阅读更多关于 Playing an ogg stream in iOS

问题 Has anyone played an ogg stream from iOS? What can I use without having to write my own decoder? I'm using Apple's AVPlayer to play the stream. This question has been asked as part of this thread: iOS online radio streaming questions but it hasn't been answered. 回答1: There is no built-in support for playing ogg files in iOS, however, the source code for ogg compression/decompression is readily available (from xiph.com). It is fairly straightforward to compile this code for iOS and use it in

问题 Do you know a class to merge two MP3 files using PHP? I've found nothing on Google. 回答1: If by merging, you mean placing one audio over the other, then please disregard this answer. If you dont want to re-encode the MP3s, you can probably just append them. I know this worked for MPEG movies, so I guess it could work for MP3s too.

I'm hoping I won't have to use libavcodec directly, as I imagine it will be far more complex than a one-line function to convert between formats. If FFmpeg can't be easily retrofitted to do this, is there perhaps another library based on it that does? I've heard of libvlc, but that seems to only expose a video playing

问题 EDIT: Incorporated the changed uv001's answer. I can only find that ICS 4.0 support decoding of FLAC, but encode. I need some encoder to convert wav to flac, but currenty I can't find it. I find there is a jFlac avaible , but I don't know how to use this library, just simply convert the files. Could anyone give me a hand on it? Today, I just some idea by myself, with using the JavaFlacEncoder. and it works for certain bitrates of WAV. I changed the value into a hard coding value in which it
