@head3 Introduction |
|
|
|
|
The vcmStreamXXX APIs are defined to simplify integration of video
|
|
compression and decompression in NetMeeting's datapump. Currently, the datapump
|
|
behavior relies a lot on the acmStreamXXX APIs. In order to limit the amount of modifications that need to be applied
|
|
to the datapump, we define video compression APIs with a behavior similar to
|
|
the audio compression APIs. Integration in the datapump will be achieved by defining
|
|
a FilterVideoManager class identical to the FilterManager class, where calls to
|
|
acmStreamXXX functions are simply replaced by calls to vcmStreamXXX functions.

// HVCMDRIVER: used to manage a driver (codec, filter, etc). this handle

// HVCMSTREAM: used to manage a 'stream' (conversion channel) with the
|
|
// VCM. you use a stream handle to convert data from one format/type
|
|
// to another--much like dealing with a file handle.
|

*
|
|
* @field PBYTE | pbPrev | Specifies a pointer to the previous destination data
|
|
* buffer. This pointer must always refer to the same location while
|
|
* the stream header remains prepared. If an application needs to change
|
|
* the destination location, it must unprepare the header and re-prepare
|
|
* it with the alternate location.
|
|
*
|
|
* @field DWORD | cbPrevLength | Specifies the length, in bytes, of the previous
|
|
* destination data buffer pointed to by <e VCMSTREAMHEADER.pbPrev>.
|
|
* When the header is prepared, this member must specify the maximum
|
|
* size that will be used in the destination buffer. Conversions can be
|
|
* performed to destination lengths less than or equal to the original
|
|
* prepared size. However, this member must be reset to the original
|
|
* size when unpreparing the header.
|
|
*
|
|
* @field DWORD | cbPrevLengthUsed | Specifies the amount of data, in bytes,
|
|
* returned by a conversion. This member is not valid until the
|
|
* conversion is complete. Note that this value may be less than or
|
|
* equal to <e VCMSTREAMHEADER.cbPrevLength>. An application must use
|
|
* the <e VCMSTREAMHEADER.cbPrevLengthUsed> member when advancing to
|
|
* the next destination location for the conversion stream.
|
|
*
|
|
* @field DWORD | dwDstUser | Specifies 32 bits of user data. This can be
|
|
* any instance data specified by the application.
|
|
*
|
|
* @field struct tVCMSTREAMHEADER * | lpNext | Reserved for driver use and should not be
|
|
* used. Typically, this maintains a linked list of buffers in the queue.
|
|
*
|
|
* @field DWORD | reserved | Reserved for driver use and should not be used.
|
|
*
|
|
* @type PVCMSTREAMHEADER | Pointer to a <t VCMSTREAMHEADER> structure.
|
|
*
|
|
* @comm Before an <t VCMSTREAMHEADER> structure can be used for a conversion, it must
|
|
* be prepared with <f vcmStreamPrepareHeader>. When an application
|
|
* is finished with an <t VCMSTREAMHEADER> structure, the <f vcmStreamUnprepareHeader>
|
|
* function must be called before freeing the source and destination buffers.
