The IO context is flushed by libavformat/mux.c after writing the header by

If I read avio_write_marker correctly, it won't do an implicit flush on
these calls unless the user actually has set the s->write_data_type
function pointer - which only is set when used by direct API users.
So for normal cases, if I read it correctly, one can't assume
avio_write_marker implies a flush in general.
