How to make rounded cornered video?
 
|
Hello,
I'm finding a way for making rounded video frame using gstreamer. For example, when composing two video frames with compositor element, I hope one inner stream can have rounded edge (like https://helpx.adobe.com/indesign/how-to/round-corners-frame.html is describing) +-----------+ +---------------+ | | +------+ | /-----\ | | V0 | + | V1 | = | | V1 | | | | +------+ | \-----/ V0 | +-----------+ +--------------+ Is there any video filter for that in gstreamer (without opengl) ? I think videomixer, videobox, and compositor has no ability for that.

The element that comes to my mind is shapewipe, though I'm worried, I the example pipeline does not seem to work for me anymore. I'll have a look. https://gstreamer.freedesktop.org/data/doc/gstreamer/head/gst-plugins-good/html/gst-plugins-good-plugins-shapewipe.html > > Seungha Yang > > _______________________________________________ > gstreamer-devel mailing list > [hidden email] > https://lists.freedesktop.org/mailman/listinfo/gstreamer-devel _______________________________________________ gstreamer-devel mailing list [hidden email] https://lists.freedesktop.org/mailman/listinfo/gstreamer-devel |

If I flip the zorder in the example it seems to work: gst-launch-1.0 -v videotestsrc ! video/x-raw,format=AYUV,width=640,height=480 ! shapewipe position=0.5 name=shape ! compositor sink_0::zorder=3 sink_1::zorder=2 name=mixer ! videoconvert ! autovideosink filesrc location=mask.png ! typefind ! decodebin ! videoconvert ! videoscale ! queue ! shape.mask_sink videotestsrc pattern=snow ! video/x-raw,format=AYUV,width=640,height=480 ! queue ! mixer. > > > > > > > Seungha Yang > > > > _______________________________________________ > > gstreamer-devel mailing list > > [hidden email] > > https://lists.freedesktop.org/mailman/listinfo/gstreamer-devel gstreamer-devel mailing list [hidden email] https://lists.freedesktop.org/mailman/listinfo/gstreamer-devel |
