It is cross on Ubuntu.
You can get all ID3 meta-tags including the bitrate
Audio Bitrate : 128000
Running the command without any arguments gets you all the tags.
But -t should give you what you want.

I'm not really sure about MP3 streaming, but it seems likely to me that the bitrate information script to determine the bitrate, and query this information separately from the stream.

Will still run, but the AudioFile framework won't know about the bitrate property at all, and would.

* quality bitrate and copy it to your player..
The bitrate of your mp3 music collection so that the filesize can be dramatically reduced all ID3 tags with ease * advanced options: detailed bitrate settings, sample frequency etc.

Apple has included HTTP Adaptive Bitrate Streaming in the iPhone OS 3.0, in particular Safari handles this automatically.
I'd like to play with this in a low cost manner, but I expect it'll require a custom HTTP server in the worst case, and interesting...

If you have the file length in seconds.
The bitrate won't help you in calculating progress.

This might be a way too generic question, but what is the general approach for seeking within media files (video or audio of any kind/format) if the data has variable bitrate (VBR)?
It seems an easy thing to do if the stream has a constant bitrate (CBR...

OTOH, most video bit streams....
With a VOB file you get not only the bitstream itself, but also pointers to consecutive frames, so you can skip to another frame quickly and easily .
This is exactly why (for example) DVDs use VOB files instead of raw bitstreams .

Ffmpeg has an library interface - I know nothing about it, but maybe you could use that to get the information directly into your code?
