Presumably you mean that you see "N/A" in totem.

In this case, the decoder element did not report a bitrate, either because
nobody wrote code for the decoder to do so, or because the bitrate is variable
or not known.  Some bitstreams do not contain this information.

Reporting average bitrate over an entire file is nearly useless, since average
bitrate has very little correspondence to a constant bitrate.  I don't see much
use in spending developer time to provide "low value" information.  Also, this
bitrate would be for the file, not the audio or video stream.

It might make sense to report "bitrate: variable" and then provide periodic
statistics as to the instantaneous bitrate.  This would best be done with a
separate element in the pipeline that calculates and reports the statistics.

I'm closing this bug report, since it's not really a bug.  Feel free to open
bug reports on particular decoder elements that are doing a poor job at
reporting bitrates, preferably with patches.
