Description
This sample provides several filters that are useful for testing your own filters.
| Filter | Description |
| AlphaRenderer | This filter renders video to an alpha blended checkerboard patter, based on the alpha values in the incoming video. It uses the media subtype MEDIASUBTYPE_ARGB32. |
| RateSource | This source filter outputs video at a specified frame rate, for testing different frame rates. It also supports seeking. |
| SourceARGB | This source filter outputs RGB 32 with alpha (MEDIASUBTYPE_ARGB32), for texting alpha support in downstream filters. It also supports seeking. |
| Source8Bit, Source555Bit, Source565Bit, Source24Bit, Source32Bit | These source filters output video in various uncompressed RGB formats, for testing pin connections in downstream filters. They also support seeking. |
| TransNull8, TransNull555, TransNull565, TransNull24, TransNull32, TransNull32a | Each of these trans-in-place filters requires a particular RGB media type. They are useful for testing pin connections in upstream filters. (They do not transform the video in any way.) |
| TransSmpte | This filter draws a SMPTE time stamp on the video, for testing frame-accurate filters. You can write the output video to disk. This filter supports 32-bit RGB only (MEDIASUBTYPE_RGB32, FORMAT_VideoInfo), although you could easily modify it for other media types. |
