WindowsVideoRecordingSystem can start late to record when a Record/Start action is executed.

The WindowsVideoRecordingSystem can start to record late when a StartAction is done. Not sure if it starts to record late, or the first seconds of the resulting video are ommited when the mp4 file is created. This normally does not happen in the first record. From Debug done, I can see that as you record more and more, each time takes longer to start recording. The StartRecording action is indeed executed, but the recorded video does not start at the point which StartRecording was called. It can be triggered really easily when multiple recordings are done. Small videos also work, they don't need to exceed the MaximumRecordingSeconds.

1- On a new project, include the HardwareEncoders plugin.
2- Create the functions to StartRecording and EndRecording
3- Record multiple videos and reproduce them. You can see that some of the final record start from 1 to 6 seconds later from when StartRecording was called.
