gst-launch-1.0

Build and run a GStreamer pipeline. See also: gst-inspect-1.0. More information: https://gstreamer.freedesktop.org/documentation/tools/gst-launch.html.

• Play test video in a window:

gst-launch-1.0 videotestsrc ! autovideosink

• Play test audio:

gst-launch-1.0 audiotestsrc ! autoaudiosink

• Play a media file in a window:

gst-launch-1.0 playbin uri={{protocol}}://{{host}}/{{path/to/file}}

• Re-encode a media file:

gst-launch-1.0 filesrc location={{path/to/file}} ! {{file_type}}demux ! {{codec_type}}dec ! {{codec_type}}enc ! {{file_type}}mux ! filesink location={{path/to/file}}

• Stream a file to an RTSP server:

gst-launch-1.0 filesrc location={{path/to/file}} ! rtspclientsink location=rtsp://{{host_IP}}/{{path/to/file}}

• Force an End Of Stream event if the pipeline is shut down with <Ctrl c> for containers that require finalization such as mp4:

gst-launch-1.0 {{[-e|--eos-on-shutdown]}} videotestsrc ! x264enc ! mp4mux ! filesink location={{path/to/file.mp4}}

• Multiplex together test video and test audio into a file:

gst-launch-1.0 {{[-e|--eos-on-shutdown]}} videotestsrc ! x264enc ! {{element_name}}. audiotestsrc ! opusenc ! {{element_name}}. matroskamux name={{element_name}} ! filesink location={{path/to/file.mkv}}
