Hi all, I have a doubt regarding "autoplug-continue" signal of decodebin2. According to the <a href="http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gst-plugins-base-plugins/html/gst-plugins-base-plugins-decodebin2.html#GstDecodeBin2-autoplug-continue">documentation</a> "This signal is emitted whenever decodebin2 finds a new stream"; However when I am trying to open a mp3 file ( which has only one stream ) I am getting the callback at least 4 times, with the following caps: audio/mpeg, mpegversion=(int)1, layer=(int)3 audio/mpeg, mpegversion=(int)1, layer=(int)[ 1, 3 ], rate=(int)[ 8000, 48000 ], channels=(int)[ 1, 2 ], parsed=(boolean)true audio/mpeg, mpegversion=(int)1, mpegaudioversion=(int)1, layer=(int)3, rate=(int)44100, channels=(int)2, parsed=(boolean)true audio/mpeg, mpegversion=(int)1, layer=(int)[ 1, 3 ], rate=(int)[ 8000, 48000 ], channels=(int)[ 1, 2 ], parsed=(boolean)true Why is it so, I was expecting only one callback for the mp3 file, since its just a single stream. Thanks.
