Can't convert video with cuda after updating ffmpeg
8 avril 2024, par Peppei've used this command sometimes to convert 4k video into 1080p without problem with tool "ffmpeg batch" and ffmpeg 5.1 ? "2022-08-10-git-8fc7f0fdec-full_build-www.gyan.dev Copyright (c) 2000-2022 the FFmpeg developers built with gcc 12.1.0 (Rev2, Built by MSYS2 project)" :



-map 0 -map -0:t -filter_complex "scale_cuda=1920:1080:format=yuv420p:interp_algo=lanczos,hwdownload" -fps_mode:v passthrough -c:v h264_nvenc -preset 18 -profile:v high -level 4.1 -b:v 13000K -rc cbr -c:a copy -c:s copy


this with pre-input "-hwaccell cuvid"


Now if i try to to the same with latest version of ffmpeg (6.1.1) it don't work. I've tried to change the pre-input with "-hwaccel cuda" but still nothing, it give me error "Cannot find a matching stream for unlabeled input pad scale_cuda:default".


If i try to add [v:0] before 'scale_cuda', i get this error (pgs subs error was present also before editing command) :

Can someone tell me the correct way to do it now with an rtx 4090 ?

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");
 }

ffmpeg trouble with NetMaui and Android [closed]
15 juin 2024, par Billy VanegasI find myself in a following predicament. While I work with Visual Studio 2022, ffmpeg performs flawlessly on Windows platform. However, I'm encountering difficulties when attempting to replicate this functionality on Android. Despite exploring NuGet packages like FFMpegCore, which seem to be ffmpeg wrappers but lack ffmpeg itself, I'm still struggling to find a clear path forward. I've even tried integrating ffmpeg-kit for Android as per the instructions, only to face repeated failures and a sense of confusion. I must admit my puzzlement : why isn't there a straightforward method to seamlessly add ffmpeg to a .NET MAUI project that functions consistently across both iOS and Android platforms ?


I want to convert MP3 files to WAV format using FFmpeg on the Android platform within a .NET MAUI project.


I am using the FFmpegCore library and have downloaded the FFmpeg binaries from the official FFmpeg website. However, I encountered issues when attempting to pass the binary folder on the emulator, when I try to pass it, I get
permission deniedin working folder :
/data/user/0/com.companyname.projectname/files/ffmpegon this part of code :

await FFMpegArguments

 .OutputToFile(wavPath, true, options => options
 .WithAudioCodec("pcm_s16le")
 .WithAudioSamplingRate(44100)
 .WithAudioBitrate(320000)
 )
 .ProcessAsynchronously();
