What does 0 and 1 represents in ffmpeg?

[Anonymous543]

I seen in some video CABAC=1

And other video CABAC=0

What this 1 and 0 represents?

--no-cabac (x264)
-coder 0 (FFmpeg)
CABAC is the default entropy encoder used by x264. Though somewhat slower on both the decoding and encoding end, it offers 10-15% improved compression on live-action sources and considerably higher improvements on animated sources, especially at low bitrates. It is also required for the use of trellis quantization. Disabling CABAC may somewhat improve decoding performance, especially at high bitrates. CABAC is not allowed in Baseline Profile. Recommended default: -coder 1 (CABAC enabled)

So 1 means enabled and
0 means disabled?

boolean can be '1' or 'true' or 'on' and '0' can be 'false' or 'off' = btw - ffmpeg sometimes allow to use '-1' so this mean auto or default
