Hello,

I've been using VLC for a while, yesterday I updated vlc by apt (debian jessie).
The problem is, png files created by latest version of vlc isn't valid.
It can be loaded by many programs but some programs return an error.
I've tried recompiling vlc, even with static library(contrib), but it didn't work.

jpg, tiff files work fine.

This image for example:

Code: Select all

$ gm identify -verbose vlcsnap-00254.png 
gm identify: Too many IDAT's found (vlcsnap-00254.png).
gm identify: Request did not return an image.

Code: Select all

$ pngcrush -n -v vlcsnap-00254.png 

...

While reading vlcsnap-00254.png:
  pngcrush caught libpng error:
   Too many IDAT's found

Should be fixed now, thanks for reporting.

Should be fixed now, thanks for reporting.

All programs can read it now, but the snapshot is completely broken.

This is what it's supposed to be:

ah sorry about that, this didn't happen for any of the videos i tested, but I was able to reproduce it when i took a snapshot of a 1500x1200 image. Should actually be fixed now, thanks. What resolution is your source material?

496x322 and 1344x610, both video had same problem.
I didn't test 1080p or 720p videos, though.

It works perfectly now. 1080p, 720p, 496x322 and 1344x610, everything works. Thanks!
