For the record, was debugging a case of rather bursty muxing of a live stream from a live TV source to fragmented mp4 with keyframe-based fragmentation and subtitles in the mux. For easier debugging I utilized fix_sub_duration with ffmpeg.c, static 2 second GOPs, and added av_gettime_relative logging calls at the end of mov_flush_fragment. It showed things like 2-3 2 second fragments happening in very quick succession, and then a pause for a while. Making the process rather jittery. Haven't yet really been able to look at this patch code wise, but clearly with this patch the output fragmentation becomes much, much more stable (nice ~2 second timings all way through while I was running my tests).
