Plugin frame crash in FULL HD

[felicemarra]

I'm trying to write a plugin.

If I try to write a frame 640x360 everything is ok... but If I increase the resolution it crash..
1280x720 crash
1920x1080 crash
640x360 works

    const int width = 640;
    const int height = 360;

    uint8_t pixels[width * height * 4];
    uint64_t cur_time = os_gettime_ns();
    obs_source_frame frame = {};
    frame.data[0] = pixels;
    frame.linesize[0] = width * 4;
    frame.format = VIDEO_FORMAT_BGRA;
    frame.full_range = false;
    frame.width = width;
    frame.height = height;
    frame.timestamp = os_gettime_ns();
    for (int x = 0; x < width* height* 4; x++) {
        *(pixels + x) = 255;
    }
    obs_source_output_video(source, &frame);

It crash on copying frame. So I understand output frame is not so big as source frame. Where can I set the output frame size?
