[gst-devel] Video and Audio sync problem

[tamil arasu]

Hi All,


                I am new to gstreamer.I am using pipeline below mentioned
for playing Video and Audio from Live source.

gst-launch rtspsrc location=rtsp://192.168.1.168:8554/mpeg4 latency=10
name=demux demux. ! queue! rtpmp4vdepay ! mpeg4videoparse ! dmaidec_mpeg4 !
TIDmaiVideoSink sync=false videoOutput=LCD videoStd=320X240 demux. ! queue !
rtppcmudepay ! mulawdec ! alsasink

Above Pipeline is working with proper Audio and Video sync.When I was
testing the Video and Audio sync by running the above pipeline so many
times,Sometimes  Audio got delayed about half second.

I am getting this warning  mentioned below


../../../../src/gst-libs/gst/audio/gstbaseaudiosink.c(1449):
gst_base_audio_sink_render (): /GstPipeline:pipeline0/GstAlsaSink:alsasink0:
Unexpected discontinuity in audio timestamps of more than half a second
(0:00:00.569375000), resyncing




thanks and regards,

Arasu.M
