It's simple to the point of blasphemy, and it feeds perfectly into any number of other sources (even across operating systems and 32/64-bit boundaries with avs2yuv).

Many common encoders do it, and it's usually followed by one of the many free/open-source muxers (mp4box, lsmash, avc2avi, etc). Simple, just one more (usually automated) step. Really, coding up a storm just to avoid something as innocuous and easy to deal with as elementary streams might be a tad bit of an overkill. :) There’s no need to fear producing a raw bitstream.

It's a small 32-bit Windows video server that grabs frames from videos and dumps them into shared memory, which can be accessed by pretty much any other Windows program. I have a fairly simple C++ interface as well as a Matlab interface so you can load in almost any video (I've tested FLV, WMV, AVIs, etc) into 32-bit/64-bit Matlab or C++. It isn't terribly well tested, but it works for me so if you want a copy, I can provide a copy.

I just tried Tigervnc on my 32 bit gentoo system and was impressed. This is a major step forward over older vnc code, I guess the jpeg enhancements are a significant part of it. I've been trying to build Tiger on x64 ubuntu since that's the target system but as the README points out it's a bit of jive. I've found some i386 packages have been put up but nothing for x64. Since you seem well equipped and testing on that platform is there a possibility of posting some binaries or at least build instructions for x64? I guess if I spend a few days messing about I could work out how to do it but it does seem like a heavy case of reinventing the wheel. Any instructions from an accomplished wheel-wright would be a great help! ;) Hi DRG.

The "ipp_gzip" sample application provides a way to compare threading performance at different levels over different data set sizes. Unlike your JPEG test, this application implements a lossless compression and decompression algorithm; a similar evaluation might be useful to further illustrate how the choice of threading versus the size of the data set can influence the results.
