Re: Syncing Audio w/ Video problems

[Blaine Booher]

I'm just curious: Has anyone else synced audio and video without problems in pyglet?

Hi guys. I'm using cocos2d's director for displaying 2D scenes. It's just a thin wrapper around all the pyglet library routines.

I'm trying to play a video, and it works great except for the fact that the audio is not synced with the video. The audio appears to start about a quarter second early. Any ideas on what I'm doing wrong?

My video layer basically looks something like this:

class VideoLayer(cocos.layer.Layer):

def __init__(self, video_path):

'''

<image> is a loaded pyglet compatible image

'''

super(VideoLayer, self).__init__()

self.video_path = video_path

def on_enter(self):

player = pyglet.media.Player()

player.eos_action = player.EOS_LOOP # Could also be EOS_PAUSE or EOS_NEXT

self.video = pyglet.media.load(self.video_path)

player.queue(self.video)

player.play()

self.player = player

def draw(self):

if self.player.playing:

self.player.get_texture().blit(0,0)

draw() is called just like the on_draw() event, on_enter() is only called when the layer is viewed. 

I like I said, it looks great and the audio isn't choppy, it's just not in sync w/ the video.

What version of Pyglet, AVbin, and OS are you using?  What is the video format?  Can you share the video file?
