--- title: Changelog url: https://doc.pstreamer.tv/en/manual/whats_new.html lang: en product: Perfect Streamer version: 1.13.3.445 --- # Changelog ## version 1.13.3.445 Beta *02.06.2026* - **OTT (Low-Latency HLS / DASH over CMAF)**: a new *OTT/HLS/LL-HLS/LL-Dash* delivery mode (*ott-hls = 3*) — the built-in multiplexer produces fragmented **MP4** / **CMAF** (*fMP4*), on top of which **MPEG-DASH** (now over CMAF instead of MPEG-TS) and Low-Latency **HLS** are delivered on a new endpoint (path *…/llhls/…*). The player starts playback without waiting for the full segment: the **LL-HLS** media playlist is split into *partial segments* («parts»), and blocking playlist reload (the server holds the request until the next part is ready) and the *EXT-X-PRELOAD-HINT* preload hint are used. - **OTT (Low-Latency: settings and synchronization)**: the target duration of a part is set by the *Part Target Duration* setting (ms, applied on the fly without restarting the stream); the *Enable TS Chunk* option determines whether legacy MPEG-TS **HLS** (playlist *…/hls/…*) is emitted in parallel — when disabled, only fMP4 segments go to disk and CPU. For precise low latency, *Producer Reference Time* (*prft*) and *UTCTiming* have been added to the manifests, binding the media time to **UTC**. - **DVR (subsystem launch)**: a persistent on-disk archive is written in parallel with the built-in live segmenter for **HLS** / **MPEG-DASH OTT**, using the same segmentation and the same OTT-session URLs — the playback mode is switched by a query parameter. In *OTT/HLS/LL-HLS/LL-Dash* mode the archive maintains two independent indexes — one for MPEG-TS chunks and one for fMP4 / CMAF segments — so VOD is served in the same container as live. [Full DVR description](manual.md#dvr). - **DVR (playback)**: VOD over **HLS** and **MPEG-DASH** via the query parameters *t=* (start moment, *t=0* — from the beginning of the archive) and *d=* (window duration, empty or *0* — “up to the present moment”), as well as binding to **EPG** via *epg=* (the server itself substitutes the *start* and *duration* of the active event as the window boundaries). A closed **HLS** VOD playlist with the markers *EXT-X-PLAYLIST-TYPE:VOD* and *EXT-X-ENDLIST*; a static **DASH MPD** (*@type=”static”*, fixed *mediaPresentationDuration*) with automatic splitting into several *Period* elements at recording gaps. Requests beyond the archive are normalized to the available boundaries without errors. - **DVR (adaptive VOD)**: for adaptive **HLS** and **DASH** groups, only variants bound to DVR storage are included in the manifest, each quality is a separate *Representation* inside the shared *Period* elements, and quality switching works without re-opening the manifest. - **DVR (protection and delivery)**: while a VOD session is open, size-based and sliding-window cleanup do not touch the chunks within its window (the protection is released on timeout or *FIN*); a transparent VOD → live-edge transition if the player reaches the right boundary of the window — the segment is served from live memory without redirects; the VOD-playlist cache serves repeated requests for the same *index.m3u8* / *index.mpd* byte-for-byte identical (convenient for **CDN**). - **DVR Storage (storage settings)**: several simultaneous storages, each with a *Max Usage* threshold, a *Cleanup Interval* period, *Disk Pressure Grace* debounce, a *Disk Pressure Cut* upper limit on deletion per cycle, a *Disk Emergency Bytes* emergency threshold and *Ready* / *Error* states. - **DVR (stream settings)**: *Storage Hours* — archive depth in hours with sliding-window cleanup (the upper bound is fixed at 90 days), and *Storage Min Hour* — a protected lower bound that size-based cleanup does not remove even under disk pressure. - **DVR (subtitles)**: **WebVTT** is recorded to the archive in parallel with the TS chunks, with a per-PID index; the VOD subtitle playlist is served at the same URLs (for **DASH** the *X-TIMESTAMP-MAP* header is stripped on the fly). Subtitle chunks without cues are not written to disk — a zero-size chunk is synthesized on read, which reduces the file-system load on channels with sporadic subtitles. - **DVR (maintenance)**: a background collector of “orphaned” files (the initial run is about a minute after startup, then hourly and on *disk