You cannot randomly cut a general h264 stream, this
does not necessarily work.
It is not possible to save a state of the decoder
to allow decoding such a randomly cut stream.
Either the stream allows to be cut ("intra-refresh"
or something similar, valid h264 streams without
I frames exist), in this case just feed frames
into the decoder until it returns frames.
Or the stream only contains one I frame and you
need this frame, then you can only start decoding
from the beginning of the stream.
