It's not obvious from the existing docs that this option exists, nor that it can be used to give a pipeline an exact length in video frames. https://bugzilla.gnome.org/show_bug.cgi?id=777647

/**

|
|
* @title: videotestsrc
|
|
*
|
|
* The videotestsrc element is used to produce test video data in a wide variety
|
|
* of formats. The video test data produced can be controlled with the "pattern"
|
|
* property.
|
|
*
|
|
* By default the videotestsrc will generate data indefinitely, but if the
|
|
* #GstBaseSrc:num-buffers property is non-zero it will instead generate a
|
|
* fixed number of video frames and then send EOS.
|
|
*
|
|
* ## Example launch line
|
|
* |[
|
|
* gst-launch-1.0 -v videotestsrc pattern=snow ! video/x-raw,width=1280,height=720 ! autovideosink
|
|
* ]|
|
|
* Shows random noise in a video window.
