我想通过 v4l2src 从相机捕获图像,然后捕获的图像显示在 2 个接收器中,一个是原始图像,一个是处理后的图像。有谁知道如何做到这一点?我正在使用 gstreamer 1.0。
你应该看看tee元素:https ://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer-plugins/html/gstreamer-plugins-tee.html
tee
这是一个满足您需求的 gst-launch 示例:
gst-launch-1.0 -v v4l2src ! tee name=t \ t. ! queue ! videoscale ! video/x-raw,width=640,height=480 ! \ videoconvert ! autovideosink \ t. ! queue ! videoscale ! video/x-raw,width=360,height=240 ! \ videoconvert ! autovideosink
