Function minimp4_sys::MP4D_open

pub unsafe extern "C" fn MP4D_open(
    mp4: *mut MP4D_demux_t, 
    read_callback: Option<unsafe extern "C" fn(offset: i64, buffer: *mut c_void, size: usize, token: *mut c_void) -> c_int>,

) -> c_int

Parse given input stream as MP4 file. Allocate and store data indexes. return 1 on success, 0 on failure Given file rewind()'ed on return. The MP4 indexes may be stored at the end of stream, so this function may parse all stream. It is guaranteed that function will read/seek sequentially, and will never jump back.
