Revisit deinterlacing of mixed progressive/interlaced content

Reported by: Mark Kendall Owned by: Mark Kendall
Priority: minor Milestone: 32.0
Component: MythTV - Video Playback Version: Master Head
Severity: medium Keywords: deinterlacing, interlaced, progressive
Cc: Ticket locked: no

Description

mythplayer generally locks the scan type to interlaced when interlaced frames are seen - and hence will not revert if the stream changes to progressive.

This was historically designed to stop frequent switches - which interferes with playback when deinterlacers are continually enabled/disabled and/or created/deleted.

Frequent switches are often seen with e.g. telecined material.

We should however detect when the stream has 'properly' switched.

This may be as simple as unlocking the scan type on GOP boundaries.
