0.13.0

• Support webcams on Linux

0.12.2.2

• Fix a video playback framerate issue in the vplay demo (@gelisam)

0.12.2

• Better support for ffmpeg-3.4.2 API changes

0.12.1

• Bump base upper bound
• Rewritten Travis-CI support for GHC 8.02, 8.2.2, and 8.4.2

0.12.0

• Refactoring to better interoperate with SDL2
• SDL2 video player demo executable

[Thanks to Vladimir Pankov!]

0.11.1

• Use Control.Monad.Except instead of the deprecated Control.Monad.Error (Issue reported by Alexander / @AleXoundOS)

0.11.0

• Query stream duration (Matthias Treydte)
• Initial support for verbosity control; defaults to quiet
  • Can be changed with the new setLogLevel function

0.10. 0

• Fix encoder bug that created a single black frame at the start of every video (Jonathan Daugherty)

0.9.0

• Add support for camera input (Thomas M. DuBuisson)

  • Try it: build the demo executable (cabal configure -fBuildDemo) and run cabal run demo -- cam to record 10s of video from a connected camera to an output file camera.mov.

• Extract frame time stamps from the video stream rather than the codec context (hat tip to Jaro Reinders)

0.8.2

• Added probe features

0.8.1

• Update raster demo to use new JuicyPixels-3.2 API

0.8

• Update to transformers-0.4.1 and mtl-2.2.1

  • Changed decode-related types to accomodate deprecation of the Error class. This means that if you want to initialize decoders in your own transformer stack that has a MonadError instance, you will need to use the variants with names suffixed by a "T" (for transformer).

• Update to ffmpeg 2.3

  • Address deprecation warning

    Using AVStream.codec.time_base as a timebase hint to the muxer is deprecated. Set AVStream.time_base instead.

  • Address "non-strictly-monotonic PTS" warning

• Rasterific bump

  • Rasterific exports its own linear algebra types as of 0.3

0.7.1

• Bumped transformers dependency

  Note: The use of mtl still triggers deprecation warnings from transformers.

• Fixed bug with changing source pixel format from RGB during encoding.

• Added BGRA pixel format

0.7

• Simplified top-level API to focus on JuicyPixels-based interface

0.6

• Cleaned the API of detritus. Use the image* functions.

0.5

• Juiced the Encode and Decode APIs.

  Using imageWriter and imageReader provides a degree of pixel format polymorphism based on JuicyPixels pixel types.

0.4

• Fixed corrupted output of palettized animated GIFs.

• Added palettization options

  • Using avPixFmtRgb8 results in a small file

  • Using the default pixel format (avPixFmtPal8) results in a good-looking, fairly large file thanks to JuicyPixels's palettize function.

  • Setting the epPreset field of the EncodingParams value passed to frameWriter to "dither" results in an even prettier, even larger GIF file (again, thanks to JuicyPixels's palettize function).

  • See the demo/Raster.hs for examples.

0.3.1

• Automatically palettize RGB24 to RGB8 for GIF output.

• Add a Rasterific demo program that records an animation.

0.3

• Support for GIF encoding (and other palletized formats).

0.2

• Separate Scaler module and friendly libswscaler interface.

• Generalized toJuicy conversion.

• Added demo program.

0.1

• Basic h264 encoding and decoding.
