v0.2.1
ac8141b
Changes
  • Intra frame period added as a command line option (-p).
  • Stdin support (give dash as input filename). (thanks @jeeb)
  • New unit test framework.
  • Replaced broken x86 cpuid asm implementation with a single implementation for both x86 and x64 using x264asm abstraction layer. We will be using x264asm for asm from now on.
  • Fixed Makefile to give correct build options for Mac and 32-bit Linux. (thanks @dirk and @rmustacc)
  • Fixed a small per frame memory leak.
  • Quality and bitrate improvements.
    • Merged a branch for changes related to intra 4x4 prediction block coding that isn't in use yet but fixed something resulting in improved quality.
    • Fixed bug in intra mode search resulting in increased intra quality.
    • Fixed CU split cost calculation, resulting in decreased bitrate.

We measured a cumulative average decrease in bitrate for a given quality (BD-rate) of 15% in LP configuration from v0.2.0 to v0.2.1. Although that was with a limited test set of just one 600 frame video.
