SRT Stats

[RobbieElias]

Hello,

Is it possible to add support for SRT stats? The SRT library includes functions for obtaining stream stats as described here:

https://github.com/Haivision/srt/blob/master/docs/API/statistics.md

Specifically, the library exposes the following functions for obtaining stats:

int srt_bstats(SRTSOCKET u, SRT_TRACEBSTATS * perf, int clear)
int srt_bistats(SRTSOCKET u, SRT_TRACEBSTATS * perf, int clear, int instantaneous)

Thanks!

Hello,

Which stats do you need exactly?
You already have stats about frames sent and drop video and audio

[RobbieElias]

The ones I specifically need are:

mbpsBandwidth
msRTT
pktSndDropTotal
pktSndLossTotal
pktSentTotal
byteSentTotal

Are the stats you currently include based on the SRT socket? Those are more accurate in determining what is actually received/dropped by the server.

[pedroSG94]

You have:

mbpsBandwidth
pktSndDropTotal
pktSentTotal

This is not implemented yet:

msRTT
pktSndLossTotal
byteSentTotal

Anyway, this should be easy to implement. The only problem could be pktSndLossTotal because the server is who decides if a packet is lost.

[RobbieElias]

I ran some tests, and the getDroppedVideoFrames() and getDroppedAudioFrames() don't represent the actual number of frames lost in transmission. Using the actual SRT stats would be more accurate for determining true packet loss.

Hello,

Yes, that is not developed yet.
I will add it

I did a PR for this:
#1889
Try this gradle:
