0.8.2 is this the version you are using ?

yes but if you have ugly squares every where that means that the 
image is not decoded properly

 because usually codecs divide the image in sections and reconstruct 
 it by multiple phases from bigger grain (bigger square blocks) to 
 smaller (pixels). So my suspicion on the failure on the codec part. 
 It maybe a problem of not receiving enough data (frame drops or pkt 
 drops), or problems with jitter and interleaving.

maybe the support for shoutcast video stream is not optimal yet

with winamp and win2K it's quite good  ;)

Or maybe a very bad implementation.  Don't know enough about Shoutcast 
/ VLC combo to know more.

but not every one can use this I know

Yes version 0.8.2

I will go with Shoutcats if I see a benefit. So far I don't see one.

yes I understand I'm a win user for win/linux environnement it's 
quite good to use shoutcast but maybe MacOSX tools are still too 
young

We need platform coverage, real-time archiving and real-time broadcasting, 
broacast relaying, easy setup, low bw, and high quality.

A set of requirements which is quite demanding.

I think features such as subtitile, special effects, multiple input 
(cameras, files), comes second in priority.

hum yes but can be good especially to add special subtitles to point 
to key information

(Leaving now I already polluted this channel too much)

what  shows me last year is that the quality of the audio/video retransmission 
was really poor ...  but maybe that was hardware problems

lol

bye

I have hear that part of the problem, last year, was the upstream 
bandwith form the Hotel : quite low ?

shadwolf: the problems you describe are due to packet loss, and would 
be EXACTLY the same both on shoutcast and QT.

anyway, i don't see any mention of video broadcast in the shoutcast 
home page.

we had two problems with QT last year: first one, on the first speech 
the audio codec was not set up correctly. this was fixed later on. 
second, we had to resort using the mic on the camera (which is a 
cheap camera after all...), and of course the lighting in the room 
was not good at all for a camera (it was dark to allow us to see 
the slides)

other than that, the streaming cannot get any better unless you really 
have very good BW

if Jaime can bring his laptop this year too, i think we can still 
use QT as it was already proven to work. also, if we manage to have 
a second camera, i'd like to have a high quality recording (on tape 
maybe) that can be encoded later for best quality.

the wireless mic I bought for the PA system at the conference ended 
up having a bad lapel mic, and testing the system revealed to me 
that the earpiece was actually a better mic (  strange, but true 
) but no one else knew that, so the first speech did not have the 
PA working, because the Lapel mic was used instead of the earpiece.

i think that if the school gives us their media room we'll have their 
equipment too (not sure how much of it they would make us use though)

i guess we can at least have good mics. otherwise, i'll just buy 
something and test it before the devcon.

The screen in the room was highly reflective, a plastic, which gave 
a bright spot..so angling the cameras better, or a non-reflective 
screen would help.

anyway - we didn't have many people watching the stream actually 
last year. less than 5 or so. so it's higher priority to me having 
good recordings to offer after the devcon.

I only brought 1 tripod, and I should have brought 2.  So the camera 
I had, I had to hand-hold, and with the Hotel coffee, my hands were 
shakey...;-)

(just dumping out some past mistakes so none get repeated...;-)

I will not be able to make it to DevCon2005... but here's my input.


It will be good if 'virtual audience' can have access to the speakers 
papers or presentation maybe the night or even as they are presenting.


That way.. we can listen and digest from the presentation on hand...

One option is to provide commentary text, images and links a few 
seconds after they are shown.

For synchro skating competitions that we can't attend, we follow 
them using Team Germany's Live Ticker.
http://www.teamberlin-1.de/live_frame.php?ev=2&lang=en

This is a very slick PHP application that has photos taken at the 
arena and broadcasts them  a few seconds later.

Some dedicated fans from Germany were providing the photos (JPEGs), 
scores and bilingual (at least English and German) commentaries.

When new content is published, a message appears at the top to inform 
the viewer that it is available.

They hit the refresh hyperlink and they are up-to-date.   From the 
timestamps, our lag time to Canada was sometimes as low as 45 seconds 
after the event occurred i.e. we are getting commentary results about 
a given team's skating while they are still on the ice.

This site reports http://www.teamberlin-1.de/en/cup-of-berlin/that 
4,000 viewers followed the Berlin Cup in Jan-2005 using Live Ticker.

Maybe something like that would work for DevCon2005.

Is there a list of participants online (or where there be one)?

May I suggest someone (Gregg, you) do a short one on Roxy

good idea! Gregg would be best, but i could do a quick intro...

they prefer to comunicate on audio layer but video exist too with 
shoutcast but then video seems to doesn't work properly with MacOSX 
clients (VLC ...) I have no objection to use QT but It would be nice 
to first test the reability of shoutcast witch have been done and 
witch gives us the known result ...

before the end of next week, i need to have a rough idea of how many 
persons are interested in the "visit rome" plan (see http://www.colellachiara.com/devcon05/register.html); 
it would be good to have an idea of how many persons need an hotel 
room in milan too - if you don't tell me, you'll have to work this 
part out by yourself then.

Gabriele we are actually collection this information for french scene 
...

we will give it to you asap

My friend who is big fan of F1 racing today informed me, that 2nd 
of October, there is F1 racing in Milano? He also told me, F1 is 
rather popular in Italy, and that we should expect Millano traffic 
troubles starting from 1st of October. Gabriele?

Ouch.  funny how racing slows things down.

Monza "Grand Prix" is 2, 3 and 4 september. So if any, it's not formula 
one at this date.

Yep, DideC is right. See www.formula1.com.

so there is no "race" condition?

As you see I got a slot but no topic yet... I have some ideas, but 
I'm not sure what you are interested in most. So, hey, why not ask? 
:-))

Ok, ideas I have are:


1. Is commercial success of Rebol bound to open-source the interpreter?
2. make-doc-pro browser as a base for an IOS/xpeers based Wiki
3. The RPC idea - 12 months later


If you have an other idea let me know :-)) I'm open to think about 
all kind of topics.

I like (1).
