Corrected RTP timestamps when synchronized on PTP

1.17

(Preview - 2025-01-10)

Delay: be sure to have always the same delay for the watermarking audio across restart

1.16

(Preview - 2024-11-26)

RTSP: Correct URL escaping, handle OPTIONS

1.15

(Preview - 2024-07-03)

Web Interface : protect combo for invalid values, which can prevent the interface from displaying (on a change of Kantar License for instance).

1.14

(testing - 2024-05-28)

AES67: HTTP requests for RTSP corrections

by-id starts at 1 for channel 1 (instead of 0)
Correct support for /by-name/

1.13

(2022-10-12)

AES67: interface allows multiline SDP to be entered.

AES67: RTSP server supports HTTP request to get the SDP with http://<SOUND4_WM2_IP>:8854/by-id/<stream number>

⚠️

BUG: /by-id/ numbers start at 0 instead of 1

1.12

(Preview 2022-09-12)

More detailed information on PTP clock and synchronization.

1.11

(2022-10-07)

Force the rate of NTP requests after an upgrade without needing to change the NTP servers

1.10

(Public - 2022-09-22)

Reduce rate of NTP requests in local networks, to avoid being rejected.

Correct AES67 daemon crash when SAP source is lost

Correct AES67 releasing of unused slots, to avoid "command failed" when starting the 65th AES67 stream
