Transcoding with custom commands using streamio-ffmpeg
14 avril 2017, par ACIDSTEALTHI’m trying to transcode a video file using
streamio-ffmpegwith some custom commands, but nothing I try seems to work. I want to transcode the video with the following options :ffmpeg -i input.mp4 -vf
"format=yuv444p,
drawbox=y=ih/PHI:color=0x000000@0.4:width=iw:height=48:t=max,
drawtext=font='OpenSans-Regular,Sans':text='CUSTOM TEXT':fontcolor=0xFFFFFF:fontsize=24:x=(w-tw)/2:y=(h/PHI)+th,
format=yuv420p"
-c:v libx264 -c:a copy -movflags +faststart output.mp4I’ve tried the following code combinations without success :
-
Tried removing the line breaks and converting the command string to an array, following the instructions in the docs.
video = FFMPEG::Movie.new('input.mp4')
opts = %w(ffmpeg -i input.mp4 -vf "format=yuv444p, drawbox=y=ih/PHI:color=0x000000@0.4:width=iw:height=48:t=max, drawtext=font='OpenSans-Regular,Sans':text='CUSTOM TEXT':fontcolor=0xFFFFFF:fontsize=24:x=(w-tw)/2:y=(h/PHI)+th, format=yuv420p" -c:v libx264 -c:a copy -movflags +faststart output.mp4)
video.transcode('output.mp4', opts)But this yields the error :
[NULL @ 0x7f962100e200] Unable to find a suitable output format for 'ffmpeg'
ffmpeg: Invalid argument
from /Users/ACIDSTEALTH/.gem/ruby/2.3.0/gems/streamio-ffmpeg-3.0.2/lib/ffmpeg/transcoder.rb:112:in `validate_output_file' -
Tried stripping out the input file name and output file name since the gem seems to handle that for you.
video = FFMPEG::Movie.new('input.mp4')
opts = %w(-vf "format=yuv444p, drawbox=y=ih/PHI:color=0x000000@0.4:width=iw:height=48:t=max, drawtext=font='OpenSans-Regular,Sans':text='CUSTOM TEXT':fontcolor=0xFFFFFF:fontsize=24:x=(w-tw)/2:y=(h/PHI)+th, format=yuv420p")
video.transcode('output.mp4', opts)Which returns this error :
[NULL @ 0x7fd0a9008c00] Unable to find a suitable output format for 'drawbox=y=ih/PHI:color=0x000000@0.4:width=iw:height=48:t=max,'

from /Users/ACIDSTEALTH/.gem/ruby/2.3.0/gems/streamio-ffmpeg-3.0.2/lib/ffmpeg/transcoder.rb:112:in `validate_output_file' -
Tried removing the
-vfflag and just running everything within the quotation marks.video = FFMPEG::Movie.new('input.mp4')
opts = %w(format=yuv444p, drawbox=y=ih/PHI:color=0x000000@0.4:width=iw:height=48:t=max, drawtext=font='OpenSans-Regular,Sans':text='CUSTOM TEXT':fontcolor=0xFFFFFF:fontsize=24:x=(w-tw)/2:y=(h/PHI)+th, format=yuv420p)
video.transcode('output.mp4', opts)This returns another error :
[NULL @ 0x7fab8101fe00] Unable to find a suitable output format for 'format=yuv444p,'
format=yuv444p,: Invalid argument
from /Users/ACIDSTEALTH/.gem/ruby/2.3.0/gems/streamio-ffmpeg-3.0.2/lib/ffmpeg/transcoder.rb:112:in `validate_output_file' -
Tried removing the
formatarguments since ffmpeg is clearly complaining about those.video = FFMPEG::Movie.new('input.mp4')
opts = %w("drawbox=y=ih/PHI:color=0x000000@0.4:width=iw:height=48:t=max, drawtext=font='OpenSans-Regular,Sans':text='CUSTOM TEXT':fontcolor=0xFFFFFF:fontsize=24:x=(w-tw)/2:y=(h/PHI)+th")
video.transcode('output.mp4', opts)Again another error :
[NULL @ 0x7fc7f880a800] Unable to find a suitable output format for 'drawbox=y=ih/PHI:color=0x000000@0.4:width=iw:height=48:t=max,'

