pub unsafe extern "C" fn av_fifo_generic_peek(
    f: *mut AVFifoBuffer, 
    dest: *mut c_void, 
    buf_size: c_int, 
    func: Option<unsafe extern "C" fn(arg1: *mut c_void, arg2: *mut c_void, arg3: c_int)>

Feed data from an AVFifoBuffer to a user-supplied callback. Similar as av_fifo_gereric_read but without discarding data. @param f AVFifoBuffer to read from @param buf_size number of bytes to read @param func generic read function @param dest data destination
