Sebastian Dröge 2a3d962dc5 fmp4mux: Add support for sub-fragments / chunking 
Allow outputting sub-fragments (chunks in CMAF terms) that are shorter
than the fragment duration and don't usually start on a keyframe. By
this the buffering requirements of the element is reduced to one chunk
duration, as is the latency.

This is used for formats like low-latency / LL-HLS and DASH.

Sebastian Dröge 3172bcd095 fmp4mux: Crank clock for the first fragment in more tests 
Due to how aggregator works, it depends on how buffers are pulled
whether aggregate() is called again or it is waiting for a timeout or EOS:

works:
  - pad 1: 4 buffers, pad 2: 4 buffers
  - aggregate ready: take all 4/4 buffers
  - pad 1: 1 buffers, pad 2: 1 buffer
  - aggregate ready: take all 1/1 buffers

waits:
  - pad 1: 5 buffers, pad 2: 4 buffers
  - aggregate ready: take all 5/4 buffers
  - pad 1: 0 buffers, pad 2: 1 buffer
  - aggregate not ready: waiting for timeout or EOS

Also don't manually set the clock time as that's unnecessary.

Sebastian Dröge 7ac29827d2 fmp4mux: Don't allow VP9 for CMAF 
This would require setting the correct compatible band for VP9 in CMAF,
which is not implemented yet.

Sebastian Dröge 211cd095d6 Add new mux subdirectory for container formats 
Contains the (incomplete) flavors FLV demuxer and the fragmented MP4
muxer for now.
