write a Image object into std.in buffer

See original GitHub issue

I’m working on streaming image sequences into ffmpeg. Roughly, this is my code:

image_original = pyvips.Image.new_from_file(self.file_path)

p = Popen(['/usr/local/bin/ffmpeg', '-y', '-f', 'image2pipe', '-vcodec', 'mjpeg', '-r', self.fps, '-i', '-', '-r', self.fps, '-f', 'mp4', '-vcodec', 'libx264', '-crf', '26', 'output/{}.mp4'.format(self.animation_name)], stdin=PIPE)

for image in images:
    image.smartcrop(self.output_raster_width, self.output_raster_height)
    image.jpegsave(p.stdin, profile='JPEG')

p.stdin.close()
p.wait()

This yields an error, but I suspect I’m not using the right method to do the sdtin write. Is there a good way to handle this use case?

Hi again, do you mind if I close this issue? It’s confusing having two open for almost the same thing. Let’s continue discussion in the other one.
