ValueError: invalid literal for int() with base 10: "2097152'"

[baltic-tea]

I encountered this error while deploying a Docker application on Debian (python:3.11-slim-bullseye).

Full output of error:

ValueError: invalid literal for int() with base 10: "2097152'"

I fixed this error by changing the one line in the ./ffmpeg/statistics.py.

_field_factory = {
    "frame": int,
    "fps": float,
    "size": lambda item: int(item.rstrip(r"'kB ")) * 1024,
    "time": parse_time,
    "bitrate": lambda item: float(item.replace("kbits/s", "")),
    "speed": lambda item: float(item.replace("x", "")),
}

Before: "size": lambda item: int(item.replace("kB")) * 1024 After: "size": lambda item: int(item.rstrip("'kB ")) * 1024

Hi! I solved this issue on v2.0.6. Thanks for reporting the bug.

[aa-reznik]

@jonghwanhyeon sorry for late comment, but face same error on ffprobe 6.0 and 6.1. On 4.4.1 and 4.4.2 all is ok. Binary ffmpeg and ffprobe from here: mwader/static-ffmpeg:6.0 and mwader/static-ffmpeg:6.1

[jonghwanhyeon]

@aa-reznik Can you show me a code you use?

[aa-reznik]

@jonghwanhyeon yes, it's very simple function.

import json
import os

from ffmpeg.asyncio import FFmpeg

async def get_local_media_metadata(local_file_path: str) -> dict:
    """
    Retrieves metadata for a local media file.

    Args:
        local_file_path: The file path of the local media file.

    Returns:
        dict with results.
    """
    ffprobe = FFmpeg(executable="ffprobe").input(
        local_file_path,
        print_format="json",
        show_streams=None,
        show_format=None,
    )

    media = json.loads(await ffprobe.execute())
    metadata = {
        "duration": round(float(media["format"]["duration"]), 2),
        "size": int(media["format"]["size"]),
        "size_mb": round(float(media["format"]["size"]) / 1024 / 1024, 2),
        "bitrate_kbps": round(float(media["format"]["bit_rate"]) / 1024, 2),
    }

    try:
        video_streams = [
            stream for stream in media["streams"] if stream["codec_type"] == "video"
        ]
        width, height = video_streams[0]["width"], video_streams[0]["height"]
        metadata.update({"width": width, "height": height})
    except Exception:
        pass  # No video stream, it's ok

    return metadata

used python-ffmpeg==2.0.7 and

COPY --from=mwader/static-ffmpeg:6.0 /ffmpeg /usr/local/bin/
COPY --from=mwader/static-ffmpeg:6.0 /ffprobe /usr/local/bin/

in docker file.

Same exception as above, no matter what mp4 file is on input:

File "/usr/local/lib/python3.10/site-packages/ffmpeg/statistics.py", line 19, in <lambda>
    "size": lambda item: int(item.replace("kB", "")) * 1024,
    ValueError: invalid literal for int() with base 10: "2097152'"

[jonghwanhyeon]

Fixed! Please use version 2.0.8. Thanks for helping me 🙏
