Multilang : améliorer l’interface pour les blocs multilingues
18 février 2011, parMultilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela. -

options_table : Remove a now unnecessary include of config.h
3 novembre 2016, par Martin Storsjöoptions_table : Remove a now unnecessary include of config.h
The include of config.h was added in 2012 in 1d9c2dc8, due to
the use of CONFIG_SNOW_ENCODER ifdefs within options_table.h.
When the snow codec was dropped later (in a0c5917f8 in 2013),
this include no longer served any purpose.options_table.h is included in builds for the host as well, when
building documentation. config.h should not be included in code
that is built for the host, since it can contain workarounds
for the target compiler/environment, like adding a missing define
of restrict, defining getenv(x) to NULL for environments that lack
getenv.The seemingly innocent include reordering in 2025d37871 broke
builds that have getenv(x) defined to NULL in config.h (Windows CE
and Windows Phone/RT), since libavcodec/options_table.h include
config.h, while libavformat/options_table.h end up bringing in
more system headers, and those system headers can contain a proper
definition of getenv, which clash with the getenv define in config.h.
This was avoided earlier as long as libavformat/options_table.h (or
avformat.h) was included before libavcodec/options_table.h.This fixes builds for Windows Phone/RT and CE.

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

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.
