Problem with clockoverlay and theoraenc

[Fabrício Ceolin]

Hi Kapil,

I really want 2 fps. I solve the problem adding a is-live at videosource.
It's make sense, isn't?

gst-launch videotestsrc do-timestamp=true is-live=true pattern=0 !
videoscale method=1 ! videorate !
video/x-raw-yuv,format=\(fourcc\)AYUV,framerate=2/1,width=6
deo/x-raw-yuv,width=320,height=240 ! videobox border-alpha=0 alpha=1
top=-240 left=-320 ! mix. videotestsrc do-timestamp=true is-live=true
pattern=1 ! videoscale method=1 ! video
width=640,height=480 ! ffmpegcolorspace ! videoscale method=1 !
video/x-raw-yuv,width=320,height=240 ! videobox border-alpha=0 alpha=1 top=0
left=0 ! mix. videotestsrc do-timesta
orate !
video/x-raw-yuv,format=\(fourcc\)AYUV,framerate=2/1,width=640,height=480 !
ffmpegcolorspace  ! videoscale method=1 !
video/x-raw-yuv,width=320,height=240 ! videobox borde
mestamp=true is-live=true pattern=0 ! videoscale method=1 ! videorate !
video/x-raw-yuv,format=\(fourcc\)AYUV,framerate=2/1,width=640,height=480 !
ffmpegcolorspace ! videoscale m
order-alpha=0 alpha=1 top=0 left=-320 ! mix. videomixer name=mix  !
ffmpegcolorspace ! clockoverlay ypad=5 halign=right valign=bottom
shaded-background=false font-desc=\"DejaVuSa
eoraenc name=theora1 ! oggmux name=oggmux1 ! filesink name=fsink1
location=/tmp/test1.ogg t1.

Thanks!
