[Live-devel] Dynamic buffer resizing (fNumTruncatedBytes)

That's correct.

No, because the choice of how to handle the 'truncated data' situation is best left up to the receiver.  As you noted, the data has been lost, but the receiver *may* then choose to allocate a larger-sized to use in subsequent calls to "getNextFrame()" (e.g., VLC does this), or it might not.

In any case, we're not going to change the signature to "getNextFrame()", because it's used throughout the code - not just in the couple of places you noted.

(It's possible that we'll completely change the way we handle buffers in some future revision of the software, but if that ever happens, it'll be a major, non-backwards-compatible revision.)
