Is it possible to determine the outbound packet loss (in voice channels)? #2225

I asked about that in the discord.py Discord yesterday, and got an "I think not" answer, so I figured I'd ask here, just to be sure.

I'd like to find out the outbound packet loss for my bot when it is connected to a voice channel. I haven't found anything in the docs for that, though, so I was wondering if there was something implemented for that and, if not, if there was a way to do it without reinventing the wheel.

Thanks for your awesome work!

Good news, you actually can. Bad news, its part of voice receive. The one type of RTC control packet discord sends (as far as I can tell) is the ReceiverReport type, which has some statistics for the data you send. They look like this:

<ReceiverReportPacket report_count: 1, ssrc: 13, reports: (RReport(ssrc=13, perc_loss=0, total_lost=0, last_seq=453, jitter=3, lsr=0, dlsr=2432705982),), extension: None>

Checking this has also made me notice that currently (in my voice recv fork) that to receive packets about your send statistics you need to have a listener attached, even if it does nothing. This is obvious from a logical perspective but backwards from a library usage perspective. I suppose i'll have to design this in as some sort of special sink or something.
