Can't play the segment timeline stream

[TuanTranBPK]

On server side, choose either stream C using GPAC multicast server. Alternatively, use external multicast server that sends the segment timeline multicast stream. On the gateway side, use GPAC multicast gateway to receive the multicast stream and serve to the player. In the test dash.js player is used.

When using external multicast server, when the player requests the audio/video segments after obtaining the manifest and init segments, the player gets 404. Looking at the multicast gateway logs, the segments have been received and decoded. However they have been removed out of cache (check the attached log with keyword "110000-75931995807033.dash")
