Fixes #1871. Fix number of frames in the pulldown check. 2020-08-03T08:00:49Z Carl Hetherington cth@carlh.net 2020-08-03T07:51:27Z urn:sha1:a600c8e557583dd730960297aa436169654fc607 Backported-from-commit: 5f1fdbafc6eef37523250e0b8542a8939a038823 Backported-from-branch: v2.15.x Fix incorrect string find logic. 2020-08-03T08:00:13Z Carl Hetherington cth@carlh.net 2020-08-03T07:51:12Z urn:sha1:75820f6fe6d1d2de7546694c6c875c24b40478bf Backported-from-commit: d461077cf4f2c1470d2d0d6dbc4f5708411bec65 Backported-from-branch: v2.15.x Detect soft 2:3 pulldown (telecine) files and decode them at 23.976. 2020-08-02T20:30:18Z Carl Hetherington cth@carlh.net 2020-08-02T20:24:05Z urn:sha1:b58ea0495d72d654161958e515dc6c5ba9992b80 DVD rips from NTSC DVDs are sometimes (always?) encoded using soft 2:3 pulldown. The video frames are actually 23.976 but FFmpeg detects them as 29.97. With the current approach of the video decoder ignoring most PTSs and assuming a constant frame rate it is vital that the file contains the number of frames per second that the detected frame rate predicts. This fixes large sync errors with NTSC DVD rips (#1790). Cherry-picked from af680761cf7c3e97660e8e55c68f42e90b026bf9 in v2.15.x.

I hope this isn't a bad idea; this commit should be reverted if there any hints of misread video frame rates. Don't throw an exception if we can't find bits_per_pixel, as it's not the end of the world. 2018-01-12T00:27:16Z Carl Hetherington cth@carlh.net 2018-01-12T00:27:16Z urn:sha1:81a93ab80d04a0d01783266139cac982eb342421
