 How can I limit log output to specific values? I want

 "ffmpeg.exe -i input.mp4 -f mp3 -acodec mp3 -vn output.mp3"

 command's log to contain only

 "size= 161kB time=00:00:10.29 bitrate= 128.3kbits/s

 size= 359kB time=00:00:22.95 bitrate= 128.1kbits/s

 size= 532kB time=00:00:34.03 bitrate= 128.1kbits/s

 size= 704kB time=00:00:45.00 bitrate= 128.1kbits/s"

 How can I succeed this?
