Description Adrian Wilkins 2010-12-10 11:39:16 UTC 
Enlosed file stutters a great deal when played back using gstreamer based tools 

e.g.

gst-launch-0.10 playbin2 "uri=file://`pwd`/01 - AIF.wma"

Having seen https://bugzilla.gnome.org/show_bug.cgi?id=610143 , also tried

gst-launch-0.10 playbin2 "uri=file://`pwd`/01 - AIF.wma"  \
    audio-sync='pulsesink drift-tolerance=150000'

This made no difference.

mplayer (1.0rc4-4.4.5) plays this file back without stuttering, but vlc (1.1.4) exhibits a different stuttering pattern to gstreamer player (e.g. Rhythmbox, Totem).

I have lots of audio files that exhibit this pattern, mostly encoded on Windows using the default low-bitrate WMA that Windows Media Player or Winamp was configured to use by default around 2005 (unless you paid to unlock higher bitrates and other encoders).

File is at

As it exceeds the attachment limit.

Increasing drift-tolerance makes (quite) a difference (note: not sync-tolerance), as far as I can hear.  It's still not perfect, since some glitches exceed that particular tolerance.

All in all, looks like https://bugzilla.gnome.org/show_bug.cgi?id=610143 after all.

Btw, never mind the bit about sync-tolerance ...
