Problem with clockoverlay and theoraenc

[Fabrício Ceolin]

Hi,

I'm testing the following complex pipeline:

gst-launch videotestsrc do-timestamp=true pattern=0 ! videoscale method=1 ! videorate ! video/x-raw-yuv,format=\(fourcc\)UYVY,framerate=2/1,width=640,height=480 ! ffmpegcolorspace ! videoscale method=1 ! video/x-raw-yuv,width=320,height=240 ! videobox border-alpha=0 alpha=1 top=-240 left=-320 ! mix. videotestsrc do-timestamp=true pattern=1 ! videoscale method=1 ! videorate ! video/x-raw-yuv,format=\(fourcc\)UYVY,framerate=2/1,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-timestamp=true pattern=0 ! videoscale method=1 ! videorate ! video/x-raw-yuv,format=\(fourcc\)UYVY,framerate=2/1,width=640,height=480 ! ffmpegcolorspace  ! videoscale method=1 ! video/x-raw-yuv,width=320,height=240 ! videobox border-alpha=0 alpha=1 top=-240 left=0 ! mix. videotestsrc do-timestamp=true pattern=0 ! videoscale method=1 ! videorate ! video/x-raw-yuv,format=\(fourcc\)UYVY,framerate=2/1,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=-320 ! mix. videomixer name=mix  ! ffmpegcolorspace ! clockoverlay ypad=5 halign=right valign=bottom shaded-background=false font-desc=\"DejaVuSans Bold 10\" time-format=\"%Y/%m/%d %H:%M:%S\" ! queue ! theoraenc name=theora1 ! oggmux name=oggmux1 ! filesink name=fsink1 location=/tmp/test1.ogg t1.

It's simulate my environment, that gets 4 640x480 YUV video source, converts to one video 640x480 with 4 320x240 on each quadrant.

See the clockoverlay at near end. When I'm playing the test1ogg, the clock is very slowed compared to real time.

Is it a bug or a error on pipeline setup?

Thanks

You seem to have done  a typo mistake,
please change the framerate from 2 to >=25 fps in the capsfilter :)

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
