#6874 open defect

"Invalid image height" decoding seemingly valid animated gif

Reported by: eefp Owned by:
Priority: normal Component: avcodec
Version: git-master Keywords: gif
Cc: Blocked By:
Blocking: Reproduced by developer: yes
Analyzed by developer: no

Description

Summary of the bug:
After successfully converting numerous animated gifs to mp4, we ran into one that ffmpeg chokes on. It gives the error for the sample linked below:

[gif @ 0xac23860] Invalid image height.
Error while decoding stream #0:0: Invalid data found when processing input

The gif in question animates properly in the web browser and can be decoded without warning by other gif tools

How to reproduce:

ffmpeg -i ani_gif_invalid_image_height.gif -f mp4 xyz.mp4
