Feed data from a user-supplied callback to an AVFifoBuffer.
| f | AVFifoBuffer to write to | |
| src | data source; non-const since it may be used as a modifiable context by the function defined in func | |
| size | number of bytes to write | |
| func | generic write function; the first parameter is src, the second is dest_buf, the third is dest_buf_size. func must return the number of bytes written to dest_buf, or <= 0 to indicate no more data available to write. If func is NULL, src is interpreted as a simple byte array for source data. |

Enlarge an AVFifoBuffer.
In case of reallocation failure, the old FIFO is kept unchanged. The new fifo size may be larger than the requested size.

Return a pointer to the data stored in a FIFO buffer at a certain offset.
The FIFO buffer is not modified.
| f | AVFifoBuffer to peek at, f must be non-NULL | |
| offs | an offset in bytes, its absolute value must be less than the used buffer size or the returned pointer will point outside to the buffer data. The used buffer size can be checked with av_fifo_size(). |
