--- Comment #4 from Max Stepin <maxstepin at yahoo.com> ---
If segmentLength is big enough we might overshoot a little, and decode not just haltAtFrame but a few more frames after haltAtFrame.

It might potentially lead to a problem with clearFrameBufferCache().

I guess we need to find a way to stop precisely at haltAtFrame. 

There is something similar: decodingSizeOnly() case stops precisely at the header, I'll see if we can use this method.
