ffmpeg 4.0 NVIDIA NVDEC-accelerated Support ?

ffmpeg 4.0 has released the NVIDIA NVDEC-accelerated H.264, HEVC, MJPEG, MPEG-1/2/4, VC1, VP8/9 hwaccel decoding added.

see more ffmpeg 4.0 NVENC

so, Is it possible to increase support for gpu acceleration?

my ffmpeg

Use -h to get full help or, even better, run 'man ffmpeg'

Here is my idea:

1. complied ffmpeg with nvidia video sdk : https://developer.nvidia.com/ffmpeg or use docker image https://hub.docker.com/r/nightseas/ffmpeg/
2. modified the ffmpeg_reader.py in moviepy

moviepy/video/io/ffmpeg_reader.py line89-95

    cmd = ([get_setting("FFMPEG_BINARY")] + i_arg +
           ['-loglevel', 'error',
            '-f', 'image2pipe',
            '-vf', 'scale=%d:%d' % tuple(self.size),
            '-sws_flags', self.resize_algo,
            "-pix_fmt", self.pix_fmt,
            '-vcodec', 'rawvideo', '-'])

I guess the cmd is made up of multiple parameters, so I modified as the following

    cmd = ([get_setting("FFMPEG_BINARY")] + i_arg +
           ['-loglevel', 'error',
            '-f', 'image2pipe',
            '-vf', 'scale=%d:%d' % tuple(self.size),
            '-sws_flags', self.resize_algo,
            "-pix_fmt", self.pix_fmt,
            '-vcodec', 'h264_nvenc',
            '-preset', 'default'])
            #'-vcodec', 'rawvideo', '-'])

BUT, I got ：

 MoviePy error: failed to read the first frame of "
                           "video file test.mp4. That might mean that the file is "
                           "corrupted. That may also mean that you are using "
                           "a deprecated version of FFMPEG. On Ubuntu/Debian "
                           "for instance the version in the repos is deprecated. "
                           "Please update to a recent version from the website."

check the file 'moviepy/video/io/ffmpeg_reader.py line 135-140

        if not hasattr(self, 'lastread'):
            raise IOError(("MoviePy error: failed to read the first frame of "
                           "video file %s. That might mean that the file is "
                           "corrupted. That may also mean that you are using "
                           "a deprecated version of FFMPEG. On Ubuntu/Debian "
                           "for instance the version in the repos is deprecated. "
                           "Please update to a recent version from the website.")%(
                            self.filename))

maybe not hasattr(self, 'lastread') is the problem.

Is there another way to solve this problem?

What ended up happening with this?

I’m also interested if anyone found a way to enable ffmpeg gpu acceleration in moviepy?
