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.

provides implementation of a wider range of codecs.libavformat
implements streaming protocols, container formats and basic I/O access.libavutil
includes hashers, decompressors and miscellaneous utility functions.libavfilter
provides a mean to alter decoded Audio and Video through chain of filters.libavdevice
provides an abstraction to access capture and playback devices.libswresample
implements audio mixing and resampling routines.libswscale
implements color conversion and scaling routines.
Tools
