Video and Audio sync problem

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

Hi Ajay Gautam,

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

Above one is working with proper Video and Audio sync.But there was 3 to 4 second delay between live source and  Destination end(where I am displaying video and audio).

I increased latency to 500, I am getting the same delay.





thanks and regards,

Arasu.M

Hi ,
Please update your package to Revision 1.45 ,It will not sync properly if the first audio and video packets do not arrive in the
receiver at the same time.

Re: Video and Audio sync problem

arasu
Hi All,


    Live Source  =================> Capturing Module.
                                                            
   (DM365ipnc)                                     (DM365 leopard)

My Live Source is DM365IPNC.I am capturing Video and audio coming from IPNC in Capturing Module Unit using other Board.

There is no problem in  Sync between Audio and Video in Capturing Module.Now Two or Three second delay between Live Source Module  and  Capturing Module.
                                                            

How to solve this delay problem between these two module.



thanks and regards,

Arasu.M
