Hi, We write large HD video files (MXF) to LTO tape. We want to develop a solution where we can restore a subclip alone from the tape. (This is commonly referred to as PFR - partial file restore)
I understand the -ss and -t options can be used to cut out a subclip - but this is only when the entire file is on disk. Using our tape software we can restore a certain subsection of the file (based on a byte offset, and byte length). I want to know if we can use ffmpeg to convert this into a playable file. I'm guessing we would need some kind of metadata from the original file. So the kind of thing I'm looking for is a command that will let me copy this metadata from the file, before I write it to tape (which I would store on the local disk). I would then want another command which would let me take this metadata + any extracted byte-stream as inputs and produce a playable subclip file as output.
