When playing back an rtsp stream with playbin2, the audio is stuttery. I have
provided the output from: rtspsrc .... ! application/x-rtp, media=audio !
gdppay ! filesink location=~/stuttry_rtsp.gdp
The file is here: http://dl.dropbox.com/u/219349/stuttry_rtsp.gdp
gst-launch filesrc location=stuttry_rtsp.gdp ! gdpdepay ! decodebin2 ! identity
check-imperfect-timestamp=true ! fakesink -m provides lots of imperfect
timestamp messages for example:
Got message #1106 from element "identity0" (element): imperfect-timestamp,
prev-timestamp=(guint64)90480001625, prev-duration=(guint64)21333333,
