Hi,<br><br>Right now I can't test your exact example on linux I guess ?<br><br>But I have tested this one on Windows with no problems:<br><br>--------------------------------<br>import gobject<br>import pygst<br>pygst.require("0.10")<br>

<br>gobject.MainLoop().run()<br>--------------------------------<br><br>What's the exact version of your gstreamer (core/base/gl/python) ? Are you building it from git or ?<br><br>Julien<br><br><br><div class="gmail_quote">

Hello,<br>
<br>
Consider following Python code, which creates four simple pipelines at<br>
the same time:<br>
<br>
import wx<br>
import pygst<br>
pygst.require("0.10")<br>
import gst<br>
<br>
players = []<br>
for i in range(4):<br>
players.append(gst.parse_launch("videotestsrc ! glimagesink"))<br>
<br>
for player in players:<br>
player.set_state(gst.STATE_PLAYING)<br>
<br>
app = wx.App(redirect=False)<br>
frame = wx.Frame(None)<br>
frame.Show()<br>
app.MainLoop()<br>
<br>
This code crashes a lot with various errors:<br>
- 0xc0000005 exceptions<br>
- fatal flex scanner internal error--end of buffer missed<br>
- (python.exe:2788): GstGLShader-WARNING **: Fragment Shader<br>
compilation failed: ERROR: 0:1: 'float' : syntax error parse error<br>
<br>
Sometimes, however, it runs OK.<br>
<br>
To me it looks like some bug in glimagesink having something to do<br>
with thread safety. Anyone have any ideas what might be the cause of<br>
this strange behaviour and how to get rid of it?<br>
<br>
