[Ffmpeg-devel] FLV conversion audio problem

[Vishwajeet Wadhwa]

Following is bug report format:
1. We are trying to transcode audio(wav,mp3,wma) and
video(avi,mpg,mov,wmv) formats to flv format.

2. FFMPEG transcoded all video formats into flv format but the resulted
flv file, we get is video only(without audio).We are not able to
transcode any of the audio formats into flv format.

3. The following command format is used for all video and audio formats:
        i)  ffmpeg -i xyz.mpg abc.flv
        ii) ffmpeg -i xyz.mpg -b -360 -r 25 -s 640x480 -hq -deinterlace
-ab 64 -ar 44100 -ac 1 abc.flv

4.
   i) Output for the command "ffmpeg -i xyz.mpg abc.flv"

          Input #0, mpeg, from 'Nasa.mpg':

How can we get audio support in flv converted files.Any kind of help
will be appreciated
