Ok, as tends to be the case with me I've figured out what my problem was
only minutes after sending this request off: The root cause of my poor
one-way audio latency is the android phone I was using to run my WebRTC app.
For reference, the problem phone is an LG Optimus Zone 2 (Verizon, phone
code VS415PP) running Android KitKat 4.4.2. I make the note in case someone
else runs across a similar problem.

 

Also for reference, I have another low-end android device that works great
with Crosswalk in this manner: ZTE Zinger (T-Mobile, Model #: Z667T). Both
transmit and receive audio WebRTC latencies are below the quarter-second
mark, which is much more palatable for my intended use.

Subject: [Crosswalk-help] Crosswalk WebRTC Latency on Android ARM devices

 

Hi everyone,

 

I recently built a WebRTC phone using the Plivo WebSDK and am running into a
puzzling issue: there is a one-second delay when the person I call via
WebRTC speaks to me. It does not matter what the endpoint is (Another WebRTC
client, a SIP phone or a hard-line, it's always about a seconds worth of
delay. What doesn't make sense to me is that when I talk on my WebRTC phone
app, the other end receives the audio within a quarter second.

 

This leads me to my question: Is there a way to tune WebRTC latencies in
Crosswalk? Being new to WebRTC I'm not sure how much lag an 'incoming' audio
stream is subject to before being played back. I am using Android ARM
Webview version 10.39.235.15. Any guidance, advice or suggestions are
appreciated. I'm chasing down all my leads at this point.

 

Rion
