I find it very distracting to have half of the screen consumed by version
of ffmpeg, build options and libraries options.

There is no need for any (ANY, not even the first line) of these by default, because there are:

ffprobe -version

that shows the same information  (on stdout).

And more comprehensive / machine parsable commands:

ffprobe -show_program_version
ffprobe -show_library_versions
ffprobe -show_versions  (both two above combined)


Having option that restores some build info to be printed and continues
execution could be useful for some tho. But it should not be enabled by
default, and should output all these build info details to stdout.

Best regards,
Witold Baryluk


PS. Notice that the ffprobe output data to stderr, instead to stdout,
which is also weird, and other bug.

I can understand that you're not happy with the current situation.
Unless this is fixed upstream, we won't change that in the Debian
package. Closing as wontfix.
