PySide6.QtMultimedia.QPlaybackOptions¶

class QPlaybackOptions¶

The QPlaybackOptions class enables low-level control of media playback options.

Details

QPlaybackOptions gives low-level control of media playback options. Although we strongly recommend to rely on the default settings of QMediaPlayer , QPlaybackOptions can be used to optimize media playback to specific use cases where the default options are not ideal.

Note that options are hints to the media backend, and may be ignored if they are not supported by the current media format or codec.

Playback options rely on support in the media backend. Availability is documented per option.

Added in version 6.10.

class PlaybackIntent¶

Configures the intent of media playback, to focus on either high quality playback or low latency media streaming.

Constant

Description

QPlaybackOptions.PlaybackIntent.PlaybackIntent.Playback

The intent is robust and high quality media playback, enabling sufficient buffering to prevent glitches during playback.

QPlaybackOptions.PlaybackIntent.PlaybackIntent.LowLatencyStreaming

Buffering is reduced to optimize for low latency streaming, but with a higher likelihood of lost frames or other glitches during playback.

Constant	Description
QPlaybackOptions.PlaybackIntent.PlaybackIntent.Playback	The intent is robust and high quality media playback, enabling sufficient buffering to prevent glitches during playback.
QPlaybackOptions.PlaybackIntent.PlaybackIntent.LowLatencyStreaming	Buffering is reduced to optimize for low latency streaming, but with a higher likelihood of lost frames or other glitches during playback.

Note

Properties can be used directly when from __feature__ import true_property is used or via accessor functions otherwise.

property networkTimeoutᅟ: std::chrono::milliseconds¶

Determines the network timeout used for socket I/O operations with some network formats.

This option is only supported with the FFmpeg media backend.

Access functions:

networkTimeout()
setNetworkTimeout()
resetNetworkTimeout()

property playbackIntentᅟ: QPlaybackOptions.PlaybackIntent¶

Determines if QMediaPlayer should optimize for robust high quality video playback (default), or low latency streaming.

This option is only supported with the FFmpeg media backend.

Access functions:

playbackIntent()
setPlaybackIntent()
resetPlaybackIntent()

property probeSizeᅟ: int¶

Probesize defines the amount of data (in bytes) to analyze in order to gather stream information before media playback starts.

A larger probesize value can give more robust playback but may increase latency. Conversely, a smaller probesize can reduce latency but might miss some stream details. The default probesize is -1, and the actual probesize is determined by the media backend.

This option is only supported with the FFmpeg media backend.

Access functions:

probeSize()
setProbeSize()
resetProbeSize()
