id3-tag

问题 I started reading mp3-files in c++. All went well until I read the specs of the ID3-Tag. There is some information in the ID3v2-Header about its size stored in so-called Synchsafe Integers. That is a four-byte integer where the most significant bit of each byte is set to zero. I found out how to convert it to an ordinary integer, but I cannot stop asking myself why an integer value is stored in such an unnecessarily complicated way. I hope there is someone who can tell me why it is stored

问题 I'm trying to get ID3 tags from a bunch of mp3 files in my project. AudioFileGetProperty(audioFile, kAudioFilePropertyInfoDictionary, &size, &metadataDictionary); If the tag doesn't contain cyrillic symbols, the output looks OK on the device. However I sometimes get values like this one: album = "\U00ce\U00f2\U00ea\U00f0\U00fb\U00f2\U00ee\U00e5 \U00d0\U00e0\U00e4\U00e8\U00ee 102.5FM"; "approximate duration in seconds" = "260.623"; and it leads to distorted symbols display (http://d.pr/i/X9wG)

问题 static void Main(string[] args) { FileStream fs = File.Open(@"C:\Skrillex - Rock n' Roll (Will Take You to the Mountain).mp3", FileMode.Open); BinaryReader br = new BinaryReader(fs); byte[] tag = new byte[3]; byte[] version = new byte[2]; byte[] flags = new byte[1]; byte[] size = new byte[4]; byte[] frameId = new byte[4]; byte[] frameSize = new byte[4]; byte[] frameFlags = new byte[2]; br.Read(tag, 0, tag.Length); br.Read(version, 0, version.Length); br.Read(flags, 0, flags.Length); br.Read

问题 i am trying to read bpm embedded in mp3 file like this one : i have tried using Windows.Storage.FileProperties.MusicProperties but it only contains title, singer, etc. it can't read the bpm i showed before. im looking into https://taglib.github.io/ they seems not having such function too. is there any workaround to this? 回答1: When you've loaded your music file into a StorageFile, you'll want to place a similar call in your code like this: var fileProps = await file.Properties

问题 Im making my own mp3 tagger, and everything is fine so far. Although im stuck reading the album art tag. I would like to know how to display the cover in a C#.NET picture box, but everything iv seen about that particular tag is confusing me. I know i can get tags from files like this txtAlbum.Text = currentFile.Tag.Album; but all i need to do is grab the picture from the file and whack it in a picturebox. Then i would like to know how to write a picture (jpg, png) into the file and overwrite

Is there a library for reading and writing ID3 tags to an MP3 in C#? I've actually seen a couple when searching, anybody using any that can be recommended? 回答1: Taglib# is the best. It's direct port of the TagLib C library to C#. To install TagLib#, run the following command in the Package Manager Console in

问题 I need to be able to at very least read and preferably write id3 tags connected to an mp4 video file. I've looked into using getId3() but it's got so many functions that finding those applicable to mp4 video files is difficult and the write demo files don't work on mp4 files 回答1: ID3 tags, as such, are only generally used on MP3 streams. I believe that MPEG 4 uses its own metadata format (within the meta atom). For details, see http://atomicparsley.sourceforge.net/mpeg-4files.html. 来源： https:
