    movenc: Add an option for skipping writing the mfra/tfra/mfro trailer · 4f7723cb

    When writing a fragmented file, we by default write an index pointing
    to all the fragments at the end of the file. This causes constantly
    increasing memory usage during the muxing. For live streams, the
    index might not be useful at all.
    
    A similar fragment index is written (but at the start of the file) if
    the global_sidx flag is set. If ism_lookahead is set, we need to keep
    data about the last ism_lookahead+1 fragments.
    
    If no fragment index is to be written, we don't need to store information
    about all fragments, avoiding increasing the memory consumption
    linearly with the muxing runtime.
    
    This fixes out of memory situations with long live mp4 streams.
