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.

Everytime I run my code ffmpeg responds with this instead of doing its function. How do I fix ?

Everytime I run the code it does this.


code :

 main()



Anyone got any idea why this happens ?


I'm making a script that scrapes videos from a specific subreddit.


Also if it helps the temp video file is corrupted when it gets made.


I've put this into chatGPT as well and brought an expert friend and he hasn't been able to help me.

The latest ffmpeg shows "get_buffer() failed". Is this a bug ?
20 juin 2023, par Ryanffmpeg version 2023-06-19-git-1617d1a752-full_build-www.gyan.dev


i7-1255U, Windows 11


The command line is


"ffmpeg.exe" -y -hwaccel qsv -ss 00:00:03.461 -to 00:00:12.009 -i "input.mov" -c:v h264_qsv -global_quality 25 -look_ahead 1 -preset veryslow -c:a aac -ar 48000 -ac 2 -ab 128k output.mp4



The "input.mov" is mjpeg.


The result is :


[mjpeg_qsv @ 0000019930260080] get_buffer() failed
[vist#0:0/mjpeg @ 000001993025ff00] Error submitting packet to decoder: Cannot allocate memory

[vist#0:0/mjpeg @ 000001993025ff00] Error submitting packet to decoder: Cannot allocate memory



The messages above repeats many many many times. Finally, it shows :


[vist#0:0/mjpeg @ 000001993025ff00] Error submitting EOF to decoder: Cannot allocate memory



I tried the same command line on a very old version, and it works fine. Is this a bug or there is something new that comes with the new version ?


Thank you for your help.
