* 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>

* | mpegts: add fix_teletext_pts mpegts demuxer optionMarton Balint2013-08-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Changes since v1 of the patch: - enable option by default - add documentation - move up PTS override code after PES header parsing, to ensure we use the last PCR before the first packet of the teletext PES packet. The option overrides teletext packet PTS and DTS values with the timestamps calculated from the PCR of the first program which the teletext stream is part of and is not discarded. Using the same teletext PID for multiple programs is possible, therefore we need some kind of heuristics to know which program PCR we should synchronize to. Using the first non-discarded PCR pid among the programs of the teletext stream seemed like a good choice. The patch does not do PCR interpolation to estimate the PCR of the teltetext packet, it just uses the last PCR of the program, which may cause a slight error (0.1 sec) in the teletext packet pts-es.
