[FFmpeg-cvslog] avisynth: Fix setting stream timebase

[Marton Balint]

ffmpeg | branch: master | Marton Balint <cus at passwd.hu> | Mon Aug  8 19:24:18 2016 -0400| [bcefafa226dcda23d4d9af9601d19389cb918a5b] | committer: Diego Biurrun

avisynth: Fix setting stream timebase

Stream timebase should be set using avpriv_set_pts_info, otherwise
avctx->pkt_timebase is not correct, leading to A/V desync.
