<div dir="ltr">We did not go ahead with the live video stream for
the following reasons:<br>
<ul>
<li>no-one local was willing and able to set-up, baby-sit and
pack-down the video equipment</li>
<li>no-one local was willing and able to do any editing or
other post-production<br>
</li>
<li>the few remote viewers would not have watched a live
stream, due to time-zone differences</li>
</ul>
<p>On the day of the event, there was a howling north-easter,
with unoccupied garden seats blowing around. Unattended video
equipment would have suffered. We did have audio reinforcement
which worked well, although there was quite a bit of
wind-noise despite wind-shield on the mics. It was not workth
recording the audio.<br>
</p>
<p>I did play around with YouTube live streaming. There was no
obvious minimum viewer requirement. It worked fine with OBS
(Open Broadcasting Software) running on an Ubuntu 14.04 box. A
mobile phone had adequate bandwidth to stream the video to the
server, but not enough for a live monitor at the same time. I
thought it strange, because one is mostly uplink, the other
downlink. Watching the stream on a different computer with an
independent connection to the internet worked fine, as
expected.</p>
<p>I would certainly consider YouTube live streaming for a
future event. It was easy for a suitably experienced person to
set up, but not for Grandma.<br>

<li>create a stream event on youtube<br>

<li>download and install OBS (Open Broadcaster Software)

</ul>
<p>Have to do some Real Work now, but it looks promising,
provided that I can satisfy myself that:</p>
<ul>
<li>the event can be relatively private (invitation
only, or at not advertised and unlisted)</li>
<li>the event can be completely free of adverts; I
suspect this will be a pay-for privilege</li>
</ul>
<p>Other factors<br>
</p>
<ul>
<li>3 hours at 1.5 MBits/sec is 2 Gbytes. Allowing for
25% streaming overhead gives 2.5 GBytes. Have to get a
data addon: 2 degrees charges 50c per MB for casual
data usage (for a total of $1200!), but offer a 3 GB
data addon for $50, or about 1.7c / MB<br>
</li>
<li>you standard USB data modem advertises 21 Mbits per
sec, which should be enough to carry 2--2.5 Mbits per
sec for the media stream</li>
</ul>
<p>OBS knows how to stream to other broadcasting services,
so now I have a few other alternative to investigate:</p>
<ul>
<li>Twitch (apparently popular with gamers: rather than
playing, you can watch others play)</li>

</ul>
<p>Thank you for the pointer to broadcast services: I
thought there must be some available, but was obviously
searching for the wrong thing.</p>

<div>We have a family celebration
coming up in January, and want to be
able to provide a live audio and
video stream from the event for
people who cannot be there.<br>
<br>
</div>
I have the following available:<br>
<ul>
<li>Video camera with microphone
input, microphone, and AV capture
device that are compatible with
V4L2</li>
<li>Laptop running Ubuntu 14.04
desktop<br>
</li>
<li>Mobile data modem</li>
<li>Low-spec VPS (2 core, 4G RAM, 1
Gbps network connection, 5 TB
bandwidth per month) running
Ubuntu 10.04 server<br>
</li>
</ul>
<p>The plan would be for the laptop to
capture the audio and video which
will send it to the server. Absent
family and friends can then connect
to the server, preferably using a
web browser, to watch the
proceedings. There will probably be
4 or 5 families watching from around
the world.<br>
</p>
<p>Some rationale:<br>
</p>
<ul>
<li>I prefer the video camera,
microphone and capture device to a
web cam because it should give
more control over the picture and
sound quality.</li>
<li>I prefer the video camera,
microphone and capture device to
an IP cam because I don't want to
spend the money.</li>
<li>I don't want all of the guests
connecting directly to the laptop,
as all their traffic goes via the
mobile data modem -- I suspect
costs will mount up quickly,
though I should estimate what it
will cost.<br>
</li>
</ul>
<p>Now, VLC can capture the video and
stream it to another instance of VLC
using a few different protocols. I
have not had success with the audio
yet, but it might just need to swear
at it a bit more.</p>
<p>Motion and ZoneMinder might be
appropriate, but ZoneMinder does not
support audio.</p>
Can anyone offer any advice, before I
spend days playing with things: what
software to use, what to avoid, what
have I not thought of, will my
low-spec VPS be adequate to server 5
streams, any other thoughts?</div>
