| | | | | | | | | | | | | | | | | | | | | | | | | | | | merge from libav: 585dc1aecef0371ad6f16cb3750ae2a6da9cf00a If the metadata packet is corrupted, flv_read_metabody can accidentally read past the start of the next packet. If the start of the next packet had been flushed out of the IO buffer, we would be unable to seek to the right position (on a nonseekable stream). Prefer to clearly error out instead of silently trying to read from a desynced stream which will only be interpreted as garbage. Signed-off-by: Steven Liu <lq@chinaffmpeg.org>

* | avformat/mov: prevent duplication of first fragment's ctts_dataDaniel Glöckner2017-09-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | MP4 files with fragments might have the first moof box that is mentioned in a fragment index before the first mdat box. Since it is then already parsed by mov_read_header, we have to make sure that mov_switch_root will not parse it again when seeking by setting the headers_read flag in the index. Parsing it a second time would cause the ctts_data array to receive a second copy of the information from the trun box, leading to wrong PTS values for the second and following fragments in presence of B-frames.

* | avformat/mov: Bail when invalid sample data is present.Dale Curtis2017-09-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ctts data in ffmpeg relies on the index entries array to be 1:1 with samples... yet sc->sample_count can be read directly from the 'stsz' box and index entries are only generated if a chunk count has been read from 'stco' box. Ensure that if sc->sample_count > 0, sc->chunk_count is too as a basic sanity check. Additionally we need to check that after the index is built we have the right number of entries, so we also check in mov_read_trun() that sc->sample_count == st->nb_index_entries.

* | avformat/concatdec: add fallback for calculating file durationJustin Ruggles2017-08-31
| | | | | | | | | | | | | | | | | | If a file does not have a known duration, this leads to the timestamps starting over for the next file, causing non-monotonic timestamps.

* | avformat/mov: Fix trampling of ctts during seeks when sidx support is enabled.Dale Curtis2017-08-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When sidx box support is enabled, the code will skip reading all trun boxes (each containing ctts entries for samples inthat box). If seeks are attempted before all ctts values are known, the old code would dump ctts entries into the wrong location. These are then used to compute pts values which leads to out of order and incorrectly timestamped packets. This patch fixes ctts processing by always using the index returned by av_add_index_entry() as the ctts_data index. When the index gains new entries old values are reshuffled as appropriate. This approach makes sense since the mov demuxer is already relying on the mapping of AVIndex entries to samples for correct demuxing. As a result of this all ctts entries are now 1-count. A followup change will be submitted to remove support for > 1 count entries which will simplify seeking. Notes for future improvement: Probably there are other boxes (stts, stsc, etc) that are impacted by this issue... this patch only attempts to fix ctts since it completely breaks packet timestamping. This patch continues using an array for the ctts data, which is not the most ideal given the rearrangement that needs to happen (via memmove as new entries are read in). Ideally AVIndex and the ctts data would be set-type structures so addition is always worst case O(lg(n)) instead of the O(n^2) that exists now; this slowdown is noticeable during seeks.
