GStreamer | gst-ffmpeg | Ver: HEAD CVS
Summary: performance issue in gstffmpeg
Product: GStreamer
Version: HEAD CVS
Platform: Other
OS/Version: All
Status: UNCONFIRMED
Severity: normal
Priority: Normal
Component: gst-ffmpeg
AssignedTo: gstreamer-bugs at lists.sourceforge.net
ReportedBy: brian.cameron at sun.com
QAContact: gstreamer-bugs at lists.sourceforge.net
GNOME version: Unspecified
GNOME milestone: Unspecified
I run totem and play an ogg video, and notice the following performance report
using the Sun Studio compiler performance tool:
This is running a 43.49 second test:
- 8.666 seconds - resample_linear_argb_ref in liboil
- 6.545 seconds - yuv420p_to_argb32 in gstffmpegcolorspace
- 6.044 seconds - merge_linear_argb_ref in liboil
Note the #2 function is a gstffmpegcolorspace function. It seems it would be
good to make this function make use of hardware acceleration.
