#7964: Predictively skip frames to smooth out timestretch
-------------------------------------+--------------------------------------
Reporter: jppoet@… | Owner: markk
Type: enhancement | Status: accepted
Priority: minor | Milestone: 0.24
Component: MythTV - Video Playback | Version: head
Severity: medium | Mlocked: 0

Comment(by markspieth):
patch 4 has the previous improvements plus:
1. better unpause and start playing response. This almost eliminates the
frame doubling required at start of play or after seek/unpause. Reduces
the zero write latency when audio is paused, and discards any audio
packets which come before the first video packet.
2. faster avsync convergence. convergence is now adjusted by a frame
interval period.
item 1 can be split from the patch if desired. audiooutputbase.cpp and
avformatdecoder.cpp,h
the vsync patch can also be split as it is also independent on the other
changes in NVP.
