922051 - Image freezes on caller side after a short period of time

Status: RESOLVED INCOMPLETE

(Core :: WebRTC: Audio/Video, defect)

Description

[Mihaela Velimiroviciu (:mihaelav)]

Mozilla/5.0 (Windows NT 5.2; WOW64; rv:26.0) Gecko/20100101 Firefox/26.0

The image freezes on caller side in a 1:1 call with another user on Win XP machine.

Environment:
Callee (1st person in the conversation): Firefox 22.0/Win XP
Caller (2nd person in the conversation): Firefox 26.0a2/Win XP

Steps:
1. Create a conversation on https://apprtc.webrtc.org/ from a Win XP machine using Firefox 22
2. Join the conversation created on step 1 from another Win XP machine using Firefox 26.0a2 (current latest Aurora build)
3. Wait for a while (~15-20 seconds)

Expected result: Image and sound work fine on both ends of the conversation

Actual result: On the caller side, the callee's image freezes.

Note: The issue is not reproducible on Firefox 25 beta 3, nor Firefox 22 (on caller's machine)

Just the callee's view freezes, own view works fine.

First bad Nightly: 20 Sept 2013
The Sept 19 builds (26.0a2, 27.0a1) don't connect.

Issue is also reproducible for the following environments, as well:
Caller: Firefox 27.0a1 on Windows 7	 
Callee: Firefox 22.0 on Mac OSX 10.8

Caller: Firefox 27.0a1 on Mac OSX 10.8	 
Callee: Firefox 22.0 on Windows 7 - here, caller's image freezes

FF 22 is not an interesting target anymore.  Do we see this with 27 talking to 25 or 26 (or 27b7)?  If so, can we get logs with NSPR_LOG_MODULES=signaling:5,mtransport:5,webrtc_trace:65535 NSPR_LOG_FILE=xxx WEBRTC_TRACE_FILE=yyyy R_LOG_LEVEL=3 R_LOG_DESTINATION=stderr R_LOG_VERBOSE=1

Note that we've recently diagnosed a problem with TURN TCP that causes the remote video image to freeze; I don't *think* TURN TCP is in 27 (ekr?)  This was fixed yesterday in bug 960296.  There is a separate question as to why it's using TURN TCP when it shouldn't be.

I'll look at the regression range indicated by the older reports.

TURN TCP will be in FF 28 but no earlier

Mihaela: Does this still happen?  If so, re-open.  Thanks!
