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 ?

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
