* lavfi: add filter dnn_detect for object detectionGuo, Yejun2021-04-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Below are the example steps to do object detection: 1. download and install l_openvino_toolkit_p_2021.1.110.tgz from https://software.intel.com/content/www/us/en/develop/tools/openvino-toolkit/download.html or, we can get source code (tag 2021.1), build and install. 2. export LD_LIBRARY_PATH with openvino settings, for example: .../deployment_tools/inference_engine/lib/intel64/:.../deployment_tools/inference_engine/external/tbb/lib/ 3. rebuild ffmpeg from source code with configure option: --enable-libopenvino --extra-cflags='-I.../deployment_tools/inference_engine/include/' --extra-ldflags='-L.../deployment_tools/inference_engine/lib/intel64' 4. download model files and test image wget https://github.com/guoyejun/ffmpeg_dnn/raw/main/models/openvino/2021.1/face-detection-adas-0001.bin wget https://github.com/guoyejun/ffmpeg_dnn/raw/main/models/openvino/2021.1/face-detection-adas-0001.xml wget https://github.com/guoyejun/ffmpeg_dnn/raw/main/models/openvino/2021.1/face-detection-adas-0001.label wget https://github.com/guoyejun/ffmpeg_dnn/raw/main/images/cici.jpg 5. run ffmpeg with: ./ffmpeg -i cici.jpg -vf dnn_detect=dnn_backend=openvino:model=face-detection-adas-0001.xml:input=data:output=detection_out:confidence=0.6:labels=face-detection-adas-0001.label,showinfo -f null - We'll see the detect result as below: [Parsed_showinfo_1 @ 0x560c21ecbe40] side data - detection bounding boxes: [Parsed_showinfo_1 @ 0x560c21ecbe40] source: face-detection-adas-0001.xml [Parsed_showinfo_1 @ 0x560c21ecbe40] index: 0, region: (1005, 813) -> (1086, 905), label: face, confidence: 10000/10000.

* avformat/http,tls: honor http_proxy command line variable for HTTPSMoritz Barsnick2021-03-19
| | | | | | | | | | | | | | | | | | Add the "http_proxy" option and its handling to the "tls" protocol, pass the option from the "https" protocol. The "https" protocol already defines the "http_proxy" command line option, like the "http" protocol does. The "http" protocol properly honors that command line option in addition to the environment variable. The "https" protocol doesn't, because the proxy is evaluated in the underlying "tls" protocol, which doesn't have this option, and thus only handles the environment variable, which it has access to.

* avutil/adler32: Switch av_adler32_update() to size_t on bumpAndreas Rheinhardt2021-03-19
| | | | | | | | | | av_adler32_update() is used by av_hash_update() which will be switched to size_t at the next bump. So it also has to be made to use size_t. This is also necessary for framecrcenc.c, because the size of side data will become a size_t, too.

* lavc: rename AV_CODEC_CAP_AUTO_THREADS->AV_CODEC_CAP_OTHER_THREADSAnton Khirnov2021-03-16
| | | | | | | | | | This cap is currently used to mark multithreading-capable codecs that wrap external libraries with their own multithreading code. The name is highly confusing for our API users, since libavcodec ALWAYS handles thread_count=0 (see commit message in previous commit). Therefore rename the cap and update its documentation to make its meaning clear. The old name is kept deprecated until next+1 major bump.

* avformat/gopher: Add support for Gopher over TLSparazyd2021-03-11
| | | | | | | | | | | | | | | | This commit adds a "gophers" handler to the gopher protocol. gophers is a community-adopted protocol that acts the same way like normal gopher with the added TLS encapsulation. The gophers protocol is supported by gopher servers like geomydae(8), and clients like curl(1), clic(1), and hurl(1). This commit also adds compilation guards to both gopher and gophers, since now there are two protocols in the file it makes sense to have this addition.
