![]() ![]() This means that for you to play DVD on Windows Media Player you will have to convert DVD to Windows Media Player supported format for instance (WMV, WMA and AVI). However, the truth is that Windows Media Player only supports the default video format. Sometimes you might find it difficult to play video Windows Media Player without understanding the reason behind it. On the other hand, it is easier to solve problems associated with missing DVD decoders. What one needs is a DVD drive and a compatible DVD decoder installed on their laptop or computer. One major reason why many people play DVD with Windows Media Player is because of compatibility issues when it comes to decoders. On the other hand, you can also play video CDs (VCDs) which are similar to DVDs despite having a low quality video as compared to DVD. With Windows Media Player you will be able to play a variety of audio CDs, data CDs, in addition to data DVDs that contain music or video files. Windows Media Player has had a good tiding with other formats a reason why many individuals would want to play DVD with Windows Media Player. The key exchange sequence is implemented through properties sent to the DVD decoder minidriver's input pins.Play DVD with Windows Media Player has always been fun and much easier. Microsoft supports both software and hardware decrypters by way of the DVD navigator/splitter, which oversees the authentication sequence between the decoders and the DVD-ROM drives in a computer. For software decoders, the accelerated graphics port (AGP) bus can be used to transfer the decoded video to the VGA.Ĭopyright protection for DVD is provided by encrypting sectors on a disc and then decrypting those sectors before decoding them. Microsoft provides software support for these interfaces by using the DirectDraw hardware abstraction layer (HAL) with video port extensions (VPE) to pass video that was decoded in hardware to the video graphics array (VGA). These filters enable playback of video using hardware video ports, and provide support for blending low-bandwidth video streams, such as the closed caption decoder output stream.ĭedicated buses transfer decoded video streams from an MPEG-2 decoder to the display card. This filter converts closed-caption data in a DVD video stream into text images.ĭirectShow Video Port Manager and Rendering Filters This filter supports plug-ins that allow expansion for new interfaces.ĭirectShow Closed-Caption Decoding Filter It creates (that is, instantiates) a device object for each data type to be decoded in hardware, such as audio and video data types. This filter converts DirectShow interfaces to WDM connection and streaming architecture properties. The filter responds to commands in the stream and handles all user input. This filter reads the DVD stream directly from a DVD disc and produces individual media type outputs, such as audio, video, and subpicture. The DVD navigator/splitter filter interprets the programming language embedded in DVD movies, parental control, multiple languages, and processes most DVD-specific data structures. This installable file system supports UDF-formatted DVD discs.ĭirectShow filters and related support include a DVD navigator/splitter, proxy filters for interfacing with the hardware decoder minidrivers for video, subpicture and audio streams, line21 decoder (closed caption), a video mixer, video renderer, and an audio renderer. NT-based operating systems provide a UDF-installable file system, similar to FAT and NTFS. This class driver provides the ability to read data sectors from a DVD-ROM drive. Support for the DVD-ROM command set, including commands for copyright protection and regionalization, is provided in Windows XP by an updated CD-ROM class driver. Vendors must supply either a DirectShow-compatible software decoder for each required DVD data stream, or provide a WDM streaming-compatible DVD decoder minidriver to support their DVD hardware decoders. Microsoft does not provide MPEG-2 or AC-3 software/hardware decoder filters with Windows XP. ![]()
