           Summary: choppy sound after vorbisenc
    Classification: Desktop
           Product: GStreamer
           Version: git
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal

After encoding or recoding some sources i get choppy sound if i use vorbisenc,
if i use flacenc i get warnings about wrong timestamps and suggestion to use
audiorate. If i do not use audiorate with flaenc i get good sound. If i use
audiorate with flacenc i get same kind of choppy sound like with vorbisenc.

I assume vorbisenc has some kind of build in timestampcorrection/audiorate.

Here is the pipeline i use to recode:
gst-launch -e oggmux name=mux ! filesink location=tmp.ogg filesrc
location=1888-de_1.10-wilhelm_und_die_welt.asf ! asfdemux name=demux
demux.audio_00 ! ffdec_wmav2 ! audioconvert ! audiorate ! vorbisenc ! mux.

in other hand ffdec_wmav2 may produce wrong timestamps.

The video to reproduce you can find here:

i use mplayer to dump this stream:
mplayer -dumpstream -playlist
