Crash if ffmpeg reports N/A for speed

[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

If ffmpeg returns N/A for speed for whatever reason, the program throws an exception and exits.

If N/A is returned for speed the same test should be re-ran
