Flash Video (FLV) to wav or mp3
It´s can be in two easy steps. First extract the audio track using mplayer, then encode the wav-file to an mp3 using lame. The -novideo option makes this operation faster.
mplayer -ao pcm:file=sound.wav -novideo flashvideo.flv lame sound.wav sound.mp3
This can be used for example to download music from Youtube. Possibly there is a better way with mencoder?
Video to PNG files
Writing a PNG file for each frame in the Video file. PNG files will be written to the current directory.
mplayer -nosound -benchmark -vo png:z=0 /path/to/video.avi
Output files are named 00000001.png, 00000002.png, 00000003.png, ...
It might be useful to crop and/or scale the video before writing PNGs:
mplayer -nosound -benchmark /path/to/video.avi -vf crop=100:10:80:80,scale=50:50 -vo png:z=0
This takes a 80x80px area, starting from (x,y)=(100,10), scales it to 50x50px and writes a PNG file for each frame.
