    Re: M5Stack UnitV2 apriltag: how fast can read? FPS?

    Not sure about apriltags. But video recording to sdcard with ffmpeg runs at the following speeds:

    framerates:

    • 30fps @ 640x480
    • 20fps @ 1280x720
    • 9fps @ 1920x1080

    video only:
    ffmpeg -f v4l2 -i /dev/video0 -c:v mpeg4 -s 640x480 output4.mp4

    with audio like:
    ffmpeg -f v4l2 -i /dev/video0 -f alsa -i default -c:v mpeg4 -s 640x480 -c:a aac -ar 44100 -ac 2 -b:a 192k output-x.mp4

    h264 and vp8 should be present, but don't work.

    Note: the cameras of Unitv2 and UnitV2-M12 are quite different and the latter (M12) has MUCH higher quality! It's not only the lens, also the sensor.
