• Installing ffmpeg in Ubuntu by using Chef fails by error of yasm version

  23 décembre 2014, par ironsand

  I want to install ffmpeg in Ubuntu14.04 by using chef.

  This is my config files for it.

  Berksfile

  source "https://api.berkshelf.com"
  
  cookbook 'apt'
  
  cookbook 'ffmpeg'

  nodes/ubuntu.json

  {
  
      "run_list": [
  
          "apt",
  
          "ffmpeg"
  
      ]
  
  }

  Then run knife solo cook ubuntu. It ends up with a error :

  STDOUT: Found no assembler
  
  Minimum version is yasm-1.2.0

  I understand the error. probably if I install yasm-1.2.0 manually, then the error will be fixed.

  But I want to install only by using chef. What can I do to solve the problem ?

• Flutter video_compress and then ffmpeg trim video to 30s fails with endless logs

  7 mars 2021, par Charles Bass

  I am trying to make a simple app in Flutter. A user can either take or pick a video and then upload it. However, I wanted to compress the video for storage purposes on firebase storage, and also trim it to only get the first 30 seconds.

  


  I am facing a very puzzling problem. I am able to compress the video, but with the resultant file, FFmpeg fails to trim it and I get endless logs which result in me having to stop the app and re-run. Alternatively, I am able to trim the video, but with the resultant file, I am unable to compress it getting the error :  Failed to open file '/data/user/0/live.roots.roots/app_flutter/TRIMMED.mp4'. (No such file or directory) PlatformException(error, java.io.IOException: Failed to instantiate extractor., null, java.lang.RuntimeException: java.io.IOException: Failed to instantiate extractor.

  


  This is my code below :

  


  


  


  //! function that controls file compression and trimming&#xA;static Future<file> compressFile(File file) async {&#xA;    print(&#x27;[COMPRESSING FILE]&#x27;);&#xA;&#xA;    String mimeStr = lookupMimeType(file.path);&#xA;    var fileType = mimeStr.split(&#x27;/&#x27;);&#xA;&#xA;    if (fileType.contains("image")) {&#xA;      print(&#x27;[COMPRESSING FILE] - file is image&#x27;);&#xA;      String tempPath = (await getTemporaryDirectory()).path;&#xA;      String targetPath = &#x27;$tempPath/${DateTime.now().toIso8601String()}.jpg&#x27;;&#xA;      return await compressImageAndGetFile(file, targetPath);&#xA;    } else {&#xA;      print(&#x27;[COMPRESSING FILE] - file is video&#x27;);&#xA;&#xA;      final compressedVideoFile = await compressVideoAndGetFile(file);&#xA;      print(&#x27;[VIDEO FILE COMPRESSED]&#x27;);&#xA;      return await trimVideoGetFile(compressedVideoFile);&#xA;    }&#xA;  }&#xA;  &#xA;  &#xA;//! function to compress video&#xA;static Future<file> compressVideoAndGetFile(File file) async {&#xA;    print(&#x27;[COMPRESSING VIDEO]&#x27;);&#xA;&#xA;    var result = await VideoCompress.compressVideo(&#xA;      file.absolute.path,&#xA;      quality: VideoQuality.DefaultQuality,&#xA;      deleteOrigin: true,&#xA;    );&#xA;&#xA;    print(&#x27;[COMPRESSED VIDEO TO]: ${result.file.path}&#x27;);&#xA;&#xA;    return result.file;&#xA;  }&#xA;  &#xA;//! function to trim video&#xA;static Future<file> trimVideoGetFile(File file) async {&#xA;    print(&#x27;[TRIMMING VIDEO]&#x27;);&#xA;&#xA;    Directory appDocumentDir = await getApplicationDocumentsDirectory();&#xA;    String rawDocumentPath = appDocumentDir.path;&#xA;    String outputPath = rawDocumentPath &#x2B; "/TRIMMED.mp4";&#xA;&#xA;    final newFile = File(outputPath);&#xA;&#xA;    if (await newFile.exists()) {&#xA;      await newFile.delete();&#xA;    }&#xA;&#xA;    _flutterFFmpeg&#xA;        .execute(&#xA;            "-ss 00:00:00 -i ${file.path} -to 00:00:30 -c copy $outputPath")&#xA;        .then((rt) async {&#xA;      print(&#x27;[TRIMMED VIDEO RESULT] : $rt&#x27;);&#xA;      if (rt == -1) {&#xA;        throw Exception("Something went wrong when trimming the video");&#xA;      }&#xA;    });&#xA;&#xA;    return File(outputPath);&#xA;  }</file></file></file>
