Lego Mindstorms RSO Format
14 juillet 2010, par Multimedia Mike — GeneralI recently read a magazine article about Lego Mindstorms. Naturally, the item that caught my eye was the mention of a bit of Lego software that converts various audio file formats to a custom format called RSO that can be downloaded into a Mindstorms project to make the creation output audio. To read different sources, one might be left with the impression that there is something super-duper top secret proprietary about the format. Such impressions do not hold up under casual analysis of a sample file.
A Google search for "filetype:rso" yielded a few pre-made sample that I have mirrored into the samples archive. The format appears to be an 8-byte header followed by unsigned, 8-bit PCM. More on the wiki. If FFmpeg could gain an RSO file muxer, that would presumably be a heroic feat to the Lego hacking community.

Flutter video_compress and then ffmpeg trim video to 30s fails with endless logs
7 mars 2021, par Charles BassI 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
static Future<file> compressFile(File file) async {
 print('[COMPRESSING FILE]');

 String mimeStr = lookupMimeType(file.path);
 var fileType = mimeStr.split('/');

 if (fileType.contains("image")) {
 print('[COMPRESSING FILE] - file is image');
 String tempPath = (await getTemporaryDirectory()).path;
 String targetPath = '$tempPath/${DateTime.now().toIso8601String()}.jpg';
 return await compressImageAndGetFile(file, targetPath);
 } else {
 print('[COMPRESSING FILE] - file is video');

 final compressedVideoFile = await compressVideoAndGetFile(file);
 print('[VIDEO FILE COMPRESSED]');
 return await trimVideoGetFile(compressedVideoFile);
 }
 }
 
 
//! function to compress video
static Future<file> compressVideoAndGetFile(File file) async {
 print('[COMPRESSING VIDEO]');

 var result = await VideoCompress.compressVideo(
 file.absolute.path,
 quality: VideoQuality.DefaultQuality,
 deleteOrigin: true,
 );

 print('[COMPRESSED VIDEO TO]: ${result.file.path}');

 return result.file;
 }
 
//! function to trim video
static Future<file> trimVideoGetFile(File file) async {
 print('[TRIMMING VIDEO]');

 Directory appDocumentDir = await getApplicationDocumentsDirectory();
 String rawDocumentPath = appDocumentDir.path;
 String outputPath = rawDocumentPath + "/TRIMMED.mp4";

 final newFile = File(outputPath);

 if (await newFile.exists()) {
 await newFile.delete();
 }

 _flutterFFmpeg
 .execute(
 "-ss 00:00:00 -i ${file.path} -to 00:00:30 -c copy $outputPath")
 .then((rt) async {
 print('[TRIMMED VIDEO RESULT] : $rt');
 if (rt == -1) {
 throw Exception("Something went wrong when trimming the video");
 }
 });

 return File(outputPath);
 }</file></file></file>






Thank you in advance
