built-in webcam support in Flash and sending it through FMS. We've had some people ask for higher quality video, but we're already using the highest quality setting we can in Flash (setting quality to 100%). My understa...
Environment: Windows XP/Vista, VS2008, C#/.NET 2.0, VideoGrabber. Hi All, I'm writing an app which captures cameras input and encodes them into a movie file (including sound). My client suggests I encode the movie using the DivX codec. But it's not installed by default and it's not redistributable: Users would have to download, instal...
Can anyone explain in a simple clear way how MPEG4 works to compress data. I'm mostly interested in video. I know there are different standards or parts to it. I'm just looking for the predominant overall compression method, if there is one with MPEG4. ...
I have a static web site that need to display a video. I do not control the server (but know the guy who does). Is there any "host some files and add some boilerplate" ways to display the video as part of the page? I'm thinking of something that would look like an embedded youtube video. I'd rather keep stuff local (I don't have a youtu...
Using the tiny Diggit/Blog feature of StackOverflow described here: I would like to post the following Google tech talk video I have just saw and that I found quite interesting. I have always had problems understanding javascript "nature". Here, the JavaScript good parts are described by Douglas Crockford I hope you find this link ...
I'm the admin for a large media intensive site. We've done some experimentation with our video MIME types. We've alternated between forcing the download using Content-Disposition: attachment + Content-type: application/octet-stream and actually returning the proper MIME type. We've had complaints either way we set it up. With the prope...
Hello, In my program, it gets MP4 video in, and I want it to output a MP3 (without any server-side stuff.) Since Android (and my app) needs to run on many different hardware configurations, this means I probably cannot use FFMPEG :( I know this may be very battery and processing power intensive, especially for a mobile phone, but I need ...
I am writing a, relatively, simple program involving 3 separate monitors. Each monitor will have a button moving around that specific screen. If you click that button it will play a video on that screen. I need to be able to have each of the screens acting as if they are totally separate. I have built the computer that will be running...
