[transcode-users] transcode failing to code .png files

[Dean S. Messing]

Hello.  

I'm getting the following error when I try to transcode a sequence of
70 .png files (see 2nd line below and 4th line from end of output):

================

The file "im_in_list" contains the names of the 70 .png files:

./im000.png
./im001.png

and so on.

The files were created by ImageMagick and, in fact,
`identfy im000.png' returns:

im000.png PNG 1024x540 1024x540+0+0 DirectClass 8-bit 805.715kb 


The system is system is A Fedora Core system with a slightly later
version (6.3.4) of ImageMagick than is supplied by the distribution.
Of course, I rebuilt transcode for this version.

The really strange thing is than on an Fedora Core 6 laptop with
the _exact_ same version of ImageMagick and transcode, I get the initial
error "[fileinfo.c:118] file read error: Wrong medium type" but then
transcode goes ahead and codes all the frames.

I'm stumped.
