MPEG-1/MPEG-2
Codec Package
Rovi's MainConcept MPEG-1/2 Codec Package enables applications to read, write and edit MPEG-1 and MPEG-2 streams in high quality with sensational speed. The SDK is ideal for consumer-level products and broadcast usage.
The encoder is full featured, and it is possible to have access to nearly every MPEG setting imaginable. It also includes pre-configured templates for VCD, SVCD, DVD, MICROMV, HDV, CableLabs, XDCAM HD, XDCAM EX, Blu-ray and other standards.
The MPEG-1/2 Video Encoder meets the highest broadcast quality standards and includes professional features like transport streams, 4:2:2 support, 2-pass encoding and more. However, the SDK is so flexible that it can also be used to capture analog or DV material in real-time to MPEG.
The MPEG-1/2 Video Decoder can process MPEG video streams produced by the MainConcept MPEG-2 Demultiplexer or by any other compliant filter, such as Microsoft MPEG-2 Splitter, MPEG-2 Demultiplexer or MPEG-1 Stream Splitter. DirectShow filters provide additional stream handling, such as reading from a file or network source and rendering it to a window or DirectDraw® surface. The filter can process Closed Captions (CC) and has a CC output pin. The CC data output is executed in a way suitable for decoding by the software Line 21 decoder filter which comes with DirectShow.
For Windows, Mac OS X and Linux, the codec package consists of a Low Level API (in the C programming language). Under Windows, it additionally includes DirectShow® filters for decoding and encoding MPEG-1/MPEG-2 frames. The decoder filter can be used by any DirectShow application (e.g. Windows® Media Player).
The Codec Package is available as 32-bit as well as 64-bit version for Windows, Mac OS X and Linux.
With MainConcept Reference, the professional transcoder application by MainConcept, MPEG-1/2 is also available for seamless codec conversion from and to various formats. Click here for details.
The above codec is also available within MainConcept™ ShowCase, providing simple and seamless decoder access via DirectShow filters (for Microsoft operating systems). MainConcept ShowCase frees developers from integrating MainConcept Codec SDK decoding components into their own development for just testing the features, performance and quality.
