glmosaic

glmixer sub element. N gl sink pads to 1 source pad. N + 1 OpenGL contexts shared together. N <= 6 because the rendering is more a like a cube than a mosaic Each opengl input stream is rendered on a cube face

Properties

context

“context” GstGLContext *

Get OpenGL context

Flags : Read


latency

“latency” guint64

Additional latency in live mode to allow upstream to take longer to produce buffers for the current position (in nanoseconds)

Flags : Read / Write

Default value : 0


min-upstream-latency

“min-upstream-latency” guint64

When sources with a higher latency are expected to be plugged in dynamically after the aggregator has started playing, this allows overriding the minimum latency reported by the initial source(s). This is only taken into account when larger than the actually reported minimum latency. (nanoseconds)

Flags : Read / Write

Default value : 0


start-time

“start-time” guint64

Start time to use if start-time-selection=set

Flags : Read / Write

Default value : 18446744073709551615


start-time-selection

“start-time-selection” GstAggregatorStartTimeSelection *

Decides which start time is output

Flags : Read / Write

Default value : zero (0)
