Handbrake starting encode, then immediately completing encode with 0kb output

[Aerochill]

Problem Description

I am using Handbrake with autovideoconverter. When I try to use the watch folder with autovideoencoder the process just ends up like I stated in the title.

Doing so through the Handbrake GUI, however, yields expected results. I've combed through the logs and I can't seem to figure out why it is "succeeding" to encode nothing.

Activity Log, Crash Log or any other details

What Operating System are you running?

TrueNAS Scale 24.04

What version of HandBrake are you running?

1.7.3

Where did you download HandBrake from?

TrueNAS handbrake implementation

[sr55]

Can you provide an encode log for the GUI so we can see what your doing?

Are you sure the CLI is actually 1.7.3?

[Aerochill]

I am sure the CLI is 1.7.3

Here is the encode log from a successful encode in the GUI

YGO Omega 2024-04-23 10-41-52 2024-04-24 10-18-52.log

[sr55]

Assuming a a file that doesn't work on the CLI works with the GUI consistently, I have no idea. It's getting hung up on hardware from the looks but there is no obvious reason for it.

I have no idea what autovideoconverter is but if it's containerised HandBrake in any way, it may be the container causing issues.

Beyond that, I don't have any suggestions I'm afraid.

[Aerochill]

I have learned some things. It appears that the encode only behaves like this with extremely large or small files

with my 300 MB file with multiple files I was able to encode every time.

But with anything less than 150MB and any of my files larger than 1500 MB I was not able to encode

I saw someone talk about an issue like this in a different forum, but I dont remember where

[sr55]

There are no filesize limits. Folks are regularly encoding multi-hundred GB files with HB without issue.

Your not doing this on a network drive are you?

[itsTyrion]

I've had that a couple of days ago when trying to to a 4k transcode (SVT-AV1 10bit) with a lot of stuff open, but I forgot about the encode and wasn't able to reproduce it later on so there's at least a chance this wasn't a one-time fluke
