Dear All,
Is there any way, by which some audible time stamp information could be
added to audiotestsrc plugin? What I mean is similar to videotestsrc !
timeoverlay in the case of video.
Basically, I would like to do delay measurement for video and audio over
RTP. I could do for the video by the following.
/ autovideosink
videotestsrc - timeoverlay - tee
\ x264enc - rtph264pay - udpsink
udpsrc - rtph264depay - decodebin - autovideosink
Now, If I could compare both autovideosink simultaneously, I could get an
estimate of video encoder/decoder rtp packetzer/depacketizer delay.
I would like to do similar for AAC audio. If I could an "equivalent" of
timeoverlay for audio, then I could use the same concept.
Any idea would be really appreciated.
Thanks and Regards
Anand
