FFmpeg is an audio/video streaming server for Linux suitable
|
|
for live<br>
|
|
broadcasts. It supports real time audio/video compression in
|
|
several<br>
|
|
formats (mpeg, mjpeg, real, flash, asf) and bitrates at the same
|
|
time. A<br>
|
|
soft VCR is also included.</p>

Port of FFmpeg to the Quicktime architecture, currently
|
|
capable of<br>
|
|
decoding various MPEG-4 and MSMPEG-4 variants, including DivX,
|
|
XviD and<br>
|
|
3ivx. Support for Huffman YUV, WMA & AC-3 is planned. DivX

MPEG4IP: Open Source, Open Standards, Open Streaming</p>
|
|
|
|
<p>MPEG4IP provides an end-to-end system to explore MPEG-4
|
|
multimedia. The<br>
|
|
package includes many existing open source packages and the
|
|
"glue" to<br>
|
|
integrate them together. This is a tool for streaming video and
|
|
audio<br>
|
|
that is standards-oriented and free from proprietary protocols
|
|
and<br>
|
|
extensions.</p>
|
|
|
|
<p>Provided are an MPEG-4 AAC audio encoder, an MP3 encoder, two
|
|
MPEG-4<br>
|
|
video encoders, an MP4 file creator and hinter, an IETF
|
|
standards-based<br>
|
|
streaming server, and an MPEG-4 player that can both stream and
|
|
playback<br>
|
|
from local file.</p>
|
|
|
|
<p>Our development is focused on the Linux platform, and has been
|
|
ported to<br>
|
|
Windows, Solaris, FreeBSD, BSD/OS and Mac OS X, but it should
|
|
be<br>
|
|
relatively straight-forward to use on other platforms. Many of
|
|
the<br>
|
|
included packages are multi-platform already.</p>
|
|
|
|
<p>This code is not intended for end users, and does not
|
|
contain<br>
|
|
executables. Please read all the legal information to determine
|
|
if it is<br>
|
|
suitable for you.</p>

Darwin Streaming Server</p>
|
|
|
|
<p>What is the Streaming Server? Streaming Server is server
|
|
technology<br>
|
|
which allows you to send streaming QuickTime data to clients
|
|
across the<br>
|
|
Internet using the industry standard RTP and RTSP protocols. It
|
|
is based<br>
|
|
on the same code as Apple's<br>
|
|
QuickTime Streaming Server.</p>
|
|
|
|
<p>Darwin Streaming Server 4.1.3</p>
|
|
|
|
<p>Welcome to Darwin Streaming Server 4.1.3, the streaming media
|
|
server<br>
|
|
that combines industrial strength performance with engaging ease
|
|
of use.</p>
|
|
|
|
<p>Darwin Streaming Server 4.1.3 provides a number of
|
|
security<br>
|
|
enhancements.</p>
|
|
|
|
<p>Features include:</p>
|
|
|
|
<p>QuickTime Broadcaster Remote Administration: Now you can
|
|
control<br>
|
|
QuickTime Broadcaster remotely via the administration interface
|
|
of<br>
|
|
QuickTime Streaming Server 4.1.3 when both are installed on the
|
|
same<br>
|
|
machine. Start and stop broadcasts, select audio and video
|
|
settings, and<br>
|
|
more. Note: This feature only works with Mac OS 10.2 ("Jaguar")
|
|
and<br>
|
|
later.</p>
|
|
|
|
<p>Instant-On Streaming: Instant-on dramatically reduces the
|
|
delay caused<br>
|
|
by buffering of the media stream prior to playback, allowing
|
|
broadband<br>
|
|
users of QuickTime 6 to begin watching streaming media, both on
|
|
demand<br>
|
|
and live, right away. With Instant-On, broadband users can also
|
|
"scrub"<br>
|
|
forward and back with the time slider through an on-demand media
|
|
stream<br>
|
|
and have playback updated instantly.</p>
|
|
|
|
<p>MPEG-4 Support: Now you can serve ISO-compliant hinted MPEG-4
|
|
files to<br>
|
|
any ISO-compliant MPEG-4 client, including any MPEG-4 enabled
|
|
device<br>
|
|
that supports playback of MPEG-4 streams over IP. You can
|
|
serve<br>
|
|
on-demand or live MPEG-4 streams, and reflect playlists of MPEG-4
|
|
files.</p>
|
|
|
|
<p>MP3 Streaming: You can serve standard MP3 files using
|
|
Icecast-compatible<br>
|
|
protocols over http. Build a playlist of MP3 files and serve them
|
|
to MP3<br>
|
|
clients such as iTunes, SoundJam and WinAmp for a simulated
|
|
live<br>
|
|
experience.</p>
|
|
|
|
<p>Skip Protection: Skip Protection uses excess bandwidth to
|
|
buffer ahead<br>
|
|
data faster than real time on the client machine. When packets
|
|
are lost,<br>
|
|
communication between client and server results in retransmission
|
|
of<br>
|
|
only the lost packets, reducing impact to network traffic. By
|
|
buffering<br>
|
|
ahead a high-quality "copy" of the media, QuickTime Streaming
|
|
Server<br>
|
|
delivers a high-quality media stream time after time.</p>

