  • Script d’installation automatique de MediaSPIP

    25 avril 2011, par

    Afin de palier aux difficultés d’installation dues principalement aux dépendances logicielles coté serveur, un script d’installation "tout en un" en bash a été créé afin de faciliter cette étape sur un serveur doté d’une distribution Linux compatible.
    Vous devez bénéficier d’un accès SSH à votre serveur et d’un compte "root" afin de l’utiliser, ce qui permettra d’installer les dépendances. Contactez votre hébergeur si vous ne disposez pas de cela.

  • How to transcode 50 H264 Streams with FFMPEG more efficient ?

    20 juin 2019, par Kevin

    i need to (Re-)Transcode 50 Live-Streams. These streams are in H264 with 720p to 1080p and bitrates up to 10M. I just want to reduce the quality and bitrate of the streams to up to 720p with max. 2M Bitrate.

    That’s what i’m doing right now :

    ffmpeg -re -i "http://domain.tld/path/file.ext" -vcodec libx264 -preset veryfast -vf scale=-2:720 -b:v 2M -maxrate 2M -bufsize 1M -acodec libfdk_aac -f flv "rtmp://127.0.0.1:1935/live/stream_xyz"

    My Server CPU (2 x Xeon E5-2630 v3) is already at 100% with just 12 streams. I will upgrade my server to 2 x Xeon Gold 5118 next month, but i don’t think, that this will give me that much more power.

    Can someone help me, to do this more efficient ?

    Would it be more efficient / cheaper to do this with GPUs ?

    Or any other ideas, to do that as efficient and cheap as possible ?

    Thanks

  • Boto3 Video Upload 0 Bytes from Heroku

    14 juillet 2017, par genghiskhan

    I have a small Flask api that takes a video and an image, overlays the image on the video and uploads the result to Amazon S3. I am using ffmpeg to do the actual overlaying. Here is that code :

    command = "ffmpeg -i {0} -i {1} -filter_complex \"overlay=0:0\" {2}".format(background_name, overlay_name, output_name)
    
subprocess.getoutput(command)

    Then I simply upload it via Boto3 :

    s3.upload_file(output_name, VIDEO_BUCKET_NAME, output_name)

    This code works fine when I run on localhost ; however, when I test in while deployed to Heroku, it always uploads a file with 0 bytes. I suspect that it may be a problem with Heroku’s transient filesystem, but the file is being used immediately after it is created.

  • Execute ffmpeg in AWS ec2 instance windows

    15 janvier 2016, par Napster

    Im trying to execute ffmpeg command on amazon’s windows ec2 instance using elastic beanstalk.
    I intend to merge multiple videos into a single video using a .net application.

    I cant see the file being created in the folder, so cant confirm if ffmpeg is working. The merging is working perfectly on local deployment and i can view the merged video.
    I have configured my deployment for the required permission of file creation rights (.ebextensions) and it is working.

    Im not sure what i need to do to allow execution of ffmpeg command, and im stuck here. Ive been through the forum and found similar links related to linux but not windows.

    Being a newbie im really not sure how to proceed.
    Are there any permission/steps i need to perform to allow ffmpeg command to execute on ec2 instance. If any ? please share.
