Aman Karmani	98b76bb11f	avformat/rtsp: add support for satip:// The SAT>IP protocol[1] is similar to RTSP. However SAT>IP servers are assumed to speak only MP2T, so DESCRIBE is not used in the same way. When no streams are active, DESCRIBE will return 404 according to the spec (see section 3.5.7). When streams are active, DESCRIBE will return a list of all current streams along with information about their signal strengths. Previously, attemping to use ffmpeg with a rtsp:// url that points to a SAT>IP server would work with some devices, but fail due to 404 response on others. Further, if the SAT>IP server was already streaming, ffmpeg would incorrectly consume the DESCRIBE SDP response and join an existing tuner instead of requesting a new session with the URL provided by the user. These issues have been noted by many users across the internet[2][3][4]. This commit adds proper spec-compliant support for SAT>IP, including: - support for the satip:// psuedo-protocol[5] - avoiding the use of DESCRIBE - parsing and consuming the com.ses.streamID response header - using "Transport: RTP/AVP;unicast" because the optional "/UDP" suffix confuses some servers This patch has been validated against multiple SAT>IP vendor devices: - Telestar Digibit R2 (https://telestar.de/en/produkt/digibit-r1-2/) - Kathrein EXIP 418 (https://www.kathrein-ds.com/en/produkte/sat-zf-verteiltechnik/sat-ip/227/exip-418) - Kathrein EXIP 4124 (https://www.kathrein-ds.com/en/products/sat-if-signal-distribution/sat-ip/226/exip-4124) - Megasat MEG-8000 (https://www.megasat.tv/produkt/sat-ip-server-3/) - Megasat Twin (https://www.megasat.tv/en/produkt/sat-ip-server-twin/) - Triax TSS 400 (https://www.conrad.com/p/triax-tss-400-mkii-sat-ip-server-595256) [1] https://www.satip.info/sites/satip/files/resource/satip_specification_version_1_2_2.pdf [2] https://stackoverflow.com/questions/61194344/does-ffmpeg-violate-the-satip-specification-describe-syntax [3] https://github.com/kodi-pvr/pvr.iptvsimple/issues/196 [4] https://forum.kodi.tv/showthread.php?tid=359072&pid=2995884#pid2995884 [5] https://www.satip.info/resources/channel-lists/	4 years ago

Andriy Gelman	f3891430fc	avformat/rtspdec: fix potential mem leak in listen mode Currently a repeating setup request (with the same stream id) will simply overwrite rtp_handle/transport_priv without freeing the resources first.

Andriy Gelman	423d06e0e2	avformat/rtspdec: add network init to listen mode As per the docs network initialization is required before ff_url_join().

Martin Storsjö	fab8156b2f	avio: Copy URLContext generic options into child URLContexts Since all URLContexts have the same AVOptions, such AVOptions will be applied on the outermost context only and removed from the dict, while they probably make sense on all contexts. This makes sure that rw_timeout gets propagated to the innermost URLContext (to make sure it gets passed to the tcp protocol, when opening a http connection for instance). Alternatively, such matching options would be kept in the dict and only removed after the ffurl_connect call. Signed-off-by: Martin Storsjö <martin@martin.st>	9 years ago
