Merging of two audio aac files using gnonlin

[sumeeth kc]

Hi

I am trying to concatenate two aac files using this pipeline

gst-launch-0.10 gnlcomposition { gnlfilesource name="s1"
location="/home/sumeeth/Downloads/gstreamer-editing-services-0.10.0.2/audio1.aac"
start=0 duration=10000000000 media-start=0 media-duration=10000000000
gnlfilesource name="s2"
location="/home/sumeeth/Downloads/gstreamer-editing-services-0.10.0.2/audio2.aac"
start=0 duration=10000000000 media-start=30000000000
media-duration=10000000000 } ! ffenc_aac ! mp4mux ! filesink
location="merge.3gp"

I am getting this error -
