Video quality on high resolution
Hello
I have installed Openmeetings 1.9.1 r4707 on Linux 2.6.39-gentoo-r3
i686. It works fine except if I change camera resolution to 640x480 or
higher. After this video becomes slow and I see "slide show".
Window which shows local camera output is OK - no delays.
Computers (clients) and server are inside same LAN and have 100M or 1G
connection. Network speed is not an issue definitely.
CPU load is not problem too - I have Intel CPU with 2 or 4 cores.
Do you have any ideas how to fix the problem?
Thank you.

And by the way: Following your link to the takedown notice does lead to a
website about illegal downloads of TV-Series that are done using rtmpdump.
What we do is not a tool to download random rtmp streams that could be used
for downloading TV-Series. So I don't see how you can build a claim based
on the article and takedown notice that would affect us or anyody else that
read or writes RTMP packets.
[I am still no lawyer though :)]

Re: Video quality on high resolution
Posted by "seba.wagner@gmail.com" <se...@gmail.com>.
Your article is from 2009, I think in the meantime things have changed.
https://issues.apache.org/jira/browse/LEGAL-120 also is discussing RTMP
license issues (although more discussing the specs AS-IS).
However, writing the stream to discuss has nothing to do with the an RTMP
specification document in fact.
What you do is simple take the packets that you receive and write them to
disc.
I personally have never read the RTMP specs anyway, but I was able to grab
the stream and write packets to disc.
The issue about the RTMP spec from my point of view is more likely the
following:
The RTMP spec contained (or does still contain) portions that say: If you
read this spec you agree on NOT doing this or that.
That is why some linux developers working on Flash player clones always
claim to "never read that spec" but rather understood it by just looking at
the raw bytestream.
Or for example the motivation of websites like that one:
http://osflash.org/documentation/rtmp is to have a public, by reverse
engineering produced specification that does NOT rely on reading Adobe docs.
I am not a lawyer, but from my point of any specs really can't prevent that
any user on any device that somehow "randomly" reads packets on his eth0
device or by using tools like Wireshark reads those packets and analysis
what parts they consist of.
What those RTMP specs say (and is seen criticial is) the part where Adobe
claims: By *reading *the specs you agree on certain terms.
However even the reading might be not so critical anymore since Adobe has
applied some major changes on their position again Open Source.

As for recordings, AFAIU, server side recording would have legal problems,
see [1]. I'm not a lawyer to say that for sure.

Re: Video quality on high resolution
Posted by Alexei Fedotov <al...@gmail.com>.
Hello George,
1. I didn't record things, I've tested standard 1:1 videoconference setup.
2. I had maximum resolution of 1024x768. It seems the bandwidth is limited
by 1,2 MBit/sec, probably by flash player. I got even lower frame rate, and
bandwidth didn't grow.

RE: Video quality on high resolution
Posted by George Kirkham <gk...@co2crc.com.au>.
Alexei,
What difference does it make if you are recording at 1920x1080 (the current HD standard).
I can see an advantage with server side recording as long as it does not burden the server so that it cannot support the users. The ability to record is not that important to me as to get “the ability for users to have a meeting” working smoothly. The issue of managing different screen resolutions is a challenge to me.
Thanks,
George Kirkham

I've made some research on the peak bandwidth usage by opening two browser
windows.
640*480 1,2 MBit/s (the rate is still below 30 frames per second, setting
<bandwidthNeededNormal>0</bandwidthNeededNormal> improved things a bit)
432*240 0,8 MBit/s

Just want to share the method. I've opened two browser windows (that gives

If you're running on a LAN and BW is not an issue have you tried setting this
<bandwidthNeededBest>0</bandwidthNeededBest>

Hi Lawrence,
We are using RTMPS over HTTPS and all is working as expected, only issue
we are having is with the screen sharing + recording, it doesn't seem to
be working in the latest snaps but I believe this is being looked at.
I can't say we have seen any reduction in quality or slow down using
encryption but I haven't loaded it up that high, I'll run some tests and
see if it's the same here and let ya know.

Thank you for reply.
I have installed VP8 codecs and they improved quality a little. But it
is still not ideal/expected.
I assume, at the moment I have no other solutions, right? Can SWF10/11
improve situation? When are you going switch to it?

There is no way to specify other codec for OM.
please search dev mailing list, there will be no other codecs until we
switch to SWF10/11

Thank you.
Do I need remove previously installed codecs or how can I tell
OpenMeetings to use codec below?

That's known flash issue. As for now we don't have a workarond. Some
possible options include upgrading flash (in our build) or migrating to

Thank you for the suggestion. I will try tomorrow and let you know result.

Well, I test this on standard clients - they need video mostly.
In conference room we will nave 4 cores CPU and this should not be an issue.
I will make more tests tomorrow and let you know exact details.
Btw, I used Logitech HD Pro Webcam C910 for tests + laptop integrated
camera. Both cameras have same issue.

Re: Video quality on high resolution
Posted by "seba.wagner@gmail.com" <se...@gmail.com>.
The server should be no issue at all, with 1 or 2 clients no matter what
JVM settings you choose.
You could try to use OpenMeetings integration screen capture to record the
meeting streams.
The recorded "raw" streams video material is in
webapps/openmeetings/streams/$ROOM_ID/ *.flv
=> You could check if the recorded raw camera file is already "slow-mo" if
yes the issue is somewhere on the publisher side, if not the viewers just
simply can't watch such high-resolution video properly.
60-70% of cpu is not an acceptable rate.
That is just too much, you can't make a permanent conference about 1 hour
with that load, you might also need some CPU leftover for someting else
like editing whiteboard et cetera.

Btw, as I told, local camera output seems fine even on 640x480 or higher
resolution. The problem in remote camera only. I tested many client
(computers) but the issue present on all of them.

I can not tell exactly now because one camera is integrated in laptop
and 2nd camera in office.
I'm reviewing option to buy Cisco camera. It costs ~$500 but I'm not
sure if it can help...

On 2 cores - ~60-70% (Win task manager)

Does yoru webcam support more then 640x480 at all? Most webcam'S max
resolution is 640x480.
*CPU load is not problem too*
=> have you really checked that or just assuming? How much % of your CPU is
the application "eating" on both client that acts as publisher and as
viewer in your conference?
