Media Communications Mesh 25.03 release
1. New Features
1.1 MCM Control Plane - Media Proxy side - Implemented various features and improvements for the Media Proxy side of the MCM Control Plane, including RDMA testing, API updates, and integration of multipoint groups
- Updated dependencies and created directories for test scenarios
- Implemented RDMA with TCP provider testing and integration
- Updated FFmpeg plugin and SDK API to support JSON configuration
- Developed unit tests and fixed high impact issues
- Implemented business logic for multipoint groups and system metrics
1.2 MCM Data Plane - Overhauled the existing architecture of the Media Communications Mesh project to meet customer expectations and deliver a production-ready solution. This included designing and implementing necessary modifications to enhance performance, reliability, scalability, and usability
- Implemented new MCM SDK API and updated documentation
- Fixed RDMA endpoint creation, laid foundation to using Verbs provider
- Updated sample applications and integrated API changes
1.3 RDMA implementation - Enhanced the RDMA (Remote Direct Memory Access) over TCP provider implementation within the Media Communications Mesh project to achieve a target bandwidth of approximately 94 Gb/s on E810 NIC
- Investigated optimizations for RDMA and created unit tests
- Conducted performance testing and benchmarking
- Developed documentation and best practices for deploying RDMA
- In the next release RDMA will be using Verbs provider with RoCE
Media Communications Mesh 24.09 release
Release notes for 24.09
1. New Features:
1.1 Support for RDMA data transfer between media proxies
- Added RDMA implementation and rdma_args in payload_args; Created script to prepare environment for RDMA (#187)
- Build and install libfabric, libxdp and libbpf (#188) and updated codeql.yml, coverity.yml to include changes from ubuntu build: libfabric, libxdp and libbpf; Added LIBFABRIC_DIR to Media_Proxy Dockerfile
- Updated README with libfabric dependencies
- Added test-rdma.sh with RDMA functional tests
1.2 FFmpeg plugin
- Added FFmpeg 7.0 support (#182) and set it as a default version (with a possibility to run 6.1)
- Add MTL audio ptime options and compatibility check in FFmpeg plugin
- Added FFmpeg MCM audio plugin with documentation and configuration arguments - number of audio channels (1, 2, etc.), sample rate (44.1, 48, or 96 kHz), MTL PCM format (16-bit or 24-bit Big Endian), MTL packet time
1.3 Sample app
- Added throughput printing in sample apps
1.4 AF_XDP/eBPF
- Run basic implementation of AF_XDP/eBPF (#180) using mtl native functions and MtlManager: The enablement of
native_af_xdpfor interfaces used in media-proxy workloads required minor impact changes in Dockerfile build sequence as well as adjustments to proxy_context
1.5 Containers (Docker)
- Dockerfile size shrink to 265MB + Mtl-Manager (#168) added by default to the container
- Updates to Dockerfile, packages: autoconf, automake, autotools-dev, libtool
1.6 Documentation and tests
- Updated readme with supported audio argument options (#208)
- Update documentation on audio ptime options
- Added sequence diagrams of MCM FFmpeg plugin
- Added option to conditionally build unit tests: To disable compilation of unit tests one can invoke "BUILD_UNIT_TESTS=OFF ./build.sh"
- Parameters guide and kubernetes readme modifications (#169)
- Added Sphinx documentation and Github action automation to build it
- Added sketch for unit tests
- Update licenses and added copyright notices
1.7 Other
- Added memif_buffer_alloc_timeout()
2. Changes to Existing Features:
- Changed how threads are cancelled: Resources may not have been deallocated at all or deallocated while the thread was still running
- Not printing error if pthread_join() returns ESRCH: ESRCH means the thread has already exited
- Removed unnecessary pacing from sender_app
- MCM st22 fix to media_proxy segfault: added fix for media_proxy exit with segfault
- Improved pthread_cancel() err handling: pthread_cancel can only return ESRCH or success. ESRCH means that the thread is not running, which is not an error for us.
- Fixed error handling
- Changed audio buffer size in memif protocol mode
- Reworked PCM16/24 support (+FFmpeg plugin)
- Cleanup ffmpeg plugin build scripts (#183): JPEG XS is not required as direct ffmpeg-plugin, but used internally by MTL (kahawai.json), inside media-proxy
- Memif native library based functional tests (#177): Functional tests for inter-process communication have been added, as an extension to existing tests
- Ext_frame: Corrupt frame output fix (#174): Frame size corrected, check for transport and frame size added, MTL memory alignment added
- Fixes to test.sh to include custom interface names
- Remove metadata from sent buffer (#173): Video data was overwritten with metadata, which resulted in not enough data being sent
- Styling and indentation fixes in documentation
- Updated udp_impl.c and fix the ssize_t overflow issue.
- Updated CMakeLists.txt append "-fPIC" flag
- Full code for library version control and load from tag
- Libraries libraisr and libmcm_dp use position code independent properties from now on.
- Added scripting for version from git parsing (exactly from tag) or if this fails default one is being set.
- Changed default patch actions for ffmpeg-plugin
- Dockerfiles adjustments to meet Trivy requirements: ports exposed, default user, entrypoint, other minor
- Various dependency bumps from Dependabot suggestions
3. Fixed Issues:
| Title | Component | Description |
|---|---|---|
| Media Proxy crashes with segfault when receiving 1st frame in recver_app | Media Proxy | Fixed |
| Input and output files differ in size when sent between sample apps in ST20 mode | Sample apps | Fixed |
| Segmentation Fault crash of Media Proxy application (for not aligned configuration pixel format with a stream format) | Media Proxy | Fixed |
| Media Proxy on Rx side exits unexpectedly when user stops Tx FFmpeg | Media Proxy | Fixed |
| Frames sent with ext_frame feature are corrupted | Media Communications Mesh | Fixed |
| Media Proxy crashes with Segfault when closing st22 session | Media Proxy | Fixed |

Media Communications Mesh 24.06 release
New Features
- Media Communications Mesh FFmpeg plugin
- Video Input/output plugin for FFmpeg – video processing pipeline framework.
- Single or multiple instances of FFmpeg with Media Communications Mesh Plugin connect to selected Media Proxy instance.
- Supported video pixel formats:
- YUV 422, 8bit packed
- RGB 8 bit
- NV12 – YUV 420 planar 8 bit
- YUV 444 planar, 10 bit, little endian
- YUV 422 planar, 10 bit, little endian
- No support for audio streams
- Enablement of PTP Time synchronization to Media Communications Mesh.
This feature uses Media Transport Library PTP Time synchronization feature. - Added support to Media Proxy/SDK for changing input and output streams Payload ID.
Payload IDs beside of having defined default values (according to RFC or SMPTE specification) are passed as parameters for each stream. - Added support to Media Proxy/SDK for receiving video stream from multicast group/publishing video stream to a multicast group
Added parameter to stream configuration allowing to pass multicast group IP address.
Changes to Existing Features
- Modified docker file to decrease docker image minimal runtime size.
