FileNotFoundError out_final.mp4 about unsilence HOT 4 OPEN

Doing some investigation, I think this is an issue of process management. Subprocesses are failing but this isn't getting surfaced.

I didn't have ffprobe set up, but the project relies on it. Maybe it goes without saying that having ffmpeg means also having this tool, but it's unclear to me being relatively unfamiliar with ffmpeg.

I've also found that some of the ffmpeg invocations are getting killed, probably because a t3.nano doesn't have enough memory.

Retrying with fixes to the above problems, but I think the bug is still valid - unsilence should be bubbling up these errors, without them it's taking a long time to track this down.

Yep that fixed the problem. This is a bug about not reporting/detecting subprocess failures.

Hello, I have the same issue but I'm on a windows installation using anaconda with python 3.9.13, and ffmpeg 4.3.1. It seems like my ffprobe is setup correctly cause I can invoke it, but i'm not sure how to confirm if any ffmpeg invocations are being killed as I believe I have enough memory. What exactly did you do to remedy these issues?

@Seishirou101 For me it was just ffprobe and running on a bigger ec2 instance.

I'd recommend running via "Installation as library (from source)". That way you can edit the code to do some troubleshooting (re-run the setup.py part after editing code).

Try looking at the .tmp files. They should be video segments, and you get unreasonably small ones (48 bytes) when this issue occurs.

Then print the commands used to generate the files. For any files that are messed up, try running them manually to see if you can get more detail.
