ffmpeg not installed on nextcloud snap

[ManuXD32]

Describe the bug when opening the ncdownloader a message appears telling that ffmpeg is not installed, but it is installed.

Hi, could you please post your administrative logs? Log into your NextCloud as the administrator, navigate to Settings and then Logging.

Could you please tell us what operating system and version you are running NextCloud on? You can find this information by running the following command at the command line:

lsb_release -a

Next, could you please tell us what version of NextCloud, NCDownloader, and ffmpeg you are using?

• You can find NextCloud version from the Administration Overview page under your administrator's account settings.
• You can find the NCDownloader version by going to the Apps page under your administrator account and selecting NCDownloader.
• You can determine your version of ffmpeg by typing:

ffmpeg -version

at the command line.

Lastly, please paste the output of the following command:

whereis ffmpeg

Once we have this information we can determine what is going on. I suspect that we will need to change the path of ffmpeg in the settings of NCDownloader.

I have the same problem.

Logging doesn't log an error or a warning for ncdownloader. Running NC 24.0.7 and ncDownloader 1.0.2

Distributor ID: Ubuntu
Description:    Ubuntu 20.04.5 LTS
Release:        20.04
Codename:       focal

ffmpeg version 4.2.7-0ubuntu0.1 Copyright (c) 2000-2022 the FFmpeg developers

Same problem here

Found out it's because containerization of the snap. So it's not a NCDownloader problem, necessarily. I got it working by downloading the ffmpeg binary and placing it in:

/var/snap/nextcloud/common/nextcloud/data/bin

Need to do it as root: sudo su

That way it should not get overwritten when the snap is updated. That location is in the path of the snap container so should be seen then. If not, then update the settings for bin/ffmpeg.

I did this a while ago and should have updated this then when it was on my mind, I think that's all I did. For @shiningw we could keep this open, as I think this is being addressed in the latest nextcloud snap n26 as this issue affects a whole host of tools (video thumbnails, etc.). But when they do, it may be worth seeing if NCDownloader needs to add an option to locate ffmpeg when it's addressed.

@traeblain I copied it into the directory (tho the bin directory didn't exist). I still get the same error message about ffmpeg missing.

[traeblain]

Make sure you got it in the right spot and that it's executable. chmod a+x ffmpeg

This is where NCDownloader looks for binaries:

https://github.com/shiningw/ncdownloader/blob/c28cbd4cac8e35abec5d0eb7a020184ecce5fa2c/lib/Tools/Helper.php#L225

Notice the last item in that list: $dataPath . "/bin" So if you have it in the right spot and it can be executed, NCDownloader should be able to see it.

[idoodler]

@traeblain I did exactly that.

• changed to su with sudo su
• cp /usr/bin/ffmpeg /var/snap/nextcloud/common/nextcloud/data/bin/ffmpeg
• chmod a+x /usr/bin/ffmpeg /var/snap/nextcloud/common/nextcloud/data/bin/ffmpeg
• validated that it is executable /var/snap/nextcloud/common/nextcloud/data/bin/ffmpeg -h
• restarted nextcloud snap restart nextcloud

This results in the same error

Ok that’s not NCDownloder not finding ffmpeg, that is yr-dlp. In the setting try this line.

‘ bin/yt-dlp --ffmpeg-location bin/ffmpeg ‘

Or where your yt-dlp is located.

@traeblain I am redoing my home server now. So I switched to docker contaienr. Of course I have the same issue now 🫣.

I tried to create a mount for ffmpeg in usr/bin. This worked (a bit), but when the download finished I get an esception that a lib can‘t be found. I guess its the lib used to concat the .mp4 with the .m4a. I am quite new to docker, so I have to learn a bit more. Just want to inform you guys not that you think I ghosted you 😅

The same issue happened on the snap installation

Nextcloud 25.0.4 NCDownloader 1.0.2 ffmpeg version n5.1.2 Operating System: Linux 5.15.92-1-MANJARO-ARM-RPI aarch64

[pekkle-hksar]

do it as root

copy ffmpeg to folder /var/snap/nextcloud/current/nextcloud/extra-apps/ncdownloader/bin edit /var/snap/nextcloud/current/nextcloud/extra-apps/ncdownloader/lib/Tools/Helper.php add following in the function findBinaryPath()

$paths = ['/usr/local/sbin', '/usr/local/bin', '/usr/sbin', '/usr/bin', '/sbin', '/bin', '/opt/bin', $dataPath . "/bin", __DIR__ . "/../../bin"];

It should works immediately. Hope it helps :)
