* | avformat/mov: Initialize a potential gap in ctts_data in mov_build_indexMatt Wolenetz2018-03-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | mov_read_ctts ignores ctts entries having count <= 0. Generally, the aggregate of all ctts entries' count fields resulting from mov_read_ctts can be less than the corresponding sample_count. mov_build_index attempts to normalize any existing ctts_data counts to be 1, to make a 1-1 mapping of a ctts_data entry to a sample. That 1-1 mapping left a tail of uninitialized ctts_data entries when the aggregate, normalized ctts_count < sample_count. Even more generally, later usage of ctts_data may depend on the entire ctts_allocated_size having been initialized. This change memsets the entire allocation of the normalized ctts_data in mov_build_index, to prevent use of uninitialized data later.

* | ffmpeg: Fix memset size on ctts_data in mov_read_trun() (round 2)Xiaohan Wang2018-03-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The allocated size of sc->ctts_data is (st->nb_index_entries + entries) * sizeof(*sc->ctts_data). The size to memset at offset sc->ctts_data + sc->ctts_count should be (st->nb_index_entries + entries - sc->ctts_count) * sizeof(*sc->ctts_data)) The current code missed |entries| I believe, which was introduced in https://patchwork.ffmpeg.org/patch/5541/. However, after offline discussion, it seems the original code is much more clear to read (before https://patchwork.ffmpeg.org/patch/5541/). Hence this CL revert the memset logic to it's previous state by remembering the |old_ctts_allocated_size|, and only memset the newly allocated entries.
