> I tested new functionality that was recently added to FFMPEG to include the
> segment size in bytes and segment duration in the filename. I tried
> re-multiplexing a MP4 with H.264 video and AAC audio into HLS with this
> feature, but only the last HLS segment has this data, all other ts segments
> contained zero data.
