Red October

Red October is JRiver's breakthrough invention for managing DirectShow filters on Windows. It takes the work out of downloading, installing, and configuring the DS filters that are used for high quality playback of video. It offers two levels. Red October Standard will work on all machines. Red October HQ uses the madVR Renderer and will work on high performance PC's.

DirectShow: The Problem

JRiver Media Center is one of several DirectShow capable video players.

Let's start with what DirectShow is. Then we will go on to what its weaknesses are, and eventually to our new solution.

Years ago, Microsoft launched DirectShow technology, a method of handling audio and video with what we could call "interchangeable parts". Any player that is DS compatible can theoretically load and use any DS filters. In theory it offers a way to standardize processing and playback of media.

Seriously? Why do I need to know about all this stuff just to make video playback work?

For the less technical, a "filter" is a piece of software that can be strung together with others to create a "graph", something like a chain of beads. At the beginning there may be a reader (to read the file), then a spltter (to separate audio from video), various decoders (to decompress the audio and video), and a renderer (to paint the picture on the screen).

Microsoft also devised a "merit" system to allow competing filters to nominate themselves for insertion in the graph. This is one of the big problems with DirectShow, in my opinion. It allows bad filters to be chosen instead of good filters, so it causes a lot of problems at playback time.

We've wrestled with this problem for several years. Each machine usually has a number of filters installed, and they often don't work well when the graph is built. Our solution has been a little lame, I admit. When a user had a problem, we suggested installing CCCP, a well known filter "pack" that included "good" versions of ffdshow, haali, and other filters. This often worked.

We also pointed users to an excellent DirectShow Playback Guide, written by one of our expert users, glynor. You can see what a wall of text it was, though, and configuring these filters to be well behaved was a troublesome prospect at best for most mere mortals.

Usually one of these two remedies worked, but not always.

Red October: The Solution

So we began thinking about including our own filter pack and setting it up ourselves. About the same time, LAV and madVR came to our attention.

As a result, JRiver Media Center now has a new DirectShow technology that we call Red October. It has these modes:

• Red October JRVR: Recommended mode, using JRiver Video Render ([JRVR]), for ease or use, efficiency, and high quality. It just works.

• Red October Standard: It uses the standard Microsoft Enhanced Video Renderer (EVR). We build the graph and don't allow anything else. This results in video playback that works and looks good.

• Red October HQ: Uses madVR as the renderer. This is more GPU intensive, so it works best on fast, modern GPUs. Check out the System Requirements article for more details on suggested system specs.

NOTE: All modes automatically download, install, and configure known good versions of LAV and other filters as are needed.

No Configuration Required

Everyone can set video playback to Red October (Standard or HQ) and let MC do the rest! For most users, this will not only be simple, but will result in highly optimized playback quality.

Configuration Still Possible

For the experts who like to tinker, we added three advanced modes:

• Red October Standard with additional filters -- Our base plus your additional filters.

• Red October HQ with additional filters -- Our base plus yours again.

• Windows Merit Based -- the same as the original Windows DirectShow selection.

In addition, Red October uses its own location and settings for all filters, and we "register" them ourselves, so there is no conflict with other players. Red October also ignores the Windows Merit system and it has a white list for additional good filters.

MC can now set a default that we know will work. Even a novice can now get the highest quality DirectShow playback without suffering the pain of DS configuration. And the dedicated tweaker will still find room to play.

Acknowledgements

We're very grateful to nevcairiel, madshi, jmone, glynor, SamuriHL, and many others who helped guide this and upon whom we depend for sage advice.

I am extremely grateful to John Thompson and Matt Ashland, who helped create this amazing new system. It's one of the best projects JRiver has ever done.
