Error muxing packet

[tmarkov]

When trying to upscale a file (avi), I'm getting an error:

[2024-11-03 02:29:45.484] [error] Error muxing packet
[2024-11-03 02:29:45.484] [error] Error encoding/writing frame: Invalid argument
[2024-11-03 02:29:45.484] [error] Error processing frames: Invalid argument

Any idea what could be causing that? I am able to play the file normally. That said, I'm seeing this with either libplacebo or realesrgan.

It might be related to the subtitle. Is the subtitle gone?
