 Hi, All.
   When I convert a mp4 file to capture a jpg file, it can not convert
 successfuly(The output file was not generated).
 Execute command: ffmpeg_g  -ss 20 -t 0.001 -vframes 1 -i input.mp4 -y  -f
 image2 -s 350x240  outfile.jpg
 OS: Win7+MinGW32
 The log file information: (It looks like lack of parameters, but I have
 supported parameters: "ss, t, vframes")

 2012/01/30-10:25: Output file is empty, nothing was encoded (check -ss /
 -t / -frames parameters if used)

 But When I execute the same file in ffmpeg v0.9 (the same OS), it is ok.
 Could you help me please? Thank you in advance.
