1177767 - Use a Gecko-specific string for MuxingApp and WritingApp in WebM files

Status: NEW

(Core :: Audio/Video: Recording, defect, P3)

Description

[Matthew Gregan [:kinetik]]

We're currently using the string "QTmuxingAppLibWebM-0.0.1" for the MuxingApp and WritingApp subelements of a WebM SegmentInformation.  That string is produced here:

http://mxr.mozilla.org/mozilla-central/source/media/libmkv/WebMElement.c#120

I understand this is inherited from the libmkv library we're using to write WebM files, but we should use something Gecko-specific to make tracking the origin of and debugging problems related to Gecko-produced files easier.

Without having thought about it a great deal, something like "$ProductName $Version/$BuildID ($OriginalMuxerString)" makes sense to me, e.g. "Firefox 41.0a1/20150625030202 (QTmuxingAppLibWebM-0.0.1)".
