[djembe]

ffmpeg fails to convert audio stream while converting to mov.
options i am using are:
-y -i -b 7600k -r 29.97 -ab 128k -ar 48000 -ac 2

why this fails ?

error log is:

My guess would be that either your input file is damaged/non-standard, or the particular version ffmpeg you have has trouble handling it properly. So the question is what other decoders or players do with this input?

If the evidence seems to point at ffmpeg, what I normally do is see if a more recent version no longer has that bug, or use something like Avidemux to do an intermediate re-encode (of the audio in this case) hoping that ffmpeg can handle that.
