Gnome mplayer, mplayer, And the firefox plug-in gecko-player of mplayer (used to replace the function of windows media player to play the integrated audio player on the internet explorer webpage. However, codec must be fully installed, especially win32codec and ffmpeg. mp3 decoder such as fluendo or replacement, lame, gstreamer-uugly, gstreamer-uugly-multiverse, gstreamer-good and bad, of course these are installed. Some systems are called w32codec)

This command is only available in command line mode. Gnome is used by Ubuntu by default, and kde has never been tried. Start gnome-terminal

Run the cd command to enter the folder where the flv file is located.
. For example, my flv file is 360000028.flv.
Then the command line,
Sudo mplayer-dumpaudio 360000028.flv-dumpfile 360000028133
A prompt is displayed on the command line interface. My mplayer is version 1.0 rc4.
After that, the FLV folder will generate the file named 360000028133. Play the video.

However, there is a problem. Although the extracted mp3 files are quick, the estimation of the playback progress will be distorted.
This problem also occurs in gadgets with similar functions in windows.

However, if you do not drag the progress bar to play the video, it is not a problem. Normal playback is okay. Dragging the progress bar of the Media Player may cause the player to terminate abnormally.
