openmptdec

openmpdec decodes module music formats, such as S3M, MOD, XM, IT. It uses the OpenMPT library for this purpose. It can be autoplugged and therefore works with decodebin.

Example launch line

 gst-launch-1.0 filesrc location=media/example.it ! openmptdec ! audioconvert ! audioresample ! autoaudiosink
