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 {VERSION} FLV muxer

enforce-increasing-timestamps 

“enforce-increasing-timestamps” gboolean

If set to true, flvmux will modify buffers timestamps to ensure they are always strictly increasing, inside one stream and also between the audio and video streams.

Flags : Read / Write

Default value : true

Since : 1.24

metadatacreator 

“metadatacreator” gchararray

The value of metadatacreator in the meta packet.

Flags : Read / Write

Default value : GStreamer {VERSION} FLV muxer

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

streamable 

“streamable” gboolean

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

Flags : Read / Write

Default value : false
