• Where I made a mistake - FFmpeg (Linux) basic problem

  23 mars 2019, par Fejor

  I just started learning FFmpeg. I have code (like below), but it’s doing nothing.

  fmpeg -i videoplayback.mp4 -filter_complex "[1:v]trim=start=0:end=1,setpts=PTS-STARTPTS,scale=480x360,setsar=sar=16/9[intro1];
  
  [1:v]trim=start=1:end=123.39,setpts=PTS-STARTPTS,scale=480x360,setsar=sar=16/9[main1];
  
  [1:v]trim=start=123.39:end=124.39,setpts=PTS-STARTPTS,scale=480x360,setsar=sar=16/9[end1];
  
  [intro1]format=pix_fmts=yuva420p, fade=t=in:st=0:d=1:alpha=1[intro1];
  
  [end1]format=pix_fmts=yuva420p, fade=t=in:st=0:d=1:alpha=1[end1];
  
  [intro1][main1][end1][output];
  
  [a:1][audio]; -vcodec libx264 -map "[output]" -map"[audio]" "output.mp4"

• Very basic Moviepy script failing to run

  1er juillet 2018, par cem akbulut

  So, I have this very basic script that concatenates two videos, and adds a background sound.

  def intro():
  
  
  
      voiceoverIntro = AudioFileClip(audio[3]) #get path for intro.mp3
  
  
  
  
  
      introVideo = []
  
      temp = p1vid + p2vid + p3vid
  
  
  
      for x in temp: # add product videos to introVideo if they are longer than intro.mp3
  
          x = VideoFileClip(x)
  
  
  
          if x.duration >= voiceoverIntro.duration:
  
              introVideo.append(x)
  
  
  
  
  
      if len(introVideo) >= 1:
  
  
  
          #Get the video and turn off its volume
  
          introBg = introVideo[0].volumex(0).resize((1280,720))
  
          introBg = introBg.set_audio(voiceoverIntro).set_duration(voiceoverIntro.duration)
  
  
  
  
  
          introBg.reader.close()
  
          introBg.audio.reader.close_proc()
  
  
  
          return introBg

  And this function creates the second clip

  def productThreeOpener(productName):
  
      opener3 = VideoFileClip("media/number3.mp4").volumex(0).resize((1280,720))
  
  
  
  
  
  
  
      text = TextClip(productName,fontsize=60,color='white', font="Dekar")\
  
          .set_pos(("right", "center"))\
  
          .set_duration(3)\
  
          .set_start(2)\
  
          .crossfadein(1)\
  
          .crossfadeout(1)\
  
          .margin(right=200,opacity=0)
  
  
  
      opener3 = CompositeVideoClip([opener3, text])
  
  
  
      return opener3

  Now we just concatenate the two outputs

  final_clip = concatenate_videoclips([intro, productThreeOpener], method="compose")

  final_clip.resize((1280, 720)).write_videofile("output/intro.mp4", threads=8, fps=24, progress_bar=False)

  Running the code above returns this error ;

  I strictly followed MoviePY installation guide, installed it and all of its dependencies about 2 days ago. I work on a 64b Windows machine. Python version 3.6.1

  I’ve been stuck with this error for over a day now, and I don’t know what to try.. Any help/advice is highly appreciated.

  Thanks.
