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 :

FFMPEG combining 2 command to make multiple overlay [closed]
11 avril 2020, par Nano WibisonoI have two different commands and both work. but here I have a problem, how to combine these two commands into one output



the first command is to add a video overlay



ffmpeg -i final.mp4 -vf "movie=LOGO.mov, scale=100: -1 [inner]; [in][inner] overlay =10: 10 [out] " completed.mp4



the second command is to add a text overlay



ffmpeg -i final.mp4 -vf drawtext="fontfile=C\\:/Windows/Fonts/arial.ttf:fontsize=20: fontcolor=red:x=10:y=50:text='test tect'" completedtextGB.mp4



I was wondering is it possible to combine these into the 1 command ?



Thanks
Nano

Audio async after using setpts, converting to ts and concatenating
11 janvier 2018, par Aurelius SchnitzlerI am using f.i.
ffmpeg -y -ss 00:00:09.664 -t 00:00:06.939 -i "test.mp4" -an -c:v libx264 -filter:v "setpts=0.1*PTS" test2.mp4to speed up a video by 10.
But there is still audio in it when being used with
ffmpeg -y -i test2.mp4 -c copy -bsf:v h264_mp4toannexb -f mpegts 2f.tsand
ffmpeg -y -i "concat:2f.ts|..." -bsf:a aac_adtstoasc -movflags faststart -c copy final.mp4later on, yet every part’s audio in the final video is async.
In some videos added with concat the video is not sped up, ie no
-filter:v "setpts=0.1*PTS"and the audio is kept, ie no-anas inffmpeg -y -ss 1 -t 2 -i "test3.mp4" -an -c:v libx264 test4.mp4
ffmpeg -y -i test4.mp4 -c copy -bsf:v h264_mp4toannexb -f mpegts 4f.tsHow do I mute the sped up parts and have audio not be async in the final video ?
