Broken ffmpeg commands for Intel GPUs on Linux

[felix920506]

Classifications

• Running python ./jellybench_py/hwi.py manually (within the Poetry shell) works and produces correct results.
• This happens on a Virtual Hardware (VM, WSL, ...)
• The issue occurs during the benchmark section of the script (after Starting Benchmark...).
• A server issue or faulty server response is causing the problem.
• jellybench was run in --debug mode (recommended for issue reports).
• I am using the latest version (branch develop) of jellybench. I understand older versions are not supported.

Description

When run jellybench with --nocpu option the following exception is thrown when starting benchmark

1. start jellybench with --nogpu flag
2. start benchmark
3. see error

x86_64 (64-bit)

Python Version

3.12.3

CPU[s]

Intel Core i5-10400F

GPU[s]

Intel Arc A750

Additional Context

Benchmark starts properly without the --nocpu flag

Possible Solution

No response

Tested on Windows with 5800X3D and RTX3060TI, does not happen.

[felix920506]

Did some more troubleshooting, there are 2 problems happening at the same time

1. The server is sending an outdated ffmpeg build which does not work on my system

2. The client is not correctly handling the error

[felix920506]

Ubuntu 24.04 and latest Popos are all affected

@felix920506 if you're still interested in getting this to run on ubuntu, and if you're ok with running it in docker, this might be useful: #85

I was getting the same UnboundLocalError when building this on Ubuntu Noble without letting the LSIO startup scripts handle linking and stuff. You might need to use a different dockermod though, since you're targeting Intel.
