Cela permet, par exemple : de pouvoir partager les frais de mise en œuvre entre plusieurs projets / individus ; de pouvoir déployer rapidement une multitude de sites uniques ; d’éviter d’avoir à mettre l’ensemble des créations dans un fourre-tout numérique comme c’est le cas pour les grandes plate-formes tout public disséminées sur le (...)

FFmpeg 6.0 won't work because the header files can't connect or interact with each other. How do I fix the files ?
11 septembre 2023, par Señor TontoI am creating a win32 API C++ application with Microsoft Visual Studio 2022 in a .sln file. I've got quite far in basic functionalities & decided to try out video decoding & playing ; I've practiced this before but not with C++. So, I looked to see good libraries & found FFmpeg. Of course, I thought this would be quite straightforward - just import the headers & code, right ? No. Firstly, the FFmpeg I'm using is one of the pre-built binaries. The 'ffmpeg-master-latest-win64-gpl-shared.zip' From the BtbN Github repository. I decompressed it with WinRar & placed the files in Program Files (x86). Later on, I realised my mistake of placing it with 32-bit programs since it's a 64-bit build. So I transferred it to Program Files. Even after this though my issue persists. The issue being that the .h files of FFmpeg cannot communicate with each other. For some reason, they can't navigate to where the header files are. I am quite sure the reason for this may have something to do with where I save the files, the directory. Nowhere on the FFmpeg website can I see where you're expected to have the file directory at. I am sure there's a preset file path that is expected. Maybe I've named the FFmpeg folder incorrectly ? Or maybe it's not meant to go in Program Files ? The current directory for the FFmpeg folder for me is : C :\Program Files\FFmpeg. Below I will provide pictures of the errors I get where the code can't connect to other .h files as well as the file path. I'll also provide my code.

I severely doubt my code has anything to do with the issue though. It's probably directory-based. I just placed wWinmain here to keep with the character limit.

FFmpegKit : "Operation not permitted" in many android devices [closed]
26 août 2023, par MrmI'm using FFmpegKit 5.1.LTS in my application. A lot of my users have reported that they cannot edit videos (10%). When I tried to obtain their logs, I noticed that many of them are encountering an 'Operation not permitted' error. My users have granted all the necessary storage permissions (READ_EXTERNAL_STORAGE, WRITE_EXTERNAL_STORAGE).


Here is an example :


User device :

doc/html : support texinfo 7.0
8 novembre 2023, par Frank Plowmandoc/html : support texinfo 7.0
Resolves trac ticket #10636 (http://trac.ffmpeg.org/ticket/10636).
Texinfo 7.0, released in November 2022, changed the names of various
functions. Compiling docs with Texinfo 7.0 resulted in warnings and
improperly formatted documentation. More old names appear to have
been removed in Texinfo 7.1, released October 2023, which causes docs
compilation to fail.This commit addresses the issue by adding logic to switch between the old
and new function names depending on the Texinfo version. Texinfo 6.8
produces identical documentation before and after the patch.CC
