Description
Dummy element that passes incoming data through unmodified. It has some useful diagnostic functions, such as offset and timestamp checking.
Synopsis
Property Details
The "check-perfect" property
"check-perfect" gboolean : Read / Write
Verify that the stream is time- and data-contiguous. This only logs in the debug log. This will be deprecated in favor of the check-imperfect-timestamp/offset properties.
Default value: FALSE
The "datarate" property
"datarate" gint : Read / Write
(Re)timestamps buffers with number of bytes per second (0 = inactive).
Allowed values: >= 0
Default value: 0
The "drop-probability" property
"drop-probability" gfloat : Read / Write
The Probability a buffer is dropped.
Allowed values: [0,1]
Default value: 0
The "dump" property
"dump" gboolean : Read / Write
Dump buffer contents to stdout.
Default value: FALSE
The "error-after" property
"error-after" gint : Read / Write
Error after N buffers.
Default value: -1
The "single-segment" property
"single-segment" gboolean : Read / Write
Timestamp buffers and eat segments so as to appear as one segment.
Default value: FALSE
The "sleep-time" property
"sleep-time" guint : Read / Write
Microseconds to sleep between processing.
Default value: 0
The "sync" property
"sync" gboolean : Read / Write
Synchronize to pipeline clock.
Default value: FALSE
The "check-imperfect-offset" property
"check-imperfect-offset" gboolean : Read / Write
Send element messages if offset and offset_end do not match up.
Default value: FALSE
The "check-imperfect-timestamp" property
"check-imperfect-timestamp" gboolean : Read / Write
Send element messages if timestamps and durations do not match up.
Default value: FALSE
Signal Details
The "handoff" signal
void user_function (GstIdentity *identity,
GstBuffer *buffer,
gpointer user_data) : Run Last
This signal gets emitted before passing the buffer downstream.
