Public bug reported:

mplayer spuriously skips ahead while listening to network stream.

the skips i have observed are small skips, a portion of a word will be
missing, or the music will skip ahead by half a beat.  many of the skips
escape the notice of my ears.  if i carefully watch the mplayer timer
last figure, the percentage (of the buffer that's filled?), usually it
bounces around only by 3 or 4% at most, but occasionally it drops by 5
or 10% and does not recover, bouncing around the new lower value for an
unpredictable period of time, then drops again.  after this happens a
number of times, the percentage reaches 0%, it prints "Cache empty,
consider increasing -cache and/or -cache-min. [performance issue]", the
sound drops for a second or two, and resumes, with the percentage
recovered only a small amount, such that it very quickly hits zero
again, and keeps printing the message repeatedly each accompanied by a 1
or 2 second gap in sound.  if i stop mplayer and restart it, the
percentage is higher for awhile, until it eventually drops to zero
again, where as before it prints the message repeatedly each accompanied
by a 1 or 2 second gap in the sound.  i do not know the circumstances
that cause this.  i can listen for hours without it happening sometimes,
while other times even though i repeatedly exit and restart mplayer it
quickly happens again.  so it's tempting to guess it may be related to
network traffic.  even if that's true, the bug would then be lack of
ability to recover sensibly on the fly.