pressure*; protection against a race with the writer by mtime), monotonic chunk numbering across service restarts; fixed a mode in which the background size-based cleanup and the collector could fail to start. - **DVR (observability and monitoring)**: *GET /data/dvr-storage-list* returns, for each storage, *State*, *Total / Free / Used Bytes*, *Used %*, *Archived Bytes*, *Pressure Since Sec*, the indicator of an active background operation (*active-task*: *gc-orphans* / *disk-pressure-trim* / *none*) with its duration and details of the most recent cleanup runs, as well as a list of bound streams with the attributes *retention-hours*, *archived-sec*, *archived-bytes* and *active*; the archive size is additionally broken down by container (TS / MP4). At the stream level, *GET /data/stream/* exposes the *storage-gap-percent* metric (the percentage of time gaps in the archive), and its histogram by time buckets is served by the new endpoint *GET /data/dvrstat* — for rendering the DVR-archive timeline in the admin UI with markup of recording events and subtitle activity. - **OTT (IDR-based segmentation)**: **HLS** and **MPEG-DASH** segmentation distinguishes an *IDR* from an ordinary *I-frame* in **H.264** / **HEVC** streams. On closed-GOP content the segment boundaries are aligned to IDR — each chunk begins with a genuine random access point (*SPS+PPS+IDR*, and in **HEVC** also accounting for the separate *VPS* NAL), and the player is guaranteed to open the stream from any segment; on open-GOP / IDR-less sources the nearest I-frame serves as the boundary. - **OTT (analyzer metrics)**: new metrics on the video stream — *idr-int-max / avg* (IDR interval) and *kf-int-max / avg* (GOP interval). From their ratio the administrator immediately sees the type of GOP structure: closed-GOP (*idr-int ≈ kf-int*) or open-GOP (*idr-int* absent). The XML/JSON key names remain the same for backward compatibility. - **OTT HLS (playlist)**: *EXT-X-VERSION* is chosen by default according to the HLS mode — *OTT/HLS* and *OTT/HLS/LL-HLS/LL-Dash* yield *EXT-X-VERSION:6* with *EXT-X-INDEPENDENT-SEGMENTS* and the *CHARACTERISTICS* attribute in *EXT-X-MEDIA TYPE=SUBTITLES* (in *OTT/HLS/LL-HLS/LL-Dash* the legacy master *…/hls/…* also emits a subtitle *EXT-X-MEDIA*), *Peering/HLS* — *EXT-X-VERSION:3* for compatibility with older clients (the `?v=` query parameter overrides the default). The *EXT-X-TARGETDURATION* value now reflects the maximum actual segment duration (section 4.3.3.1 of **RFC 8216**), not the *chunk-min-interval* setting — with GOP-aligned segmentation the manifest does not violate the standard, and *hls.js* does not halve the playlist refresh interval and does not raise false *bufferStalledError*. - **HTTP/3 (QUIC)**: a built-in server based on **ngtcp2** + **nghttp3** serves **HLS** and **MPEG-DASH** over **QUIC** — enabled by the web server’s *HTTP/3 Enable* setting (port *HTTP/3 Port*, UDP, by default matching the HTTPS port), supports *0-RTT*. Low-Latency **HLS** / **DASH** are delivered over **QUIC** incrementally (chunked) — *parts* are sent to the client as they become ready, without waiting for the full segment. Only OTT routes are accepted on the QUIC transport; administrative paths remain on HTTPS/HTTP. The client’s real IP is passed via the internal `x-pss-peer-addr` header and is counted toward active peers without being replaced by the loopback address. Switching **HLS** / **DASH** to **HTTP/3** is also activated by the *?h3* query parameter — for test-switching an individual session without reconfiguring the client. - **Active peers**: a uniform OTT-session timeout of 60 seconds independent of transport; client-record updates on scheme change happen only “upward” by priority (`http` → `https` → `quic`). The *ott-type* attribute in *http-clients* now carries a composite value of the form `/` (*PROTO* = *HLS* / *DASH* / *HTTP*; *scheme* = *http* / *https* / *quic*) — the admin UI sees both the OTT protocol and the actual network transport of each client. - **PS1 output**: smooth handling of stream-input switching has been implemented on the *PS1* output. On a queue spike at source switching, the oldest packets are silently dropped, while client seqID / TS values remain continuous — receiving peers get by with the standard retr mechanism instead of re-initialising