Error initializing complex filters. Invalid argument

[ivangayton]

Hi, thanks for publishing this! I have a team in Kenya creating 360-degree videos for a community mapping project, and I'm trying to decode them so I can feed them into photogrammetry software to create 3D models from them using OpenDroneMap and ODMax, a little utility my friends built to extract cubic faces and GPS positions.

ODMax does not, at this time, properly extract the weirdly encoded GoPro video to working 360, so I'm trying to adapt your script.

Whilst runing it locally, I'm encountering an error (full output at the end; here's just the error):

Error initializing complex filters.
Option not found

A few possibilities: early on there seems to be a warning [mov,mp4,m4a,3gp,3g2,mj2 @ 0x556ad5f1e540] Using non-standard frame rate 29/1. I suppose that might have something to do with it?

However, doing a web search for the exact error message seems to kick up a few issues with FFMPEG that might be relevant, such as this or this, which seem to be centered around quoting/escaping issues. Have you encountered anything like that? Do you have any immediate insights? (I'll continue investigating; I'm certainly not expecting you to jump immediately to my rescue, but if you do happen to have a quick guess as to what I'm doing wrong and can save me some investigation time, I'd greatly appreciate it!)

Hi @ivangayton , did you manage to solve this? I encounter exactly the same error message.

[ivangayton]

I'm afraid not @wavemaking. I haven't had time to solve it, and the project has moved on for the moment. I'll probably look at it again in a few weeks.
