Summary: Using avdec_mp3 decoder appliction can't retrieve the
audio codec info.
Classification: Platform
Product: GStreamer
Version: 1.0.5
OS/Version: Linux
Status: UNCONFIRMED
Severity: normal

GNOME version: ---
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.
