La sauvegarde automatique de canaux SPIP
1er avril 2010, parDans le cadre de la mise en place d’une plateforme ouverte, il est important pour les hébergeurs de pouvoir disposer de sauvegardes assez régulières pour parer à tout problème éventuel.
Pour réaliser cette tâche on se base sur deux plugins SPIP : Saveauto qui permet une sauvegarde régulière de la base de donnée sous la forme d’un dump mysql (utilisable dans phpmyadmin) mes_fichiers_2 qui permet de réaliser une archive au format zip des données importantes du site (les documents, les éléments (...) -

FFMPEG Flutter : attaching captions to a video issue
24 juillet 2024, par Aqib JavedI am working on an app where i first extract audio from a video, then transcribe it and then i wanna attach that transcribed captions or subtitles to the original video.


Everything is working smooth except the subtitles attaching part
if im running the FFMPEG command directly in terminal, it works fine but not in flutter


here is my code of attaching the subtitles to the video :


Future<void> attachCaptionsToVideo(DeepGramResponse deepGramResponse) async {
 var tempDir = await getTemporaryDirectory();

 final outputPath = "${tempDir.path}/outputWithCaptions.mp4";
 final String subtitlePath = deepGramResponse.captionsPath
 .replaceAll('\\', '\\\\')
 .replaceAll(' ', '\\ ');
 final String command =
 '-y -i ${deepGramResponse.videoPath} -vf subtitles=$subtitlePath $outputPath';
 await FFmpegKit.executeAsync(command, (session) async {
 final returnCode = await session.getReturnCode();
 final output = await session.getOutput();
 final error = await session.getFailStackTrace();

 log('FFmpeg command executed with return code: $returnCode');
 if (ReturnCode.isSuccess(returnCode)) {
 log('Captions attached successfully');
 deepGramResponse.copyWith(
 videoPath: outputPath,
 );
 Get.to(() => VideoPlayerScreen(videoPath: outputPath));
 } else {
 log('FFmpeg command failed');
 log('Error output: $output');
 log('Error details: $error');
 Fluttertoast.showToast(
 msg: 'Something went wrong, please try again later');
 }
 });
 }
</void>

here is the error im getting :




[AVFilterGraph @ 0x7b8a3f35f0] No option name near
'/data/user/0/com.example.blink/app_flutter/captions.srt'
[AVFilterGraph @ 0x7b8a3f35f0] Error parsing a filter description around :

Overlaying video with ffmpeg
11 novembre 2012, par eleeI'm attempting to write a script that will merge 2 separate video files into 1 wider one, in which both videos play back simultaneously. I have it mostly figured out, but when I view the final output, the video that I'm overlaying is extremely slow.
Here's what I'm doing :
-
Expand the left video to the final video dimensions
ffmpeg -i left.avi -vf "pad=640:240:0:0:black" left_wide.avi
-
Overlay the right video on top of the left one
ffmpeg -i left_wide.avi -vf "movie=right.avi [mv] ; [in][mv] overlay=320:0" combined_video.avi
In the resulting video, the playback on the right video is about half the speed of the left video. Any idea how I can get these files to sync up ?

FFMPEG not creating thumbnails
12 juin 2016, par MixedVegMy ffmpeg command in php is
echo $cmd_thumbnail_create = ("\"$ffmpeg\" -i \"" . $dir.$videopath . "\" -an -ss $getFromSecond \"" . $dir.$thumbnailpath ."\"");
exec($cmd_thumbnail_create);Output of which is
"C :\FFMPEG\bin\ffmpeg" -i "C :/xampp/htdocs/final/uploaded_videos/intro_en.mp4" -an -ss 6 "C :/xampp/htdocs/final/thumbnail/intro_en.jpg"
This when copied and executed on the command prompt creates the thumbnail at proper location with proper name.
Any suggestions ?
