Bug ID: 90515 Summary: memory use increase with vdpau Product: Mesa Version: 10.4 Hardware: Other OS: All Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/radeonsi Assignee: dri-devel@lists.freedesktop.org Reporter: fabrice@bellet.info QA Contact: dri-devel@lists.freedesktop.org
I noticed a constant increase of rss memory while playing a video using vdpau + radeonsi, caused by X events accumulating in read_packet (c=0x8275a0) at xcb_in.c:333, and never flushed, and corresponding to this backtrace :

The commands generating this case is :
# ln -s vdpau_drv_video.so /usr/lib64/dri/radeonsi_drv_video.so $ export VDPAU_DRIVER=radeonsi $ wget http://samples.mplayerhq.hu/MPEG-4/NeroRecodeSample-MP4/NeroRecodeSample.mp4 $ gst-launch-1.0 filesrc location=NeroRecodeSample.mp4 ! qtdemux ! mpeg4videoparse ! vaapidecode ! videoconvert ! glimagesink
The two malloc() occuring in libxcb in read_packet() are sufficient to make gst-launch-1.0 memory use grow out of control. It seems to occur because vl_dri2_set_drawable() is called alternatively with two different drawables, each call destroying the previous drawable.
