ffmpegcolorspace: Fix invalid memory accesses with odd widths/heights during subsampling (11.36 KB, patch)
2010-07-02 12:00 UTC, Sebastian Dröge (slomo) 		committed Details | Review

Description Sebastian Dröge (slomo) 2010-07-02 11:59:45 UTC 
ffmpegcolorspace has some invalid memory accesses with odd widths/heights during the subsampling process, e.g. when converting planar 4:2:2 to 4:4:4.

Example pipeline:
GST_REGISTRY_UPDATE=no G_SLICE=always-malloc valgrind --track-origins=yes ../../../gstreamer/tools/.libs/gst-launch-0.10 videotestsrc num-buffers=1 ! "video/x-raw-yuv,format=(fourcc)YUY2,width=320,height=241" ! ffmpegcolorspace ! "video/x-raw-yuv,format=(fourcc)YV12" ! fakesink


This happens in the videoscale unit test too.
