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-lambda on net-core
19 avril 2022, par user1765862I have a amazon lambda function which needs to use ffmpeg library.
I've found various examples on using ffmpeg lambda layer with nodejs runtime like this one
https://github.com/serverlesspub/ffmpeg-aws-lambda-layer but I would rather use .net core as runtime for my function instead of nodejs.


Any suggestions ?

why ffmpeg starts many processes
29 octobre 2020, par jamesI have a doubt about the functioning of the ffmpeg program, I noticed that after starting the program on a 4gb memory raspberry pi4 many processes are started, is it normal or is there something wrong with my program ? I remember that on an amazon ec2 instance by controlling with htop only one process was created


Code I used


from subprocess import Popen

ffmpeg_process = Popen(["ffmpeg", "-hide_banner", "-loglevel", "panic", "-y", "-i", "./video/video1.mp4",
 "-vcodec", "h264", "-acodec", "mp3", "./video/video2.mp4"],
 start_new_session=True)

ffmpeg_process.wait()

Passing python's file like object to ffmpeg via subprocess
3 juillet 2012, par tejinderssI have a django FileField, which i use to store wav files on the Amazon s3 server. I have set up the celery task to read that file and convert it to mp3 and store it to another FileField. Problem i am facing is that i am unable to pass the input file to ffmpeg as the file is not the physical file on the hard disk drive. To circumvent that, i used stdin to feed the input stream of the file with the django's filefield. Here is the example :
output_file = NamedTemporaryFile(suffix='.mp3')
subprocess.call(['ffmpeg', '-y', '-i', '-', output_file.name], stdin=recording_wav)where recording_wav file is : , which is actually stored on the amazon s3 server.
The error for the above subprocess call is :AttributeError: 'cStringIO.StringO' object has no attribute 'fileno'
How can i do this ? Thanks in advance for the help.
