After seeking, packets that you demux should correspond (roughly) to the position you requested. In most cases, the defaults of ``backwards = True`` and ``any_frame = False`` are the best course of action, followed by you demuxing/decoding to the position that you want. This is because to properly decode video frames you need to start from the previous keyframe. .. seealso:: :ffmpeg:`avformat_seek_file` for discussion of the flags. z+Container.seek only accepts integer offset.rN)rZ isinstanceint TypeErrortyperAVSEEK_FLAG_BACKWARDAVSEEK_FLAG_ANYAVSEEK_FLAG_FRAMEAVSEEK_FLAG_BYTErlrr av_seek_framerr flush_buffers) roffsetr|r}rNr~rc_offsetflagsrqrLs rseekzInputContainer.seeksJ &#&I4PV<X X"  S-- -E  S(( (E $ S** *E " S)) )E396<c|j|jD]!}|j}|s|j#yrT)rZrrPr)rrNrPs rrzInputContainer.flush_buffers4s=  ll .F"00M++- .rX)__name__ __module__ __qualname__rRrVpropertyr[r^r`rdrfrxrzrbintr rcfuncrrXrr r sP d'' %% !!**Y@v*!%!& $05/4>++ > ;; >  >#)++>"(>@ \\ . .rXr )r cython.cimports.av.codec.contextrr$cython.cimports.av.container.streamsrcython.cimports.av.dictionaryrcython.cimports.av.errorrcython.cimports.av.packetrcython.cimports.av.streamr r cython.cimports.av.utilsr cython.cimports.libc.stdintr r cython.cimports.libc.stdlibrrrr rfinalcclass ContainerrrXrrsp M@4.,9384ne.Ye.e.rX
