GstValidate action types

description

description,
    [summary=(string)],
    [is-config=(boolean)],
    [handles-states=(boolean)],
    [seek=(boolean)],
    [reverse-playback=(boolean)],
    [need-clock-sync=(boolean)],

    [min-audio-track=(int)],
    [min-video-track=(int)],
    [duration=(double, int)],
    [pipeline-name=(string)];

Allows to describe the scenario in various ways

Implementer namespace: core
Is config action (meaning it will be executing right at the beginning of the execution of the pipeline)

Parameters

summary:(optional): Whether the scenario is a config only scenario (ie. explain what it does)

Possible types: string

Default: 'Nothing'
is-config:(optional): Whether the scenario is a config only scenario

Possible types: boolean

Default: false
handles-states:(optional): Whether the scenario handles pipeline state changes from the beginning in that case the application should not set the state of the pipeline to anything and the scenario action will be executed from the beginning

Possible types: boolean

Default: false
seek:(optional): Whether the scenario executes seek actions or not

Possible types: boolean

Default: false
reverse-playback:(optional): Whether the scenario plays the stream backward

Possible types: boolean

Default: false
need-clock-sync:(optional): Whether the scenario needs the execution to be synchronized with the pipeline's clock. Letting the user know if it can be used with a 'fakesink sync=false' sink

Possible types: boolean

Default: false
min-media-duration:(optional): Lets the user know the minimum duration of the stream for the scenario to be usable

Possible types: double

Possible types: int

Default: 0
min-video-track:(optional): Lets the user know the minimum number of video tracks the stream needs to contain for the scenario to be usable

Possible types: int

Default: 0
duration:(optional): Lets the user know the time the scenario needs to be fully executed

Possible types: double, int
