static

Find the closest previous frame to the timestamp_pts, in e_old index entries.

Searching for just any frame / just key frames can be controlled by last argument 'flag'. Note that if ctts_data is not NULL, we will always search for a key frame irrespective of the value of 'flag'. If we don't find any keyframe, we will return the first frame of the video.

Here the timestamp_pts is considered to be a presentation timestamp and the timestamp of index entries are considered to be decoding timestamps.

Returns 0 if successful in finding a frame, else returns -1. Places the found index corresponding output arg.

If ctts_old is not NULL, then refines the searched entry by searching backwards from the found timestamp, to find the frame with correct PTS.

Places the found ctts_index and ctts_sample in corresponding output args.

static int64_t add_index_entry ( AVStream *  st, int64_t  pos, int64_t  timestamp, int  size, int  distance, int  flags  )

static

Add index entry with the given values, to the end of st->index_entries.

Returns the new size st->index_entries if successful, else returns -1.

This function is similar to ff_add_index_entry in libavformat/utils.c except that here we are always unconditionally adding an index entry to the end, instead of searching the entries list and skipping the add if there is an existing entry with the same timestamp. This is needed because the mov_fix_index calls this func with the same unincremented timestamp for successive discarded frames.
