Hello,
Our Heroku setup does not include ffmpeg so you will have to figure out how to install it by yourself.

When I finished redeploying, I noticed that the site was not different and no new transcripts were added.

What were you expecting to see? You added a screenshot of the format list but this list contains the formats available on the video website, so having ffmpeg will not influence this list.
I suppose you want to enable conversion?

yeah, I want enabel conversion. convert video to mp3.

How should I do to enable this function in heroku?

Hello, I am really in need of your help. 😭😭😭😭 I've finished the project with i10n in Traditional Chinese, but I haven't finished testing it yet because ffmpeg doesn't work. 😭😭😭😭

Please don't spam this issue! I am working on this project on my free time.

If you want to enable MP3 conversion, you can add CONVERT=1 to your Heroku configuration.

I see, sorry.

If you want to enable MP3 conversion, you can add CONVERT=1 to your Heroku configuration.

Oh! Okay, I will try it~

Do I still need to solve a problem?

If ffmpeg is not installed at /usr/bin/ffmpeg, you will need to set the FFMPEG environment variable with the correct path.

@chiyi4488 Heroku supports ffmpeg as a buildpack

@oscarhong Wow! This is amazing! Thank you for solving my problem!

@oscarhong Oh wait, can you teach me how to set it up? Because I think I found your work before, but it didn't work.

You should put the FFmpeg buildpack above the other two language buildpacks.

After that, you can do a redeploy by git push heroku master to make sure FFmpeg is installed correctly.

To confirm the location of FFmpeg, you can run heroku run which ffmpeg, which would come back with something like /app/vendor/ffmpeg/ffmpeg

Then you can set the FFMPEG environment variable with that path.

Thank you @oscarhong ! It worked!Here is my successful config file for the next person who is confused!
