v2024.0

Changelog

[2024.0] [libnopegl 0.11.0] - 2024-02-02

Added

• ngl.SceneCfg now includes the backend capabilities
• %s_coord_matrix uniform is now exposed for 2D array and 3D textures
• ngl_get_backend() function to retrieve the backend information associated
  with a configured nope.gl context
• ngl-diff can now set and change the input files from the GUI. While still
  supported, passing them through the command line is not mandatory anymore
• ngl_scene_ref and ngl_scene_unrefp functions to respectively increment and
  decrement the reference counter of a scene
• GaussianBlur node to apply a post processing gaussian blur effect to a
  scene with a resolution dependent bluriness parameter. The bluriness
  parameter can provide a gaussian blur effect with a radius up to 126 pixels
• FastGaussianBlur node to apply a post processing gaussian blur effect to a
  scene that is suitable for real time rendering on mobile devices as well as
  providing a resolution independent blurriness parameter
• forward_transforms parameter to the Texture and RenderToTexture nodes
  to enable forwarding of the camera/model transformations
• Selector filter to select colors according to their lightness, chroma or hue
• AnimKeyFrame* nodes can now be reused at a different time using the
  Animated*.time_offset parameter
• TextEffect.end_time now automatically uses the scene duration when
  unspecified

Fixed

• Moving the split position in ngl-diff
• Crash in the hwconv module when direct rendering is not possible/enabled
• Export to output files containing spaces in their path on Windows
• Crash when decoding videos on Android with the OpenGLES backend

Changed

• ngl.get_backends() and ngl.probe_backends() were mistakenly inverted in
  v2023.2, this is changed back in this release
• SceneCfg and SceneInfo now use the Backend enum instead of a string
• ngl_configure() does not update the backend field from the user
  configuration anymore and the config argument is now const. Users must now
  use ngl_get_backend() to get the underlying backend information
• ngl_scene_init_from_node() has been replaced with
  ngl_scene_init() with the associated ngl_scene_params structure
• the ngl_scene structure is now private; its parameters can now be obtained
  using ngl_scene_get_params()
• the Texture and RenderToTexture nodes no longer forward the camera/model
  transformations by default

Removed

• %s_dimensions uniform for 2D array and 3D images/textures, users must use
  textureSize()/imageSize() instead (%s_dimensions is still available for 2D
  textures)

Removed

• ngl_scene_freep function; use ngl_scene_unrefp instead
