flv file plays badly with (default) -correct-pts

[cehoyos]

(This issue is not related to SBR.)

flv_h264_aac_sbr_slow_playback_or_vid_freeze.flv (in incoming/issue2668) plays fine (with temporary A/V desync that disappears over time) with --nocorrect-pts.

With the default -correct-pts, video freezes after a (massive) time stamp discontinuity.

Audio always plays fine (it doesn't with ffplay).

Video freezes the moment video timestamp jumps to 16910 (audio jumps earlier, leading to desync with -nocorrect-pts, but always plays correctly).
