|

|
|
PJMEDIA Video Device API is a cross-platform video API appropriate for use with
|
||
|
|
VoIP applications and many other types of video streaming applications.
|
||
|
|
|
||
|
|
The API abstracts many different video API's on various platforms, such as:
|
||
|
|
- native Direct Show video for Win32 and Windows Mobile devices
|
||
|
|
- null-video implementation
|
||
|
|
- and more to be implemented in the future
|
||
|
|
|
||
|
|
The Video Device API/library is an evolution from PJMEDIA @ref PJMED_SND and
|
||
|
|
contains many enhancements:
|
||
|
|
|
||
|
|
- Forward compatibility:
|
||
|
|
\n
|
||
|
|
The new API has been designed to be extensible, it will support new API's as
|
||
|
|
well as new features that may be introduced in the future without breaking
|
||
|
|
compatibility with applications that use this API as well as compatibility
|
||
|
|
with existing device implementations.
|
||
|
|
|
||
|
|
- Device capabilities:
|
||
|
|
\n
|
||
|
|
At the heart of the API is device capabilities management, where all possible
|
||
|
|
video capabilities of video devices should be able to be handled in a generic
|
||
|
|
manner. With this framework, new capabilities that may be discovered in the
|
||
|
|
future can be handled in manner without breaking existing applications.
|
||
|
|
|
||
|
|
- Built-in features:
|
||
|
|
\n
|
||
|
|
The device capabilities framework enables applications to use and control
|
||
|
|
video features built-in in the device, such as:
|
||
|
|
- built-in formats,
|
||
|
|
- etc.
|
||
|
|
|
||
|
|
- Codec support:
|
||
|
|
\n
|
||
|
|
Some video devices support built-in hardware video codecs, and application
|
||
|
|
can use the video device in encoded mode to make use of these hardware
|
||
|
|
codecs.
|
||
|
|
|
||
|
|
- Multiple backends:
|
||
|
|
\n
|
||
|
|
The new API supports multiple video backends (called factories or drivers in
|
||
|
|
the code) to be active simultaneously, and video backends may be added or
|
||
|
|
removed during run-time.