Camserv is a free program to do streaming video through the
|
|
web<br>
|
|
Streaming video can be sent to both Netscape and Internet
|
|
Explorer<br>
|
|
clients. However, Internet Explorer under Windows cannot
|
|
apparently<br>
|
|
handle the multi-part JPEGs, and therefore a special javascript
|
|
page<br>
|
|
must be setup. One is included in the distribution as an
|
|
example.</p>

MEC4 is a Video On Demand Streaming Server based on a
|
|
multithreaded<br>
|
|
architecture and running on the Linux Operating System. The
|
|
server can<br>
|
|
handle multiple concurrent streams which it delivers by mean of
|
|
a<br>
|
|
proprietary simple protocol called CMTP (or SSP/MSP).
|
|
"Proprietary"<br>
|
|
means that we created it and it works well for our purposes. The
|
|
server<br>
|
|
is under development and, although stable enough for testing, I
|
|
believe<br>
|
|
it must be considered in a beta stage. Note that it needs glibc2.
|
|
Main<br>
|
|
features are:</p>
|
|
|
|
<p>* Unlimited number of concurrent streams (the hardware is the
|
|
only<br>
|
|
limit).<br>
|
|
* Throughput up to 2 Gbit/s per server.<br>
|
|
* Extended clustering capabilities with unlimited number of
|
|
servers<br>
|
|
in the cluster.<br>
|
|
* Very simple but effective streaming protocol: SSP/MSP.<br>
|
|
* Extremely tunable.<br>
|
|
* User validation based on IP address and permissions.<br>
|
|
* Per user file access control.<br>
|
|
* GPL.</p>

<p>It's safe to say that it's not ready for production use. We've

been<br>

updating the ogg infrastructure for it, and my guess is that

|
|
|
|
<p>On the icecast side, there has been little work if any on

it<br>

probably wouldn't be very hard.</p>

<p>To my knowledge, Real is still the best thing you can do for

is cross platform. They support multiple arches of linux as well,

<p>An interesting offering. Of course, those of us who've

rather unpleasant history of Real Networks, Inc. will have

predicted the<br>

agreement.</p>
|
|
|
|
<p>Summary: You may install it only on two computers and use it
|
|
only on<br>
|
|
one machine at a time. Real Networks can modify this licence in
|
|
any way<br>

it pleases, with fourteen days' notice. You're allowed to
|
|
develop<br>
|
|
software that talks to Real Networks's ActiveX interfaces, but

|
then may<br>
|
|
not distribute your own software without Real Networks's

|
separate<br>
|
|
permission. You may not redistribute the program. You may not<br>
|
|
reverse-engineer or modify it.</p>
|
|
|
|
<p>You must be in compliance with export laws and not associated
|
|
with<br>
|
|
countries the USA considers naughty, like Cuba. You mustn't be on
|
|
the<br>
|
|
USA Treasury or Commerce Department's lists of naughty people
|
|
(drug<br>
|
|
smugglers, terrorists, export-regs violators, etc.).</p>
|
|
|
|
<p>You may not use the program in a DMCA-style "circumvention"
|
|
manner. You<br>
|
|
may not attempt to circumvent the built-in "serial copying
|
|
management<br>
|
|
system". You may not develop software that can be used to stream
|
|
or<br>
|
|
export your Real Networks-encoded data to any other format, or
|
|
that<br>
|
|
generates live-transmitted Real Networks-encoded files.</p>

