Topic: Download Progress Meter

The Silverlight version has a "Loading..." meter that shows the download progress in percentage. For big synths, this is very handy, especially when the synth file takes over 3 or 4 minutes to download and currently it displays only blackness so the user does not know whether the browser is stuck or something went wrong.

Not sure what the bug is here.  Are you requesting this for the default viewer as well?

The reason that the Silverlight viewer has a percentage loading screen is because when you visit the page with the Silverlight viewer in it, it downloads the latest version of the viewer, just like any other part of the page.

By contrast, the deluxe/default Photosynth viewer does not need a loading screen because it has been 100% downloaded and is sitting in your internet browser's plugin folder. It loads almost instantly.

As for a "synth file tak[ing] over 3 or 4 minutes to download and currently... display[ing] only blackness", the viewer only downloads the data for the current view. That includes the pixels neccesary for the photo currently in focus at the current resolution on screen plus low resolution versions of the surrounding photos. After you move to the next photo, all previously downloaded data is dumped as the information for the new view is downloaded. This is so that you do not wind up with a mountain of data in your temp folder.

In short, there is no time when the entire synth is downloaded to your machine so if you are waiting three or four minutes with nothing but a black screen there is something wrong.

Hi Marvin, Nathanael, thank you for the explanations. Could you try this synth and see how long you see the initial blackness?

For me, the "first" time in the default viewer (not Silverlight) takes 3 to 4 minutes in Firefox. Subsequent times are less. So I'd like to if there's something wrong with my setup, or, it would be nice for the default viewer to show some kind of progress meter during the 4 minutes of blackness. :)  Thanks.

??? maybe 10 seconds with IE7          (photosynth viewer from this link)
PGRic (Over 1 year ago)
yes, same here 10secs on IE7 on a 20mb line

Pierrot, what is your download speed? PGRic, my download speed is less than 1.5Mb/s (around 1,315kb/s == 1.284Mb/s). So 20Mb/s == 15* 1.28Mb/s. So 15 x 10 secs == 150 secs == 2.5 minutes. If my low download speed is the reason for the few minutes of blackness, it would be nice to have a progress meter. Thanks.

I got 11 seconds from the time the viewer appeared on the page until the first image was completely in focus at the initial size on my screen (4:3 display at 1600x1200 | viewer not maximised | Firefox 3.1 Beta 3). This was while uploading the end of my 'Monumental' synth and while another laptop on my home network was pulling heavy traffic with a torrent program.
