I have had some work done on captions over on CasparCG, and the dev there has informed me that Softworkz's Subtitle Filtering or something like it is a framework that would make solving the embed/extract problem easier for sidecar and mxf files. The whole set of terminology practice used in this project of referring to captions as a type of subtitle has been a bit confusing to me, as I see them as separate data types. I am sorry that has made it hard to evaluate the various proposed solutions. What progress needs to be made for Subtitle Filtering, or something like it to be ready to merge? What are the specific areas that need updated or cleaned up to allow that to happen? Let's please give specific references to parts of code instead of talking in generality about the patchset unless there are structural changes required. I know there is a history here that I am not fully briefed on, but some structural change like subtitle filtering is needed to solve the broken state of captions support in ffmpeg.
