Rob, could you attach the Chrome SDP please?

Thanks Adam...that would be awesome 8)
I'm running a bunch of SDP mangling tests this week to see if I can
isolate this further and learn more about the interop challenges so
if I work out anything useful about this specific ERR I'll post it here.

To be clear, all of the "SDP Parsing Error" messages here are merely
warnings, not failures. On a first examination of the code path
that an
get you to "Could not negotiate media lines; cause = ERR", I'm
pretty
sure the situation you ran into below was a DTLS negotiation
failure.
One of the things I plan to do is comb through everywhere we
send back
the rather obtuse "cause = ERR" and change it to be more
illuminating.

Hi Rob,
Firefox and Chrome are not directly compatible. apprtc
adapts them a bit
to get them to work together. You can copy what they do
from files like
this:
https://apprtc.appspot.com/js/__adapter.js
<https://apprtc.appspot.com/js/adapter.js>
https://apprtc.appspot.com/js/__main.js
<https://apprtc.appspot.com/js/main.js>
The bug for Bundle is here -
https://bugzilla.mozilla.org/__show_bug.cgi?id=784491
<https://bugzilla.mozilla.org/show_bug.cgi?id=784491>
Though, how some of this should work exactly is still being
discussed in
the IETF standards groups MMUSIC and RTCWeb which meet next
week in Berlin.

Hi,
I couldn't see that anyone had raised this anywhere and
it seems unrelated
to this topic on discuss-webrtc
https://groups.google.com/__forum/#!topic/discuss-webrtc/__dLsbz6Xwxc0
<https://groups.google.com/forum/#!topic/discuss-webrtc/dLsbz6Xwxc0>
- so I
thought I'd share the error message I'm receiving.
If you'd like me to raise this as a bug please let me
know...but thought
it might be better first as just an informational post.
So setting up a video call between the latest Chrome
(28.0.1500.71
(Official Build 209842) ) and Firefox 22 & Nightly
(25.0a1 (2013-07-25)) on
Linux I get this SDP parsing error message in Firefox.
"Could not negotiate media lines; cause = ERR | SDP

Warning: Group attribute type unsupported (BUNDLE). |
SDP Parsing Error:
Warning: Unrecognized attribute (msid-semantic) | SDP

However, in the exact same app I can setup a video call
between two
Firefox tabs or separate browsers so it's definitely
working OK with
Firefox SDP.
If you'd like a full copy of the Chrome SDP and related
signaling please
let me know...but I'm sure you've got a good collection
of this already 8)
