Flussonic Media Server 23.06

• #16405 (new) (Flussonic) Implemented DVR playback for fMP4 format that allows for HEVC (H.265) playback over HLS. Use /{stream-name}/index-{from}-{duration}.fmp4.m3u8 URL to play such DVR; other formats of accessing the archive like rewind are also supported.
• #23113 (new) (Flussonic) Implemented the mechanism for SRT publications with stream name assigned by config_external. Learn more
• #23396 (new) (UI) The number of online streams is now displayed next to the total number of streams for each peer on the Cluster page.
• #26229 (new) (DVR Player) You can now play live and archived H.265 video in our DVR Player on embed.html page and on the Overview tab of the stream profile. fMP4 media container streamed over HLS is used for that.

• #26941 (new) (UI) Added the check for uniqueness of package name for IPTV plugin.
• #29333 (new) (Flussonic API) Implemented response to GET /streams and GET /config in the format suitable for Prometheus applications. Select application/openmetrics-text in the "Response schema" list to learn more.
• #29359 (new) (Flussonic) Supported processing of incoming NAK and ACK packets and resending previously sent packets in our own implementation of SRT protocol that we are currently developing. Packets are forcefully resent upon receipt of NAK.
• #29381 (new) (Flussonic) Fixed the issue with MP4 screenshots from the archive being available in H.264 only. Now you can get such screenshots also in HEVC (H.265) and AV1.
