Look for segments in samples in the sample queue matching the data in ptr.
Samples not matching are removed from the queue. If a match is found, the next time it will look for matches starting from the end of the previous matched segment.
- Parameters
-
data data to find matches for in the sample queue len length of the data buffer queue samples used for looking for matching segments pos the offset in data of the matched segment match_sample the number of the sample that contained the match match_offset the offset of the matched segment within the sample match_len the length of the matched segment
- Returns
- 0 if a match was found, < 0 if no match was found

Find matches of needle[n_pos ->] within haystack.
If a sufficiently large match is found, matching bytes before n_pos are included in the match, too (within the limits of the arrays).
- Parameters
-
haystack buffer that may contain parts of needle h_len length of the haystack buffer needle buffer containing source data that have been used to construct haystack n_pos start position in needle used for looking for matches n_len length of the needle buffer match_h_offset_ptr offset of the first matching byte within haystack match_n_offset_ptr offset of the first matching byte within needle match_len_ptr length of the matched segment
- Returns
- 0 if a match was found, < 0 if no match was found

Add a reference to the sample data to the sample queue.
The data is not copied. sample_queue_retain should be called before pkt->data is reused/freed.

Write an RTP hint (that may contain one or more RTP packets) for the packets in data.
data contains one or more packets with a BE32 size header.
- Parameters
-
out buffer where the hints are written data buffer containing RTP packets size the size of the data buffer trk the MOVTrack for the hint track pts pointer where the timestamp for the written RTP hint is stored
- Returns
- the number of RTP packets in the written hint
