Actually, your hint regarding "ffmpeg -codecs" is most important.
Mine reports this:
> /usr/new/tools/video/ffmpeg-current/bin/ffmpeg -codecs 2>/dev/null | grep aac
 DEA.L. aac                  AAC (Advanced Audio Coding) (encoders: aac libfdk_aac )
 D.A.L. aac_latm             AAC LATM (Advanced Audio Coding LATM syntax)

So Ritesh would have to use "-codec:a libfdk_aac".

Furthermore, Ritesh wrote:

Ritesh, that is somewhat ambiguous. You shouldn't be stating both
"-acodec aac" and "-c:a libfdk-aacenc". Stick to just one. :-)
