G-API: Introduce a Queue Source #24178 - Added a new IStreamSource class: in fact, a wrapper over a concurrent queue; - Added minimal example on how it can be used; - Extended IStreamSource with optional "halt" interface to break the blocking calls in the emitter threads when required to stop. - Introduced a QueueInput class which allows to pass the whole graph's input vector at once. In fact it is a thin wrapper atop of individual Queue Sources. There is a hidden trap found with our type system as described in https://github.com/orgs/g-api-org/discussions/2 While it works even in this form, it should be addressed somewhere in the 5.0 timeframe. ### Pull Request Readiness Checklist See details at https://github.com/opencv/opencv/wiki/How_to_contribute#making-a-good-pull-request - [x] I agree to contribute to the project under Apache 2 License. - [x] To the best of my knowledge, the proposed patch is not based on a code under GPL or another license that is incompatible with OpenCV - [x] The PR is proposed to the proper branch - [ ] There is a reference to the original bug report and related work - [x] There is accuracy test, performance test and test data in opencv_extra repository, if applicable Patch to opencv_extra has the same branch name. - [x] The feature is well documented and sample code can be built with the project CMake |
