Hello Vivek,

If ffmpeg is having trouble working with your original source files,
or if you need to "explode" a PDF into images beforehand, you might
want to try the Convert utility from ImageMagick. Off the top of my
head, I can suggest throwing your problematic images into it and
converting them to raw bitmaps (.bmp files), and then feed those files
into ffmpeg.

Regards,
Andrew

No, FFmpeg does not support anything about PDF. The simplest tool for that
kind of task would probably be pdftoppm from poppler.

hey Nicolas/Cley,

Thanks for correction. Image formats were getting destroyed due to some
optimisations/compressions done on them via a 3rd party service.
Would you know if ffmpeg provides any utility to convert a pdf into images
which could then be fed to create slideshow video?

​I'm still learning about ffmpeg, but what I know is that concat expect all
the files to have roughly the same layout and codecs. As it is, it is
decoding all your files using what's found in the first file (a jpeg), so
all your files must be jpegs.
The same thing happen if you use concat with multiple files with clashing
audio settings (different rates, different channel layouts, etc): the
output is garbled (or just fail to process).

Also, although it doesn't matter here, you might want to avoid naming your
files ".png" if they really are jpegs...

Below is the output. I see the below 2 files which errors out are PNG

Can you show the output of the file command on all your input files?
Something like:

cd /Users/Vivek/Desktop/MY_THING/572702262753189307/1446116853251Introtomgt.pptx
file out_*

​Entire output is always a good idea.
Also, I'm not sure, but I don't think 'duration' is used that way in a
concat file. Complete output might confirm this.
