It should not be needed for each filter that sets sample aspect ratio to set it explicitly also for each and every frame, instead that is automatically done in get_buffer call. Signed-off-by: Paul B Mahol <onemda@gmail.com>

AVERROR_EOF is an internal error which means the http socket is no longer valid for new requests.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>

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>

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>

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>

This will prevent improper use of ff_http_do_new_request() if the user tries to send a request for a different host to a previously connected persistent http/1.1 connection. Signed-off-by: Aman Gupta <aman@tmm1.net> Signed-off-by: Karthick J <kjeyapal@akamai.com>

This speeds up the filter, and also fixes scene change detection score which is reduced based on the difference of the current MAFD to the preivous MAFD. Obviously if we compare two frames twice, the difference will be 0... Signed-off-by: Marton Balint <cus@passwd.hu>

This is pretty much a requirement for any codec that handles modern codecs like h264, but it was missing. Potentially could lead to issues like missing frames at the end of a stream. Tested-by: Jorge Ramirez <jorge.ramirez-ortiz@linaro.org>
