Hi.

I've got quite many errors like the following in my log:

I started digging and it turns out I can't even run ffmpeg manually:

/opt/emby-server/bin/ffprobe: error while loading shared libraries: libavdevice.so.58: cannot open shared object file: No such file or directory

Don't really know how this works, but there is  a libavdevice.so.58:

root@rock64:/opt/emby-server# file /opt/emby-server/lib/libavdevice.so.58
/opt/emby-server/lib/libavdevice.so.58: symbolic link to libavdevice.so.58.9.100

Don't really know where to continue digging?

 

This is the official 4.3.0.30 package for arm64, running on Debian 10.02.

Hi there, you can't run our ffmpeg directly without first setting up things such as environment variables. It's something we can try to document when we have a chance.

 

As for your issue, since you're on arm64 I believe it is probably related to this:

https://emby.media/community/index.php?/topic/79567-server-crash-when-i-try-to-play-a-movie/

 

Strangely the problems are not observed on the beta channel even though they currently have identical code, so we're currently trying to chase down what the difference is. Thanks.

Yep, I kinda suspected it could be related. Thanks for looking into it! Please tell me if there's anything more I can do to help.

Then make sure to be in the /opt/emby-server directory before running the ffmpeg binary, as the loader path is relative to make the whole installation more portable.

Yep, after doing those exports the command runs. I ran the command with the exact same parameters that Emby is doing and got the same result (no output file was created). Not really clear on why though. Here is the output:

Thanks for the feedback. I'm told emby 4.3.0.24 is working fine, could you please check that version? If possible I'd like you to extract the command that is ran from that particular version so that I can compare it to the one in 4.3.0.30. Both ship with the exact same ffmpeg binary, so if anything isn't working it's probably down to the command.

Yep. I think I've found the culprit, it was there right in our faces all the time.

 

In .24 the command used for this exact episode is

/opt/emby-server/bin/ffmpeg -ss 00:08:07.520  -f avi -threads 1 -i file:"/mnt/nas/public/Serier/Trigger Happy TV/3x01 - Angry Cyclist.avi" -an -sn -threads 0 -vframes 1 -vf "scale=600:trunc(ow/a/2)*2,thumbnail=24" -f image2 "/var/lib/emby/cache/temp/96cb9986-a395-400b-a441-e90d4f4950f7.jpg"

...while for .30 it is

/opt/emby-server/bin/ffmpeg -ss 15:08:26.480  -f avi -threads 1 -i file:"/mnt/nas/public/Serier/Trigger Happy TV/3x01 - Angry Cyclist.avi" -an -sn -threads 0 -vframes 1 -vf "scale=600:trunc(ow/a/2)*2,thumbnail=24" -f image2 "/var/lib/emby/cache/temp/66fdc849-aa59-4b9d-88de-4de3223c5051.jpg"

The only different seems to be the ss option. So if I understand correctly, in version .24 it seeks eight minutes into the video, while in .30 it seeks over 15 hours. Which is far more than the total length of the video. So it seems someone simply broke how the seek time is calculated between .24 and .30.

Can you attach the emby server log from that, and the image extraction log, so that we can see context? Thanks.

Nope, no luck. It still tries to extract the thumbnail from a point in time way after the movie ended:

@@Malmgren - Does it work with the latest beta?

I went for the latest stable (4.3.1.0) instead and it seems to work now. I guess it's the same fix there as in the betas?
