Comment (by fritsch):

 Issue exactly:

 ffmpeg before this change: Output would be a 64 KB image
 ffmpeg after this change: something (a 4kb image is output) and the real
 image won't as decoding it results in "Invalid data found when processing
 input"

 Which ffmpeg command would you suggest to extract the full image? And how
 would you workaround that in code? (e.g. use image2 demuxer to parse it
 away?)

 And how do you explain the changed behaviour between image2pipe and image2
 - one is creating an error, the other one is outputting the 64 kb frame?
