Detailed Description¶
A media resource is composed of a
URLcontaining the location of the resource and a set of properties that describe the format of the resource. The properties provide a means to assess a resource without first attempting to load it, and in situations where media be represented by multiple alternative representations provide a means to select the appropriate resource.Media made available by a remote services can often be available in multiple encodings or quality levels, this allows a client to select an appropriate resource based on considerations such as codecs supported, network bandwidth, and display constraints.
QMediaResourceincludes information such as theMIME type,audioandvideocodecs,audioandvideobit rates, andresolutionso these constraints and others can be evaluated.The only mandatory property of a
QMediaResourceis theurl().See also

This may be null if the MIME type is unknown.
- PySide2.QtMultimedia.QMediaResource.__ne__(other)¶
- Parameters:
- Return type:
bool
Compares a media resource to
other.Returns true if they are different, and false otherwise.
- PySide2.QtMultimedia.QMediaResource.__eq__(other)¶
- Parameters:
- Return type:
bool
Compares a media resource to
other.Returns true if the resources are identical, and false otherwise.

- Return type:
Returns the network request associated with this media resource.
- PySide2.QtMultimedia.QMediaResource.resolution()¶
- Return type:
Returns the resolution in pixels of a media resource.
This may be null is the resolution is unknown, or the resource contains no pixel data (i.e. the resource is an audio stream.
See also
