* configure: Use a separate config_components.h header for $ALL_COMPONENTSMartin Storsjö2022-03-16
| | | | | | | | This avoids unnecessary rebuilds of most source files if only the list of enabled components has changed, but not the other properties of the build, set in config.h. Signed-off-by: Martin Storsjö <martin@martin.st>
* Remove unnecessary libavutil/(avutil|common|internal).h inclusionsAndreas Rheinhardt2022-02-24
| | | | | | | | | | Some of these were made possible by moving several common macros to libavutil/macros.h. While just at it, also improve the other headers a bit. Reviewed-by: Martin Storsjö <martin@martin.st> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For cases with dual stack (IPv4 + IPv6) connectivity, but where one stack potentially is less reliable, strive to trying to connect over both protocols in parallel, using whichever address connected first. In cases with a hostname resolving to multiple IPv4 and IPv6 addresses, the current connection mechanism would try all addresses in the order returned by getaddrinfo (with all IPv6 addresses ordered before the IPv4 addresses normally). If connection attempts to the IPv6 addresses return quickly with an error, this was no problem, but if they were unsuccessful leading up to timeouts, the connection process would have to wait for timeouts on all IPv6 target addresses before attempting any IPv4 address. Similar to what RFC 8305 suggests, reorder the list of addresses to try connecting to, interleaving address families. After starting one connection attempt, start another one in parallel after a small delay (200 ms as suggested by the RFC). For cases with unreliable IPv6 but reliable IPv4, this should make connection attempts work as reliably as with plain IPv4, with only an extra 200 ms of connection delay.

* | avformat: make avformat_network_init() explicitly optionalwm42018-01-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It was sort of optional before - if you didn't call it, networking was initialized on demand, and an ugly warning was logged. Also, the doxygen comments threatened that it would be made strictly required one day. Make it explicitly optional. I would prefer to deprecate it fully, but there might still be legitimate reasons to use this. But the average user won't need it. This is needed only for two reasons: to initialize TLS libraries like OpenSSL and GnuTLS, and winsock. OpenSSL and GnuTLS were already silently initialized on demand if the global network init function was not called. They also have various thread-safety acrobatics, which make concurrent initialization within libavformat safe. In addition, the libraries are moving towards making their global init functions safe, which removes all need for central global init. In particular, GnuTLS 3.5.16 and OpenSSL 1.1.0g have been found to have safe init functions. In all cases, they use internal reference counters to avoid that the global uninit functions interfere with concurrent uses of the library by other API users who called global init. winsock should be thread-safe as well, and maintains an internal reference counter as well. Since we still support ancient TLS libraries, which do not have this fixed, and since it's unknown whether winsock and GnuTLS reinitialization is costly in any way, don't deprecate the libavformat functions yet.
* | http: block while waiting for reconnectingwm42018-01-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It makes no sense to return an error after the first reconnect, and then somehow resume the next time it's called. Usually this will lead to demuxer errors. Make reconnecting block instead, until it has either successfully reconnected, or given up. Also make the wait reasonably interruptible. Since there is no mechanism for this in the API, polling is the best we can do. This behaves roughly the same as other interruptible network functions in libavformat. (The original code would work if it returned AVERROR(EAGAIN) or so, which would make retry_transfer_wrapper() repeat the read call. But I think having an explicit loop for this is better anyway.) I also snuck in a fix for reconnect_at_eof. It has to check for AVERROR_EOF, not 0.

| * tls: Hide backend implementation details from usersDiego Biurrun2017-06-02
| | | | | | | | | | | | | | | | TLS is currently implemented over either OpenSSL or GnuTLS, with more backends likely to appear in the future. Currently, those backend libraries are part of the protocol names used during e.g. the configure stage of a build. Hide those details behind a generically-named declaration for the TLS protocol to avoid leaking those details into the configuration stage.
