I need to stuck logs from ffmpeg.

So I command like below.

ffmpeg -f rtsp -rtsp_transport tcp -ss 600 -i rtsp://aaa.bbb -vframes 1 out.jpg>aaa_log.list

I already confirm that this command makes fine outputs, except ">aaa_log.list" part.

It makes file with the name "aaa_log.list", but does not write anything.

My OS is Ubuntu 12.04 64bit and ffmpeg version is 1.2.0.

Thnaks.
