This is the complete list that’s outputted by ffmpeg when running ffmpeg -h full. | |
usage: ffmpeg [options] [[infile options] -i infile]… {[outfile options] outfile}… | |
Getting help: | |
-h — print basic options | |
-h long — print more options | |
-h full — print all options (including all format and codec specific options, very long) |

First of all: YUV pixel formats and Recommended 8-Bit YUV Formats for Video Rendering. Chromium's source code contains good documentation about those formats too: chromium/src/media/base/video_types.h and chromium/src/media/base/video_frame.cc (search for RequiresEvenSizeAllocation()
, NumPlanes()
and those kinds of functions).
You can think of an image as a superposition of several planes (or layers in a more natural language). YUV formats have three planes: Y
, U
, and V
.
Y
is the luma plane, and can be seen as the image as grayscale. U
and V
are reffered to as the chroma planes, which are basically the colours. All the YUV formats have these three planes, and differ by the different orderings of them.
