ffmpeg for x264 encoding - klode - 05-04-2019 I'm working on use my Pine64 RevB (2016) with 2Gb RAM, and armbian distro installed, for x264 encodings. I'm using this command: Code: ffmpeg -i video_in.mkv \ using the 2-pass encoding method. In this case, I got 2.7 fps on analysis. If I use: Code: -threads 3 -cpu-used 1 i got about 4.5 fps. I've found another ffmpeg compiled for AllWinner H3 processor. May I use this? The configuration of my ffmpeg is: Code: ffmpeg version 2.8.15-0ubuntu0.16.04.1 Copyright (c) 2000-2018 the FFmpeg developers I wish in your help. You are my last hope. RE: ffmpeg for x264 encoding - GRATS - 06-06-2019 Why is your ffmpeg version so out of date? The new syntax for everything like your "-vcodec" would be "-c:v" libx264 -c:v -c:a -b:v -b:a etc Are you trying to get higher fps? change the "slow" preset to "ultrafast" ultrafast, superfast, veryfast, faster, fast, medium (default), slow, veryslow I only use medium and slow on x86 with 8 cores.. even if I'm doing real time encoding on 8 cores I'll use veryfast normally.
