source pcap dump + filtered pcap dump + ogg result

Hi, I using Centos 7 Linux machine with Gstreamer 1.4.5 for encoding ogg files
from captured network traffic.
As input I have network dump in *pcap format with 3 rtp streams inside: 1 video
stream (VP8) and 2 audio streams (G711).

With tshark tool (from Wireshark tool-packet) I filtered out only audio data
also to *pcap file. And then use gstreamer to encode to stereo ogg format.

gst command:

gst-launch-1.0 interleave name=i filesrc location=/tmp/audio1.pcap ! pcapparse
dst-ip=10.10.4.10 !
application\/x-rtp,payload=0,clock-rate=8000,encoding-name=PCMU ! rtppcmudepay
! mulawdec ! audioconvert ! audioresample ! audio\/x-raw,rate=8000,format=F32LE
! queue ! i.sink_0 filesrc location=/tmp/audio1.pcap ! pcapparse
src-ip=10.10.4.10 !
application\/x-rtp,payload=0,clock-rate=8000,encoding-name=PCMU ! rtppcmudepay
! mulawdec ! audioconvert ! audioresample !
audio\/x-raw,channels=\(int\)1,rate=8000,format=F32LE ! queue ! i.sink_1 i.src
! capssetter caps=audio\/x-raw,channels=2,channel-mask=\(bitmask\)0x3 !
audioresample ! audioconvert ! vorbisenc quality=0.5 ! mux. oggmux name=mux !
filesink location=/tmp/out.ogg

As resualt I have ogg file with incorrect duration:

oggz-info /tmp/out.ogg
Content-Duration: 5124095:34:33.629         <---- ????

Vorbis: serialno 1067813195
        414 packets in 232 pages, 1.8 packets/page, 9.188% Ogg overhead
        Audio-Samplerate: 8000 Hz
        Audio-Channels: 2

or

ogginfo /tmp/out.ogg
Processing file "/tmp/out.ogg"...

        Average bitrate: 0.000000 kb/s

In attachment added source pcap dump , filtered pcap dump with only audio
inside and resulting ogg file.
