ffmpeg gets IO errors about 3/4 way through gource PPM file about gource HOT 8 OPEN

Hi,

If you can figure out what is wrong with the ppm (possibly not that easy to do) 
we'd know if its a problem with avconv or gource or something else.

It could be the disk partition filled up while making the recording causing the 
ppm file to be truncated.

Disk has plenty of room. I regenerated the file several times, and it pays all 
the way to the end in gource, but when I try to convert it to a movie file, it 
dies in the same place every time.

If you have a suggestion for debugging, I'm happy to try.

Maybe try this:

Install the graphicsmagick ubuntu package and then run:

gm identify gource.ppm

It will list and describe all the ppms (assuming it can handle the huge number 
of ppms in this case) in gource.ppm and will hopefully identify which ppm is at 
fault if that's the problem.

$ gm identify ogource.ppm 
gm identify: Unexpected end-of-file (gource.ppm).
gm identify: Request did not return an image.

Oh! I found a work around - if I pipe the output of gource directly into 
avconv, it works fine... it's only if I output a PPM file in the middle that it 
fails.

Good to know that method works. Makes me wonder where the issue is.

Yeah... me too. :( But from the output of `gm` it looks like a stray EOF 
character?

It might be the file is truncated for some reason, but it wont be an EOF as a 
file cant actually contain those.
