How to fill gaps when convert from pcap.

[BogdanS]

Hello.

I make some streaming for example for 10 minutes and catch packets to .pcap. In the middle of the signal it was 3 minutes pause without packets.
Now, when I am doing convert from pcap to .avi, I have length of video is 7 minutes. The same thing I have  with audio streaming.

Now a question, how I can make a video and audio 10 minutes length after convert?

This is a pipeline for video for example

queue, pcapparse, rtph264depay, avdec_h264,  aspectratiocrop, x264enc, avimux, filesink

It would be a bit of a side effect, but you should be able to add the
audiomixer (or compsitor for video) for this purpose. Let us know if
that works for you.

Here I have a .pcap with 30 sec of video.
Also in this .pcap I have audio that works 10yes-10no-10yes.

After I make this

gst-launch-1.0 filesrc location=1.pcap  ! pcapparse name=demux dst-port=5010 ts-offset=1 ^
                ! "application/x-rtp, media=(string)video, clock-rate=(int)90000, encoding-name=(string)H264, payload=(int)96" ^
                ! rtph264depay ^
                ! h264parse ^
                ! queue ! mux.  demux dst-port=4010 ^
                ! application/x-rtp, media=(string)audio, clock-rate=(int)8000, encoding-name=(string)PCMA, channels=(int)1, payload=(int)16 ^
                ! rtppcmadepay ^
            ! queue ! mux. avimux name=mux ! filesink location=test9.avi

I have .avi file in length of 30 sec. But audio works  20 sec as expected, BUT it's a first 20 sec of video! That means it jumps!
