ffmpeg + crop + pad broken?

Atm. I'm using something like:
Code:
ffmpeg.exe -v 0 -r 23.976 -i "D:\Test.m2ts" -threads 4 -v 0 -croptop 130 -cropbottom 132 -cropleft 0 -cropright 0 -padtop 130 -padbottom 132 -vsync 0 -an -r 23.976 -pix_fmt yuv420p -f rawvideo - | x264 --crf 20 --fps 23.976 --output "test.264" - 1920x1080
for encoding

using a ffmpeg Version from:
http://sourceforge.net/projects/mplayer-win32/files/
or
http://ffmpeg.arrozcru.org/autobuilds/

Problem is, newest versions just stop and post:
"Please use vf=pad"
(older once work fine)

Since I couldn't find anything over at http://www.ffmpeg.org/ffmpeg-doc.html why this is happening I thought I might ask here if someone knows what's going wrong.

Is there a new option for padding, or is there a but in newer ffmpeg versions?

(replace "-vfilters" with "-vf", they need to update the docs)

using latest from http://ffmpeg.arrozcru.org/autobuilds/ with:
Code:
ffmpeg -v 0 -r 25.000 -i "D:\sx264\test.mp4" -threads 4 -v 0 -vfilters "crop=640:350:0:2, scale=720:394, pad=720:576:90" -vsync 0 -an -r 25 -pix_fmt yuv420p -f rawvideo - | x264 --crf 20 --fps 23.976 --output "test.264" - 1920x1080
I get:

Looks like you have misunderstood what Pete meant: do NOT use -vfilters but use -vf instead.

Apparently I dont':
Code:
ffmpeg -v 0 -r 23.976 -i "D:\testclips\IronMan2_avc_aac.mov" -threads 4 -v 0 -vf "crop=0:4:1280:540,scale=1280:656,pad=1280:720:32:0" -vsync 0 -an -r 23.976 -pix_fmt yuv420p -f rawvideo - | x264 --pass 2 --bitrate 1500 --level 4.1 --direct auto --qpmin 1 --partitions i4x4,p8x8,b8x8 --subme 5 --trellis 0 --no-fast-pskip --weightp 1 --aq-mode 0 --vbv-maxrate 62500 --vbv-bufsize 78125 --sar 40:33 --stats "D:\test_19_47_30_003_01.stats" --fps 23.976 --output "D:\Encoding Temp\test_19_47_30_003_02.264" - 1280x720
gives me:
Quote:
[crop @ 013e6f60]x:0 y:4 w:1280 h:540
[scale @ 013e70f0]w:1280 h:540 fmt:yuv420p -> w:1280 h:656 fmt:yuv420p flags:2
[pad @ 013e6f20]w:1280 h:720 x:32 y:0 color:0x10808000[yuva]
[pad @ 013e6f20]Input area 32:0:1312:656 not within the padded area 0:0:1280:720 or zero-sized
but the syntax seems to be right, or not?
-vf "crop=0:4:1280:540,scale=1280:656,pad=1280:720:32:0"
should crop to 1280x540, then resize the result to 1280:656 and then pad to 1280:720.

You don't add any padding in the X-direction, so you can't use any X-offset. Did you maybe mean pad=1280:720:0:32 ?
