\*\*• Hardware Platform (GPU) RTX 3060 \*\*• DeepStream Version 6.0 **• TensorRT Version** \*\*• NVIDIA GPU Driver Version (valid for GPU only) CUDA11.7 **• Issue Type (questions)** 您好，想請問一下使用 Smart Video Record錄影的時候，當下的串流影像是不是就不會繼續存在smart-rec-cache裡面？ 因為我發現我在進行連續錄影的時候，剛剛錄過的影像就沒辦法被smart-rec-start-time所設定的時間錄到。 當我設定smart-rec-start-time=60時 假設我第一次錄影的時段為8:00:00-8:30:00 第二次錄影的時段為8:30:00開始 連續錄影的狀態下我只能錄到8:30:00開始的影像 而無法錄影到8:29:00開始的影像 類似於以下網站的問題,請問現在有改善或有辦法修改嗎？ > [@Smart Record isn't so smart](https://forums.developer.nvidia.com/t/smart-record-isnt-so-smart/177549): > > • Hardware Platform Jetson • DeepStream Version 5.0 • JetPack Version 4.5 • TensorRT Version 7 Hi, I’ve been doing some development with Deepstream and have successfully hooked up the smart record function to MIPI/USB cameras. That is not my complaint. My issue is that the documentation for Smart Record doesn’t make clear there are some major limitations in Smart Record. Specifically, (and I’m guessing this is because it uses a Gstreamer Queue as it’s method of buffering) that once a smar… ---
