timestamping in mpegtsparse.

[Jyoti-2]

Hi all,

I am writing an application to stream MPEG-2 TS RTP Payloaded packets over UDP.
My server was sending the packets at too high rate.

I looked upon a mail by Wim saying the timestamping on mpegtsparse is the solution
for the controlling the rate.

Is the timestamping implemented in latest version of mpegtsparse?

Regards
Jyoti

Hello,

Your pipeline seems correct, but since the input stream comes from a
file, your pipeline is playing as fast as possible. You should try to
add sync=true on your  udpsink.

gst-launch filesrc location=stream.ts ! mpegtsparse ! rtpmp2tpay !
udpsink port=1234 sync=true

Hi,

Thanks for the reply. I did add sync=true on udpsink but there is no change.
Is there any other method where I can stream properly.

Thanks,
jyoti

this should work:

gst-launch \
  filesrc location=ksc_062707_sts117_launch_1080i-29-97.ps.mpg \
  ! tee name=splitter  \
  ! queue \
  ! udpsink host=226.226.226.100 port=2266 \
  splitter. \
  ! queue \
  ! mpegpsdemux \
  ! fakesink sync=True

Hi Marc,

While writing an application equivalent to the below pipeline. The pipeline hangs after setting itself to GST_STATE_CHANGE_ASYNC. I do wait state change using gst_element_get_state.

gst-launch filesrc location=collateral.ts ! tee name=splitter  \

splitter.  ! queue  ! mpegtsparse ! rtpmp2tpay ! udpsink host=226.226.226.100 port=2266 \
 splitter.  ! queue  ! mpegpsdemux  ! fakesink sync=TRUE

Whenever I am adding the branch containing demux, fakesink the pipeline never changes its state to PLAYING.
I add the fakesink element in the "pad-added" signal callback function.

I individually request src pads & then connect separately to mpegtsparse sinkpad and also to mpegtsdemux sinkpad.

Can someone hint if the method am following is proper? or is there any obvious mistake..

Thanks,
Jyoti
