Bitrate of a stream

[SR.OR4CL3]

Hi, a need get a bitrate of a stream, i'm use the below code

import gst

host="127.0.0.1"
port=1234
p = "videotestsrc ! rtpvrawpay ! udpsink host=%s port=%s" %(host, port)

pipeline = gst.parse_launch(p)
udpsink = pipeline.get_by_name("udpsink0")

def print_stats():
    data = udpsink.emit("get_stats", host, port)
    stats = "bytes_sent: %s, packets_sent: %s, connect_time: %s"
%(data[0], data[1], data[2])
    print stats
    return True

import gobject
gobject.timeout_add_seconds(1, print_stats)

pipeline.set_state(gst.STATE_PLAYING)

import gtk
gtk.main()

But, he don't give me a bitrate, someone could help me ? ?????

It's named "get-stats", I'm surprise it didn't abort.

I don't think you can read a GstStructure like this.

I see that you are using gstreamer 0.10 which is really ancient. consider
switching to 1.x as soon as possible.

In 0.10 it indeed was called "get_stats" and you used this snippet as a
basis:

To get the bitrate, you should do the calculation yourself based on total
bytes sent and the time that has passed. AFAIK it is not included in the
"stats" emitted by udpsink
