Error trying to load ffmpeg library in dart
24 juillet 2021, par Vinícius PereiraI'm a new programmer in de Dart world and I'm trying some stuff to learn more.
I'm trying to create a application that outputs audio from a file. I checked pub and I haven't found anything that suits my needs. So I found about dart:ffi and about ffmpeg capabilities.


For the past few days I'm trying to load the ffmpeg libraries (avcodec, avformat, etc.) into my code but I haven't succeded.


This is my code.


var libraryPath = path.join(Directory.current.path, 'bin', 'avcodec.dll');
final dylib = ffi.DynamicLibrary.open(libraryPath);



This is the error I got :


Exception has occurred.
ArgumentError (Invalid argument(s): Failed to load dynamic library 'C:\Users\[MYUSER]\Documents\Code\Dart\ffmpeg\bin\avcodec.dll': 126)



What I've tried so far :


- 

- Checked the path, it's right ;
- Tried to import another library (sqlite3) with success ;
- Tried to compile the DLLs myself and also tried prebuilt ones (from the links on ffmpeg site)








My dart version
Dart SDK version: 2.13.4 (stable) on "windows_x64"


Whats the procedure to properly use the ffmpeg library with dart ?

ffmpeg with m3u8 : video and audio not synchronized
3 avril 2017, par lemelI noticed while using ffmpeg to download m3u8 streaming playlist, I get sometimes faster video.
If the content of the url master.m3u8 is the following :#EXTM3U
#EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=620941,RESOLUTION=640x352,CODECS="avc1.4d401f,mp4a.40.2"
https://hello/world.m3u8If I’m not mistaken, ffmpeg should be able to decode the EXT-X-STREAM-INF information and assign the default value while downloading.
But when I run the following command :ffmpeg -i "https://hello/darkness/my/old/friend/master.m3u8" -c copy "Some Video File.ts"
I get a video that is faster than the Audio.
If I run this command without the -c copy :ffmpeg -i "https://hello/darkness/my/old/friend/master.m3u8" "Some Video File.ts"
I get a video and audio synchronized. But the video quality is worse.
What’s the problem ?
