I am experiencing inconsistencies in video duration when using smart recorder element, configured with specific settings below.

#define SMART_REC_CONTAINER NVDSSR_CONTAINER_MP4
#define SMART_REC_CACHE_SIZE_SEC 15
#define SMART_REC_DEFAULT_DURATION 10
#define SMART_REC_START_TIME 2
#define SMART_REC_DURATION 8
#define SMART_REC_INTERVAL 7

resulting in recorded videos varying in length, sometimes being shorter than the specified 8 seconds due to initial frames not always being an Iframe and subsequent drops from the cache. I need guidance on how to consistently generate 8-second videos using smart recorder. Any insights or suggestions to achieve this consistency would be greatly appreciated.

As you know, the lib will start to record after getting a I frame. you can decrease the I frame interval to generate a specified 8 seconds videos.
