MistServer Changelog

Development builds

These will be in the next release

• TBA

3.2 (Stable Release)

• Feature: Added support for passing through TS data raw from TS-based inputs (TS SRT, TS RIST, TS UDP, TS TCP, file descriptors) to TS-based outputs (TS SRT, TS RIST, TS UDP, TS TCP, HLS)
• Feature: Our generic "URIReader" now supports S3-based URLs for reading (thanks Alex Kordic!)
• Feature: MP4 input now reads through the URIReader (adds HTTP(S) and S3 read support to MP4 VoD input)
• Feature: EBML (MKV/WebM, Matroska) input now reads through the URIReader (adds HTTP(S) and S3 read support to MKV/WebM VoD/live input)
• Feature: HLS as well as raw TS file input now read through the URIReader (adds HTTP(S) and S3 read support to HLS/TS VoD/live input)
• Feature: Our new "sessions" system, which unifies the concept of what a single "viewer" is into something that can be configured based on your own preferences, rather than hardcoded assumptions/defaults
• Feature: Added ATHEIST environment variable, that when set, disables all angel processes (mostly useful to ease debugging)
• Feature: Can now push to HLS-style playlists (containing any supported push-output file format! e.g. .ts, .mkv, .webm, .aac, .flv) with custom segmenting and playlist filename patterns as well as custom segment target durations
• Feature: Custom variables can now be defined, that take their values from configuration and/or external URLs and/or external binaries. These can be used in all places where variables can already be used in the system
• Feature: Added capability system for support push output GET parameters (both generic/global and per-output)
• Feature: Overhoal of web interface push panel, displaying hints according to the new capabilities and fixing several outstanding bugs and user interface annoyances
• Feature: New scheduled pushes system, allowing complex push rules based on variable conditions
• Feature: Generic "external writer" support. Anyone can now implement a writer for any custom protocol in any scripting/programming language of their choice. These are used by the push system (and DTSH header writing). Livepeer has been kind enough to provide a sample uploader that supports S3 and IPFS protocols
• Feature: Added FLAC file input and output support, FLAC file analyser
• Feature: WebRTC WHIP/WISH push input support and WHEP pull output support
• Feature: HLS input, TS input and EBML (MKV/WebM) input now all transmit an indication of header generation progress during header (re)generation. This indication is displayed in the default player if applicable
• Feature: When a VoD input shuts down unexpectedly, outputs will attempt to restart it before aborting now
• Feature: HLS input from remote sources has received significant speed-up improvements
• Rollback: LLHLS support was removed, and HLS output rolled back to the version we had in the 3.0 release. (This is a temporary measure while we work on improvements, due to too many reports of unstable streams in the new LLHLS output that was introduced in the 3.1 release)
• Improvement: Incoming pushes (over all protocols) are now accepted much faster than before
• Improvement: Tweaked log message verbosity levels to draw attention to the right things at the right times more effectively
• Improvement: VoD inputs now keep data buffered for 15 seconds instead of 15 loop iterations (loops were sometimes significantly slower than a second, causing too much buffering to occur)
• Improvement: We now match libav's RTMP receive window overflow behaviour
• Improvement: Web interface now has a new "General" tab that contains, most general settings
• Improvement: Supported codecs for MistIn* processes are now more consistently reported in the system capabilities (as well as inside -j outputs for each process)
• Improvement: Manually started MistProcLivepeer processes now have an extra commandline flag to boot their input stream and wait for boot-up to complete before starting transcoding (makes manually started VoD transcoding possible)
• Improvement: Fixed MistUtilRAX segfaulting rather than just erroring out when a memory page did not exist
• Improvement: Fixed/removed practically all compiler warnings
• Improvement: Added compatbility for QuickTime-style ISBMF files in MP4 input
• Improvement: MP4 analyser now calculates and prints simple 90-degree-increment rotations, correctly prints transformation matrices
• Improvement: Significant simplification (and speed-up) of MP4 input
• Improvement: Added dtsc_sizing test to verify correct sizing of internal memory structures

• Improvement: When building using Meson, now automatically pulls in all non-locally-installed dependencies and compiles them in a subdirectory
• Improvement: Added several dozen automated (unit) tests when building using Meson
• Improvement: Added per-track RTMP timestamp rollover handling (improves compatibility and stability with several RTMP implementations when receiving streams longer than ~4 hours)
• Improvement: TS-based push outputs now actively re-select newly available tracks mid-push if possible
• Improvement: Renamed MistInSRT and MistOutSRT to MistInSubRip and MistOutSubRip to prevent confusion between SubRip SRT and Haivision SRT (configuration will automatically migrate accordingly)
• Improvement: No longer send Content-Length header when a chunked reply is sent, which was breaking compatibility with some HTTP proxies (now forces a Range header instead, so progress display during download is still possible)
• Improvement: HLS inputs now store relative paths in DTSH files, to allow their re-use between local and remote accesses (if needed, DTSH headers will auto-regenerate)
• Improvement: VoD loading is now prioritized based on how many users want to watch a certain section of a file (rather than first-come-first-serve)
• Improvement: When buffering VoD data, if internal inconsistencies are detected, these are now reported in a more readable (and less spammy) way
• Improvement: VoD inputs now check requested file ranges 4 times per second rather than once per second (improves seek times for outputs)
• Improvement: Updated several internal players for the built-in Meta-Player, added support for selecting metadata tracks separately from the playback protocol
• Improvement: Added new bframes track selector, which matches all (video) tracks that contain B-frames
• Bugfix: TS SRT listening sockets now allow passing configurations as GET parameters

• Bugfix: Push outputs no longer get stuck waiting for requests that will never come when connecting to their corresponding input fails
• Bugfix: Fixed RTMP extended timestamp parsing
• Bugfix: RIST push outputs now allow setting RIST GET parameters separately from Mist GET parameters (dual-? syntax, same as other push outputs)
• Bugfix: Fixed forcetype and urlappend options in .html output
