Error selecting an encoder

[Luctia]

Question

How can I get rid of the Error selecting an encoder error?

Background

I'm trying to upscale an mp4 video, but keep getting an FFmpeg related error. Both FFmpeg and FFprobe are installed on my machine (Ubuntu). I have a 1080 graphics card. The workspace directory does get made, but the frames subdirectory is always empty.

Current Research Artifacts (COMPULSORY)

I obviously checked the docs here for a solution and couldn't find one. Then I went to Google, where I found some articles related to FFmpeg, but they all seemed to be for slightly different configurations. I saw a comment about having to install zlib1g-dev, but after doing this I get the same error.

Note that the error does not terminate the script. It happily continues "generating frames" that don't seem to actually exist (so I'm also wondering why it says [SUCCESS].

Attachment

This is my script:

#!/bin/sh
[...]/upscaler-v0.7.0/upscaler/start.cmd \
        --model upscayl-ultrasharp \
	--scale 4 \
        --format png \
	--input ./test.mp4 \
	--video

This is my log:

ffmpeg error. Looks like the ffmpeg failed to dissect the video. There is a test video in the repository, can you try test it out and revert back to me please?

If setup correctly, you only need to run this benchmark.cmd. That's our current way of testing whether the program is working on hardware configurations or otherwise.
