* | 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.

* | aacenc: use the fast coder as the defaultRostislav Pehlivanov2018-01-13
| | | | | | | | | | | | | | | | | | | | | | | | The twoloop coder sounds decent at low bitrates, however at higher bitrates it sounds worse than the fast coder (which used to be the old twoloop coder before October 2015) and needs quite a lot more CPU. Change the default to fast. It has been well tested and has had little changes over the years so its been confirmed to be quite stable. Also change its description (not valid for more than a year) and the documentation. Signed-off-by: Rostislav Pehlivanov <atomnuker@gmail.com>

* | lavr: deprecate the entire libraryRostislav Pehlivanov2018-01-04
| | | | | | | | | | | | | | | | | | | | | | | | | | Deprecate the entire library. Merged years ago to provide compatibility with Libav, it remained unmaintained by the FFmpeg project and duplicated functionality provided by libswresample. In order to improve consistency and reduce attack surface, as well as to ease burden on maintainers, it has been deprecated. Users of this library are asked to migrate to libswresample, which, as well as providing more functionality, is faster and has higher accuracy.

* | avformat/hls: enable http_multiple only for http/1.1 serversAman Gupta2017-12-26
| | | | | | | | | | | | | | | | Some http/1.0 implementations, like python's SimpleHTTPServer, can only support one client connection at a time. Making a second request while the first is still connected leads to a deadlock. This change enables multiple connections for http/1.1 servers only, which need to support keepalive by default and should have no problem with concurrent requests.

* | avformat/hls: add http_multiple optionAman Gupta2017-12-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This improves network throughput of the hls demuxer by avoiding the latency introduced by downloading segments one at a time. The problem is particularly noticable over high-latency network connections: for instance, if RTT is 250ms, there will a 250ms idle period between when one segment response is read and the next one starts. The obvious solution to this is to use HTTP pipelining, where a second request can be sent (on the persistent http/1.1 connection) before the first response is fully read. Unfortunately the way the http protocol is implemented in avformat makes implementing pipleining very complex. Instead, this commit simulates pipelining using two separate persistent http connections. This has the advantage of working independently of the http_persistent option, and can be used with http/1.0 servers as well. The pair of connections is swapped every time a new segment starts downloading, and a request for the next segment is sent on the secondary connection right away. This means the second response will be ready and waiting by the time the current response is fully read. Signed-off-by: Aman Gupta <aman@tmm1.net> Signed-off-by: Anssi Hannula <anssi.hannula@iki.fi>
* | avformat/hls: add http_persistent optionAman Gupta2017-12-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This teaches the HLS demuxer to use the HTTP protocols multiple_requests=1 option, to take advantage of "Connection: Keep-Alive" when downloading playlists and segments from the HLS server. With the new option, you can avoid TCP connection and TLS negotiation overhead, which is particularly beneficial when streaming via a high-latency internet connection. Similar to the http_persistent option recently implemented in hlsenc.c Signed-off-by: Aman Gupta <aman@tmm1.net> Signed-off-by: Anssi Hannula <anssi.hannula@iki.fi>
