Issue when running MP4Box

[DxTa]

Hi, I've managed to run: read_and_feed.py, queue and the API at the same time. However, I got the following issue near the end of the API /encode process: "[Importer] Unknown input file type for "/tmp/tmpjtkwmf5m".

I guess this was coming from the MP4Box command.

FYI, this was running inside docker containers and using image ultravideo/kvazaar

Hi,

the Docker hub image for ultravideo/kvazaar was already 4 years old and might have caused problems, it's updated now so if you can try again to see if it works.

Thanks, I managed to get latest kvazaar version (2.2.0), and the gapac conversion step is still the issue, although I seems to get new error now

ultravideo  | [Importer] Unknown input file type for "/tmp/tmppa97q4js"
ultravideo  | Error importing /tmp/tmppa97q4js: Corrupted Data in file/stream

What I have tried to debug:

1. I tried to run ffmpeg alone and output to mp4 file, which is playable
2. I tried to simplify the kvazaar command a bit more (below) just to smoke test how kvazaar running
3. After that, the file got input to MP4Box command and I got the above error

encode_command = [
        "kvazaar",
        "--input-fps", "30",
        "-i", "-",
        "--input-res", resolution,
        "-o", str(out_file),
]

A bit more on the testing environment, I run it inside docker with python3.9, and the resolution environment is set to 480x360 for faster in running read_and_feed.py
