Merge pull request #22248 from cudawarped:ffmpeg_rtsp_low_fps 
* Allow the number of threads FFMpeg uses to be selected during VideoCapture::open().
Reset interupt timer in grab if
err = avformat_find_stream_info(ic, NULL);
is interupted but open is successful.

* Correct the returned number of threads and amend test cases.

* Update container test case.

* Reverse changes added to existing videoio_container test case and include test combining thread change and raw read in the newly added videoio_read test case.

1f0bfc8d83 Fix angle discretization in Hough transforms 
In some situations the last value was missing from the discrete theta
values. Now, the last value is chosen such that it is close to the
user-provided maximum theta, while the distance to pi remains always
at least theta_step/2. This should avoid duplicate detections.

A better way would probably be to use max_theta as is and adjust the
resolution (theta_step) instead, such that the discretization would
always be uniform (in a circular sense) when full angle range is used.
