5 /dev/null truncates to /dev/nu on load of PNG or JPG - ID: 2892554
Last Update: Settings changed ( gfinch )

Trying to lad the JPG or PNG frame anew leads to MsgBox claiming to look at
the terminal. Here is what I see out there:

Maybe you are missing a library in mplayer (or it is not a valid media
file) ?

I think this is because of error in a shell command, probably it gets
truncated.
System is: freebsd-7.1 as of January, 2009 and lives port of that date.

Patch did not make it work.
But I updated to 1.0.5 from the ports (freshports.org-cvsweb-tarball) and
it works without patch.
Thank you I should report 2 more troubles if no objections.

Another user just emailed me a png which would not open, the problem was
found to be with mplayer which was incorrectly labelling the image file as
audio.

You can try the following patch and see if it solves this problem. You
need to change 1 line in /usr/bin/smogrify, around line 3529:

change:
if (($hsize*$vsize==0||$count eq "")&&!($type eq "Audio")) {

to:
if ($hsize*$vsize==0||$count eq "") {

please let me know if it fixes the problem for you so I can close this
bug.

version is: lives-0.9.8.10_2
ImageMagick-6.4.8.3
Those can be easily seen at, for example:
http://www.freshports.org/multimedia/lives/
for that moment.
I can update to a newest version, should it be fine to update the lives
only?

There is something very strange going on here, because the file should be
recognised as a jpeg and should never even be passed to mplayer.

Do you have imageMagick installed ?

Also January 2009 would be a very old version of LiVES. What is the
version number (from Help/About) ?

As a workaround, I made a symlink /dev/nu to /dev/null and it works. Should
be interesting to get rid of this though, thanks.
