To use omxplayer you'll want to make sure your video is encoded with an H.264 codec and is in a file format like .avi, .mov, .mkv, .mp4, or .m4v. If you have a video in a different format or that won't play you convert it into an H.264 video easily with some free tools. For converting a video to H.264 that omxplayer can play I recommend the Handbrake video transcoder tool. This tool is available for free for Windows, Mac, and Linux machines, and has a relatively simple interface

omxplayer /opt/vc/src/hello_pi/hello_video/test.h264

Control - C pour terminer

  SCRIPT #1

  la meilleur technique par toons :

  import subprocess

  subprocess.call(['omxplayer --alpha 100 test.mkv'], shell=True)

  SCRIPT #2

  import os

  TheCommand ="omxplayer /opt/vc/src/hello_pi/hello_video/test.h264"

  os.system(TheCommand)

  SCRIPT #3 - argument

  import os

  import argparse

  parser = argparse.ArgumentParser()

  parser.add_argument("val", help="transparency", type=int)

  args = parser.parse_args()

  os.system("omxplayer --alpha args.val /opt/vc/src/hello_pi/hello_video/test.h264")
