interleave

interleave — Folds many mono channels into one interleaved audio stream

Synopsis

                    GstInterleave;

Description

Merges separate mono inputs into one interleaved stream.

This element handles all raw floating point sample formats and all signed integer sample formats. The first caps on one of the sinkpads will set the caps of the output so usually an audioconvert element should be placed before every sinkpad of interleave.

It's possible to change the number of channels while the pipeline is running by adding or removing some of the request pads but this will change the caps of the output buffers. Changing the input caps is _not_ supported yet.

The channel number of every sinkpad in the out can be retrieved from the "channel" property of the pad.

Example launch line

gst-launch-0.10 filesrc location=file.mp3 ! decodebin ! audioconvert ! "audio/x-raw-int,channels=2" ! deinterleave name=d  interleave name=i ! audioconvert ! wavenc ! filesink location=test.wav    d.src0 ! queue ! audioconvert ! i.sink1    d.src1 ! queue ! audioconvert ! i.sink0
Decodes and deinterleaves a Stereo MP3 file into separate channels and then interleaves the channels again to a WAV file with the channel with the channels exchanged.
gst-launch-0.10 interleave name=i ! audioconvert ! wavenc ! filesink location=file.wav  filesrc location=file1.wav ! decodebin ! audioconvert ! "audio/x-raw-int,channels=1" ! queue ! i.sink0   filesrc location=file2.wav ! decodebin ! audioconvert ! "audio/x-raw-int,channels=1" ! queue ! i.sink1
Interleaves two Mono WAV files to a single Stereo WAV file.
