freepv isn't able to download a file to play

[Gerhard Gaußling]

Hello,

It seems, that the freepv stand alone applications freepv-glx and
freepv-glut aren't able to download a qtvr file from the net, and
therefor I'm not able to load panoramas with the
MediaPlayerConnectivity Extensions
(https://addons.mozilla.org/de/firefox/addon/446) for firefox, and I
doubt, that it is possible to load them by plugger
(http://fredrik.hubbe.net/plugger.html) into the standalone freepv
programs. lease, have also a look here (sorry, german):
http://www.firefox-browser.de/forum/viewtopic.php?p=394623#394623

Here ist the output of the two programs:

$
freepv-glx "http://www.bruno.postle.net/panorama/abu-dhabi/stuart-in-street-qtvr.mov"
XF86VidModeExtension-Version 2.2
Got Doublebuffered Visual!
glX-Version 1.3
Depth 24
Congrats, you have Direct Rendering!

You could write a wrapper script that uses curl or wget to download
the file to a temporary filename, calls freepv-glx to view it and
then deletes the file afterward.

Downloading a file is a complicated task, you have to deal with
http, https, ftp, different port numbers, redirects etc... I
haven't checked but I'm sure the plugin uses mozilla to do this bit.

A segfault is a bug that should be fixed anyway.

but I think that is not a bug, because it's a result of "failed: No such
file or directory". Maybe, instead of a segmentation fault there should
be a message like: "Not able to download the file, please use a wrapper
script. See details in man freepv "

Thank you, I'll try to write such a wrapper for that purpose.
Here it is:

#!/bin/sh
cd /tmp
wget $1
PATHNAME=$1
freepv-glx ${PATHNAME##*/}
rm ${PATHNAME##*/}
