Replay

How to replay bug?

Steps to reproduce the bug

Steps to replay the bug:

1. Start the srs application.
2. Start the on_hls service for processing.
3. Check the request parameters for on_hls and observe that the duration in the file parameter is not replaced with the corresponding duration. In the example above, the saved file name is actually 1627019880885-19989.ts.

{'action': 'on_hls', 
'client_id': '3703wn77',

 'seq_no': 77}

Expected Behavior:

Ensure that the markdown structure is maintained.

1627019880885-[duration].ts is replaced with the actual duration. 1627019880885-19989.ts
