[gst-devel] gst-plugins-gl

[Alex Ugarte]

Hi,
today I have downloaded and compiled the opengl plugins from the git
repository in a PC with Debian Lenny and it worked Ok.
This evening I have tried to do the same process in another computer, also
with Debian Lenny, but in this case for AMD64 architecture. In this case,
when executing a test pipeline or the cube test application, I get a
segmentation fault. I cannot assure 100% that both systems are equal (but
for that little detail of the number of bits), but I have installed them
both in the las two days, and more or less with the same packages.

These are the test pipelines I hav tried:
gst-launch-0.10  --gst-debug=glupload:5 --gst-debug=gldisplay:5
videotestsrc !  glupload ! fakesink
gst-launch-0.10  --gst-debug=glupload:5 --gst-debug=gldisplay:5
videotestsrc !  glimagesink

(At the end of the mail the log output).

I have been looking into the code and the segmentation fault happens in
gstdisplay.c, in method gst_gl_display_init_upload, which is called from
gst_gl_upload_set_caps and in gst_glimage_sink_render. More exactely the
SIGSEGV happens when calling gst_gl_window_send_message.

Has anyone managed to use the opengl plugins in an amd64 system?


Thanks and great job these plugins (and gstreamer in general).

Alex
