Properties

  "fd"                       gint                  : Read / Write
  "timeout"                  guint64               : Read / Write

Description

Read data from a unix file descriptor.

To generate data, enter some data on the console folowed by enter. The above mentioned pipeline should dump data packets to the console.

If the "timeout" property is set to a value bigger than 0, fdsrc will generate an element message named "GstFdSrcTimeout" if no data was recieved in the given timeout. The message's structure contains one field:

  • guint64 "timeout": the timeout in microseconds that expired when waiting for data.

Example launch line

1
 
echo "Hello GStreamer" | gst-launch -v fdsrc ! fakesink dump=true
A simple pipeline to read from the standard input and dump the data with a fakesink as hex ascii block.
