Can't export video

[AustinGil]

Hey, this seems like a really awesome project. I got everything working fine and was able to create a project and import the audio clip, but for some reason, when I try to export the video, it just doesn't work.

The progress bar goes all the way to 100% and then it says it's trying to output the file, but nothing happens.

Note that I am using the Linux version and my audio file is over an hour long, so it takes a very long time. Could it have something to do with this?

[mikecao]

Can you trying rendering a shorter clip, like 10 seconds, and see if that finishes? You can also watch your system for the ffmpeg process and see if it's still running.

[AustinGil]

Yeah, I thought about this already and tried with a 7 second audio and it still did not work.

[mikecao]

I'll see what I can find, but I don't have a native Linux install, only a VM and some things are buggy.

[AustinGil]

Yeah, I understand. Most folks dont use Linux so Im never surprised if something doesnt work. I noticed the project is built on Electron. Is it possible for it to just work in the browser then?

[mikecao]

The core of the application could run in a browser, but none of the file saving or rendering because that relies on Node.

So I did some testing in my VM and it looks like the rendered frames aren't being piped to the ffmpeg process. I don't really have a solution since it works in Windows and Mac, but at least I know what the problem is.

[AustinGil]

Oh yeah, that makes sense. I've run into some other ffmpeg issues before. Im not sure if it's installed with Ubuntu by default, but I do have it installed now, so Im not sure what the problem is. Either way, it doesn't sound like something that is easily solved. The project is still really cool, and I hope I can use it some day :)

@AustinGil Can you try running the latest version from master? I've made some updates the video rendering. See if it works for you. You should be able to open the developer tools and see messages from ffmpeg.

[AustinGil]

I downloaded the master branch an unpacked it, then went through the install scripts. I tried running yarn start and got

Error launching app

After that I tried yarn dev and got things to run in the terminal, but the browser showed the following errors.

[mikecao]

Sorry I missed a step. You need to run yarn init-app first. I'll need to update the scripts later.

[mikecao]

Made some updates, pull the latest from master.

[AustinGil]

Pulled the latest version and ran:

yarn install-ffmpeg
yarn install
yarn init-app
yarn start

And got the error:

yarn run v1.22.10
$ dotenv electron ./app
Error launching app

I tried again after closing some other node apps and the electron app opened up, but only shows a black screen. Terminal shows:

yarn run v1.22.10
$ dotenv electron ./app

[mikecao]

You missed the yarn dev step. I should probably update the README to be more clear about running a dev build vs a normal build. If you just want a production build then run yarn build followed by yarn start.

[AustinGil]

Well, to be honest with you, I tried yarn dev as well and it did not work, but I dont remember what the issue was. I just assumed the right command was yarn start

[pymaldebaran]

I have the exact same problem as @AustinGil : running astrofox under Fedora Linux using the AppImage everything works fine until I try to render the video. I could build tha app from master following the instruction here but got stuck with a black window when launching app via yarn start. exact same error as @AustinGil :

yarn run v1.22.5
$ dotenv electron ./app

Note: the framebuffer message does not show immediatly but only after some few seconds (or if I click on the network tab of the debugger).

I faced exactly the same problem on Linux. Used latest version from master. Found in developer tools console after many tries to export video:

Error: Uncaught Error: spawn ../astrofox/bin/ffmpeg EACCES

chmod a+x astrofox/bin/ffmpeg

So I fixed binary permission with the command above and webm video export is working! But exporting to mp4 looks like corrupted. After the process appears to be complete, the application turns completely black, no controls, nothing.

[mikecao]

Please try the latest version 1.2.0

[AustinGil]

Thanks @mikecao. First run seems to be working. Tested on a very short clip. I'll try a normal sized file next. So far so good :)

@mikecao Had the same problem. Couldnt export videos or images. My antivirus(Avast) blocked it somehow. By disabling it it works...
