MC Live Encoder 3.5 Release Notes

[Olga Bulava]

New Features and Major Improvements in MainConcept Live Encoder V3.5

• It is now possible to independently encode each AAC audio channel.
  
• HLS output now supports multi-audio tracks.
  
• Added support for:
  
• MPEG-2 video encoding and DVB presets
  
• MPEG audio encoding
  
• Multi-track audio for source streams
  
• Input source audio such as AC-3 can now be passed unmodified through the encoder to an output stream.
  
• Improved quality of low resolution AVC/H.264 encodings at scene changes.
  
• Improved user experience when adding new sources.
  
• Rotated log files are now automatically compressed to save disk space.
  

Known Issues in MainConcept Live Encoder V3.5

• [NDE-151] Start/stop encoding causes the encoder to behave unpredictably when no disk space is available and, as a result, may not produce any output signal
  
• [NDE-261/NDE-280] When using a two-second segment size for HLS creation with either AVC/H.264 or HEVC/H.265 hardware or software encoding, the peak bitrate sometimes exceeds the bandwidth specified in the HLS master playlist by more than 20%. There is no problem when using 4 or 6 second segment sizes
  
• [NDE-409] Occasional frame drops when doing HEVC 8K 60p 10-bit liveencoding on Linux.
  
• [NDE-462] It is currently not possible to insert logos with a bit depth of 8-bit or less.
  
• [NDE-524] There is a memory leak after stopping streaming of LCEVC streams on Linux. This memory is reused if streaming is restarted.
  
• [B-83199] Closed Captions information is not written into MPEG-DASH manifest files. This can be corrected by a separate packaging tool.
