[FFmpeg-user] Audio transcoding

[Diljit Singh]

I tried it , but doesn't seem to be working.

Then I tried following command
ffmpeg -i SDR.wav -acodec pcm_u16be -ar 8000 -ac 1 -y SDR_final.wav

When I tried to test output file in vlc player it still shows 8 bit sample
width.

Please suggest.

Regards,
Diljit singh
