I have to convert a number of video files to audio format but its very painful and time consuming to convert them one by one. Is there a way to convert them in a batch with VLC player?

If you want to use ffmpeg, you can use the following to extract the audio parts of all WMV files in the current folder to uncompressed WAV (PCM audio):
for f in *.wmv; do ffmpeg -i "$f" "${f%.wmv}.wav"; done
Or MP3 – see the MP3 encoding guide for more info:
for f in *.wmv; do ffmpeg -i "$f" -c:a libmp3lame -q:a 2 "${f%.wmv}.mp3"; done
These are loops for Linux shells like Bash. For Windows, you'd do something like the following:
for %%A IN (*.wmv) DO ffmpeg -i "%%A" "%%A.wav"
It depends on your OS:
- If you have Windows, it is straightforward to do in the UI:
VLC->Media->Open multiple files.
- If you are a Mac or a Linux user, there are bash scripts (see here).
- The above link also has scripts for windows users, if you prefer.
Apart from VLC, HandBrake is a very powerful platform independent (though it was developed for Mac) conversion app that easily allows batch conversion.
