Audio only downloads don't play properly about youtubedl-material HOT 10 CLOSED

Weird, I was not able to reproduce this bug. Are there any errors that come back from the frontend or backend? I'd like to better understand where it failed here.

Sorry, there's no errors at all other than the error message with quicktime player. Everything seems to work it's just delivering an invalid file.

@Tzahi12345 Thanks for this awesome project.
I'm using YoutubeDL-Material in a docker container and can confirm this issue. With this video I cannot even get it to work in the browser.
When I download the video audio only and click on play, the clip is only one second and has no audio. The downloaded MP3-file is 4.2 MB, so it seems to be fine but nevertheless I am unable to play it using VLC, iTunes, ...
I'm happy to help you digging further into this issue, if you have any idea where to look for errors.

@LukasK13 Thanks for the confirmation. Can you verify that no errors appeared in in the backend as well? It's the node app.js screen, if you are using Docker it would appear after you run docker-compose up.

I can confirm that there are no errors shown in the container logs.

Still not able to reproduce, really strange...

Just a thought: maybe it has to do with the youtube-dl version?

The latest update (3.4 includes a newer (March 2020) version. Could you try the updated version and see if the error persists?

from youtubedl-material.

The problem still exists in the latest update 3.4.
However I digged a little further.
I am running YoutubeDL-Material 3.4 in docker on ubuntu server 19.10. My main machine is a MacBook Pro with MacOS Catalina. As I am not sure if the browser playback and media player playback (VLC, Quicktime, ...), I'm listing both issues separately.

Browser Playback

MacOS Catalina

• Safari: Playback is one second with no audio
• Firefox: Playback is working fine 🎉
• Chrome / MS Edge Chromium: Playback is working fine 🎉

Windows 10

• Firefox: Playback is working fine 🎉
• MS Edge Chromium: Playback is working fine 🎉

Playback of downloaded MP3

This is not depending on which browser was used for downloading the audio. An error message is never shown.

MacOS Catalina

• iTunes: Playback is not working
• VLC Media Player: Playback is one second with no audio
• QuickTime Player: Playback is 15 seconds with no audio

Windows 10

• VLC Media Player: Playback is one second with no audio
• Windows Media Player: Playback is working fine 🎉

I think I see what is happening. The audio file that is downloaded is not actually an mp3, it's either a webm or mkv file that is just named as an mp3.

I used a file analyzer that confirmed by suspicions:

I'll see if I can get a hotfix out today for it, probably won't take long to fix. I'll close the issue once that's done. Anyways, thanks @LukasK13 for the debugging help! The inconsistent behavior in media players from your testing was really helpful.

Thank you very much for the fast fixing.
I'm glad I could help.

from youtubedl-material.

No problem! Hotfix is out, just pull the new 3.4 image or download the latest zip from the releases :)
