IltmmDVDSource Interface
The IltmmDVDSource interface provides greater control than the DirectShow DVD Navigator when converting or playing a DVD image A set of files that contain all of the video and audio content for a DVD, organized with a table of contents (optional). See also: Title, Chapter The name for each individual video file on a DVD. For example, under the title "Water Skiing", you might have the chapters "My first try," "My first wreck," and "My first jump.", ISO Image An ISO image (.iso) is a disk image of a file system. It includes data files that are contained in the ISO image along with filesystem metadata. ISO images are an alternative to physical media for distribution of a "DVD" over the Internet. Most operating systems allow ISO images images to be "played" as if they were physical discs. See also: DVD Image... The DVD Navigator is the default filter used by the toolkit. It allows a user to playback the DVD normally with menus. However, it is not possible to individually select the DVD titles and chapters to be played. This is where the DVD Source filter is useful. It allows a user to predetermine which titles and chapters to play and convert. It then treats the entire playback like a normal file. No menus are presented. By default, the DVD Source filter will select the Main DVD title The name for a group of related video files (called "Chapters") on your DVD. For example, for a DVD called "My Summer Vacation," you might have the titles "Water Skiing," "New Friends," and "Hiking." For each of those titles, you might have one or more different video files. and default audio stream The portion of the file holding the audio data. The audio data might be compressed to save disk space. The data has to be decompressed using an audio decompressor oftware component which decompresses audio. It must be designed to work with ACM or DirectShow. Note that different compression methods require different decompressors. There is no universal decompressor capable of decoding all compressed streams. before you can play (hear) it.. This will work for most DVD’s. So the user doesn’t have to do anything.
The ltmmDVDSource Object can be accessed through the IltmmPlay and the IltmmConvert Interfaces. The put_UseDVDSource should be called with VARIANT_TRUE value before specifying the DVD source image to force the player and/or the converter to use the IltmmDVDSource interface when attempting to play or convert a DVD image. The IltmmDVDSource interface can be obtained by passing ltmmPlay_Object_SourceFilter or ltmmConvert_Object_SourceFilter as the ObjType parameter for IltmmPlay::GetSubObject or IltmmConvert::GetSubObject.
