ov_time_seek_lap

declared in "vorbis/vorbisfile.h";

For seekable streams, ov_time_seek_lap seeks to the given time. This variant of ov_time_seek also automatically crosslaps the transition from the previous playback position into the new playback position in order to eliminate clicking and boundary discontinuities. Otherwise, usage and behavior is identical to ov_time_seek.

ov_time_seek_lap also updates everything needed within the decoder, so you can immediately call ov_read() and get data from the newly seeked to position.

ov_time_seek_lap will lap between logical stream links of differing numbers of channels. Any extra channels from the origin of the seek are ignored; playback of these channels simply ends. Extra channels at the destination are lapped from silence. ov_time_seek_lap will also lap between logical stream links of differing sample rates. In this case, the sample rates are ignored (no implicit resampling is done to match playback). It is up to the application developer to decide if this behavior makes any sense in a given context; in practical use, these default behaviors perform sensibly.

This function does not work for unseekable streams.