<p>I infer that calling your clients' attention to particularly

there.</p>
|

<p>Anyhow: One very hot button for corporate decision-makers is
|
|
inability<br>
|

to control business risk. From that perspective, software that is
|
|
prone<br>
|
|
to incompatiblity-inducing changes outside the company's control
|
|
is an<br>
|
|
uncontrolled risk. Software whose licence can be unilaterally
|
|
withdrawn<br>
|
|
or modified at will by the other side, with no discussion and
|
|
only<br>
|
|
fourteen days' notice, is an uncontrolled risk. Software whose
|
|
licence<br>
|
|
authorises the other side collecting unspecified private
|
|
information<br>
|
|
about the inner workings of the company is an uncontrolled
|
|
risk.</p>
|
|
|
|
<p>And: An executive who allows his company to becomes dependent
|
|
on<br>
|
|
software he is not allowed to see inside, let alone change, has
|
|
lost<br>
|
|
control of his business, and is on the wrong side of a

|

relationship with a vendor who can thereby control his

|
|
|
|
<p>Employee training sounds to me like a perfect test case for
|
|
MPEG4IP,<br>
|
|
given the company's IT control over both client and server ends.
|
|
But of<br>

<p>Actually, performance really rather sucks (by most measures)

compared to<br>

some of the competition. MPEG4IP, for example, uses Apple's

<p>Sorry to hear that you've missed three years of news: Darwin
|
|
Streaming<br>
|
|
Server runs on pretty much any *ix platforms. It was ported to
|
|
Linux<br>
|
|
within (if memory serves) less than 24 hours of its initial
|
|
release, a<br>
|
|
couple of years ago, at the time that Apple open-sourced it and
|
|
Darwin<br>
|
|
itself.</p>
|
|
|
|
<p>Naturally, it runs a great deal faster on Linux, FreeBSD, and
|
|
Solaris<br>
|
|
than it does on MacOS X Server.</p>
|
|
|
|
<p>E.g.: <a href=

|
<p>I must say, Chris, you seem to have suffered from a great deal
|
|
of very<br>
|
|
bad advice. First, somebody mislead you into believing, in error,
|
|
that<br>
|
|
Darwin Streaming Server runs only on OS X -- which a
|
|
twenty-second<br>
|
|
Google search would have shown is not the case -- and then you
|
|
got<br>
|
|
the "IT Comparison" from that university guy, and following that
|
|
the<br>
|
|
"security expert" bloviating about system security.</p>
|
|

|
|
|
|
<p>If you'll look at the way it's implemented in the MPEG4IP
|
|
architecture,<br>
|
|
you'll see that it handles numerous codecs and data formats
|
|
simultaneously.<br>
|
|
It doesn't handle numerous _streaming_ formats simultaneously
|
|
because it<br>
|
|
doesn't need to: Either RDP/UDP or RTP/RTSP/TCP (per the
|
|
deployment's<br>
|

requirements) accomplishes all that the server has to do.</p>

proprietary extension of H.263 -- which is exactly as I said.</p>

proprietary<br>

<p><sigh> It's the same code. The distinction is solely a

Darwin Streaming Server otherwise. You can see that for yourself,

|
|
|
|
<p>Q: Does Darwin Streaming Server have the same features as
|
|
QuickTime<br>
|
|
Streaming Server?<br>
|
|
A: Yes. While there are inherent performance differences as a
|
|
result<br>
|
|
of the platform, all versions have the same features.</p>
|
|
|
|
<p>They're saying that they use platform-specific compiler
|
|
optimisations,<br>
|
|
in compiling the PPC-binary version that ships with OS X Server,
|
|
plus<br>
|
|
they probably put a spiffy label on the box that says
|
|
"Apple<tm><br>
|
|
QuickTime<tm>". Otherwise, no difference at all.</p>
|
|
|
|
<p>Quoting the same page:</p>
|
|
|
|
<p>QuickTime Streaming Server, while designed for Mac OS X
|
|
Server, is<br>
|
|
also available via the Darwin open source project, which offers
|
|
a<br>
|
|
high level of customizability to just about any network. Sharing
|
|
the<br>
|
|
same code base as QuickTime Streaming Server, ready-made versions
|
|
of<br>
|
|
Darwin Streaming Server are available for Linux, Windows, and<br>
|
|
Solaris. In addition, since source code is available, it can
|
|
be<br>
|
|
ported to most any platform by modifying a few files.</p>
