Error: write EPIPE about editly

[mifi]

It doesn't finish rendering the two first clips, it just opens them and starts streaming from them. Because editly is based on streams, it will buffer up a bit first, and then try to write to output ffmpeg. What fails is when it's trying to write to the output:

editly/index.js

Line 396 in 4a6d593

await new Promise((r) => outProcess.stdin.write(outFrameData, () => r()));

So it indicates that the output ffmpeg failed to start or has stopped.

I agree we should add a lock file, but we need one for yarn and one for npm. I'm not sure the best way to keep them in sync. I usually use yarn, but when users run npm install -g they need npm lockfile

[NickBusey]

Huh, apparently I'm a dummy and didn't have ffmpeg on this machine, thought I did. Maybe could add a check and error message? Or a note in the readme maybe, either way I'll close this.

[mifi]

Yes I want to add a better check, so keeping it open until that's done

[mifi]

Whoops! I suspect your ffmpeg doesnt support gif output. Can you try to set these and run again:

enableFfmpegLog: true,
Verbose: true,

A docker image for this would be great. I could maybe look at putting a Dockerfile together if there's interest.

[mifi]

oops my phone auto-capitalized the V in Verbose. try verbose: true instead. As for why you are not getting any ffmpeg output is a bit strange. with verbose, it should print the ffmpeg gif output command, maybe you can try to run it on the command line.
also does it work with mp4?

Docker file could be possible, but since editly uses headless openGL and GLSL, it may be a bit tricky to set up

[chapmanjacobd]

this situation actually looks like the problem might not be ffmpeg because it renders the first two clips successfully right? so maybe it is a problem with createFrameSource gl

---

we might want to look keeping package.json.lock or yarn.lock in the repo. that way we can have much more predictable results: https://medium.com/the-guild/how-should-you-pin-your-npm-dependencies-and-why-2b8d545c7312

[chapmanjacobd]

found this:

https://stackoverflow.com/questions/46904544/sync-yarn-lock-back-into-package-json-and-lock
https://classic.yarnpkg.com/blog/2018/06/04/yarn-import-package-lock/

[mifi]

I want some solution that "just works" without having to run any extra commands before or after npm install or commit, and I prefer to use yarn during development, because it's much faster and more stable.

Also I also found this:
https://medium.com/@gajus/stop-using-package-lock-json-or-yarn-lock-909035e94328

editly is kind of in a limbo here because it is a library which can be a dependency of other packages, but at the same time it is also a stand alone CLI.

So if it's right to provide a lockfile, I think we need to provide a package-lock and a yarn lock. But when developing I prefer yarn, so I think package-lock should automatically be generated from yarn lock (I'm not sure though)

https://github.com/imsnif/synp

[chapmanjacobd]

maybe we should move this discussion into another issue to get more feedback from other users. I agree that we should provide both package-lock and yarn lock.

I think one of the big problems with libraries in the npm ecosystem is that it has become a practice to not include lock files for minor reasons or to follow some convention. Yes there are some costs like potential duplication but we will have less confusion if we know for sure that everyone is on the same page running the same dependencies.

Responsible development requires that your script works with the latest versions of dependencies (and yes that includes transitive dependencies) satisfied by semver.
https://medium.com/@gajus/stop-using-package-lock-json-or-yarn-lock-909035e94328

I don't at all believe this is true. When we don't commit package lock then we are setting up future devs for failure. We can't be expected to predict the future and know that none of the upstream dependencies breaks this library in some way (breaking semVar is absolutely possible)

[chapmanjacobd]

@NickBusey what is the output of ffmpeg -version ?

[chapmanjacobd]

I wonder if the problem is that vf is not quoted like this:

ffmpeg -f rawvideo -vcodec rawvideo -pix_fmt rgba -s 720x1280 -r 30 -i - -map 0:v:0 -vf \
"fps=30,scale=720:1280:flags=lanczos,split[s0][s1];[s0]palettegen[p];[s1][p]paletteuse" \
 -loop 0 -y test.gif

[mifi]

Have now improved error handling so it shows better error messages. @chapmanjacobd feel free to open a new issue about package-lock

With these configs it works on my pc, but when I try on my droplet gives me that error.

@thurdev I think your error is "Fontconfig error: Cannot load default config file". maybe missing something related to that?

[thurdev]

So I added this to my dockerfile

# FONT CONFIG
RUN apt-get install fontconfig -y

but didn't seem to fix the problem the EPIPE problem, but the Fontconfig error seems to be fixed now.

I also updated my ffmpeg to the latest version
