Two years later, I'm getting up this topic to get new tips if anyone has it
Is there a difference (quality, speed) between FFmpeg as decoder+encoder versus AviSynth/VapourSynth (with plugins ?) as decoder + x265 as encoder ? Without any filters, just serve the source as it. Thanks ! |

Technically, using FFMpeg would allow you to skip the indexing part and serve the decoded frames on the fly. That being said, I've never used FFMpeg to decode and encode anything directly. Also you would have no control over which build of libx265 is being used and which assembly optimizations have been used in the build (SSE, SSE2, SSSE3, SSE4.1, SSE4.2, AVX, AVX2, AVX512). On top of that, I don't trust FFMpeg 'cause I don't know if it's actually turning on some filters under the hood, so my suggestion is to stick with Avisynth + x265 |

Avisynth/vs has other more important benefits than this compared to ffmpeg. If you need a lot of filters then nothing can beat avs/vs. ffmpge allows you to control builds- it always says which x264/5 build it's using and you can aways build ffmpeg with specific x264/5 version if needed. If anything I'm not that confident with avs/vs input filters, except avi (plenty issues with frame accuracy, missing frames etc). For me it's avs/vs weakest part (ffms2 is far from been very reliable). Last edited by kolak; 22nd November 2021 at 17:11. |
