Crash on pyglet.media.Player.play() after calling seek() on video files

[GoogleCodeExporter]

The following test causes causes the crash for me.

import pyglet
#i've only been able to reproduce when using openal
pyglet.options["audio"] = ('openal',)

#load a video file into a Player
playerVideo = pyglet.media.Player()
playerVideo.queue( pyglet.media.load("assets/test_vid.mpg") )

#if you seek() before playing, pyglet will attempt to allocate an absurd
amount of memory
#and eventually crash
playerVideo.seek(.5)
playerVideo.play()

Paste in the traceback or error message:

Any additional info (platform/language/hardware) that may be relevant?

I've also seen this bug occur on Windows when using OpenAL. I've also
triggered it using both a .flv and .mpg file. I've been able to reproduce
with both 1.1.2 and 1.1.3.

No crash on OS X with 1.1.3, AVbin 5.

I'm pretty sure the bug described by pyalot is an unrelated issue (occurs on 
OSX with 1.2dev, fixed in r2462).

Now when seeking no video is being played (black display). Commenting out the 
seek,
the video plays.

Addition, 5 years later

Description:
After calling .seek() on a video file (mpeg4) the application crashes with 
SIGSEGV (Address boundary error).

Code:
fname = '/full_path/asdf.mp4'
offset = 74.0
video_src = pig.media.load(video_fname)
player = pig.media.Player()
player.queue(video_src)
player.seek(offset)
player.play()

Without the seek the video plays normally (although without sound, but it's not 
important for this bug).

System:
Ubuntu 14.04 x86_64
Python 2.7.6
Pyglet 1.1.4 (via Ubuntu's synaptic distribution)
