  How to cut a video to a certain length and add an intro video to it using ffmpeg-python ?

  


  What i am doing is :

  


          intro = ffmpeg.input(intro)
        mainvid = ffmpeg.input(mainvid)

        v1 = intro.video
        a1 = intro.audio
        v2 = mainvid.video
        a2 = mainvid.audio

        joined = ffmpeg.concat(v1, a1, v2, a2, v=1, a=1).node
        v3 = joined[0]
        a3 = joined[1]

        (
            ffmpeg
            .output(
                v3,
                a3,
                'out.mkv', 
                vcodec='libx265', )
            .run()
        )


  


  But i dont know how to cut mainvid to a certain length like 10 mins before joining, i know ss will help but dont know how to use it for only mainvid.

  


• Stream video from python code(ffmpeg)

  31 janvier 2018, par R-Cronj

  I have video frames from below code

  (grabbed, frame) = camera.read()

  Now I want to stream this live video from my python code.

  I plan on using ffmpeg but please do tell me if I can do this with another tool.

  I have tried this but didn’t work :

  subprocess.call(["ffmpeg", "-f", "rawvideo", "-pixel_format", "bgr24", "-video_size", "544x576", "-framerate", "25", "-i", "-", "http://localhost:8090/feed1.ffm"], stdin=frame.tostring())

• Python code to concat images and ts files using ffmpeg

  10 décembre 2019, par srt243

  I have a folder with multiple ts files in it and I want to join the files by inserting an image for n number of duration between videos. Below is the list with the duration for which an image needs to be inserted for.

  ['00:00:06:17', '00:00:00:16', '00:00:01:05', '00:00:00:31', '00:00:01:01']
  For example, if the folder has 5 ts files (this number might change so the folder needs to be iterable) then,

  video1 + image for 00:00:06:17 + video2 + image for 00:00:00:16 + video 3, etc...

  Any pointers will be much appreciated.

  UPDATE :

  for i in new_ts3:
  
      for m in filename[:-1]:
  
          p1 = subprocess.Popen (['ffmpeg', '-loop', '1', '-i', sys.argv[2], '-c:v', 'libx264', '-profile:v', 'high', '-t', i, '-pix_fmt', 'yuvj420p', '-vf', 'scale=1280:720', '-f', 'mpegts', '{}{}_.ts'.format((os.path.splitext(sys.argv[1]) [0]), m)], stdout=subprocess.PIPE)
  
          out1 = p1.communicate()
  
      break

  where new_ts3 is ['00:00:06:17', '00:00:00:16', '00:00:01:05', '00:00:00:31', '00:00:01:01'] and

  filename is ['file1', 'file2', 'file3', 'file4', 'file5', 'file6']

  With the above, I am getting 5 files with different filenames but each file is of duration 00:00:06:17
