Description Haijiao Qiao 2013-04-18 06:37:11 UTC 
Using gst-launch-1.0 playbin uri=file:///*.mp3 -t and avdec_mp3 decoder, application can't retrieve codec info. The reason is mpegaudioparse plugin only send TAG_EVENT once to downstream, avdec_mp3 recieved and then send to decodebin. But by now expose_pad function in decodebin hasn't been invoked. So this tag event dropped.  Using mad decoder, the problem cann't reproduced. The reason is GstAudioDecoder will sent the TAG_EVENT again. Please confirmed.
