◆ MOV_calc_frame_index_with_timecode()

int MOV_calc_frame_index_with_timecode	(	MovieReader *	anim,
		IMB_Timecode_Type	tc,
		int	position )

Given a frame index, calculate final frame index taking timecode into account.

This does nothing (returns input frame position) if IMB_TC_NONE is used, or movie proxy/index file is not built.

When a timecode index file is present and is requested to be used, this can return a different frame index than input frame, particularly for IMB_TC_RECORD_RUN_NO_GAPS.

void MOV_close_proxies ( MovieReader * anim )

Close any internally opened proxies of this movie.

◆ MOV_get_existing_proxies()

int MOV_get_existing_proxies ( const MovieReader * anim )

Queries which proxies exist for this movie.

Note that it does not check whether proxies are up to date, or valid files; just merely whether the expected files exist.

Returns bitmask of IMB_Proxy_Size flags.
