 Summary of the bug:
 I'm using FFmpeg to create a web encoding client. But the problem is
 there's no docs about the data produced by -vstats_file option.
 Example:
 {{{
 out=  0 st=  0 frame=   718 q= 35.0 f_size=    894 s_size=     2877kB
 time= 29.793 br=   171.6kbits/s avg_br=   791.1kbits/s type= B out=  0 st=
 0 frame=   719 q= -1.0 f_size=    824 s_size=     2878kB time= 29.834 br=
 158.2kbits/s avg_br=   790.2kbits/s type= B
 out=  0 st=  0 frame=   720 q= -1.0 f_size=    980 s_size=     2879kB
 time= 29.876 br=   188.2kbits/s avg_br=   789.4kbits/s type= B
 }}}
 In documentation there's no mention about which key means what. For
 example what does out= mean? st= ? also what are type=B/I/P ?
 Please explain.
 Also how am I supposed to know that the encoding process is completed?
 How to reproduce:
 {{{
 $ ffmpeg -i input ... -vstats_file file.txt output
 ffmpeg version
  4+
 built on Debian 10
 }}}
