* avcodec/aacsbr_template: Remove pointless runtime initializationAndreas Rheinhardt2020-12-31
| | | | | | | | | | | | | | | | | The sbr_qmf_window_us array is basically symmetric around its middle element and therefore the latter half is currently initialized from the first half at runtime. Yet because the first half is initialized, the array can't be placed in .bss at all, so that one gains nothing from not already initializing the whole array statically. Therefore this commit does exactly this. (There are two exceptions to the symmetry: Elements 384 and 512 are the negations of their mirror element; for the fixed-point decoder, Q31(-x) does not equal -Q31(x). In order to keep the array exactly the same, the latter form has been used for these two elements.) Reviewed-by: Lynne <dev@lynne.ee> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>

* avcodec/mlpenc: Simplify finding best codebookAndreas Rheinhardt2020-12-31
| | | | | | | | | | | | Finding the best codebook involves comparing different paths, where each path is a sequence of several decisions (namely which codebook to use). Up until now, these sequence was encoded in a NUL-terminated string and the actual decisions were encoded as ’\0'..'\3' (which encoded 0..3). This commit modifies this to actually encode it via 0..3 by switching away from a C-string to a simple array with an explicit length field.

* avcodec/mpeg12: Don't initialize encoder-only parts of RLTableAndreas Rheinhardt2020-12-31
| | | | | | | | | | | ff_mpeg12_init_vlcs() currently initializes index_run, max_level and max_run of ff_rl_mpeg1/2; yet the only user of these fields is the MPEG-1/2 encoder which already initializes these tables on its own. So remove the initializations in ff_mpeg12_init_vlcs(); this also simplifies making ff_mpeg12_init_vlcs() thread-safe.

* hwcontext_drm: make dependency on Linux kernel headers optionalLynne2020-12-30
| | | | | | | | | | This was introduced in version 4.6. And may not exist all without an optional package. So to prevent a hard dependency on needing the Linux kernel headers to compile, make this optional. Also ignore the status of the ioctl, since it may fail on older kernels which don't support it. It's okay to ignore as its not fatal and any serious errors will be caught later by the mmap call.

* avformat/rtsp: add satip_raw flag to receive raw mpegts streamAman Karmani2020-12-28
| | | | | | | | | | | | | | | | | | | This can be used to receive the raw mpegts stream from a SAT>IP server, by letting avformat handle the RTSP/RTP/UDP negotiation and setup, but then simply passing the MP2T stream through instead of demuxing it further. For example, this command would demux/remux the mpegts stream: SATIP_URL='satip://192.168.1.99:554/?src=1&freq=12188&pol=h&ro=0.35&msys=dvbs&mtype=qpsk&plts=off&sr=27500&fec=34&pids=0,17,18,167,136,47,71' ffmpeg -i $SATIP_URL -map 0 -c copy -f mpegts -y remux.ts Whereas this command will simply write out the raw stream, with the original PAT/PMT/PIDs intact: ffmpeg -rtsp_flags satip_raw -i $SATIP_URL -map 0 -c copy -f data -y raw.ts Signed-off-by: Aman Karmani <aman@tmm1.net>
* avformat/rtsp: add support for satip://Aman Karmani2020-12-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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/

* lavu: use address-of operator checking clock_gettimeMarvin Scholz2020-12-28
| | | | | | | | | | | | When targeting a recent enough macOS/iOS version that has clock_gettime it won't be a weak symbol, in which case clang warns for this check as it's always true: warning: address of function 'clock_gettime' will always evaluate to 'true' This warning is silenced by using the address-of operator to make the intent explicit.
