v3.0.0

Release notes (v3.0 release):

Bug fixes:

• Decoding:

  • Fixed a crash with AccessViolationException in the video frame decoding method (#31)
  • Fixed a crash when disposing MediaOutput.

• Encoding:

  • Fixed the invalid DTS error when disposing H.264/H.265 encoder.

New features:

• Decoding:

  • Added the IsVariableFrameRate and IsFrameCountProvidedByContainer properties to the StreamInfo class.

• Encoding:

  • Added CRF and preset options in the VideoEncoderSettings class. (for H.264/H.265 codec)
  • Added an option to set metadata in container using the new ContainerMetadata class. (.UseMetadata(...) method in MediaBuilder)
  • Added an option to apply custom flags when creating a container (.UseFormatOption(key,value) method in MediaBuilder)
  • Added an option to specify a container format independently from target file name (using MediaBuilder.CreateContainer(path,format) overload)
  • Added option to set PTS for a new frame. (#23)
  • Added UYVY422 format support (#26)

Other improvements

• Redesigned FFmpeg loader and improve exception messages.
• Created a new class for multimedia metadata.
• Merged VideoPixelFormat and ImagePixelFormat format
• Improved frame decoding performance.
• Improved FrameCount accuracy.
• Created a new VideoCodec enum which only contains supported codecs (instead of FFmpeg.AutoGen.AVCodecID)
• Video encoder throws an exception when attempt to use the x264 encoder with LGPL FFmpeg binaries.

Migration guide

• Use FFmpegLoader instead of MediaToolkit.
• Use MediaBuilder.CreateContainer(...) instead of new MediaBuilder(...).
• Use ImagePixelFormat instead of VideoPixelFormat.
• Use the VideoCodec enum instead of FFmpeg.AutoGen.AVCodecID.

FFMediaToolkit-v2.2.1

• Fixed a possible crash in the MediaToolkit.LogVerbosity property (when setting the log level before specifying the FFmpeg directory).

FFMediaToolkit-v2.2.0

• Added a FFmpeg log verbosity level setting (#19 )
