QMediaResource

PyQt5.QtMultimedia.QMediaResource

Description

The QMediaResource class provides a description of a media resource.

A media resource is composed of a url() containing 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. QMediaResource includes information such as the mimeType(), audioCodec() and videoCodec() codecs, audioBitRate() and videoBitRate() bit rates, and resolution() so these constraints and others can be evaluated.

The only mandatory property of a QMediaResource is the url().

Methods

__init__()

Constructs a null media resource.

---

__init__(QMediaResource)

Constructs a copy of a media resource other.

---

__init__(QUrl, mimeType: str = '')

Constructs a media resource with the given mimeType from a url.

---

__init__(QNetworkRequest, mimeType: str = '')

Constructs a media resource with the given mimeType from a network request.

---

audioBitRate() → int

Returns the bit rate in bits per second of a media resource’s audio stream.

This may be zero if the bit rate is unknown, or the resource contains no audio stream.

setAudioBitRate().

---

audioCodec() → str

Returns the audio codec of a media resource.

This may be null if the media resource does not contain an audio stream, or the codec is unknown.

See also

setAudioCodec().

---

channelCount() → int

Returns the number of audio channels in a media resource.

This may be zero if the sample size is unknown, or the resource contains no audio stream.

See also

setChannelCount().
