[FFmpeg-devel] [PATCH 1/2] avfilter/vf_tpad: fix check for drawing initialization

The check if drawing needs to be initialized and supported formats
should be drawable ones was flawed, as pad_stop/pad_start is only
populated from stop_duration/start_duration after these checks.
To fix that, check the _duration variants as well and for better
readability and maintainability break the check out into its own
helper.
Fixes a regression from 86b252ea9dee18006910e30646ad1067f2d1323f
Fix #10621
