It requires some code digging which is going a bit slow. Unfortunately, it does require digging into the code. There are many standard RTP metrics (for example, burst/gap, etc.), they are listed at http://www.iana.org/assignments/rtcp-xr-block-types/rtcp-xr-block-types.xhtml#rtcp-xr-block-types-1 > Is there any documentation around what each statistic really mean ? > > Thanks > Dee > > > > On Wed, Aug 20, 2014 at 1:26 AM, Varun Singh <vsingh.ietf@gmail.com> wrote: >> >> Hi, >> >> Since you are discussing about chrome, there are some additional stats >> appended with a `goog` identifier in getStats() which may help (e.g., >> frame playout time in ms compare that to the frame rate). >> >> There are additional stats discussed in the wiki >> (https://www.w3.org/2011/04/webrtc/wiki/Stats) but AFAIK they are not >> yet implemented by any browser.
