PCR timestamp

[enki]

I’m testing an IP camera connected to my network and I want to know if there is any way to know the exact time a frame is received. The aim of the test is to measure the time spent between each frame is received to set up a buffer for an application we want to develop.

I tried to find software that provides this data but I found nothing so I tried to calculate it myself with the timestamps saved by VLC.

I’m dumping data from the camera to a .ts file and see the PCR saved and that way I can see the moment the frame arrived. Is this an acceptable solution? I'd like to know how vlc makes this dumping so I can see if the calculations are correct.
Is there any better way to calculate this interval?

Thanks in advance
