I-Caster

Evaluation version 3.02 build 1051

Mail of July 1st, 1998: 

How do I make a new default 'Broadcast ID...'  in I-Caster?

Furthermore I want to use Broadcaster in a standalone environment. Say I had once started the broadcaster and it determined an IP multicast address of the session. But after a long power down, the IP broadcast address is used by another session. It is then possible that Broadcaster just choses a new multicast address without asking for an ack. of the user (remember because it is unattended, there is no one to say 'OK' ;-)

Why is the CPU load so high compared with vic?

It is to difficult to find the multiple video windows of the participants in a Mbone sessions. The user interface should be improved on this.

ISpy

ISpy 2.00

Mail of Febr. 11, 1999

I now have sometimes the problem that if I have 3 ISpy's running, a picture can have a thick black line in it (like in former times on the television). See the attechment.

This is not the case if I am using the web camera program of my drivers (Winnov, and also three camera working in parallel). Is this problem solvable in ISpy? It also exists if I put the Ispy's in the 'no preview' mode.

With NT4.0 the video overlay is not working nicely, sometimes the pictures is still in the old location even after moving the Media Player window. With Windows95 no problem.

Mail of Nov. 13th, 1998

Why do I get the message: "No audio data has been sent from the input device for multiple seconds. Typically, this indicates trhat the audio capture devicxe driver has failed." If I am not interested in audio (I only have video to be encoded)!

NetShow server keeps the conection of ISDN open due to polling of the encoder (the time out of ISDN does not work anymore).

  • the last letters are going past the right margin (so yo have to guess them). See also my mail on August 31st,1998 about different margin between sun and PC. (not retested this with s31 yet)
  • When an active tool is minimized, you only see the title of the session, but not what tool is there, so trying to find the right tool is a pain in the neck (you have the click on everyone to see if it is the right one). Perhaps you should put the tool name in the beginning of the string, like you do for sdr.
  • the backspace (del works) does not work in the 'Set Encryption Key' window
  • the name is not correct: 'Victor Reijs (SURFnet bv)@site2.knowth.surfnet.nl' it is not using the SDR info.

    Multicast (if it is working!) is working not very user friendly. At this moment we don't see multicast even working together with RealPlayer (problems with the ra.sdp file).

    Version 6.0.3.271

    Mail of June 25th, 1998:


    Hello support,
    I would like to be able to run RealPublisher
    on a standalone machine (so a machine were no
    people are available to push/click buttons).
    Also the power can go down once in a while.
    What I would like to do, is put RealPublisher in
    the Startup directory, so that at start up Real
    Publisher is started automatically, but in that case I need to be able to provide a schedule to RealPublisher. Like what time, date, day of week, etc. (if needed I could provide a gif of the windows which needs to be filled in for such a schedule).
    Some examples of such a scheduler can be seen
    in: a) ICAST broadcaster, b) sdr-tool and c) webcam programs (like Ispy).

    Is it possible to provide such a function? I need this for broadcasting live over the Internet the sunset at a megalithic building (Maeshowe) in Scotland (http://maeshowe.myapge.org/).
    This is a project to be sponsored by SURF-ACE (http://www.surfnet.nl/ option: projects)

    Hope to hear your response.

    version 2.5.6

    Mail of Oct. 16, 1998


    I took a look at this, and it turns out that
    there's a bug in the version (2.5.6) of "sdr" that you're currently using
    to generate this announcement: it's ending each line with <cr><lf>, in
    violation of the SDP spec.  (Lines are supposed to end only with <lf>.)

    Nonetheless, the next version of multikit will be able to accept
    announcements like this.  In the meantime, you can update the version
    you're currently using by making a small change to "mk_sap_watcher.tcl".
    Change the line
            set packetData [split $packetData \n]
    to
            set packetData [split $packetData \n\r]

    However, you should probably use a different version of sdr to make your
    announcement, otherwise some others out there won't get to see it.

    It is a way to do it, but not really user friendly. Hope it could be
    changed in a more easy way.


    Mail of November 4th, 1998

    It seem to have a strange problem. Opening a file (atreussky) in  SkyPaint (1.08) and directly 'save' it; I get the error message from SkyPaint: 'IO error opening c:\Terrain\atreussky*_FRG"
    The only way to save is, is give it a new name.

    I assume that that is not the way to do it;-) What do I do wrong?

    Spazz3D

    Version 12.3


    Mail of Jan. 8th, 1999


    Hello Spazz3D,

    I have been using your program to edit an old VRML file (made by VRMLshop and then through the vrml1tovrml2 program). I have attached the VRML file coming out of Spazz3D. When I pass this VRML file through the VRML2POV program, I get error messages that the VRML file holds "triangle with two vertexes at the same point" (so a kind of one dimensional polygons).
    I understand from the author of VRML2POV that this should not be a normal output of a VRML program.

    My question to you is now; do you know why Spazz3D generates these 1 dimensional polygons and is it possible to remove this behaivoir?

    More information on the errors can be gotten perhaps from Paul Thiessen (see cc-line).

