ASLA 입출력 - mplayer / ffmpeg

mplayer에서는 -ao alsa:device=hw:0.0 식으로 음악을 바로 재생을 할 수 있는데..
ffmpeg은 입력을 받아서 저장은 되도.. 플레이는 안되나.. 보다 싶긴하다.

$ man ffmpeg    Video and Audio grabbing        If you specify the input format and device then ffmpeg can grab video and audio directly.                ffmpeg -f oss -i /dev/dsp -f video4linux2 -i /dev/video0 /tmp/out.mpg        Or with an ALSA audio source (mono input, card id 1) instead of OSS:                ffmpeg -f alsa -ac 1 -i hw:1 -f video4linux2 -i /dev/video0 /tmp/out.mpg        Note that you must activate the right video source and channel before launching ffmpeg with any TV viewer        such as <http://linux.bytesex.org/xawtv/> by Gerd Knorr. You also have to set the audio recording levels        correctly with a standard mixer.

$ mam mplayer AUDIO OUTPUT DRIVERS (MPLAYER ONLY)        Audio output drivers are interfaces to different audio output facilities.  The syntax is:        -ao <driver1[:suboption1[=value]:...],driver2,...[,]>               Specify a priority list of audio output drivers to be used.        If  the  list has a trailing ',' MPlayer will fall back on drivers not contained in the list.  Suboptions        are optional and can mostly be omitted.        NOTE: See -ao help for a list of compiled-in audio output drivers.        EXAMPLE:                  -ao alsa,oss,                       Try the ALSA driver, then the OSS driver, then others.                  -ao alsa:noblock:device=hw=0.3                       Sets noblock-mode and the device-name as first card, fourth device.
