<DIV><FONT size=2 face=Arial> Hello to all Nightly Testers (and hopefully
Mozilla devs) reading this!<BR><BR>OS Specifics: <BR><BR>Windows_NT 6.0,
i.e.<BR>Windows Vista SP2 32bit, en-US localization.<BR>All Microsoft Updates
(up to July 2016) applied <BR>(contrary to popular belief, Vista is still under
<BR>extended Microsoft support and will continue <BR>to be so until April
2017!).<BR><BR>Nightly specifics:<BR><BR>Version: 51.0a1 (x86)<BR>BuildID:
20160901030202<BR>Built from
https://hg.mozilla.org/mozilla-central/rev/b7f7ae1<BR><BR>BBC iPlayer
Requirements<BR><BR>1. You must have a valid UK IP address <BR>(or "acquire" one
that has not been <BR>blacklisted by BBC's geo-location filter ;-) ).<BR>2. As
of today, to access video-on-demand, <BR>you have to be covered by a valid UK TV
<BR>licence; for testing purposes in the context <BR>of this report, click the
<BR>"I have a TV Licence." phrase in the pop-up... <BR><BR>iPlayer HTML5
Requirements<BR><BR>1. If you do not have the Flash NPAPI plugin <BR>installed,
then iPlayer will default to HTML5 <BR>in Nightly 51.0a1<BR>2. If you do have
the Flash NPAPI plugin installed, <BR>then do one of two things: <BR><BR>a:
about:addons => Plugins => <BR>Shockwave Flash => Never Activate
<BR>and restart Nightly<BR><BR>b. Visit: <BR></FONT></DIV>
<DIV><FONT size=2 face=Arial><A
href="http://www.bbc.co.uk/html5">http://www.bbc.co.uk/html5</A><BR></FONT></DIV>
<DIV><FONT size=2 face=Arial>and on the top right click the <BR>"Opt in to the
HTML5 Player" <BR>blue ribbon - a cookie is set and <BR>the wording changes to
<BR>"Opt out of the HTML5 Player" <BR>Take care NOT to delete that <BR>cookie
during your test.<BR><BR>Visit a VOD iPlayer page, e.g.
<BR><BR>http://www.bbc.co.uk/iplayer/episode/b07pqw06/reading-and-leeds-festival-2016-foals<BR><BR>Click
the "Play" icon on the player; <BR>agree to the age check and not set
<BR>Parental Guidance Lock by clicking Play: <BR><BR>Expected results:
<BR><BR>The video should start playing...<BR><BR>Actual results: <BR><BR>1. If
NPAPI Flash is not installed or it's disabled, <BR>then you get a <BR><BR>"This
content cannot be played in <BR>our HTML5 Player<BR>Download Flash Player
now"<BR><BR>screen message. <BR><BR>2. If NPAPI Flash is installed and enabled
<BR>but you have opted in to HTML5 via a set cookie, <BR>you get another failure
message with different wording: <BR><BR>"This content doesn't seem to <BR>be
working. <BR>Please try again later."<BR><BR>In both cases 1 & 2, web
console reports: <BR><BR>"Media resource
blob:http://emp.bbc.co.uk/b00a382c-9759-4a66-913e-cec8c46e6360 could not be
decoded." <BR><BR>I consider this to be an important bug, <BR>because BBC will
eventually switch to their <BR>HTML5 player exclusively, so expect all UK
<BR>users to be really upset... <BR><BR>I got access to sister's Windows 7 SP1
64bit <BR>laptop and the bug is reproducible there, too! <BR>Starting a new
clean profile in latest Nightly 51.0a1 <BR>makes no difference; the same goes
for enabling/<BR>disabling e10s...<BR><BR>As of now, DeveloperEdition 50.0a2,
Beta 49.0b8 <BR>and Release 48.0.2 remain unaffected.<BR><BR>To aid the devs, I
spent this afternoon (in my timezone) <BR>to do a dissection and found out that:
<BR><BR>Last good build:
Nightly-51.0a1.en-US.win32[20160823030224]<BR>cset=24763f5<BR>First bad build:
Nightly-51.0a1.en-US.win32[20160823072522]<BR>cset=052656f<BR><BR>Regression
range:
<BR><BR>https://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=24763f5&tochange=052656f<BR><BR>So
it was the re-spin on Aug 23rd that broke things! <BR>There are exactly 190
csets in that range, I'll leave it to <BR>the experts to pinpoint probable
culprits...<BR><BR>I lack adequate Bugzilla skills/account, so I kindly ask
<BR>one of my readers to file an appropriate bug... :-)<BR><BR>Kind
regards</FONT></DIV></BODY></HTML>
