# 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.
