I mentioned this on another thread but any bugs you find with
playing videos that can be resolved by disabling
media.mediasource.enabled is a Media Source Extensions bug. You
should file a bug in Core :: Video/Audio and mark it as blocking bug

<div>I've encountered this same
issue in last days, don't
really remember when was first
time I saw it. Also it's not
only sound, sometimes
video/image stops while sound
is still playing. And
sometimes can't pause or
resume that stuck video. It
seems to be somewhat random,
for example it didn't happen
on first video, but on 2nd one
at exactly 4:12 sound stopped
and even clicking pause it
didn't actually paused while
it was marked as paused and
couldn't resume.<br>

Probably should submit issue to

I mentioned my
system at the
end: "I've
only tested
this on
Windows 7
x64", if
that's what
you meant. As
for my mail
client, I'm
not sure why
that's
relevant, but
I'm currently
just using the
web interface
of Gmail in
Nightly. If
you mean
system specs,
I'm running it
off the
onboard
Realtek ALC
888b chipset
of my
GA-Z68XP-UD3.
I'm not sure
how you're

thought VLC
was only for

I've
been having
issues with
with the HTML5
player on
YouTube<br>
on the
past few days'
worth of
Nightlies. I'm
currently on
the<br>
latest
Nightly as of
10/29/2014,
however, I've
been having<br>
issues
with YouTube
where videos
will play fine
for a few<br>
minutes before
the audio cuts
out at
completely
sporadic<br>
moments on
completely
random videos.
Where the
audio cuts out<br>
is
usually
consistent
though as long
as the video
starts at<br>
the
same place
every time.
Strangely, the
HTML5 player
breaks<br>
around
the same time,
with the video
continuing to
play<br>
without audio,
and for some
reason, if I
pause and
unpause the<br>
video.
I can't pause
the video
afterwards.
The play
button is<br>
permanently
stuck thinking
the video is
paused,
meaning it<br>
shows
the play
triangle
instead of the
pause bars it
should<br>
while
playing, and
the seeker at
the bottom
keeps going.<br>
Clicking on
the player
shows the
animation for
pausing, but<br>
the
neither the
video nor the
seeker pause.
Sometimes
clicking<br>
on an
earlier part
of the video
will restore
audio, other<br>
times,
it will go to
the proper
segment of
video, but
still no<br>
audio,
and sometimes
it will
restore audio,
but will<br>
constantly
play back to
the spot the
audio stopped
as if you<br>
never
rewinded in
the first
place. Other
videos, in
particular<br>
longer
videos (the
one I had an
issue with was
30 minutes<br>
long),
downright
don't stream
properly with
the video
always<br>
buffering,
perhaps
playing for a
couple of
seconds before<br>
buffering
again forever,
but only if
I'm signed
into YouTube<br>
and
the video
attempts to
resume from
where it last
left off.<br>
If I
sign out and
the video just
plays from the
beginning, it<br>
works
fine. It's not
a network
issue as not
only do I not<br>
encounter the
buffering
issue on
stable Firefox
and other<br>
browsers, but
the HTML5
player shows
that the video
is fully<br>
buffered on
the seeker.<br>
<br>
Sorry
for the
extremely long
message, but I
wanted to be
as<br>
specific as
possible on
what issues
I've
encountered.
I've<br>
tried
clearing the
cache,
deleting
YouTube's
cookies, using
a<br>
different
profile,
creating a
clean profile,
resetting<br>
Nightly,
enabling/disabling
e10s, and Safe
Mode. All
plugins<br>
and
addons are
fully updated
or disabled.
I've only
tested<br>
this
on Windows 7
x64.<br>

Which
system? You're
Header to post
doesn't show
the Mail
Client<br>
you are
using.<br>
<br>
The above
play fine, no
hassles - but
I am using a
Linux distro<br>
(openSUSE). I
am also using
VLC as my
video/sound
player and
using<br>
a Creative
sound card.<br>
<br>
However,
there is one
thing which I
*hate* - most
vehemently :-)<br>
(Tm) - and
it's not a
joke: one
needs to exit
YouTube after<br>
viewing a
file in order
to view
another file,
which is damn<br>
annoying.
If one views a
file and then
tries to
follow it up
with<br>
another,
the second
file comes up
with "An error
has<br>
occurred......"
and the second
file will not
play. Exiting<br>
YouTube,
coming back
and selecting
the second
file will then
make<br>
the second
file play
without a
problem.<br>

Ooops, sorry,
I didn't read
the very last
sentence in
the last
paragraph :-(
. Mention of
the client is
because one
can get the
idea of the
system a
person is
using and
follows on
from my
previous
sentence (in
my first
response).<br>
<br>
I mentioned
the video card
I am using
because
whether it is
an onboard
card or an
external one
each requires
a driver and
many problems
may be caused
by not having
up-to-date
drivers for
the video card
or chip.<br>
<br>
Re VLC:
shouldn't have
mentioned it
in this
context. I use
it to view all
videos
downloaded
from YouTube
but Firefox,
of course,
uses the
OpenH264 Video
Codec to
display
YouTube
videos.
