Merge pull request #16031 from aDanPin:dm/streaming_auto_meta
G-API-NG/Streaming: don't require explicit metadata in compileStreaming() * First probably working version Hardcode gose to setSource() :) * Pre final version of move metadata declaration from compileStreaming() to setSource(). * G-API-NG/Streaming: recovered the existing Streaming functionality - The auto-meta test is disabling since it crashes. - Restored .gitignore * G-API-NG/Streaming: Made the meta-less compileStreaming() work - Works fine even with OpenCV backend; - Fluid doesn't support such kind of compilation so far - to be fixed * G-API-NG/Streaming: Fix Fluid to support meta-less compilation - Introduced a notion of metadata-sensitive passes and slightly refactored GCompiler and GFluidBackend to support that - Fixed a TwoVideoSourcesFail test on streaming * Add three smoke streaming tests to gapi_streaming_tests. All three teste run pipeline with two different input sets 1) SmokeTest_Two_Const_Mats test run pipeline with two const Mats 2) SmokeTest_One_Video_One_Const_Scalar test run pipleline with Mat(video source) and const Scalar 3) SmokeTest_One_Video_One_Const_Vector test run pipeline with Mat(video source) and const Vector # Please enter the commit message for your changes.

Merge pull request #15216 from dmatveev:dm/ng-0010-g-api-streaming-api
* G-API-NG/Streaming: Introduced a Streaming API Now a GComputation can be compiled in a special "streaming" way and then "played" on a video stream. Currently only VideoCapture is supported as an input source. * G-API-NG/Streaming: added threading & real streaming * G-API-NG/Streaming: Added tests & docs on Copy kernel - Added very simple pipeline tests, not all data types are covered yet (in fact, only GMat is tested now); - Started testing non-OCV backends in the streaming mode; - Added required fixes to Fluid backend, likely it works OK now; - Added required fixes to OCL backend, and now it is likely broken - Also added a UMat-based (OCL) version of Copy kernel * G-API-NG/Streaming: Added own concurrent queue class - Used only if TBB is not available * G-API-NG/Streaming: Fixing various issues - Added missing header to CMakeLists.txt - Fixed various CI issues and warnings * G-API-NG/Streaming: Fixed a compile-time GScalar queue deadlock - GStreamingExecutor blindly created island's input queues for compile-time (value-initialized) GScalars which didn't have any producers, making island actor threads wait there forever * G-API-NG/Streaming: Dropped own version of Copy kernel One was added into master already * G-API-NG/Streaming: Addressed GArray<T> review comments - Added tests on mov() - Removed unnecessary changes in garray.hpp * G-API-NG/Streaming: Added Doxygen comments to new public APIs Also fixed some other comments in the code * G-API-NG/Streaming: Removed debug info, added some comments & renamed vars * G-API-NG/Streaming: Fixed own-vs-cv abstraction leak - Now every island is triggered with own:: (instead of cv::) data objects as inputs; - Changes in Fluid backend required to support cv::Mat/Scalar were reverted; * G-API-NG/Streaming: use holds_alternative<> instead of index/index_of test - Also fixed regression test comments - Also added metadata check comments for GStreamingCompiled * G-API-NG/Streaming: Made start()/stop() more robust - Fixed various possible deadlocks - Unified the shutdown code - Added more tests covering different corner cases on start/stop * G-API-NG/Streaming: Finally fixed Windows crashes In fact the problem hasn't been Windows-only. Island thread popped data from queues without preserving the Cmd objects and without taking the ownership over data acquired so when islands started to process the data, this data may be already freed. Linux version worked only by occasion. * G-API-NG/Streaming: Fixed (I hope so) Windows warnings * G-API-NG/Streaming: fixed typos in internal comments - Also added some more explanation on Streaming/OpenCL status * G-API-NG/Streaming: Added more unit tests on streaming - Various start()/stop()/setSource() call flow combinations * G-API-NG/Streaming: Added tests on own concurrent bounded queue * G-API-NG/Streaming: Added more tests on various data types, + more - Vector/Scalar passed as input; - Vector/Scalar passed in-between islands; - Some more assertions; - Also fixed a deadlock problem when inputs are mixed (1 constant, 1 stream) * G-API-NG/Streaming: Added tests on output data types handling - Vector - Scalar * G-API-NG/Streaming: Fixed test issues with IE + Windows warnings * G-API-NG/Streaming: Decoupled G-API from videoio - Now the core G-API doesn't use a cv::VideoCapture directly, it comes in via an abstract interface; - Polished a little bit the setSource()/start()/stop() semantics, now setSource() is mandatory before ANY call to start(). * G-API-NG/Streaming: Fix STANDALONE build (errors brought by render) |
