This may not be completely unreasonable but some comments are still necessary: The sentence sounds to me as if the the filter pipeline always assigns timestamps to frames, but this is neither true (many filters do not care about timestamps and you do not have to insert a filter which does) nor does it make the filter pipeline special: Timestamps often come from the demuxer and / or the decoder and may or may not change in the filterchain (and - as I believe you realized by now - because of the chosen output format; and also the chosen encoder - for which you did not post a question yet). Frames may not have a timestamp assigned - you posted the relevant part of the documentation. Concerning some of your other comments: The timestamps in MPEG streams may be negative. There is no AVFrac in the (current) codebase.
