v0.5.0

[0.5.0] - 2022-12-09

Added

• Access to all pylon image metadata
  • GrabResult
    • BlockID
    • ImageNumber
    • SkippedImages
    • OffsetX/Y
    • Camera Timestamp
  • Chunkdata
    • all enabled chunks are added as key/value GstStructure elements
  • for sample user code see the show_meta example
• Generation of includes, library and pkg-config files to access the GstMeta data of the plugin
• Camera properties accessible by integer based selectors are now accessible as gstreamer properties
  • some properties e.g. ActionGroupMask are selected by an integer index. Support for these properties is now integrated.

Changed

• Breaking change for width/height fixation:
  • old: prefer min(1080P, camera.max)
  • new: prefer current camera value after user-set and pfs-file
• Startup time on some camera models extended up to ~5s
  • This is a side effect of the fixes to properly capture the absolute min/max values of a property.
  • The first gst-inspect-1.0 after compilation/installation will block twice as long.
  • A caching infrastructure to skip this time on subsequent usages of pylonsrc is scheduled for the next release.

Fixed

• Properties have now proper flags to allow changing in PLAYING state if valid for pylon.
• Plugin uses only a single 'pylonsrc' debug channel (Fixes #22)
  • usage of 'default' and 'pylonsrc' channel was root cause of stability issues with extensive logging
• Detect the absolute min/max values of properties
  • the feature limits of GenICam based cameras can change depending on the operating point. The plugin now explores the min/max values possible with the current device.
• Allow generic introspection of plugin properties ( Fixes #18)
  • internal restructuring of property type system
  • for sample user code see the list_properties example
• Update readme to cover exact steps to build the plugin (Fixes #23, #19, #20)
• Upstream gstreamer fix to properly detect typos in gst-launch-1.0 pipeline definitions !2908
  • Fix is available in gstreamer >= 1.21
