How to set the probesize in ffmpeg

Hi all,

I'm transcoding some stream with ffmpeg. ffmpeg got stuck during probing (I guess) before transcoding unless I set a small probesize. ffplay also cannot play this stream unless I set a small probesize.

When I used avconv and avplay of libav, I did not encounter this problem.

Stream info:
    Stream #0.0(chi): Audio: wmapro, 32000 Hz, stereo, fltp, 32 kb/s
    Stream #0.1(chi): Video: vc1 (Advanced), yuv420p, 320x240 [PAR 1:1 DAR 4:3], 150 kb/s, 4 fps, 1k tbn, 30 tbc
    Stream #0.2(chi): Data: [0][0][0][0] / 0x0000, 4 kb/s

I think this is a problem of probing. I'm wondering if this is a difference of default AVOptions between ffmpeg and libav.

Looking forward for your reply and thanks in advance
