DirectShow filter for real-time mixing of video streams, pictures and texts
Overview
Mixer designed for mixing multiple video streams, as well as overlay pictures, subtitles, texts (including date, time, frame number, and so on). It allows you to dynamically change the size, location and transparency of elements in the output stream.
Features
- Supports mixing for video in different formats and with different FPS
- Supports overlay images of various types, including BMP, PNG, JPEG, etc.
- Supports overlay of plain texts, date, time, frame number, SMPTE timecode.
- Supports connect to Microsoft Line 21 Decoder to output closed captions.
- Supports moving, resizing, rotation, alpha blending and color keying of image elements.
Supported Uncompressed video Formats
- MEDIASUBTYPE_YUV2,
- MEDIASUBTYPE_UYVY,
- MEDIASUBTYPE_NV12,
- MEDIASUBTYPE_YV12.
- MEDIASUBTYPE_I420.
- MEDIASUBTYPE_RGB32,
- MEDIASUBTYPE_RGB24,
- MEDIASUBTYPE_ARGB32,
- MEDIASUBTYPE_RGB555,
- MEDIASUBTYPE_RGB565,
- MEDIASUBTYPE_r210,
- MEDIASUBTYPE_v210
Supported Image File formats
- BMP (BMP file format/Windows bitmap)
- JPEG (Joint Photographic Experts Group)
- TIFF (Tagged Image File Format)
- GIF (Graphics Interchange Format)
- PNG (Portable Network Graphics)
- ICO (Windows icons)
Supported Resizing Algorithms
- Nearest neighbor interpolation. Filter size is 1x1.
- Linear interpolation. Filter size is 2x2. Antialiasing feature possible.
- Interpolation with two-parameter cubic filter: B-spline (B=1, C=0). Filter size is 4x4. Antialiasing feature possible.
- Interpolation with two-parameter cubic filter: Catmull-Rom spline (B=0, C=1/2). Filter size is 4x4. Antialiasing feature possible.
- Interpolation with two-parameter cubic filter: special window (B=1/2, C=3/10). Filter size is 4x4. Antialiasing feature possible.
- Interpolation with 2-lobed Lanczos window function. Filter size is 4x4. Antialiasing feature possible.
- Interpolation with 3-lobed Lanczos window function. Filter size is 6x6. Antialiasing feature possible.
- Supersampling interpolation. It can be used only for reducing image size by the both dimensions.
