Change the hls_aof_ratio to 2.1. v5.0.200 (ossrs#3886)

In pure audio mode, there are no keyframes. Therefore, we can only rely on the length of the slice to determine whether it should be output. `hls_aof_ratio` is the coefficient that, once reached, will generate a new slice. In scenarios with video, if the `hls_aof_ratio` is too small, for example 1.2, and the GOP (Group of Pictures) is 10 seconds, then a slice will definitely be generated at 12 seconds. At this point, if there are no keyframes, it will cause the next slice to start with a non-keyframe. A safer coefficient is twice the GOP (Group of Pictures). This way, it won't trigger incorrectly and prevent the individual transcoding of a ts segment file. --------- Co-authored-by: Haibo Chen <[email protected]>
