flvmux

flvmux muxes different streams into an FLV file.

Example launch line

 gst-launch-1.0 -v flvmux name=mux ! filesink location=test.flv  audiotestsrc samplesperbuffer=44100 num-buffers=10 ! faac ! mux.  videotestsrc num-buffers=250 ! video/x-raw,framerate=25/1 ! x264enc ! mux.

This pipeline encodes a test audio and video stream and muxes both into an FLV file.

Properties

encoder

“encoder” gchararray

The value of encoder in the meta packet.

Flags : Read / Write

Default value : GStreamer 1.17.1 FLV muxer


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


metadatacreator

“metadatacreator” gchararray

The value of metadatacreator in the meta packet.

Flags : Read / Write

Default value : GStreamer 1.17.1 FLV muxer


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


skip-backwards-streams

“skip-backwards-streams” gboolean

If set to true, streams that go backwards related to the other stream will have buffers dropped until they reach the correct timestamp

Flags : Read / Write

Default value : false


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)


streamable

“streamable” gboolean

If True, the output will be streaming friendly. (ie without indexes and duration)

Flags : Read / Write

Default value : false
