The text says "y is the number of changes of chroma samples between the first and seconds rows of a pixels."

But isn't it more accurate to say:

"y is the number of changes of chroma samples between the first and last rows of a pixels."

If not, I still don't understand how chroma subsampling is used!

Hi, I noticed this line of code in README.md

printf("\tCodec %s ID %d bit_rate %lld", pLocalCodec->long_name, pLocalCodec->id, pCodecParameters->bit_rate);

in which pLocalCodec is not declared in the article before used which might cause confusion in my view. Digging into the c code, I found this line.

It appears that the documentation is not being built or installed by the
cmake build; the autotools build builds and installs the documentation
by default unless configured with --disable-doc.

Your default levels for ZSTD seem a little wonky:

• TURBO: ZSTD is missing, it should be -5 | --fast=5 (the fastest level currently available). This should push it into LZ4 territory.
• EFFICIENT should probably include 3, ZSTD's default level.
• OPTIMAL (meaning best trade off?) should probably be 20, as 22 balloons memory usa

According to https://en.wikipedia.org/wiki/AV1#Profiles
High profile (--profile 1) supports 4:2:0, but when I use 8bit with profile 1 I get:

Profile 1 requires 4:4:4 color format

High profile (--profile 1) supports 4:2:0, but when I use 8bit with profile 1 I get:

Profile 1 requires 4:4:4 color format

Professional profile (--profile 2) supports 4:2:0, but when I use 8bit with profile

Description

This goal is to make it easy for cross OS development with Linux by containerizing the dependencies for each OS in its own Docker image.

The runtime:

• Windows: https://www.winehq.org/
• Darwin: https://www.darlinghq.org/

#Now application store the recorded videos in the same source folder. The task is to store the video folder in $HOME/Videos/RecordedVideos/ [Linux folder structure]

/$HOME/Videos/RecordedVideos/ [store videos here]

Note: Create a new folder or check for the existing folder in the video folder path.
