GraphEditPlus will make each DirectShow developer`s life much easier. Edit multiple graphs, see every bit of each mediatype, control your filters and generate C++ or C# code of a working application. DirectShow development was never so easy before! Load and save .grf files compatible with MS GraphEdit. See all filters registered in the system, register new filters. Render media files. For each filter in your system you can: see in what file on hard disk it is (for VfW codecs you`ll see actual codec file, not the wrapper), see all information about its file: creation and modification times, version, vendor, size, etc., see and copy to clipboard filter`s CLSID, see and change filter`s merit, unregister filter. For each actual filter in your graph you can: see what interfaces this filter supports (scan for 280+ known DirectShow interfaces), open its property page (if present), see its own state in each moment (stopped/paused/running). Connect pins using intelligent connect and direct connect. For each unconnected pin you can: see list of its desired mediatypes, see list of filters that may connect to this pin (in the order in which DirectShow will try them when it renders pin or uses intelligent connect, you can add filters to your graph right from that list), render pin, if it supports IAMStreamConfig, set media type. For each connection between filters you can see its mediatype. For each mediatype you can see full information: not only major and sub types, but also all the fields of all popular format blocks (like VideoInfo, VideoInfo2, WaveFormatEx, etc.) including all fields of nested structures like BitmapInfoHeader etc. See what samples go through your graph (see info about each sampe going through Sample Grabber). Control your graph, see current position and duration. Once you`ve built your graph GraphEditPlus can generate source code in C++ of a simple application that builds this graph and runs it. It will include all necessary filter definitions.