    This mail is also putten on my general bug/feature page:
    http://www.iol.ie/~geniet/eng/bugs.htm
    Hope you can help me with this.

    >We have this sort of access control supported in the ISDN ASCEND box.

    That is indeed one way to do it, but now your UTG server
    (utg.cs.ucl.ac.uk) for instance is reachable and usable by all over the
    world (at least SURFnet). So I think that not only at the WAN gateway
    level (which is, the ISDN gateway you have, correct?), but also at the
    server level you need some kind of admission control. I think that
    having adddimision conctrol for A service is better then at another
    (lower) level.
    I know that getting real authentication is too much to ask (at this
    moment). But providing the server with some host/networks access list is
    a simple start in my opinion (and an essential function).

     >We do plan to put in both some form of access control, form of dealing
    with encrypted sessions, and some form of access conrol for managers.
    >
    > These will all be in the future.

    But a simple straight host or network list, is a minimum I think (like
    done in liveGate).

    The height in VRML is always relative to the 'min. height' in the terrain. Perhaps it would be better to have the absolute height in VRML.

    Mail of August, 15th, 1998


    If I save a file and then I import a (in my case an xyz) file, then using 'save' does not ask for a new name, but it overwrites the earlier one. I was happy to have still the xyz file, otherwise I would have lost my work... So if you import a file please let the program ask for a new name. (see also my mail of March 28th, 1998)
    Furthermore is it possible to put the name of the file in the 'blue upper part of the window' like in all other winodws programs?
     

    Mail of March 19th, 1998


    . the "background color" in the VRML window is not handled well. Say I
    have a yellow background; If I click the "background color" button and
    directly go back with "ok" (without changing the color by myself), I get
    the default color [black], in this case it should stay the same.
    . could you change the scaling in the VRML window to % instead on the
    present figures. The default INTERNAL scaling is for vertical value 1
    (equal to 100%) and 'Grid spacing' for horizontal (equals 100%).
    Let the user then define the scaling factor in % on these basic INTERNAL
    scaling factors (that make this consistent with the scaling factor in
    'animator'.

    I never use any word/extenstion/direcotry-name/etc. like 'tin' (after
    checking the resulting file I see from the content that it is a tin
    file, nothing more).

    the wrl file is called: maes.wrl
    Instead of the normal path, I use the path:
    c:\www\demon\maeshowe\pic\
    if I sent it to c:\www it is oke, but any other sub directory makes a tin
    file (c:\www\demon\, c:\www\demon\maeshowe\)
    c:\tmp\test and c:\tmp\test\test though work oke...

    Do you understand this???

    Mail of March 25th, 1998


    A small change to the camera position (this is better and less dependent
    on size of terrain):
    Viewpoint {
    orientation -1 0 0 1.57
    position "half of max. x" "2* Mx of (half of max. x) and (half of max.
    y)" "half of max. y"
    description "Bird view"}

    An example:
    Viewpoint {
    orientation -1 0 0 1.57
    position 10000 30000 15000
    description "Bird view"}


    Mail of March 28th, 1998

    When quitting the program Terrain you now ask to save the changes, but
    you also should do that when 'new' and 'open' are clicked!

    Mail of May 19th, 1998


    I am again starting to use your program (a new project of the Treasury
    of Atreus, Greece). For that I again try to get the terrain in the
    'Generate fractal overlay' but that does not work. Even when using the
    'terrain' box in 'Map' tab. I have the file attached.

    Can you provide a hint?

    Mail of May 19th, 1998


    I am using Visual Terrain, I have some difficulty with the definitions
    of the angles (fractal generation and I assume also thus in Visial
    Animator):
    . it seems you have the 'altitude degrees' right of the 'azimuth circle'
    (the same yields for the 'azimuth degrees' right of the 'altitude semi
    circle'). You have to swap them.
    . what is your definition of altitude? When looking at the position of
    the sun, the altitude is seen from the horizon (while you do it from the
    zenith)

    Or are there other angle definitions in rotation?

    Videum 2.7 RC6 drivers


    Mail sent on Febr. 7, 1999

    Oke, I am now using the last option you mention; so on a Windows95,
    Pentium I, 200 MHz, Videum AV, driver 2.7. I am using three camera's.
    If one camera is NTSC (the other two are PAL) then this causes sometimes
    synchronisation or color errors in all of the pictures. If I use three
    PAL cameras, the problem does not exist. So there is the workaround;-)
    But is it possible to change this behaivoir?

    The other problems I have with using multiple webcam's (using your
    caputure program) are:
    . is it possible to start and stop the webcam at predefined moments.
    . is it possible to save the ftp/camera/timer-info per webcamera. It
    seems it can only remember one. There should be some 'save configuration
    option'
    . it seems that sometimes the webcam is writing the jpg-file and at the
    same moment a browser wants to read it. This is not possible of course.
    But could you chance the behaivoir of the webcam: first saving the file
    with a dummy name and then renaming it on the remote system to teh
    correct name. This minimize this problem.

    Thanks for your feedback.

    My test page is at:
