 Summary of the bug: ffmpeg even with -loglevel debug provides no data
 about input colorspace that will be used later by encoder.
 How to reproduce:
 {{{
 % ffmpeg -loglevel 5 -i bd.mkv
 ffmpeg version 4.1
 built on Antergos Linux
 Using the command -vf colorspace=all=bt601-6-625:iall=bt601-6-625 I found
 out that ffmpeg treats input video as BT.601 (I compared first screenshot
 made with -frames:v 1 default.png with screenshot made using this filter).
 Why not BT.709? Where does ffmpeg get the information?
 }}}

 Patches should be submitted to the ffmpeg-devel mailing list and not this
 bug tracker.
