john 2b89f7e7e8 Dvr: support h265 flv fragments. v6.0.162 v7.0.24 (#4296) 
1. Issue
When segmenting H.265 encoded FLV files using a DVR, the system does not
create FLV segments at regular intervals as specified by the
`dvr_wait_keyframe` configuration.

2. Configure dvr.segment.conf
```config

listen              1935;
max_connections     1000;
daemon              off;
srs_log_tank        console;
vhost __defaultVhost__ {
    dvr {
        enabled      on;
        dvr_path     ./objs/nginx/html/[app]/[stream].[timestamp].flv;
        dvr_plan     segment;
        dvr_duration    30;
        dvr_wait_keyframe       on;
    }
}
```

3. Stream Push Testing
Domestic FFmpeg version (codecId=12)
```sh
hevc-12-ffmpeg -stream_loop -1 -re -i 264_aac.flv -c:v libx265 -preset fast -b:v 2000k -maxrate 2000k -bufsize 4000k -bf 0 -c:a aac -b:a 128k -ar 44100 -ac 2 -f flv rtmp://localhost/live/livestream
```
FFmpeg version 6.0 or higher (supports `enhanced RTMP`)
```sh
ffmpeg -stream_loop -1 -re -i 264_aac.flv -c:v libx265 -preset fast -b:v 2000k -maxrate 2000k -bufsize 4000k -bf 0 -c:a aac -b:a 128k -ar 44100 -ac 2 -f flv rtmp://localhost/live/livestream
```

OBS streaming (version 30.0 or above supports `enhanced RTMP`)
