Please accept my apology for putting a large size msg. I appreciate all the
help received.
I have another example with similar behavior. The exact commands used are
below. The detailed output is attached in this email.
*command 1*: ffmpeg -i call.wav -af
"volume=enable='between(t,0,1)':volume=0" output.wav
*behaviour: *executed within a second, input file size 2.1 mb, output file
size 176 mb
*command 2*: ffmpeg -i call.wav -af
"volume=enable='between(t,0,1)':volume=0" output.mp3
*behaviour: *executed time approx 40 seconds, input file size 2.1 mb,
output file size 15 mb
Thanks for the support.
Regards,
Shubham
