Probes a bytestream to determine the input format.
Each time a probe returns with a score that is too low, the probe buffer size is increased and another attempt is made. When the maximum probe size is reached, the input format with the highest score is returned.
| pb | the bytestream to probe, it may be closed and opened again | |
| fmt | the input format is put here | |
| filename | the filename of the stream | |
| logctx | the log context | |
| offset | the offset within the bytestream to probe from | |
| max_probe_size | the maximum probe buffer size (zero for default) |

Appends the media-specific SDP fragment for the media stream c to the buffer buff.
Note, the buffer needs to be initialized, since it is appended to existing content.
| buff | the buffer to append the SDP fragment to | |
| size | the size of the buff buffer | |

| dest_addr | the destination address of the media stream, may be NULL | |
| port | the destination port of the media stream, 0 if unknown | |
| ttl | the time to live of the stream, 0 if not multicast |

| ) |
Assembles a URL string from components.
This is the reverse operation of ff_url_split.
Note, this requires networking to be initialized, so the caller must ensure ff_network_init has been called.
| str | the buffer to fill with the url | |
| size | the size of the str buffer | |
| proto | the protocol identifier, if null, the separator after the identifier is left out, too | |
| authorization | an optional authorization string, may be null | |
| hostname | the host name string | |
| port | the port number, left out from the string if negative | |
| fmt | a generic format string for everything to add after the host/port, may be null |

Splits a URL string into components.
To reassemble components back into a URL, use ff_url_join instead of using snprintf directly.
The pointers to buffers for storing individual components may be null, in order to ignore that component. Buffers for components not found are set to empty strings. If the port isn't found, it is set to a negative value.
| proto | the buffer for the protocol | |
| proto_size | the size of the proto buffer | |
| authorization | the buffer for the authorization | |
| authorization_size | the size of the authorization buffer | |
| hostname | the buffer for the host name | |
| hostname_size | the size of the hostname buffer | |
| port_ptr | a pointer to store the port number in | |
| path | the buffer for the path | |
| path_size | the size of the path buffer | |
| url | the URL to split |