the connection with *StateError*. The dropped-packet counter is visible in the extended PS1-output statistics. - **RTMP / RTMPS (publishing to YouTube / Facebook)**: publishing **SPTS** to any RTMP endpoint — *YouTube*, *Facebook*, etc. Single-program format: one video **H.264** / **HEVC** and no more than one **AAC** audio track; a multi-track source is narrowed via *mpegts-pid-accept* / *mpegts-pid-reject*. **HEVC** is published via **Enhanced RTMP** (the *allow-hevc* option, enabled by default; when disabled — only **H.264**). Incompatible track layouts are not published but are reported in the statistics (*compatible*, *incompat-reason*, *video-codec*, *audio-codec*, *dropped-tracks*). For *rtmps*, Perfect Streamer connects as a **TLS** client (there is no server certificate; certificate verification is the *tls-verify* option, disabled by default). Settings: *url*, *bind-if* (local interface / IP of the outgoing connection), *client-timeout*, *allow-hevc*, *tls-verify*, *trace*. - **RTMP / RTMPS (reception, pull)**: Perfect Streamer connects as an RTMP client to an *rtmp(s)://* source and pulls the stream (pull); FLV is remultiplexed into **MPEG-TS**. **SPTS** only; there is no listening / publication-ingest mode (listen / push-ingest). Settings: *url*, *bind-if*, *client-timeout*, *tls-verify*, *trace*. In *GET /data/stream/* — the connection state and reception counters (*rtmp-state*, *recv-frames*, *read-errors*). - **SPTS / TR 101 290**: a PCR drift compensator is now active on input streams — slow drift of the source reference oscillator relative to the local clock is absorbed by a soft *sync DT* offset in the background, with no visible hiccups on the output. Controlled by the stream settings *Sync Drift Compensation* (on by default) and *Sync Drift Soft Window* (ms). - **SPTS / TR 101 290**: a wide-window PCR linear regression measures *drift* (ppm) and *PCR accuracy* (ns per section *P2.3*) against the reference rate. The metrics *pcr-drift-max / avg*, *pcr-acc-max-ns*, as well as the intervals *pcr-int*, *pat-int*, *pmt-int* are exposed in *GET /data/stream/* and written to the historical-statistics DB (the new tables are visible to *Resetting Stat*). - **SPTS / T-STD**: a reference-decoder video buffer analyzer (**T-STD**, **ISO/IEC 13818-1** §2.4.2). The *MBn* capacity is picked from the *stream type* of the video PID; the drain rate stabilizes within a 1-second “warm-up” timed by the PCR clock (not by the host system clock — so the analyzer does not react to CPU scheduler pauses). The counters *tstd-video-overflows / underflows / max-fill / drain-bps* are exposed in *GET /data/stream/* and feed into *tr101290-alert*. - **SPTS**: runtime multiplex bitrate-mode detector — the *bitrate-mode-detected* attribute (*cbr* / *vbr* / *unknown*) based on comparing the 5-second and 60-second bitrates. The *pcr-acc* and *tstd-video* checks in *tr101290-alert* are automatically suppressed on detected *VBR*, where they would otherwise produce false positives. - **Ad-insertion analyzer**: on the input **SPTS** stream a codec «passport» is built — a video passport (full *SPS*, **H.264** / **HEVC** profile and level) and an audio passport (**MPEG Audio**, **AC-3**, **AAC** in *ADTS* and *LATM* formats) — and **SCTE-35** sections (*splice_info_section*) are parsed with splice-point markup. In *GET /data/stream/* (when continuous **SPTS** analysis is enabled), access- and splice-boundary signals are reported — *GOP*, *RAI*, *splice-point*, **SCTE-35** events; the *Splice Point Notify At* setting sets the lead time of the insertion-point notification. The data is prepared for server-side ad insertion. - **AI complaint helper**: a new endpoint *GET /data/stream//ai-complaint-prompt* returns a ready-made English-language prompt for any chat model, instructing the model to compose an official complaint letter to the provider that lists the detected **TR 101 290** / **ISO/IEC 13818-1** violations. The prompt carries exactly the same tokens and measured values as *tr101290-alert*; the stream name and source URI do not enter the prompt — the placeholder ** is used, which the operator fills in manually. The language of the letter is chosen in the answer to the prompt. - **Web portal (roles)**: server settings, EPG and management of the administrator account list are