Hi,
May be you can get the pad caps to see it's audio or video pad.
static void on_pad_added (GstElement *element, GstPad *pad, gpointer data)
{
GstCaps *caps = NULL;
GstStructure *structure = NULL;
caps = gst_pad_get_caps (pad);
structure = gst_caps_get_structure (caps, 0);
media_type = g_strdup (gst_structure_get_string (structure, "media"));
structure = NULL;
gst_caps_unref (caps);
caps = NULL;
if (0 == g_strcmp0 ("audio", media_type))
{
// audio stuff
}
else if (0 == g_strcmp0 ("video", media_type))
{
// video stuff
}
else
{
// not supported media type
}
g_free (media_type);
}

I am writing client code which receives audio+video.
When I am trying to connect rtpbin and depayloader how to know which session is this?
Actually,I am writing the code in C and am trying to use g_signal_connect.
So that I can use
g_signal_connect (rtpbin, "pad-added", G_CALLBACK (pad_added_cb), videodepay);
g_signal_connect (rtpbin, "pad-added", G_CALLBACK (pad_added_cb), audiodepay); using if -else condition but for that I need to find out the session how I can do?
my client pipeline is:
VIDEO_DEC="rtph264depay ! ffdec_h264"
AUDIO_DEC="rtpmp4gdepay ! faad"
VIDEO_SINK="ffmpegcolorspace ! autovideosink"
AUDIO_SINK="autoaudiosink"
DEST=127.0.0.1
LATENCY=100
gst-launch -v gstrtpbin name=rtpbin \
udpsrc caps=$VIDEO_CAPS port=5000 ! rtpbin.recv_rtp_sink_0 \
rtpbin. ! $VIDEO_DEC ! $VIDEO_SINK \
udpsrc port=5001 ! rtpbin.recv_rtcp_sink_0 \
rtpbin.send_rtcp_src_0 ! udpsink port=5005 host=$DEST sync=false async=false
udpsrc caps=$AUDIO_CAPS port=5002 ! rtpbin.recv_rtp_sink_1 \
rtpbin. ! $AUDIO_DEC ! $AUDIO_SINK \
udpsrc port=5003 ! rtpbin.recv_rtcp_sink_1 \
rtpbin.send_rtcp_src_1 ! udpsink port=5007 host=$DEST sync=false async=false
Same thing in C language ,please reply.
Please reply.
If you know other way please do let me know.
Thaks in advance.
