Test streams (GStreamer command-line cheat sheet)
### Display a test pattern
gst-launch-1.0 videotestsrc ! videoconvert ! autovideosink
This should display the test pattern in a window, that looks a bit like this:
There are multiple test patterns available, such as
| Pattern | Example |
|---|---|
videotestsrc pattern=snow |
 |
videotestsrc pattern=red (and blue, green, white and black) |
 |
videotestsrc pattern=pinwheel |
 |
videotestsrc pattern=smpte100 (color test bars) |
 |
videotestsrc pattern=colors |
 |
For the full list of patterns, see https://gstreamer.freedesktop.org/data/doc/gstreamer/head/gst-plugins-base-plugins/html/gst-plugins-base-plugins-videotestsrc.html
Listen to a test audio (beep)
gst-launch-1.0 audiotestsrc ! audioconvert ! autoaudiosink
Combine both the test pattern and test audio:
gst-launch-1.0 audiotestsrc ! autoaudiosink videotestsrc ! autovideosink
