FFmpegKit : "Operation not permitted" in many android devices [closed]
26 août 2023, par MrmI'm using FFmpegKit 5.1.LTS in my application. A lot of my users have reported that they cannot edit videos (10%). When I tried to obtain their logs, I noticed that many of them are encountering an 'Operation not permitted' error. My users have granted all the necessary storage permissions (READ_EXTERNAL_STORAGE, WRITE_EXTERNAL_STORAGE).


Here is an example :


User device :


Manufacturer : Sony

Model : SOG05

ABI : [arm64-v8a, armeabi-v7a, armeabi]

Android SDK : 33

Command :

ffmpeg -y -ss 12.789 -to 32.654 -i "/storage/emulated/0/Movies/lts/lts_20230824_100739.mp4" -filter_complex "[0:v:0] scale=1080:2520,setsar=1/1[v0];[0:a:0]atempo=1.0,volume=1.0[a0]; [v0] [a0] concat=n=1:v=1:a=1[conv][cona];[conv] drawtext=fontfile=/system/fonts/Roboto-Regular.ttf:text=lts edit:x=(w-text_w-69.55932):y=(h-text_h-36.61017):fontsize=84:fontcolor=white:shadowcolor=black:shadowx=5.4915257:shadowy=5.4915257[conv]" -map "[conv]" -map "[cona]" -c:v libx264 -force_key_frames 'expr:gte(t,n_forced*1)' -preset ultrafast -r 30 -shortest /storage/emulated/0/Movies/lts/lts_20230826_092915_edited.mp4

FFmpeg 6.0 won't work because the header files can't connect or interact with each other. How do I fix the files ?
11 septembre 2023, par Señor TontoI am creating a win32 API C++ application with Microsoft Visual Studio 2022 in a .sln file. I've got quite far in basic functionalities & decided to try out video decoding & playing ; I've practiced this before but not with C++. So, I looked to see good libraries & found FFmpeg. Of course, I thought this would be quite straightforward - just import the headers & code, right ? No. Firstly, the FFmpeg I'm using is one of the pre-built binaries. The 'ffmpeg-master-latest-win64-gpl-shared.zip' From the BtbN Github repository. I decompressed it with WinRar & placed the files in Program Files (x86). Later on, I realised my mistake of placing it with 32-bit programs since it's a 64-bit build. So I transferred it to Program Files. Even after this though my issue persists. The issue being that the .h files of FFmpeg cannot communicate with each other. For some reason, they can't navigate to where the header files are. I am quite sure the reason for this may have something to do with where I save the files, the directory. Nowhere on the FFmpeg website can I see where you're expected to have the file directory at. I am sure there's a preset file path that is expected. Maybe I've named the FFmpeg folder incorrectly ? Or maybe it's not meant to go in Program Files ? The current directory for the FFmpeg folder for me is : C :\Program Files\FFmpeg. Below I will provide pictures of the errors I get where the code can't connect to other .h files as well as the file path. I'll also provide my code.

How to save srt file with a video to be part of the video ?
14 septembre 2023, par abdallah mostafaI've an application that generate srt file for a video with AI but I want to save the video to user's storage with the srt subtitle burned on the video not just embedded.


this is the response form the API


"fotmated_subtitle": [
 {
 "display_text": "You know those cat are memes that everybody uses in their videos and the TV movie clips that people use.",
 "interval": [
 "0:00:00.000",
 "0:00:04.000"
 ]
 },
 {
 "display_text": "Well, who are the four best free websites to find a move?",
 "interval": [
 "0:00:04.000",
 "0:00:06.240"
 ]
 }
 ]


I could add this as a widget over the video that would change accourding to intervals.
I want to know How to save that video with the subtitle


Future<void> saveSubtitle() async {
 emit(ExportSubtitleLoading());
 String subtitleFilter = "";
 for (var subtitle in subtitles!.fotmatedSubtitle!) {
 String startTime = subtitle.interval![0];
 String endTime = subtitle.interval![1];
 String text = subtitle.displayText!;
 subtitleFilter +=
 "drawtext=text='$text':enable='between(t,$startTime,$endTime)':x=(w-text_w)/2:y=h-30:fontsize=24:fontcolor=white,";
 }

 final dir = await getTemporaryDirectory();
 String outputPath = '${dir.path}/ex_vid.mp4';
 final arguments = [
 '-i',
 inputFile,
 '-vf',
 subtitleFilter,
 '-c:v',
 'libx264',
 '-c:a',
 'copy',
 outputPath
 ];
 (arguments.join(' ')).logger;
 '=============='.logger;
 await FFmpegKit.execute(arguments.join(' ')).then((session) async {
 final returnCode = await session.getReturnCode();

 if (ReturnCode.isSuccess(returnCode)) {
 ('The Converstion is Success').logger;
 emit(ExportSubtitleSuccess());
 } else if (ReturnCode.isCancel(returnCode)) {
 // CANCEL
 ('The Converstion is Cancelled').logger;
 } else {
 emit(ExportSubtitleerror());
 ('The Converstion Have an Error').logger;
 }
 });
 }
</void>

I've tested this method but still does not worked


here is the full command


String command =
 "-y -i /data/user/0/com.amaa.aistudio/cache/file_picker/Blink-96bdc94a-17df-4f64-b560-90811a44c4f8-Original.mp4 -vf \"drawtext=text='You know those cat are memes that everybody uses in their videos and the TV movie clips that people use.':enable='between(t,0,4.000)':x=(w-text_w)/2:y=h-30:fontsize=24:fontcolor=white,drawtext=text='Well, who are the four best free websites to find a move?':enable='between(t,4.000,6.240)':x=(w-text_w)/2:y=h-30:fontsize=24:fontcolor=white\" -c:v libx264 -c:a copy /data/user/0/com.amaa.aistudio/cache/ex_vid.mp4";
