<br><br></span>The easiest would be to just take a look at the debug logs. The second

<br>gst_bin_iterate_recurse() could be useful here.
<br><br>Basically, if there is no audio in your pipeline anymore, the only

<br>and b) the rtpjitterbuffer latency.
<br><br>a) is most likely using vtdec here, Apple VideoToolbox based decoder.
<br>Unfortunately that API does not provide proper latency information so
<br>we're doing guesses here, and those guesses are better if you use
<br>baseline profile.
<br>You could alternatively try the libav software decoder, avdec_h264.
<br><br>b) is what you configure on rtspsrc.
