Les vidéos
21 avril 2011, parComme les documents de type "audio", Mediaspip affiche dans la mesure du possible les vidéos grâce à la balise html5 .
Un des inconvénients de cette balise est qu’elle n’est pas reconnue correctement par certains navigateurs (Internet Explorer pour ne pas le nommer) et que chaque navigateur ne gère en natif que certains formats de vidéos.
Son avantage principal quant à lui est de bénéficier de la prise en charge native de vidéos dans les navigateur et donc de se passer de l’utilisation de Flash et (...)

Using ffmpeg via Popen running extremely slow in python
30 décembre 2016, par lawI’m writing a script that batch processes video in python. Basically, it takes a .dv file turns it into .avi and the captures only the audio in .wav format. Command line use of ffmpeg on a mac terminal executes on the order of a second or so. But when I use Popen to run the same code from within python, each file takes multiple minutes. Not sure why...I think I may be using Popen inappropriately. Code listed below :
command1 = ['ffmpeg', '-i', input_name, '-y', '-vcodec', 'h264', 'temp.avi']
command2 = ['ffmpeg', '-i', 'temp.avi', '-ab', '160k', '-ac', '44100', '-vn', outfile]
proc1 = subprocess.Popen(command1, stdin=subprocess.PIPE, stderr=subprocess.PIPE)
proc1.communicate()
print "Converted to avi"
proc2 = subprocess.Popen(command2, stdin=subprocess.PIPE, stderr=subprocess.PIPE)
proc2.communicate()
print "Wavefile extracted" -
FFMPEG in Python Returns Corrupted Video
11 décembre 2020, par user14210589In Python, I run ffmpeg to convert a video to a .mp4 file. However, for some reason, the video it creates is not compatible with anything (I'm pretty sure it's corrupted). The code looks like this :


import os

os.system("ffmpeg -i Images/i1.mov Images/edited.mp4 -loglevel quiet")
os.remove("Images/i1.mov")
os.rename("Images/edited.mp4", "Images/i1.mp4")



However, the video file created doesn't play.
I am getting an error that just says
killed
. What am I doing wrong ?

Edit : I also tried converting to .WebM rather than .mp4, and it had no effect. (it still gave the same error)
