To keep it simpler this first part includes only non-fragmented use cases if the built-in sample squashing is utilized. Contains the basic mapping code as well as the function that writes out the squashed documents.
Works with both subtitle-only output as well as with other streams. In a separate patch set I will add additional complexity on top by introducing fragmentation matching based on the other streams in the mux (since most things that ingest fragmented MP4 with subtitles want the fragment time ranges to match between the video/audio streams and subtitles in the mux). Changes from v1: * Misc. small changes according to review from Martin. * Removed the {start,end}_ts variables for the packet queue, they are not required for the functionality that is being added currently and simplify the code. * Track start/end calculation based on other tracks was removed. This will become required when fragmentation support is added (as the fragmentation will have to be matched against A/V tracks), but for now a track should only be interested of its own state.
