PCM Streaming

[BogdanS]

Hello

I have a pcm audio file that I want to stream via rtp. When I do

gst-launch-1.0 filesrc location=AudioRaw515151.pcm ! audio/x-raw,
format=S16LE, channels=1, layout=interleaved, rate=8000 ! alawenc !
rtppcmapay ! udpsink host=192.168.2.5 port=5010
I have that kind of message


Pipeline is PREROLLING ...
Pipeline is PREROLLED ...
Setting pipeline to PLAYING ...
New clock: GstSystemClock
Got EOS from element "pipeline0".
Execution ended after 0:00:00.019270487
Setting pipeline to PAUSED ...
Setting pipeline to READY ...
Setting pipeline to NULL ...
Freeing pipeline ...


But I can play this audio, That means that audio is ok.

gst-launch-1.0 filesrc location=AudioRaw515151.pcm ! audio/x-raw,
format=S16LE, channels=1, layout=interleaved, rate=8000 ! alawenc !
rtppcmapay ! rtppcmdepay ! alawdec ! audiosink
I tried to take another file-avi file, take audio from it and maked the same
thing

gst-launch-1.0 filesrc location=file.avi ^
    ! qtdemux name=mux^
    ! queue ^
    ! faad ^
    ! audioconvert ^
    ! audioresample ^
    ! "audio/x-raw, layout=(string)interleaved, rate=(int)8000" ^
    ! alawenc ^
    ! rtppcmapay ^
        ! queue ^
        ! udpsink host=192.168.2.5 port=5010


As you see, this the same thing but with audio from avi. Everything works.

Setting pipeline to PAUSED ...
Pipeline is PREROLLING ...
Pipeline is PREROLLED ...
Setting pipeline to PLAYING ...
New clock: GstSystemClock


When I open Wireshark I see that when I run my pipeline with PCM, it fires
all data without any delay and in every packet that I send is:

Header checksum: 0x0000 [incorrect, should be 0x40b5 (may be caused by "IP
checksum offload"?)]
Message: Bad checksum


So here is a question. I think that I have a problem with timestamps or
something like that, when I do !alawenc (encoding to G711), I am right? And
what solution can fix that problem?
