This gist shows how to create a GIF screencast using only free OS X tools: QuickTime, ffmpeg, and gifsicle.
To capture the video (filesize: 19MB), using the free "QuickTime Player" application:

Here’s how to make animations like this one. It requires intermediate Unix command-line knowledge, to install some tools and to debug if they don’t work. You’ll need these utilities:
curl
(or you can translate to wget
)convert
and montage
, part of ImageMagickffmpeg
, plus whatever codecsparallel
, for iteration that’s nicer than shell for loops or xargs
zsh
for leading 0s in numerical ranges to workFor users who prefer working with a command line or need to access advanced encoding settings for Hap the popular FFmpeg library can be used to work with Hap movies.
If this is your first time using FFmpeg you may need to install it on your system, or compile it from source. In either case be sure that Snappy is enabled as part of the binary. If you already have FFmpeg on your system with Snappy enabled, you can skip this step.
You can check that your version of FFmpeg can encode Hap using
ffmpeg -encoders | grep hap
float map(float value, float min1, float max1, float min2, float max2) { | |
return min2 + (value - min1) * (max2 - min2) / (max1 - min1); | |
} |
Goal: Emulate a Raspberry Pi with QEMU in order to run the Raspbian O/S (based on Debian Linux).
The current setup is not ideal. For one thing, the maximum RAM allowed using the "versatile-pb" firmware is 256 Mb. In addition, only the most basic peripherals, a keyboard and mouse, are supported.
A number of articles have been written on this topic. Most are outdated, and the few recent ones are missing key information.
