I'm working on our encoding software, and have come across a strange issue where files in a 16:9 aspect ratio are being played in 4:3 in some players, post-transcode from WMV to MP4. Using ASF view I can see that the source WMV file appears to have incorrect data in its BITMAPINFOHEADER structure (it reports that is has 4:3 dimensions bu...
Hello, I've been trying to find a good video that I can show at a "Lunch and Learn" on Agile Development / Scrum. Our organization is primarily Waterfall and most people have never even heard of Agile development let alone have any concrete knowledge of the topic. There are plenty of great resources out there that talk about Agile, but ...
I'm working on a video streaming application in Flash and I've been told I need to add quality selection tools. The requirements are "low", "medium" and "high" quality. I'm trying to figure out what kinds of quality settings to actually apply for this (framerate and video quality settings). I feel like there has to be some kind of sta...
This is a problem I have been dealing with for a while, and haven't been able to get a good answer (even from Microsoft). I'm using the generic dump filter to write hardware compressed MPEG files out to disk. In the graph, I also have a SampleGrabber filter that gets called on every frame. From the SampleGrabber callback, I get a subt...

I have a requirement to build a very simple streaming server. It needs to be able to capture video from a device and then stream that video via multicast to several clients on a LAN. The capture part of this is pretty easy (in C#) thanks to a library someone wrote with DirectShow.Net (http://www.codeproject.com/KB/directx/directxcaptur...

I'm working on an embedded device that does not support unaligned memory accesses. For a video decoder I have to process pixels (one byte per pixel) in 8x8 pixel blocks. The device has some SIMD processing capabilities that allow me to work on 4 bytes in parallel. The problem is, that the 8x8 pixel blocks aren't guaranteed to start on...
I'm doing a project where we play multiple videos back to back, and if we load them the normal way by providing a stream url, there is a load delay each time we start the next video. I've looked through Adobe's docs for both Flash and Flex, and I can't find a way to pre-load the videos. Embedding them is not workable in this applicatio...

I'm trying to make a front end for all my music and video files on a spare PC I have but have come up against a bit of a road block. I originally wanted to stream the movies (avi, mpeg, flv etc) using a flash media player but after a bit of searching it seems that flash can only stream flv's. Obviously, I don't want to convert my whole h...
I need to encode a sequence of frames with a lossless video codec and play them in a Java app. I don't care about the file size. The output frames should match the input frames exactly. Lossy codecs don't do this even at high bit rates. None of these well-known lossless video codecs appear to be supported in JMF or FMJ: HuffYUV CorePN...
Is there a way to record the screen, either desktop or window, using .NET technologies. My goal is something free. I like the idea of small, low cpu usage, and simple, but would consider other options if they created a better final product. In a nutshell, I know how to take a screenshot in C#, but how would I record the screen, or area...
