Raw

0.14.0

  • Audio support
  • New demo for extracting audio from a video to a mp3
  • New demo with both video and audio using sinusoidal audio waves

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.
