Making colour of MP4 video consistent in Chrome
21 septembre 2021, par OneWorldI see a difference in the colour of a video between different machines using different browsers. I was wondering what the cause of the difference is ?


I use FFMPEG to create the video. I sent the video to three different people with slightly different machines, and slightly different Chrome versions, to try and see where the differences are.


The FFMPEG output from the video is as follows :-

From the same UAT rendered Video, with screenshots taken in Chrome from person 1, person 2, person 3, and person 4, and using GIMP colour picker on my machine from the screenshots, the results for red, and yellow are as follows.


Person 1:- #A83833 and #FFCB2E Chrome Version 92.0.4515.131 (Official Build) (64-bit)
Person 2:- #AB3334 and #FFCA38 Chrome Version 92.0.4515.107


(Note : these colours Match / are very close to the original).


Both these machines above are 64 bit Ubuntu machines, using Ubuntu 18.04.5 LTS
We both use the gnome screenshot tool in Ubuntu to take the screenshot, which creates an 8bit PNG.


Person 3:- #B14039 and #FED303 Chrome Version 93.0.4577.63 (Official Build) (x86_64)
Person 4:- #B2403A and #FFD201 Chrome Version 92.0.4515.159 (Official Build) (x86_64)


Mac screenshots are taken using cmd shift 4, and generate an 8bit PNG file.


Person 3 Machine Spec :-
Machine :- Macbook Pro (2019)
OS : macOS Big Sur Version 11.5.2
Processor :- 2.6Ghz Intel Core i7 processor. 32bit architecture (typing arch in her tty terminal returns i386).
Graphics :- Intel UHD Graphics 630 1536


Person 4 Machine Spec :-
Machine :- Macbook Pro (Retina, 2015)
OS :- MacOS Mojave, Version 10.14.6
Processor :- 2.5GHz, Intel Core i7
Graphics :- AMD Radeon R9, M370X 2 GB Intel Iris Pro 1536 MB

Any suggestions anyone has to make these colours consistent would be much appreciated. Would love to know why it happens also ? If anyone can explain ?

Convert mp4/mov/... to mp4 with fluent-ffmpeg
13 octobre 2023, par Sam LeursI have a lambda function which reads a video from s3, converts it with fluent-ffmpeg and streams the video back to (another bucket in) s3.


This is the code so far :


ffmpeg()
 .input(readstream.Body)
 .format('mp4')
 .addOutputOption("-preset veryfast")
 .addOutputOption("-movflags frag_keyframe+empty_moov")
 .addOutputOption("-crf 28")
 .output(writestream, { end: true })
 .on('error', (err, stdout, stderr) => {
 console.log(err);
 console.log('Stdout: %o', stdout);
 console.log('Stderr: %o', stderr);
 })
 .run();


With an input mp4 file, this code works, but with a mov-file it fails. I get the following error :


Error: ffmpeg exited with code 1: Error demuxing input file 0: Invalid data found when processing input
pipe:0: Invalid data found when processing input
Cannot determine format of input stream 0:0 after EOF
Error marking filters as finished
Conversion failed!

Is it possible to convert multiple filetypes with one fluent-ffmpeg chain. If not, can someone help me to make a chain for mov ?
