    f: *mut AVFifoBuffer,

Feed data at specific position 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 offset offset from current read position @param buf_size number of bytes to read @param func generic read function @param dest data destination
