#142: [FFmpeg/filters/overlay] PNG over a movie doesn't look write in 0.7

----------------------+----------------------
 I'm trying to overlay a static PNG file over a movie with FFmpeg 0.7-rc1
 but the PNG file is not rendered correctly.
 The same command line produces the expected result with FFmpeg 0.6.9-rc0.

 ffmpeg -v 9 -loglevel 99 -i chuck_intro_lq.webm -acodec copy -vf
 "movie=vert_100x100x32.png [wm];[in][wm] overlay=W-w-10:H-h-10 [out]"
 chuck_intro_lq_overlay_ffmpeg-0.7-rc1.webm

 Please note that I've also tried with libxvid codec and an avi container;
 the result is the same (not correctly rendered picture).

 The picture is a plain opaque green square saved in a 32bits PNG (with
 alpha channel).


 It may be that I'm doing something wrong, but why was it working in
 0.6.9-rc0.
