If you have problem drawing images in cavas you might want to look at this options:

Web framework

As 05/26/22, I am having problems sending the raw data of images from rust to js. Tauri developers are saying that the IPC will improve by Tauri v2. Until then I might use a framework to send the data.

Check this discussion

  • Rocket
  • Axum (recommneded and use by the developer)

Video decoder

command to get an specific frame from video:

$ .\ffmpeg.exe -i .\SC_07.mov -vf "select=eq(n\,10)" -f image2pipe -vframes 1 -

$ .\ffmpeg.exe -i .\SC_07.mov -vf "select=eq(n\,10)" -f rawvideo -pix_fmt rgba -vframes 1 -

-i input file. vf filter specific frame (frame 10 in this case) -f format to output. image2pipe this allows me to send image through pipes instead of saving it into a file. rawvideo output the raw info of the image. - this is the output

-i .\SC_07.mov -vf "select=eq(n,10)" -f rawvideo -pix_fmt rgba -vframes 1 -

Some Notes

Install the app npm dependencies

cd into the project and type:

npm install

Start a new Tauri project

# Create a new tauri app
$ npx create-tauri-app

# Start tauri development window
$ npm run tauri dev

# Build an Tauri app
$ npm run tauri build

Install Tailwind on my Svelte project

https://css-tricks.com/how-to-use-tailwind-on-a-svelte-site/

$ npm install -D tailwindcss postcss autoprefixer svelte-preprocess
$ npx tailwindcss init tailwind.config.js

tailwind.config.js

module.exports = {
    //The content section is where you configure the paths to all 
    // files that contain Tailwind class names.
    content: ['./src/**/*.{html,js,svelte,ts}'],
    theme: {
        extend: {},
    },
    plugins: [],
}

rollup.config.js

import sveltePreprocess from "svelte-preprocess";

plugins: [
		svelte({
			preprocess: sveltePreprocess({
				sourceMap: !production,
				postcss: {
				  plugins: [
				   require("tailwindcss"), 
				   require("autoprefixer"),
				  ],
				},
			}),

How I compiled ffmpeg

On MacOS

$ git clone https://git.ffmpeg.org/ffmpeg.git ffmpeg
$ brew install fdk-aac

$ ./configure  --prefix=/usr/local --disable-gpl --disable-nonfree --enable-libass --enable-libfdk-aac --enable-libfreetype --enable-libmp3lame --enable-libtheora --enable-libvorbis --enable-libvpx --disable-libx264 --disable-libx265 --enable-libopus --disable-libxvid --disable-chromaprint --enable-libopenjpeg --enable-libaom --extra-ldflags=-L/usr/local/lib --samples=fate-suite/

# MacOS - v02
./configure --cc=/usr/bin/clang --prefix=/opt/ffmpeg --extra-version=viewfx --enable-static --disable-shared --arch=x86_64 --disable-debug --disable-doc --disable-x86asm --disable-gpl --enable-version3 --disable-libx264 --pkg-config-flags=--static --disable-ffplay --disable-libxcb --disable-sdl2 --disable-xlib

# Check more options here -> https://github.com/FFmpeg/FFmpeg/blob/master/configure

$ make

On Win10

For now lets just use https://github.com/BtbN/FFmpeg-Builds/releases until I figure out how to build it on windows Use the one called ffmpeg-master-[VER]-win64-lgpl

$ pacman -S make
$ pacman -S diffutils
$ pacman -S yasm


$ git clone https://git.ffmpeg.org/ffmpeg.git ffmpeg
