One could make all the position properties controllable. Then you could animate them from the application.

Hi,
I'm just trying to do some scrolling text effect on a video frame ,could you give me some advice?just like which plugin I can use(I used to try the textoverlay,but it didn't seem like to have this property). English is not my mother tongue,so I might have some mistakes in explaining my problems,hope your advice! Thanks! |
TextOverlay
(http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gst-plugins-base-plugins/html/gst-plugins-base-plugins-textoverlay.html) should work. Like adding: ! textoverlay text="SampleText" ! So does ClockOverlay/TimeOverlay. Here are two full command examples, as reference: $ gst-launch-0.10 v4l2src device=/dev/video0 ! ffmpegcolorspace ! \ video/x-raw-yuv,width=640,height=480 ! clockoverlay \ halign=left valign=toptext=2012-02-28: \ shaded-background=true! autovideosink $ gst-launch-0.10 v4l2src device=/dev/video2 ! ffmpegcolorspace !\ video/x-raw-yuv,width=640,height=480 ! clockoverlay \ halign=left valign=toptext=2011-12-08: \ shaded-background=true! theoraenc quality=32 ! \ oggmux ! filesinklocation=./video-ch3.ogg That had been tested with real capture card, Sensoray Model 811/911 (http://www.sensoray.com/products/811.htm or http://www.sensoray.com/products/911.htm).

Sorry, just noticed, there was a space missing between valign=top and
text=2012-02-28:, in the sample commands. > TextOverlay > (http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gst-plugins-base-plugins/html/gst-plugins-base-plugins-textoverlay.html) > should work.
