The patch checks if the file is smaller than the smallest
|
|
video frame size, and if it's smaller, there can't be a
|
|
valid video file in it, hence, the file is truncated
|
|
and there is nothing to play in it.
|
|
|
|
See https://bugzilla.novell.com/show_bug.cgi?id=157631
|
|
for further information.
