[MPlayer-dev-eng] Cropdetect Aspect Ratio display & True Speed Patches

Attached are two patches:

a) crop.diff
adds another field to the output of the cropdetect filter containing the
true aspect ratio of a video:

[CROP] Crop area: X: 0..719 Y: 0..479 R:1.78:1 (-vf crop=720:480:0:0).
                                      ^^^^^^^^
[CROP] Crop area: X: 0..719 Y: 73..510 R:2.34:1 (-vf crop=720:432:0:76).
                                       ^^^^^^^^
[CROP] Crop area: X: 0..719 Y: 74..501 R:2.39:1 (-vf crop=720:416:0:80).
                                       ^^^^^^^^

working for all situations I came across to date.


b) speed.diff
adds a command line parameter -speed24, which in case of PAL material
(25fps) switches to a playback speed of 24fps downpitching the audio
also as intended.

If no downpitching is necessary (very few PAL DVDs have pitch correction
applied) -af scaletempo would be needed though, otherwise the voices
would be half a tone too low.
