[Paul B Mahol]

ffmpeg | branch: master | Paul B Mahol <onemda at gmail.com> | Tue Sep 28 00:34:40 2021 +0200| [71f2a9a2e53fa0cd9707bc35ce4d56459aad61b7] | committer: Paul B Mahol

avfilter/vf_remap: remove timeline support

It is not supported, as it is possible to change frame video width
and height and that can lead to undefined output.
