Hi all,
I'm planning to write a testing tool which can output RTP packet with
AAC-LC frame inside and out from UDP.
The server side, I expect the command like
*"gst-launch-1.0 udpsrc port=1234 !
application/x-rtp,media=audio,clock-rate=16000,encoding-name=MPEG4-GENERIC,mode=AAC-lbr
! rtpmp4gdepay ! aacparse ! avdec_aac ! autoaudiosink"*
The client side, my program is
*app->pipeline = gst_parse_launch("appsrc name=ringbuf ! aacparse !
rtpmp4gpay pt=97 ! udpsink host=192.168.143.101 port=1234", NULL);*
Question:
1. The server always return failure when receive packet? Why? How can I fix
it?

2. At client part, program will always be Segmentation fault after calling
stop feeding. How can I debug it?

Please help. If you want, I can upload my code. Thanks.
