Basic tutorial 3: Dynamic pipelines - GStreamer

WebThe pipeline design is made to have little overhead above what the applied filters induce. This makes GStreamer a good framework for designing even high-end audio applications which put high demands on latency. One of the most obvious uses of GStreamer is using it to build a media player. GStreamer already includes components for building a ... WebExample launch line. gst-launch-1.0 videotestsrc ! capsfilter caps=video/x-raw,format=GRAY8 ! videoconvert ! autovideosink.
