Created page with "== 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''..."

New page

== 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.
<nowiki>mplayer -ao pcm:file=sound.wav -novideo flashvideo.flv
lame sound.wav sound.mp3</nowiki>
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.
<nowiki>mplayer -nosound -benchmark -vo png:z=0 /path/to/video.avi</nowiki>
Output files are named ''00000001.png, 00000002.png, 00000003.png, ...''

It might be useful to crop and/or scale the video before writing PNGs:
<nowiki>mplayer -nosound -benchmark /path/to/video.avi -vf crop=100:10:80:80,scale=50:50 -vo png:z=0</nowiki>
This takes a 80x80px area, starting from (x,y)=(100,10), scales it to 50x50px and writes a PNG file for each frame.
