Steven, I am not sure you understood me correctly or perhaps I did not explain myself optimally.
We still want to split by keyframe in a normal fashion. But, for example, would like the first 5 segments to have an "hls_time" of 1s and the rest of the segments after the first 5 to have an "hls_time" of 5s. An made up option would be (hls_time_initial Seconds,Number) - "-hls_time_initial 1,5 -hls_time 5" The output playlist would contain segments (split at keyframes) 5 segments of length 1s and then any segment after the initial 5 segment would be 5s. Is it clear what I am trying to explain? What do you think? Do you know how this can be achieved?
