A quick glance at the present-day internet would seem to indicate that Adobe Flash is the obvious choice for embedding video in a web page. Is this accurate, or are they other effective choices? Does the choice of ASP.NET as a platform influence this decision?...
I've implemented an image/video transformation technique called discrete cosine transform. This technique is used in MPEG video encoding. I based my algorithm on the ideas presented at the following URL: http://vsr.informatik.tu-chemnitz.de/~jan/MPEG/HTML/mpeg_tech.html Now I can transform an 8x8 section of a black and white image, s...
What is the best way to transcode audio and video to show on the web? I need to do it programmatically. I'd like to do something like YouTube or Google Video where users can upload whatever format they want, and I encode it to flv, mp3, and/or mp4. I could do it on our server, but I would rather use an EC2 instance or even a web ser...
We have a custom-built Flash-based video player that I maintain, and it needs to support preroll ads and ideally both progressive video playback and streaming depending on a server switch. I've been working with the flvPlayback component but am finding myself a little out of my depth. Are there any good tutorials or resources for unders...
I'd like a concise introduction to the different options. ...
What is the best way to get and set the meta data for mp3, mp4, avi files etc. with .NET? ...
My website is entirely flash based, it moves around a 3D model which was given to me as chunks of video that I've converted to FLV files. I'm using the FLVPlayback component to control the video inside of my program. While running memory checks using System.totalMemory I've noticed that whenever a video is loaded, it will eat up a chunk ...
I would like to bypass the web-server functionality of a Sony SNC-RZ30N network attached web cam and display the video feed in a Silverlight application. I can't seem to find any examples of interfacing with the camera programatically. Any leads would be much appreciated. Thx. Update 09/09/2008: Found a good site with Javascript exam...

When I'm eating, or generally feeling bored, I like to watch a TV-series or something for entertainment. However, being somewhat of a geek, I was wondering if there were any technical video podcasts out there that I should be subscribing to? Any site that provides programming or technology-related videos for streaming or download will do...
I have a DirectShow graph to render MPEG2/4 movies from a network stream. When I assemble the graph by connecting the pins manually it doesn't render. But when I call Render on the GraphBuilder it renders fine. Obviously there is some setup step that I'm not performing on some filter in the graph that GraphBuilder is performing. Is t...
Does anybody know (or know of a resource that contains) a list of frame start codes for common video formats (MPEG-1/2/4, .wmv, .mov etc.). For example, an MPEG-1 video frame will (I think) always start with "00 00 01 00". In essence I'd like to know these so that I could write a program that can automatically find the start of frames t...
I'm looking for a good way to enumerate all the Video codecs on a Windows XP/Vista machine. I need present the user with a set of video codecs, including the compressors and decompressors. The output would look something like Available Decoders DiVX Version 6.0 XVID Motion JPEG CompanyX's MPEG-2 Decoder Windows Media Video **Availab...
There are now several places that offer free audio or video tech talks/presentations online: I'm thinking of Google Tech Talks, IT Conversations, as well as some of the sites recommended in the answers to this question. So: are there any specific presentation(s) that you consider as "must-see", either in your area of interest or for all...
I suck at math. I need to figure out how to calculate a video duration with only a few examples of values. For example, a value of 70966 is displayed as 1:10 minutes. A value of 30533 displays as 30 seconds. A value of 7007 displays as 7 seconds. ...
I would like to open a small video file and map every frames in memory (to apply some custom filter). I don't want to handle the video codec, I would rather let the library handle that for me. I've tried to use Direct Show with the SampleGrabber filter (using this sample http://msdn.microsoft.com/en-us/library/ms787867(VS.85).aspx), but...
I'm wondering how to use a VideoDisplay object (defined in MXML) to display video streamed from FMS via a NetStream. The Flex3 docs suggest this is possible: The Video Display ... supports progressive download over HTTP, streaming from the Flash Media Server, and streaming from a Camera object. However, later in the docs all I can...
What options do I have to publish Flash video from webcams other than Adobe's Flash Media Server and Red5? I would prefer a solution in .NET, Python or PHP but can't find anything. ...
How to encode video on the fly and send it trough the network from C#? Can't find a suitable library. I need to encode in WMV and don't mind if the actual encoding is made in C++ as long as the library has a .NET assembly available. Thanks ...
On JavaFX's Wikipedia In May 2008 (...) Sun Also announced a multi-year agreement with On2 Technologies to bring comprehensive video capabilities to the JavaFX product family using the company's TrueMotion Video codec. Do you know if it will include encoding capabilities for webcam video like Flash or just playback/stre...
