FLV Encoding at 640x480 & Frame dropping

Hi List,

We've been frustrated with our client trying to bring the
best smoothest
experience of playing video at 640x480 (stretched to
fullscreen). Does
anyone know what exact encoding settings for a movie with a
lot of motion,
to play fullscreen at that resolution without stalling and
dropping frames ?

I am streaming over FMS, got the latest updates for FMS,
FLVPlayback and
Flash Player.

 I know FMS drops frames when the bandwidth is
insuffiecient, and I know it
favors Audio then netstream calls and then it may drop video
frames based on
whats left of the bandwidth.

But if I even encoded at 640x480 with NO audio at all it
still drop frames,
we're currently using On2 VP6. Should we try Sorenson ? Any
ideas PLEASE
help !

Thank you
Yehia

I'm kind of disapointed :

but :
trace (9.3-9) // traces: 0.300000000000001
trace (100.3-100) //traces: 0.299999999999997
...
is there a way that it can traces always 0.3 has it should
be normal ?

Hi,
multiply everything with 1000 before, and divide by 1000

Short answer: that's expected, happens with every language,
use rounding 
if you need, etc.

hello 

the float number are a problem in Actionscript 

you can read this article
http://en.wikipedia.org/wiki/Floating-point_numberabout this problem.

If you want fixed this problem you can use the NumberUtil
class of my
openSource framework VEGAS :

1 - the page of the project to download the AS2 : framework
http://vegas.riaforge.org/


2 - Use  a Subversion(SVN) client to download the framework
or download the
zip

3 - install the classpath ol vegas in your flash IDE in the
preference ->
ActionScript2 preference ... add the AS2/trunk/src directory

4 - Use the NumberUtil class, example :

import vegas.util.NumberUtil ;

var result = Number(NumberUtil.toFixed(9.3 - 9, 1)) ;
trace(result) ; // 0.3

var result = Number(NumberUtil.toFixed(100.3-100, 1)) ;
trace(result) ; // 0.3

EKA+

I did a small quiz for a client and now they've decided to
make it integrate 
into their LMS. I did some looking and it seems using
external interface and 
calling the LMS like so:
ExternalInterface.call("LMSInitialize"); should 
work pretty well. However two things are not making sense to
me. I see how I 
can call LMSSetValue to set the users score but I only see
min, max, and raw 
score entries. The quiz has 21 questions, can I not track
the response for 
each question?
Finally, this quiz has a bunch of associated FLV's - 50MB
worth. Can the 
video content be kept outside of the SCO package? Does it
need to be 
included in the manifest XML file? I thought I could just
place the flvs on 
their server and reference them from Flash... that's what I
was hoping.

Thanks for any insight.

If you're doing a financial application, it's important that
you address
this correctly: fast but giving the wrong answer isn't an
option.

I have worked on some systems where the front end gave one
figure, but the
back end reporting function gave another because this wasn't
properly
addressed..

As a financial application developer, it's surprising you
weren't already
aware of the inaccuracy of floating point.

Knowledge of arithmetic would seem to be the sort of thing
one would 
expect in a financial "expert". 

Although to be fair, this does crop up about once a quarter
in the forum 
as a new person discovers one of the hidden joys of using a
computer 
that does not have 10 fingers to work with.
