[FFmpeg-user] Problem with -vf crop with current git

[Steve Kenton]

It looks like -vf crop gets ignored for the raw video input stream file 
if followed on the command line by a raw audio stream input file but 
switching the order of the two inputs on the command line make it work. 
Am I doing something stupid or is this a bug? Test script and output below.

Thanks - Steve

#!/bin/bash
# zot script to demonstrate -vf problem with ffmpeg 1.0

# This gets encoded to mpeg at 720x486 - the crop is ignored
ffmpeg -threads auto -f rawvideo -vcodec rawvideo -video_size 720x486 
-pixel_format uyvy422 -framerate 30000/1001 -i clip1.raw -vf 
crop=320:240 -f s16le -acodec pcm_s16le -sample_rate 28000 -channels 2 
-i clip1.aud -y xxx1.mpg

# This gets encoded to mpeg at 320x240 - the crop is processed
ffmpeg -threads auto -f s16le -acodec pcm_s16le -sample_rate 28000 
-channels 2 -i clip1.aud -f rawvideo -vcodec rawvideo -video_size 
720x486 -pixel_format uyvy422 -framerate 30000/1001 -i clip1.raw -vf 
crop=320:240 -y xxx2.mpg
