  • Whats the difference between stream generated by ffmpeg vs lib VLC

    20 janvier 2015, par Arif Ali Saiyed

    I am trying to stream a Mp4 file to a webm file.

    After that I am reading this file chunk by chunk and feeding it to HTML5 viewer
    (video tag of html 5 viewer)

    in order to stream from MP4 file webm file I have had three options

    1) Stream out using VLC media player application
    2) Stream using libVLC through C code
    How to stream video using C/C++
    3) stream using ffmpeg commandline
    ffmpeg -i test.mp4 -c:v libvpx -c:a libvorbis -pix_fmt yuv420p -quality good output.webm

    While comsuming this webm generataed by all three options. 1st and 2nd is not working. While 3rd one is working. 1st and 2nd works only after streaming to file is completed and when last chunk of output file is fed to html5 video player.

    It seems vlcplayer and libVLC is not generating the required fragments with keyframes that are generated by ffmpeg.

    Is there anyway we can instruct libVLC or VLCplayer also to generated fragments with keydrame info ?

  • Difference between clip.to_videofile and clip.write_videofile

    10 décembre 2014, par Ruchir

    what is the difference between clip.to_videofile and clip.write_videofile ?

    Do they have any effect on the frames of a CompositeVideoClip ?

    i wrote a code :

    video=CompositeVideoClip([clip1,clip2.set_start(dur)] 
    
video.write_videofile("video.mp4",fps=clip1.fps) # or video.to_videofile("video.mp4",fps=clip1.fps)
    
clip=VideoFileClip("video.mp4")
    
video.save_frame("frame1.png")
    
clip.save_frame("frame2.png") 
    
from PIL import Image
    
import numpy as np
    
im1=Image.open("frame1.png")
    
image1=np.asarray(im1)
    
im2=Image.open("frame2.png")
    
image2=np.asarray(im2)

    when i compared the two arrays image1 and image2, they were not the same...Can anyone explain me why does this happen ? and what do i do if i have keep the frame from getting changed when i write a composite clip into a video ?
