Ticket #2916: ticket_2916_attempt2.diff

File ticket_2916_attempt2.diff, 1.6 KB (added by skamithi, 17 years ago)

modify auto deinterlacing detection code. make it more sensitive for dvds so wthat progressive frames seen right after a series of interlaced frames is not deinterlaced. i can reproduce consistently with bobdeint filter and lord of the rings II. the FBI warning frame is a progressive frame and experiences the problem. workaround is still to disable bobdeint.