allowed only for the *Admin* role; the *RestrictAdmin* role can pause streams and channels but cannot change the other settings; the *Viewer* role is view-only. *POST* routes are closed by default, and any new HTTP operation requires explicit permission for a reduced role — access is not expanded silently. - **Server (memory)**: periodic return of free memory from *glibc* arenas to the system (*malloc_trim* every 30 s) and limiting the number of arenas via the *MALLOC_ARENA_MAX* environment variable in the *systemd* unit — eliminates the gradual growth of *RSS* during long-running operation with dozens of streams, without logical leaks. - **MPEG-TS filter**: the *Filter Teletext* setting again drops both types of teletext PES streams (classic and subtitles) after internal reclassification in the analyzer. - **MPTS input**: the **RTSP** transport has been removed from the list of those allowed for MPTS — **RTSP** is single-program and is applicable only as an SPTS source. - Other bugfixes and improvements. ## version 1.12.3.433 *09.05.2026* - DVB scanner for **DVB-S/S2**, **DVB-C** and **DVB-T/T2**: transponder discovery and program-list compilation, with the option to apply the discovered parameters directly in the DVB adapter settings. - DVB scanner: transponder reference data is loaded from *Enigma2*-format files (*satellites.xml*, *cables.xml*, *terrestrial.xml*) located in the settings directory. - DVB scanner: *blind scan* mode for **DVB-S/S2** and **DVB-C/T/T2** — iteration over frequencies, polarizations and symbol rates without a transponder reference. - DVB scanner: each discovered program reports *PNR*, service name, provider, the *scrambled* flag (derived from *free_CA_mode* in the **SDT** with a fallback via **PMT**), and the main *PID* values (video, audio, *PCR*). - Hardware **BISS-1** and **BISS-E** descrambler for receiving encrypted channels from DVB cards. Keys are assigned per program or per individual *PLP* in **T2-MI** mode; both key formats are supported (12 or 16 hex characters, with automatic verification of **BISS-1** check bytes). - Multi-stream **T2-MI** support (*ETSI TS 102 773*): multiple *T2-MI carriers* on a single transponder, per-service PLP selection, automatic and manual *carrier PID* selection modes, filtering by *TSID*. - **MPEG-DASH** support on the **HLS OTT** output: generation of an *MPD* manifest of the *mp2t-simple* profile sharing the same segments as **HLS**. - **WebVTT** subtitle support in **HLS OTT**: automatic decoding of teletext subtitles, segmentation of the subtitle track on **HLS** segment boundaries and its publication in the playlist. Controlled by the per-stream *ott-webvtt* option. - Teletext-based subtitle decoder (**ETSI EN 300 706**): full national-alphabet tables, correct stitching of page lines, and delivery of subtitles to the player. - **MPTS** multiplexer: automatic *Service Type* detection from the *PMT* (HD/SD H.264, HEVC, MPEG-2, digital radio, etc.) with the option of a manual override via the *Service Type* setting. - **MPTS** multiplexer: manual PID remapping (*mpegts-pid-old* / *mpegts-pid-new*) with collision protection during automatic PID selection for neighbouring elementary streams. - **MPTS** multiplexer: pass-through of service elementary streams (*DSM-CC*, *AIT*, **SCTE-35**) marked with the corresponding descriptors in the *PMT* — previously such streams were unconditionally filtered out. - **MPTS** multiplexer: the upper limit of the aggregate bitrate has been raised from 64 to 128 Mbit/s. - *DVR Storage* settings section: attaching DVR storages and binding them to **SPTS** streams (the *dvr-storage* parameter) — groundwork for the recording functionality. - Support for ASI devices. - Transcoder: support for streams without IDR frames. - Transcoder: 5.1 audio encoder loudness-correction profile.

More details on receiving SRT from Perfect Streamer in Flussonic software [FAQ](faq.md#flussonicsrt). Due to changes in the video card identification mechanisms, it will be necessary to re-bind the video cards in the transcoder. To do this, you need to open the transcoder-output settings, make sure that the correct device (Device ID) is selected, and save the settings regardless of whether the selected device has changed or not. ## version 1.10.1 *30.06.2025* - Adaptive HLS generation.
