Description Thomas Vander Stichele 2005-04-12 10:35:10 UTC 
this launch line shows a green line being added:

gst-launch -v videotestsrc !
video/x-raw-yuv,width=720,height=576,format=\(fourcc\)YUY2,framerate=25.0 !
videoscale ! video/x-raw-yuv,width=263,height=192 ! ffmpegcolorspace ! videobox
right=-1 ! xvimagesink

this one shows a black border being added
gst-launch -v videotestsrc !
video/x-raw-yuv,width=720,height=576,format=\(fourcc\)YUY2,framerate=25.0 !
videoscale ! video/x-raw-yuv,width=263,height=192 ! ffmpegcolorspace ! videobox
right=-2 ! xvimagesink
Comment 1 Thomas Vander Stichele 2005-04-13 10:27:07 UTC 
some more pipelines, this time for I420:

gst-launch -v videotestsrc !
video/x-raw-yuv,format=\(fourcc\)I420,width=324,height=240,framerate=5.0 !
videobox right=-2 ! xvimagesink

is ok

gst-launch -v videotestsrc !
video/x-raw-yuv,format=\(fourcc\)I420,width=324,height=240,framerate=5.0 !
videobox right=-1 ! xvimagesink

is ok too.

gst-launch -v videotestsrc !
video/x-raw-yuv,format=\(fourcc\)I420,width=323,height=240,framerate=5.0 !
videobox right=-1 ! xvimagesink

adds a green line.

gst-launch -v videotestsrc !
video/x-raw-yuv,format=\(fourcc\)I420,width=323,height=240,framerate=5.0 !
videobox right=-2 ! xvimagesink

is fine too.  So problem is when both width and correction are odd.

Are you sure it's videobox?

gst-launch -v videotestsrc !
video/x-raw-yuv,width=263,height=192,format=\(fourcc\)I420,framerate=25.0 !
xvimagesink

or

gst-launch -v videotestsrc !
video/x-raw-yuv,width=720,height=576,format=\(fourcc\)YUY2,framerate=\(double\)25.0
! videoscale ! video/x-raw-yuv,width=263,height=192 ! xvimagesink

by itself adds a one pixel green line to the right as well here.

Cheers
