pcr_pts adjustment
Posted: Fri Dec 06, 2019 5:15 pm
I've been experimenting with a new H264 / 265 encoder but found when I ran a script on the Jetson I was getting PCR DTS timing errors. At G0MJW's suggestion I change the value of the PCR_PTS variable from 200000 to 350000 this virtually eliminated the PCR DTS timing errors and resulted in a much more fluid video stream.
So I thought I'd repeat this tweak on the Portsdown but so far have not been able to find the correct line of code to edit - can anyone tell me where PCR_DTS is located ?
Edit - I suspect it's hard coded to 200000 as per below - correct ?
-c:v copy -max_delay 200000 -muxrate $BITRATE_TS \
I've changed it to 400000 and will see how it runs.
