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 \ -loglevel error -stats -an -vcodec libx264 -b:v 3500k -preset:v slow -profile:v high -tune:v film \ -aspect 16:9 -vf scale=w=1280:h=720 -threads 1 -cpu-used 1 -f rawvideo -passlogfile \ video_out.mkv -pass 1 -y /dev/null

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:

I wish in your help. You are my last hope.

Why is your ffmpeg version so out of date?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.

Please explore at Linux-Sunxi IRC and wiki, hopefully developers in there able to help up
