[Linphone-developers] rtp timestamp for video

I am using oRTP to stream the video data from the camera on Linux. I am using H.263 codec  for sending the video data. I am using custom H.263 codec and added the H.263 header packetization  routines using  rtp_session_create_packet() function and then sending the data using
rtp_session_sendm_with_ts() function.
Here I am incrementing "user_ts" value by 3000 Since the Camera outputs 30 frames per second.
i.e. 90000/30 = 3000.
But when i profiled the rtp_session_sendm_with_ts() function using gettimeofday it is taking 400 millisecond which is very large value.

Is there any thing wrong in my timestamp calculation. Please let me know.

Warm Regards,
