问题 I'm looking for a way to extract the audio part of a FLV file. I'm recording from the user's microphone and the audio is encoded using the Nellymoser Asao Codec. This is the default codec and there's no way to change this. 回答1: ffMpeg is the way to go ! It worked for me with SVN Rev 14277. The command I used is : ffmpeg -i source.flv -nv -f mp3 destination.mp3 GOTCHA : If you get this error message : Unsupported audio codec (n) , check the FLV Spec in the Audio Tags section. ffMpeg can decode

MP3: a way to get position in milliseconds for any given byte position?

问题 I've created a servlet which returns a stream (from an MP3 file) beginning at any given byte position requested by a client. This allows the client to start playback instantly at any given byte position without doing any local seek. Now, I've got a slider which visualises the progress. I'm using the the current byte position to update the slider. However, I'd also like to show the current position in seconds. This requires that the server can "convert" the current position in bytes to the

Google Chrome no longer plays certain audio files

问题 Since the update to v45, Chrome seems to no longer play select MP3 files. This is not across the board, and some other MP3 files still play. Chrome v44 displayed no issues and played all the files. This issue is common across many computers running various editions of Windows (in both 32 and 64 bit), and rolling back will allow the files to play. This however is not a viable solution for the client PCs, nor suitable going forwards. Upon inspecting the files themselves, I am unable to note any

ID3 tags with Swift

由 醉酒当歌 提交于 2019-12-30 01:01:06
问题 I'm looking for a way to modify ID3 tags with Swift. More specifically, I want to write the Album Art image to an mp3/m4a file. A Swift library would be the best, but I'll take anything that can be done natively in Swift. I don't want to rely on another language's library. I had a quick look at AVFoundation, but it looks like it's only for audio/video playback and conversion. This is about the closest I found from ID3 tags: https://developer.apple.com/library/mac/documentation/AVFoundation
