News - Orc 0.4.41 bug-fix release

The GStreamer team is pleased to announce another release of liborc, the Optimized Inner Loop Runtime Compiler, which is used for SIMD acceleration in GStreamer plugins such as audioconvert, audiomixer, compositor, videoscale, and videoconvert, to name just a few.

This is a bug-fix release.

Highlights:

  • orccodemem: Don't modify the process umask, which caused race conditions with other threads
  • Require glibc >= 2.07
  • x86: various SSE and MMX fixes
  • avx: Fix sqrtps encoding causing an illegal instruction crash
  • Hide internal symbols from ABI and do not install internal headers
  • Rename backend to target, including `orc-backend` meson option and `ORC_BACKEND` environment variable
  • Testsuite, tools: Disambiguate OrcProgram naming conventions
  • Build: Fix `_clear_cache` call for Clang and error out on implicit function declarations
  • opcodes: Use MIN instead of CLAMP for known unsigned values to fix compiler warnings
  • ci improvements: Upload the generated .S and .bin and include Windows artifacts
  • Spelling fix in debug log message

What is GStreamer?

GStreamer is a library for constructing graphs of media-handling components. The applications it supports range from simple Ogg/Vorbis playback, audio/video streaming to complex audio (mixing) and video (non-linear editing) processing.

Applications can take advantage of advances in codec and filter technology transparently. Developers can add new codecs and filters by writing a simple plugin with a clean, generic interface. Read more ...

GStreamer is released under the LGPL. The 1.x series is API and ABI stable and supersedes the previous stable 0.10 series. Both can be installed in parallel.
