MoviePy error : failed to read the first frame of video file ****. That might mean that the file is corrupted
14 juillet 2022, par Udit Hari VashishtI am trying to reverse a video using MoviePy. My code is as under : -


from moviepy.editor import VideoFileClip
from moviepy.video.fx.all import time_mirror

clip = VideoFileClip("udit.mp4")

clip = clip.fx(time_mirror)

clip.write_videofile("reversed.mp4")


But, when I run it I get the following error :-

OSError: MoviePy error: failed to read the first frame of video file udit.mp4. That might mean that the file is corrupted. That may also mean that you are using a deprecated version of FFMPEG. On Ubuntu/Debian for instance the version in the repos is deprecated. Please update to a recent version from the website

I have tried the code on both Mac and Windows PC. The other functionality of MoviePy works fine, but I am not able to reverse the video. Both of my systems have ImageMagick and FFMPEG installed.

ffmpeg - merge multiple audio file with the single video file at specific time
2 septembre 2021, par Dishant MewadaI have multiple audio files speech_01.mp3, speech_02.mp3 etc. with 5 seconds duration. I want to merge these audio files with a single video file (video.mp4), at every 6 seconds step.


I have tried


ffmpeg -y -i video.mp4 -itsoffset 6 -i speech_01.mp3 -itsoffset 12 -i speech_02.mp3 -filter_complex amix -map 0:v -map 1:a -map 2:a -c:v copy -async 1 -c:a aac -strict experimental output.mp4


For some reason, this method only merges the first audio file.


Thanks.
