Description

With current implementation of cv_ffmpeg asking for a frame after the last key frame results in an error

on cv 2.3.1, line 834 of cap_ffmpeg_impl.hpp should use AVSEEK_FLAG_ANY rather than AVSEEK_FLAG_FRAME

in cv 2.2.0, line 744 of cap_ffmpeg.cpp should be:
int ret = av_seek_frame(ic, video_stream, timestamp, AVSEEK_FLAG_ANY);
rather than:
int ret = av_seek_frame(ic, video_stream, timestamp, 0);