from /Users/ACIDSTEALTH/.gem/ruby/2.3.0/gems/streamio-ffmpeg-3.0.2/lib/ffmpeg/transcoder.rb:112:in `validate_output_file' -
Tried building a hash from the command string and feeding that into the
transcodemethod.video = FFMPEG::Movie.new('input.mp4')
opts = {
'-vf' => {
format: 'yuv444p',
drawbox: {
y: 'ih/PHI', color: '0x000000@0.4', width: 'iw', height: '48', t: 'max'
},
drawtext: {
font: 'OpenSans-Regular,Sans', text: snap.title, fontcolor: '0xFFFFFF', fontsize: '24', x: '(w-tw)/2', y: '(h/PHI)+th'
},
format: 'yuv420p'
}
}
video.transcode('output.mp4', opts)I also tried a variation without the
-vfflag :video = FFMPEG::Movie.new('input.mp4')
opts = {
format: 'yuv444p',
drawbox: {
y: 'ih/PHI', color: '0x000000@0.4', width: 'iw', height: '48', t: 'max'
},
drawtext: {
font: 'OpenSans-Regular,Sans', text: snap.title, fontcolor: '0xFFFFFF', fontsize: '24', x: '(w-tw)/2', y: '(h/PHI)+th'
},
format: 'yuv420p'
}
video.transcode('output.mp4', opts)
These both produced an
output.mp4video file but the output file was unchanged from the input. There was no text overlay.Nothing I try seems to work. What am I doing wrong here ?

Unable to split audio using easy_audio_trimmer
27 juillet 2023, par Sana Wasimcan we use the easy_audio_trimmer package to split an audio ? I tried using the ffmpeg but it is conflicting with the above package and not work.


I tried splitting by using these functions and it gave an error at the FlutterFFmpeg() method and i cant find an alternative also the duration(filePath) in the command final durationResult = await flutterSound.duration(filePath) ; shows an error


Future<void> _splitAudio() async {
 setState(() {
 _progressVisibility = true;
 });

 // Get the application documents directory
 final appDocumentsDirectory = await getApplicationDocumentsDirectory();

 // Get the input audio file path
 final inputAudioPath = widget.file.path;

 // Get the output file names for the two parts
 final outputFileName1 = 'split_audio_part1.mp3';
 final outputFileName2 = 'split_audio_part2.mp3';

 // Get the output file paths for the two parts
 final outputPath1 = '${appDocumentsDirectory.path}/$outputFileName1';
 final outputPath2 = '${appDocumentsDirectory.path}/$outputFileName2';

 // Calculate the duration of the original audio
 final originalDuration = await _getAudioDuration(inputAudioPath);

 // Calculate the durations of the two parts
 final part1Duration = _startValue;
 final part2Duration = originalDuration - _endValue;

 // Construct the FFmpeg command to split the audio
 final ffmpeg = FlutterFFmpeg();
 final splitCommand = '-i $inputAudioPath -ss 0 -t $part1Duration -c copy $outputPath1 -ss $_endValue -t $part2Duration -c copy $outputPath2';

 try {
 // Execute the FFmpeg command to split the audio
 final int result = await ffmpeg.execute(splitCommand);

 if (result == 0) {
 setState(() {
 _progressVisibility = false;
 });
 debugPrint('Audio split successfully.');
 } else {
 setState(() {
 _progressVisibility = false;
 });
 debugPrint('Failed to split audio.');
 }
 } catch (error) {
 setState(() {
 _progressVisibility = false;
 });
 debugPrint('Error while splitting audio: $error');
 }
 }

 Future<int> _getAudioDuration(String filePath) async {
 final flutterSound = FlutterSound();
 final durationResult = await flutterSound.duration(filePath);
 return durationResult.inMilliseconds;
 }
</int></void>
