Bug 24718

Description of problem:

Join a jitsi conference room. You can join, and you get notification sounds when someone joins or leaves the room, but you cannot hear they say.

Version-Release number of selected component (if applicable):
seems to be faulty since update to 73

How reproducible:
100%

Steps to Reproduce:
1. open https://meet.jit.si/somenameofyourchoice
2. join that same URL using another device (android app, browser on another machine, ...)
3. using the other device, say something in the room → no audio in chrome, same the other way.

You do hear the join/part sounds however, and going to the settings and playing the test audio also works.


A quick look at the changes/specfile revealed that there are new patches that change media support stuff, and looking at one of them I spotted some inconsistencies/errors in those patches (but those might be unrelated) - nothing is printed on terminal or webdeveloper console.

https://svnweb.mageia.org/packages/cauldron/chromium-browser-stable/current/SOURCES/chromium-40-sorenson-spark.patch?revision=1380713&view=markup is the patch where I noticed some mistakes:
171     +    case kCodecMSMPEG4V2:
172	+      return "msmpeg4v2";
173	+    case kCodecMSMPEG4V3:
174	+      return "msmpeg4v2";

note that both return v2, while the latter should be v3
and similarily
196     +  if (codec_id == "msmpeg4v2")
197	+    return kCodecMSMPEG4V2;
198	+  if (codec_id == "msmpeg4v2")
199	+    return kCodecMSMPEG4V3;

codec_id is compared against v2 twice, so the V3 is assigned on error for v2 variant and v3 gets the default result (unsupported)

Those just stood out to me, but I didn't look any further, also not in the other patches, so this might be a total red-herring regarding this bug, but of course should be fixed nevertheless :-)
