+Subject: [PATCH] fftools/ffmpeg: Restore DTS correction for VP9 copies
+
+Fixes ticket 9086.
+
+Since early 2021, some of YouTube's VP9 encodes have non-monotonous DTS.
+This makes ffmpeg fatally fail when trying to copy or encode the V9 video.
+
+ffmpeg already includes functionality to correct this, however it was
+disabled without explanation for VP9 stream copies in
+2e6636aa87303d37b112e79f093ca39500f92364
+
+This patch restores the DTS correction logic, and allows ffmpeg to correctly
+encode (invalid) videos produced by youtube.com. I have verified that frames
+are NOT being cut (so it does not re-introduce 4313).
