It avoids leaving dangling pointers behind in memory.
Also remove redundant checks for whether the URLContext to be closed is
already NULL.

The rtmpcrypt protocol requires it.
|
|
This swaps which field is set when the Window Acknowledgement Size
and Set Peer BW packets are received, renames the fields in
order to clarify their role further and adds verbose comments
explaining their respective roles and how well the code currently
does what it is supposed to.
The Set Peer BW packet tells the receiver of the packet (which
can be either client or server) that it should not send more data
if it already has sent more data than the specified number of bytes,
without receiving acknowledgement for them. Actually checking this
limit is currently not implemented.
In order to be able to check that properly, one can send the
Window Acknowledgement Size packet, which tells the receiver of the
packet that it needs to send Acknowledgement packets
(RTMP_PT_BYTES_READ) at least after receiving a given number of bytes
since the last Acknowledgement.
Therefore, when we receive a Window Acknowledgement Size packet,
this sets the maximum number of bytes we can receive without sending
an Acknowledgement; therefore when handling this packet we should set
the receive_report_size field (previously client_report_size).

Also rename comments and log messages accordingly,
and add clarifying comments for some hardcoded values.
The previous names were taken from older, reverse engineered
references.
These names match the official public rtmp specification, and
matches the names used by wirecast in annotating captured
streams. These names also avoid hardcoding the roles of server
and client, since the handling of them is irrelevant of whether
we act as server or client.
The RTMP_PT_PING type maps to RTMP_PT_USER_CONTROL.
The SERVER_BW and CLIENT_BW types are a bit more intertwined;
RTMP_PT_SERVER_BW maps to RTMP_PT_WINDOW_ACK_SIZE and
RTMP_PT_CLIENT_BW maps to RTMP_PT_SET_PEER_BW.

Servers seem to be happy to receive the wrapped-around value as long
as they receive a report, otherwise they timeout.
Initially reported and analyzed by Thomas Bernhard.
|
|
When bytes_read overflowed, last_bytes_read did not yet overflow
and no bytes-read report was created leading to a timeout.

Fix problem to fail by a RTMP Control Message except "Set Chunk Size (1)" after an RTMP handshake. When 'nginx-rtmp-module' relays an RTMP, it sends not only control message 'Set Chunk Size (1)' but also 'Window Acknowledgement Size (5)'.

According to the public RTMP specification, these 4 bytes should
be zero.
librtmp in server mode assumes that the RTMPE (FP9) handshake is
used if these bytes are nonzero.

When acting as server, the server can include a "clientid" property
in some status messages. But this should be a unique number
identifying the client session, not identifying the server itself.
In practice, omitting it works just as well as including this
incorrect field.

avio: Copy URLContext generic options into child URLContexts
Merged-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>
|
|
Since all URLContexts have the same AVOptions, such AVOptions
will be applied on the outermost context only and removed from the
dict, while they probably make sense on all contexts.
This makes sure that rw_timeout gets propagated to the innermost
URLContext (to make sure it gets passed to the tcp protocol, when
opening a http connection for instance).
Alternatively, such matching options would be kept in the dict
and only removed after the ffurl_connect call.

lavf: reorganize URLProtocols
Merged-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>
|
|
This way, the decisions about which protocols are available for use in
any given situations can be delegated to the caller.
|
|
Instead of a linked list constructed at av_register_all(), store them
in a constant array of pointers.
Since no registration is necessary now, this removes some global state
from lavf. This will also allow the urlprotocol layer caller to limit
the available protocols in a simple and flexible way in the following
commits.
