* w32pthreads: always use Vista+ API, drop XP supportwm42017-12-26
| | | | | | | | | | | This removes the XP compatibility code, and switches entirely to SWR locks, which are available starting at Windows Vista. This removes CRITICAL_SECTION use, which allows us to add PTHREAD_MUTEX_INITIALIZER, which will be useful later. Windows XP is hereby not a supported build target anymore. It was decided in a project vote that this is OK.

* avformat/hlsenc: Signal http end of chunk(http_shutdown) during ↵Karthick Jeyapal2017-12-25
| | | | | | | | hlsenc_io_close() Currently http end of chunk is signalled implicitly in hlsenc_io_open(). This mean playlists http writes would have to wait upto a segment duration to signal end of chunk causing delays. This patch will fix that problem and improve performance.

* x86inc: AVX-512 supportHenrik Gramner2017-12-24
| | | | | | | | | | | | | | | | | | | | AVX-512 consists of a plethora of different extensions, but in order to keep things a bit more manageable we group together the following extensions under a single baseline cpu flag which should cover SKL-X and future CPUs: * AVX-512 Foundation (F) * AVX-512 Conflict Detection Instructions (CD) * AVX-512 Byte and Word Instructions (BW) * AVX-512 Doubleword and Quadword Instructions (DQ) * AVX-512 Vector Length Extensions (VL) On x86-64 AVX-512 provides 16 additional vector registers, prefer using those over existing ones since it allows us to avoid using `vzeroupper` unless more than 16 vector registers are required. They also happen to be volatile on Windows which means that we don't need to save and restore existing xmm register contents unless more than 22 vector registers are required. Big thanks to Intel for their support.

* avformat/hls: hide misleading warning when http reconnect is requiredAman Gupta2017-12-22
| | | | | | | | | AVERROR_EOF is an internal error which means the http socket is no longer valid for new requests. It informs the caller that a new connection must be established, and as such does not need to be surfaced to the user as a warning. Signed-off-by: Aman Gupta <aman@tmm1.net>
* avformat/http: return EOF from ff_http_do_new_request if previous response ↵Aman Gupta2017-12-22
| | | | | | | | | | | | said Connection:close This fixes a deadlock when using the hls demuxer's new http_persistent feature to stream a youtube live stream over HTTPS. The youtube servers are http/1.1 compliant, but return a "Connecton: close". Before this commit, the demuxer would attempt to send a new request on the partially shutdown connection and cause a deadlock in the tls protocol. Signed-off-by: Aman Gupta <aman@tmm1.net>
* 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.
