This bug can be seen very clearly with e.g. mplayer -vo aa -monitoraspect 3
|
|
in which case a big part of the picture is missing or there is even completely
|
|
black output.
|
|
|
|
The reason for this is, when drawing only a part of the picture via aarender()
|
|
the first X coordinate is used for the loop count, but it is not applied to the
|
|
destination and source image index, thus instead of (re)drawing the middle part
|
|
of the image, it draws always the left part.
|
|
|
|
Actual Results:
|
|
only the left part of the image is draw (depending on the video, only the left
|
|
black bar might be draw, so you will see nothing at all - if so use a slightly
|
|
smaller value for -monitoraspect).
|
|
|
|
Expected Results:
|
|
All of the image should be drawn, and -monitoraspect should only squeeze the
|
|
image, not cause part of it to miss.
