[maemo-developers] GStreamer xvimagesink performance issue

[From: David Festacho]

Hi all,

I am working on a gstremaer project which implies the modification of the xvimagesink module (part of the base plugins). Even before introducing any change in the code, I am getting worse performance with my compiled code compared to the original binary found in my N810.

This is a brief summary of the issue.

I got source code from GStreamer project site:

http://gstreamer.freedesktop.org/src/gst-plugins-base/gst-plugins-base-0.10.13.tar.gz

This is version 0.10.13 of base plugin package (the same version as the binary found in my N810, OS 2008).

I am using Scratchbox with the CHINOOK_ARMEL (cs2005q3.2-glibc2.5-arm) toolchain.

I use the provided autogen.sh script to generate the build system files.
Then, I use the configure script (without any extra parameter) to generate Makefiles.

After 'make' I get 'libgstxvimagesink.so'.

The performance of this newly created binary is significantly worse to the original binary. When using the default media player (which uses xvimagesink), motion shows jerkiness.


Is there any N810 specific patch that needs to be applied to source code or any specific configure parameters that need to be used in order to get the very same original binary (or at least one that performs similarly?

Best regards,

  David
