Hi Andy,<br>
<br>
Thanks for testing the patches.<br>
<br>
Please send me the videos and ratios with which there is corruption.<br>

This has no aspect encoded and displayed fullscreen on a 1920x1080<br>
monitor shows vertical line artifacts over the first 2/3 of the image.<br>
<br>
When I say lines they are not lines as such just that the distortion<br>
on the pendulum shows as it passes over imaginary lines at fixed<br>
points on the screen.<br>
<br>
with mplayer -aspect 4/3 or 16/9 it doesn't.<br></blockquote><div><br></div><div>I tested the videos and found out that the distortion is because of the amount</div><div>of calculation done in the fragment shader. I tested the video with vl_median_filter</div><div>and it showed no distortion however, with vl_matrix_filter( which requires more </div><div>calculations than vl_median_filter) it showed the same distortion. I'll try to make it </div><div>more efficient.

That one is 720x576, with a 704x576 like -<br>

4/3 still has the vertical "line" artifacts - 16/9 doesn't.<br>
<br>
On other vids there is a hint of horizontal distortion, I'd need time<br>
to cut the one I saw that on - it was subtle on a 1440x1080 16/9 long vid.<br>
