The process of generating HLS involves the duration (dur) slowly increasing over time until the generated ts files have no video information. Previously, the hls_fragment was set to 10 seconds and hls_window to 60, but it didn't work. After increasing the values, it was able to generate a segment. However, the dur value is very unstable and doesn't gradually increase as configured (around 20 seconds). When it reaches around 40 seconds, the ts files are generated without video, and eventually, the dur value becomes extremely large, causing the ts files to be dropped. Please help identify the issue with this.
