• 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.

• How do I save `RTSP` streams as `*.mp4` files in Golang ? [closed]

  14 septembre 2021, par Clancy Zeng

  I need to use Golang to save the data from the RTSP stream to a *.mp4 video file for a specified length of time.

  


  I wanted to install an FFmpeg application and then call a command like this from Golang to solve my needs.

  


  


  ffmpeg -i rtsp ://192.168.108.132:8554/profile0 -r 16 -tt 60 /tmp/test.mp4

  


  


  But installing FFMPEG takes up hundreds of megabytes of space.So this idea was rejected by the leadership.

  


  Is there a pure Golang implementation library that can address my needs ?Or is there a golang-only library that parses RTSP streams and saves them as *.MP4 video files ?

  


• I cant save the animation in ffmpeg

  22 mai 2021, par Gokul

  i tried various examples though i cant find proper solution. This is the example code of my project i want to save this in a mp4 format and i used ffmpeg. the animation was saved if I use df = pd.DataFrame(np.random.rand(250,3)) but it is not working for my sample code, it showed key error = 0. Note : df1 = pd.DataFrame(np.random.randint(5,15,[250,3])).
Any suggestion for this would be appreciated. Thank you in advance

  


  import pandas as pd
import numpy as np
import ma``tplotlib.pyplot as plt
import matplotlib.animation as animation

df = data.iloc[0:250, 4:12]
df1 = df2.iloc[:,0:3]

a1 = df.iloc[:,0]/2
a2 = df.iloc[:,1]/2
b1 = df.iloc[:,2]/2
b2 = df.iloc[:,3]/2
c1 = df.iloc[:,4]/2
c2 = df.iloc[:,5]/2
m1 = df1.iloc[:,0]
m2 = df1.iloc[:,1]
m3 = df1.iloc[:,2]

fig ,ax = plt.subplots()

l1, = ax.plot (vert1, vert2, 'ro', markersize = m1[0])
l2, = ax.plot (long1, long2, 'ro', markersize = m2[0])
l3, = ax.plot (tras1, tras2, 'ro', markersize = m3[0])

def init():    
    l1.set_data([],[])
    l2.set_data([],[])
    l3.set_data([],[])
    
    return (l1,l2,l3)

def animate(i,l1,l2,l3):
    
    l1.set_data(vert1[i], vert2[i])
    l1.set_markersize(m1[i])
    l2.set_data(long1[i], long2[i])
    l2.set_markersize(m2[i])
    l3.set_data(tras1[i], tras2[i])
    l3.set_markersize(m3[i])

    return (l1,l2,l3)

Writer = animation.writers['ffmpeg']
writer = Writer(fps= 100, metadata = dict(artist = 'me'), bitrate = 1800)

ani = animation.FuncAnimation(fig, animate, fargs=(l1,l2,l3), init_func=init, interval=10, blit=False)
