◆ createMediaSocket() [3/3]

primo::avblocks::MediaSocket * createMediaSocket ( MediaInfo * mediaInfo )

Creates a media socket from a MediaInfo object.

This method will call MediaInfo::load, if the MediaInfo has not been loaded.

Parameters

mediaInfo [in] A pointer to a MediaInfo object with audio/video information. This object is not needed after the method returns.

Returns: A pointer to a new MediaSocket object.
The pointer to a new MediaSocket object contains the information supplied by the mediaInfo parameter.
The caller is responsible for releasing the returned media socket when it is not needed anymore.; NULL if there was an error. In this case call MediaInfo::error() for detailed error information.

This method is meant to help in setting correctly the inputs of the Transcoder. The intended usage is as follows:

Use MediaInfo to load information for a file or user stream.
Create a media socket from the MediaInfo object (Library::createMediaSocket(MediaInfo*)).
Add the newly created socket to the inputs of the Transcoder (Transcoder::inputs(), MediaSocketList::add()).
Release the media socket if it will not be used outside of the Transcoder.
