Ffmpeg gif quality
3 septembre 2018, par fcbergMy application extracts images from a video file and generates a gif using the following command :
ffmpeg -f image2 -framerate 10 -i 1535983531_%03d.jpg
By looking at the images used to generate the gif, the quality is good. Example below.
However, the generated gif has poor quality and it’s pixelated. Example below.

How do I improve it to generate a gif with better quality ?

How to import fluent-ffmpeg in aws lamdba ?
3 octobre 2019, par FookI’m trying to use fluent-ffmpeg in AWS Lambda, but cannot get it setup correctly. At the top of my index.js :
import ffmpeg from "fluent-ffmpeg";
But it is always undefined.
ffmpeg === undefined
.I’m using Serverless and have ffmpeg included as a layer.
serverless.yaml
functions:
createGifFromVideo:
handler: src/services/createGifFromVideo/index.handler
layers:
- { Ref: FfmpegLambdaLayer }
events:
- sns: arn:aws:sns:us-east-1:${self:custom.accountId}:NewVideoPostContentTopic-${self:provider.stage}
layers:
ffmpeg:
path: src/layerspackage.json
{
"name": "createGifFromVideo",
"version": "1.0.0",
"main": "index.js",
"license": "MIT",
"private": true,
"dependencies": {
"fluent-ffmpeg": "^2.1.2"
}
}The uploaded lambda seems to be constructed correctly from what I can tell. Webpack builds the file with fluent-ffmpeg merged in and it is linked to the ffmpeg layer.
I can load other packages. It’s just fluent-ffmpeg that comes back
undefined
.From the docs it mentions passing
FFMPEG_PATH
andFFPROBE_PATH
as environment variables. Are these necessary with a layer ?I would be grateful to see a configuration that works.
