I was able to get Ruby 2.5.1 building on M1 by following two of the steps in that GH issue...

rbenv/ruby-build#1691 (comment) rbenv/ruby-build#1691 (comment)

I installed readline and openssl with standard brew install.

brew install readline
brew install openssl

These are a few quick easy ffmpeg command lines that can be used to make oft-used video formats. I use them a lot so I wrote them down in a txt file but I converted it to markdown to upload here and access on all my pcs.

Feel free to use 'em. I've gathered them through superuser posts, wiki trawls, and personal experience.

General notes

• Add -movflags faststart to make mp4 files have their headers at the beginning of the file, allowing them to be streamed (i.e. played even if only part of the file is downloaded).
• mp4 container supports mp3 files, so if libfdk_aac isnt available (it's the only good aac enc) use libmp3lame.
• For mp4 files, use -preset X to use mp4 enc presets, like slow or superfast. (veryfast or fast is ok)
• c:v refers to the video codec used (codec: video). Likewise, c:a is audio. If you're using -map or something, this can be extended (-c:a:0: codec: audio: stream 0)

Encoding high-quality HEVC content with FFmpeg - based NVENC encoder on supported hardware:

If you've built ffmpeg as instructed here on Linux and the ffmpeg binary is in your path, you can do fast HEVC encodes as shown below, using NVIDIA's NPP's libraries to vastly speed up the process.

Now, to do a simple NVENC encode in 1080p, (that will even work for Maxwell Gen 2 (GM200x) series), start with:

ffmpeg  -i <inputfile>  \
-filter:v hwupload_cuda,scale_npp=w=1920:h=1080:format=nv12:interp_algo=lanczos,hwdownload \

-c:v hevc_nvenc -profile main -preset slow -rc vbr_hq \
