Transcoding

Synchronous API

from ffmpeg import FFmpeg


def main():
    ffmpeg = (
        FFmpeg()
        .option("y")
        .input("input.mp4")
        .output(
            "output.mp4",
            {"codec:v": "libx264"},
            vf="scale=1280:-1",
            preset="veryslow",
            crf=24,
        )
    )

    ffmpeg.execute()


if __name__ == "__main__":
    main()

Asynchronous API

import asyncio

from ffmpeg.asyncio import FFmpeg


async def main():
    ffmpeg = (
        FFmpeg()
        .option("y")
        .input("input.mp4")
        .output(
            "output.mp4",
            {"codec:v": "libx264"},
            vf="scale=1280:-1",
            preset="veryslow",
            crf=24,
        )
    )

    await ffmpeg.execute()


if __name__ == "__main__":
    asyncio.run(main())

Recording

Synchronous API

from ffmpeg import FFmpeg, Progress


def main():
    ffmpeg = (
        FFmpeg()
        .option("y")
        .input(
            "rtsp://username:[email protected]/cam",
            rtsp_transport="tcp",
            rtsp_flags="prefer_tcp",
        )
        .output("output.mp4", vcodec="copy")
    )

    @ffmpeg.on("progress")
    def time_to_terminate(progress: Progress):
        if progress.frame > 200:
            ffmpeg.terminate()

    ffmpeg.execute()


if __name__ == "__main__":
    main()

Asynchronous API

import asyncio

from ffmpeg import Progress
from ffmpeg.asyncio import FFmpeg


async def main():
    ffmpeg = (
        FFmpeg()
        .option("y")
        .input(
            "rtsp://username:[email protected]/cam",
            rtsp_transport="tcp",
            rtsp_flags="prefer_tcp",
        )
        .output("output.mp4", vcodec="copy")
    )

    @ffmpeg.on("progress")
    def time_to_terminate(progress: Progress):
        if progress.frame > 200:
            ffmpeg.terminate()

    await ffmpeg.execute()


if __name__ == "__main__":
    asyncio.run(main())
