Déploiements possibles
31 janvier 2010, parDeux types de déploiements sont envisageable dépendant de deux aspects : La méthode d’installation envisagée (en standalone ou en ferme) ; Le nombre d’encodages journaliers et la fréquentation envisagés ;
L’encodage de vidéos est un processus lourd consommant énormément de ressources système (CPU et RAM), il est nécessaire de prendre tout cela en considération. Ce système n’est donc possible que sur un ou plusieurs serveurs dédiés.

File conversion to mp3 returning failure everytime using flutter package ffmpeg_kit_flutter
6 novembre 2024, par Sanath baltharI am trying to convert a .wav audio file generated from a flutter's text to speech package - "flutter_tts" to mp3 file but it is failing everytime.
I have written the below code for file conversion. I have imported the package ffmpeg_kit_flutter. It doesnt even show why the conversion is failing.
I have looked up in stackoverflow and other sites but could not find any relevant solutions. I am using vscode as editor. I have attached flutter doctor output below as well. Could anyone please guide me ? Let me know if you need more information.


List<string> command = [
 '-i', '$filePath/998tts.wav',
 '-c:a', 'mp3',
 '$filePath/998.mp3'
 ];

 await FFmpegKitConfig.enableLogs();
 FFmpegKitConfig.enableLogCallback((log) =>print('FFmpeg log: $log')); 
 FFmpegSession result = await FFmpegKit.executeWithArguments(command);
 dynamic resultcode = await result.getReturnCode();
 dynamic resultlogs = await result.getLogsAsString();
 // FFmpegKitConfig.setLogLevel(logLevel)
 if(ReturnCode.isSuccess(resultcode)){
 print("file saved after conversion at $filePath/998.mp3 and result : Success and logs : $resultlogs");
 }
 else{
 print("Result : failure and logs : $resultlogs");
 }

Building FFMPEG for Visual Studio development
28 juillet 2016, par gboyI’m trying to use ffmpeg in Visual Studio 2013 C++ software (ultimately as part of an OpenCV project) - but right now I’m just trying to get basic FFMPEG functionality. In general, when building in Visual Studio, I build 64—bit software with Multi-threaded DLL runtime libraries. I have built ffmpeg using the general instructions for ’Native Windows compilation using ... MinGW-w64’ at http://ffmpeg.org/platform.html#Windows (I provide a more detailed set of steps I followed below...).
After building the ffmpeg software on my system, I tried to create a simple ’hello world’ project in Visual Studio 2013. Specifically, I tried to implement the initial tutorial file presented at http://dranger.com/ffmpeg/tutorial01.html. Upon building the project, I get the error :
c :\msys64\usr\local\ffmpeg\libavutil\common.h(45) : fatal error C1083 : Cannot
open include file : ’libavutil/avconfig.h’ : No such file or directoryThe following are the detailed steps I took to build ffmpeg and create my basic Visual Studio project :
============ Building ffmpeg ===============
- Downloaded and intalled msys2-x86_64-20160205.exe from http://msys2.github.io
- Ran
update-core
to update the Msys2 install - Ran
pacman -Suu
(twice) to complete the update (following the instructions about updating shortcuts, etc.) - Then I quit out of the MSys2 shell and opened the MinGW-w64 Win64 Shell. In this new shell :
- Installed the following packages using
pacman -S
The list of packages I installed is : make, pkg-config, diffutils, mingw-w64-x86_64-yasm, mingw-w64-x86_64-gcc, mingw-w64-x86_64-SDL, git - Then I cd’d into
cd /usr/local
- Ran
git clone https://git.ffmpeg.org/ffmpeg.git ffmpeg
- I wanted to build the ffmpeg library ’out-of-tree’ of this MSys64 folder. So, in the regular file system of my Windows machine I created a folder at C :\ffmpeg
- Back in the Win64 Shell, I cd’d to this new folder :
cd /c/ffmpeg
- Then ran
/usr/loca/ffmpeg/configure --enable-shared
- Then
make -r
- And, finally
make install
Now, if I had to guess, my ’flaw’ was in the options I used when calling the ’configure’ script of ffmpeg. Do I need to use particular options so that I can take the ffmpeg libraries built here and use them as dynamic (DLL) libraries in Visual Studio ?
========== Configuring my Visual Studio Project ============
Here’s how I created a simple hello world project in Visual Studio to see if ffmpeg is working.
- I created a new Visual C++ ’Empty Project’ in Visual Studio 2013
-
I then configured the project properties as follows :
a. In C/C++ => General => Additional Include Directories, I put
C :\msys64\usr\local\ffmpeg
b. In Linker=>General => Additional Library Directories, I pointed to each of the built library folders (basically I pointed at all of the libraries that were built to ensure I was not inadvertently missing the critical one). The list is as follows :
- C :\ffmpeg\libavcodec
- C :\ffmpeg\libavdevice
- C :\ffmpeg\libavfilter
- C :\ffmpeg\libavformat
- C :\ffmpeg\libavutil
- C :\ffmpeg\libswresample
- C :\ffmpeg\libswscale
- C :\ffmpeg
c. In Linker=> Input => Additional Dependencies, I pointed to the particular libraries (again - I pointed to all of the ones present). The list is :
- avcodec.lib
- avdevice.lib
- avfilter.lib
- avformat.lib
- avutil.lib
- swresample.lib
- swscale.lib
-
I then created a new source file called ’tut01.c’ and copied/pasted the code from http://dranger.com/ffmpeg/tutorial01.c
- Then hit F7 and got the error specified above about not finding avconfig.h
The above is my best guess as to the steps I need to follow to get this working in Windows (btw, it’s Windows 10, 64-bit) & Microsoft Visual Studio 2013. What should I change to get this basic program to build and run ?

Change AVI creation date with ffmpeg ?
1er novembre 2016, par brockAs far as I can tell the following ffmpeg command should copy all existing metadata in the input file to the output file and modify the specified field in the output file :
ffmpeg -i VID_20130502_220104.avi -metadata creation_time="2013-05-02 22:01:04" -codec copy VID_20130502_220104-2.avi
Instead, it seems to strip all metadata from the output file. Here is the output of a few commands. I am going nuts. I think this should work, but why is it not ?
Command to edit the creation time :
ffmpeg -i VID_20130502_220104.avi -metadata creation_time="2013-05-02 22:01:04" -codec copy VID_20130502_220104-2.avi
