[FFmpeg-cvslog] ffmpeg: add -(no)stdin option.

[Nicolas George]

ffmpeg | branch: master | Nicolas George <nicolas.george at normalesup.org> | Wed Jul 11 21:10:17 2012 +0200| [0fe8acf2d69bf4bce620128e48b62a957421a106] | committer: Nicolas George

ffmpeg: add -(no)stdin option.

Allows to disable interaction from standard input.
Useful, for example, if ffmpeg is in the background process group.
Roughly the same result can be achieved with "ffmpeg ... < /dev/null"
but it requires a shell.
