OvenMediaLabs/OvenMediaEngine v0.20.5

on GitHub

[Compatibility]

• Compatible with dependencies installed via prerequisites.sh in version 0.19.0 or later.
• Compatible with the Server.xml configuration format used in version 0.12.6 or later.
• Compatible with Origin and Edge versions 0.21.0 or later.

[Added]

• Added an option to set the TimestampMode for RTMP/SRT/MPEG-TS push publishers.
• Added receive timeout support to the Transcode webhook.
• Added ConnectionTimeout and SendTimeout settings to the Push Publisher.
• Added maxWidth and maxHeight properties to the Track object.
• Added the Oven-Capabilities HTTP header (max_width=, max_height=) in WHIP.
• Added ExtraOptions video encoding settings for the x264 encoder.
• Added a resolution validity check to the H.264/H.265 parser.
• Added support for HLS subtitles.
• Added a FIRInterval setting to the WebRTC Provider.
• Added the <RtcpBasedTimestamp> option to the WebRTC Provider (default: false). This allows OME to start playback immediately for WHIP input without waiting for RTCP.
• Added the forwardData option to ScheduledChannel items (default: false). When set to true, data from the live input is forwarded through the ScheduledChannel.
• Added Transport-cc support to WebRTC Bandwidth Estimation, enabling more precise automatic switching in WebRTC ABR.
• Added a max_fps option to OvenCapabilities in WHIP and a max_fps field to Stream Info.

[Improved]

• Improved the wrap-around algorithm for the time value inside the TS container.
• Improved logs to show the Transcode webhook response time.
• Improved the Push Publisher to output detailed logs upon failure.
• Improved the logic to prevent duplicate encoder creation.
• Improved the automatic SkipFrames configuration algorithm.
• Improved the cleanup process for (LL-)HLS streams to be faster, regardless of the connection status.
• Improved performance by fixing the number of sessions when (LL-)HLS operates in Origin mode.
• Improved multi-audio input to allow selecting a track by index for Push when VariantName is duplicated.
• Improved multi-audio input to allow selecting a track by index for Record when VariantName is duplicated.
• Optimized transcoding performance by minimizing unnecessary memory copies.
• Improved RTMP encoder compatibility.
• Improved the accuracy of framerate and keyFrameInterval calculations.
• Reduced shutdown times that could previously take longer than expected.
• Improved compatibility between OME and WHIP simulcast in OBS 32.1.0.
• Improved LLHLS playback behavior in OME to address abnormal playback caused by compatibility issues with Shaka Player.

[Changed]

• Changed the default number of retries for the OVT Provider to 0.
• Moved the subtitle configuration from <Application><OutputProfiles><MediaOptions><Subtitles> to <Application><Subtitles>.
• Updated the GET Stream API so that outputs[] information is returned for streams pulled via OVT.
• Updated to support hardware acceleration (Transcoding, Speech-To-Text) with NVIDIA Driver 535+ and CUDA 12.0+.

[Fixed]

• Fixed an issue where the recorded file sometimes got corrupted when the stream ended.
• Fixed a crash that occurred when socket creation failed in the OVT Provider.
• Fixed an issue where receiving an unknown RTMP AMF message could cause a crash.
• Fixed an issue where the Timeout setting in AdmissionWebhooks was not working correctly.
• Fixed an issue where, when WHIP and LLHLS connected as a single session, the connection could be routed to an incorrect module.
• Fixed an issue where the OVT Publisher could crash due to malicious packets.
• Fixed an issue where a crash could occur due to invalid video metadata.
• Fixed an issue where a delayed Transcode webhook blocked other streams.
• Fixed a crash that occurred when the Transcode webhook response is returned as an array.
• Fixed an issue where the session was terminated if the DTS was not monotonically increasing during an RTMP Push.
• Fixed an issue where the DTS might not increase monotonically during event insertion via the API.
• Fixed an incorrect frame rate value in HLS/LL-HLS playlists when using SkipFrames.
• Fixed OVT to correctly synchronize the publicName, maxWidth, and maxHeight properties of media tracks.
• Fixed an issue where streams in the SRT Publisher might not be properly cleaned up.
• Fixed incorrect information display for tracks with reused encoders.
• Fixed an issue where OVT streams could miss network events.
• Fixed an issue where FairPlay playback could fail on iOS.
• Fixed an issue where restart requests failed for applications dynamically created via the API.
• Fixed an issue where the OVT Publisher's stream might not terminate completely when using OriginMapStore.
• Fixed an issue in LLHLS OriginMode where HTTP requests received immediately upon stream start could be missed.
• Fixed an issue where the AdmissionWebhooks opening event could be triggered twice when using E-RTMP.
• Fixed a default path issue in recording when FilePath is not specified.
• Fixed a recording failure caused by unsupported codecs.
• Fixed an issue where the closing event might not be delivered when using AdmissionWebhooks in certain environments.
• Fixed an issue where video encoded with an NVIDIA GPU became corrupted when the input resolution changed dynamically in WebRTC.
• Fixed an issue where the closing event was not delivered to AdmissionWebhooks when an ICE timeout occurred during WHIP streaming.
• Fixed an issue where real_ip (X-REAL-IP or X-FORWARDED-FOR) might not be delivered to AdmissionWebhooks during WHIP streaming in environments using an HTTP proxy.
• Fixed an issue where VP8 simulcast did not work correctly.
• Fixed an issue where the OVT Publisher attempted to register an RTSP URL again in Redis when it was already pulled from OriginMapStore.
• Fixed an intermittent crash when streams were rapidly created and deleted.
• Fixed an issue where SRT connections could fail under certain conditions.
• Fixed an issue where avgThroughputIn and avgThroughputOut in GET v1/stats/current/ could be overestimated.
• Fixed LLHLS so that at least one audio track is always configured with DEFAULT=YES and AUTOSELECT=YES.
• Fixed a potential crash when an AAC track with a corrupted audio sample rate (0) is received.
• Fixed an intermittent crash that occurred during simultaneous start/stop recording API requests.
• Fixed a memory leak on stream deletion when DelayBufferTimeMs was configured.
• Fixed a crash when the input stream ends during repeated push connection failures.
