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.

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).
| 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 |

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.
| 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 |

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.
| 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 |
