• ffmpeg command to convert 720p to 1080p, 1440p, 2160p compatible with YouTube [closed]

  24 juin 2024, par Tendekai Muchenje

  I have a video that I created in Final Cut Pro. When i uploaded it to Youtube, it only maxes out at 720p. I would like it to have higher options like 1080, 1440 and 2160 even if the quality does not change. Maybe 2160 is impossible, but 1440p would be nice. I have tried this command, but the resulting file is unplayable, it only plays audio.

  


  ffmpeg -i Hey\ Girl.mov -vf scale=3840x2160:flags=lanczos -c:v libx264 -crf 13 -c:a aac -b:a 512k -preset slow hey_girl_hd.mov


  


  I am looking for a command that would make at least 1080 and 1440 work on YouTube. If 2160 can work, that would be great too. If it matters, here is all the info that ffprobe throws out about the file

• How to add subtitles using FFmpeg-kit ?

  17 novembre 2024, par Mohammed Bekele

  I'm running a Flutter app with Ffmpeg-kit package to burn a subtitle on a video. I have a words list with the timings and map that to generate an srt and ass file, but when executing this it didn't work.

  


  Firstly, here is how I generated the Ass file.

  


  Future<string> _createAssFile() async {&#xA;    String filePath = await getAssOutputFilePath();&#xA;&#xA;    final file = File(filePath);&#xA;    final buffer = StringBuffer();&#xA;&#xA;    // Write ASS headers&#xA;    buffer.writeln(&#x27;[Script Info]&#x27;);&#xA;    buffer.writeln(&#x27;Title: Generated ASS&#x27;);&#xA;    buffer.writeln(&#x27;ScriptType: v4.00&#x2B;&#x27;);&#xA;    buffer.writeln(&#x27;Collisions: Normal&#x27;);&#xA;    buffer.writeln(&#x27;PlayDepth: 0&#x27;);&#xA;    buffer.writeln(&#x27;Timer: 100,0000&#x27;);&#xA;    buffer.writeln(&#x27;[V4&#x2B; Styles]&#x27;);&#xA;    buffer.writeln(&#xA;        &#x27;Format: Name, Fontname, Fontsize, PrimaryColour, SecondaryColour, OutlineColour, BackColour, Bold, Italic, Underline, StrikeOut, ScaleX, ScaleY, Spacing, Angle, BorderStyle, Outline, Shadow, Alignment, MarginL, MarginR, MarginV, Encoding&#x27;);&#xA;    buffer.writeln(&#xA;        &#x27;Style: Default,Arial,40,&amp;H00FFFFFF,&amp;H000000FF,&amp;H00000000,&amp;H80000000,1,1,1,1,100,100,0,0,1,1,1,2,10,10,10,1&#x27;);&#xA;    buffer.writeln(&#x27;[Events]&#x27;);&#xA;    buffer.writeln(&#xA;        &#x27;Format: Layer, Start, End, Style, Name, MarginL, MarginR, MarginV, Effect, Text&#x27;);&#xA;&#xA;    // Write events (subtitles)&#xA;    for (int i = 0; i &lt; widget.words.length; i&#x2B;&#x2B;) {&#xA;      final word = widget.words[i];&#xA;      final startTime = _formatAssTime(word[&#x27;startTime&#x27;].toDouble());&#xA;      final endTime = _formatAssTime(word[&#x27;endTime&#x27;].toDouble());&#xA;      final text = word[&#x27;word&#x27;];&#xA;&#xA;      buffer.writeln(&#x27;Dialogue: 0,$startTime,$endTime,Default,,0,0,0,,$text&#x27;);&#xA;    }&#xA;&#xA;    await file.writeAsString(buffer.toString());&#xA;    return filePath;&#xA;  }&#xA;&#xA;  String _formatAssTime(double seconds) {&#xA;    final int hours = seconds ~/ 3600;&#xA;    final int minutes = ((seconds % 3600) ~/ 60);&#xA;    final int secs = (seconds % 60).toInt();&#xA;    final int millis = ((seconds - secs) * 1000).toInt() % 1000;&#xA;&#xA;    return &#x27;${hours.toString().padLeft(1, &#x27;0&#x27;)}:${minutes.toString().padLeft(2, &#x27;0&#x27;)}:${secs.toString().padLeft(2, &#x27;0&#x27;)}.${(millis ~/ 10).toString().padLeft(2, &#x27;0&#x27;)}&#x27;;&#xA;  }&#xA;</string>

  


  Then I used this command which was the official way of adding ass file to a video.

  


    String newCmd = "-i $videoPath -vf ass=$assFilePath -c:a copy $_outputPath";


  


  Yet when executing this command it did not work. However I changed it to this command

  


  String newCmd = "-i $videoPath -i $assFilePath $_outputPath";


  


  Well, that code works but the styling is not being applied. So I tried yet another command to filter and position the ass file.

  


  String newCmd = "-i $videoPath -i $assFilePath -filter_complex \"[0:v][1:s]ass=\\an5:text='%{event.text}',scale=iw*0.8:ih*0.8,setdar=16/9[outv]\" -map [outv] -c:a copy $_outputPath";


  


  This made it even worse, because the app crashed when I ran this. Also there is a log for this command before crashing

  I tried the normal command in my local machine on Windows, and this is what I used

  


  ffmpeg -i F:\ffmpeg\video.avi -vf subtitles='F\:\\ffmpeg\\caption.srt':force_style='Fontsize=24' F:\ffmpeg\new.mp4


  


  As you can see above when subtitles are used it had an extra backslashes for each path and a pre backslash after the partition letter. But I don't know if this does apply for android devices. How can I make sense of this ?

  Originally, I was trying to add a subtitle to in.mkv, but I keep encountering this error. When I add the subtitle to another MKV file, it works fine, so I believe the problem lies with in.mkv.

  


  Troubleshooting

  


  Output only video stream produce the same error :

  


  ffmpeg -i in.mkv -map 0:v:0 -c copy out.mkv


  


  Output only audio stream works fine :

  


  ffmpeg -i in.mkv -map 0:a:0 -c copy out.mkv


  


  Output as mp4 got no error, but the output file is unplayable :

  


  ffmpeg -i in.mkv -c copy -strict -2 out.mp4


  


  Re-encoding works fine :

  


  ffmpeg -i in.mkv -c:v libx265 -c:a copy out.mkv


  


  How can I fix the video stream in in.mkv so that I can add a subtitle stream and remux the file without re-encoding the video ? Any insights or suggestions on handling this error would be greatly appreciated.
