Automated installation script of MediaSPIP
25 avril 2011, parTo overcome the difficulties mainly due to the installation of server side software dependencies, an "all-in-one" installation script written in bash was created to facilitate this step on a server with a compatible Linux distribution.
You must have access to your server via SSH and a root account to use it, which will install the dependencies. Contact your provider if you do not have that.
The documentation of the use of this installation script is available here.

Dash output with ffmpeg not producing durations specified with -seg_duration
30 juillet 2022, par CodieThere is a .mp4 file of 35 MB and 51 seconds. I have to create 51 chunks, each corresponding to 1 second with a size of less than 1MB (the total size should be almost the same as the original file). Please note that I have to implement lossless converting.


I've tried many times, but it just produces about 10 files above 10 MB.



Command :


ffmpeg -re -i input.mp4 -map 0:v -c:v libx264 -crf 0 -bf 1 -keyint_min 120 -g 120 -sc_threshold 0 -b_strategy 0 -use_template 1 -seg_duration 1 -window_size 60 -adaptation_sets "id=0,streams=v id=1,streams=a" -f dash ./dashTest/out.mpd

ffmpeg tcp error -138 and HTTP error 503 while downloading from https source
15 juin 2022, par PeterMi'm trying to download media (video) files from sharepoint (i have view access), but during the process i get several "Connection to tcp ://xxx.xxxxx.ms:443 failed : Error number -138 occurred" or "HTTP error 503 Service Unavailable" errors






i get more errors with the following parameters :


ffmpeg -i "https://theURLtoTheManifestYouCopiedHere" -codec copy downloadedVideo.mp4


less errors with :


ffmpeg -re -vsync 1 -i "https://theURLtoTheManifestYouCopiedHere" -codec copy downloadedVideo.mp4


the options suggested in this article didn't help : https://medium.com/intrasonics/robust-continuous-audio-recording-c1948895bb49


the output video is ok, but sound seems to be missing occasionally (a few seconds worth)


ffmpeg version 2022-06-12-git-4d45f5acbd-essentials_build-www.gyan.dev


any advice ?
