Description
I am trying to use the bmovl filter to display video annotations alongside a video of mine, and the filter displays the bitmap data in a wrong way, resulting in a weird tilted shape.
To easily reproduce this: I attach a small tarball, where I "play" a single image in a loop (-loop 0) and feed bmovl with random data (from /dev/urandom). You'd expect to see a rectangle of noise - instead, you see a tilted shape.
All you need to do to see the bug is untar the tarball, and run "./bug.sh". I also attach a screenshot of the "tilted" window.
