Yes, I think that must be it. While writing a reply to the previous poster (I use the GUI iFFMpeg) I thought I would examine the output from the last working build (end of Nov) with one of the blow out builds.
in the log output for the good (Nov) build I have... x265 [info]: HEVC encoder version 2.6+2-32e6f04b8713 x265 [info]: build info [Mac OS X][clang 8.0.0][64 bit] 10bit x265 [info]: using cpu capabilities: MMX2 SSE2Fast LZCNT SSSE3 SSE4.2 AVX FMA3 BMI2 AVX2 Whereas in the post DEC builds (which blow out in time) I have.... x265 [info]: HEVC encoder version 2.6+14-f09f3b4a2115 x265 [info]: build info [Mac OS X][clang 8.0.0][64 bit][noasm] 10bit x265 [info]: using cpu capabilities: none! Which I guess would explain the slower times and also why the builds are smaller. Guess I will need to wait until the HW acceleration is enabled again. > On 18 Dec 2017, at 12:14 pm, Christopher Snowhill <[email protected]> wrote: > > >> On Dec 17, 2017, at 4:46 PM, James Hale <[email protected]> wrote: >> >> I have been using snapshot builds for the Mac of ffmpeg for the last year >> and have noticed a dramatic change since build 89381 (from the beginning of >> Dec.)
