It would be nice to have an IMGUI_VIDEO_CAPTURE_ENCODER_PATH definition included in imgui_capture_tool.h much like IMGUI_CAPTURE_DEFAULT_VIDEO_PARAMS[...].  In my world it would be conveniently sourced during ImGuiTestEngine_Postswap;
struct IMGUI_API ImGuiCaptureContext  would contain char* VideoCaptureEncoderPath = IMGUI_VIDEO_CAPTURE_ENCODER_PATH or along those lines so we don't have to input it via the UI.
Thoughts?
