AVStream Driver Reference Information

and rate, color formats, or crop settings. The driver color converts and copies video as required to deliver up to 25 or 29.97 frames per second in any format to the two pins.

∙With SimulStream enabled, there can be multiple capture pins and multiple preview pins. Each capture and preview pin pair is placed on a separate filter. The maximum number of each type of pin is the same as the maximum number of filters you have elected to expose in the SimulStream control group. Any pin can produce video at any size, rate, color format, and crop setting. Of course, practical limits are imposed by the bandwidth of the machine.

∙The following post-processing filters can be applied, with or without SimulStream enabled:

∙Motion adaptive deinterlacing and inverse telecine

∙Gamma correction

∙Logos

∙On-video caption rendering

Some of these filters operate globally on all filters and pins of a device, and some operate on a per- filter or per-pin basis:

∙The Video Proc Amp controls – brightness, contrast, hue, saturation, and sharpness – are applied globally in hardware to the incoming video.

∙The basic reference size – CCIR–601 or square pixel – is established in hardware. Horizontal delay is also performed in hardware.

Deinterlace / inverse telecine and gamma correction are applied to all filters and pins on the device and have the same settings for all filters and pins. (Adaptive deinterlacing does not affect quality of single field 2:1 or 4:1 exact-scaled video, so long as the “sharp” algorithm is used. Inverse telecine does not affect single field exact-scaled video.)

Crop, logo, and caption settings can be different for each pin of each filter, and the driver maintains separate settings for each filter and pin.

Video size, color format, and frame rate can also be different for each pin. It is the responsibility of the application to maintain these settings.
