629fb5c46a flacdec: There is an even smaller FLAC frame size possibility.

5756bc7b02 flacdec: 10l to me. I miscalculated the smallest FLAC frame. It is 16
bytes, not 24.

5ef4fa87b3 flacdec: Add a check for small buffer size. This ensures reading as
much of the frame header as possible without excluding the smallest
possible FLAC frame.  It also fixes a false positive warning message
that was being emitted at the end of decoding.

6d08f6c911 100l, interplayvideo uses 8x8 blocks, so call the 8x8 put_pixels_tab function
instead of the 16x16 one. Seems to fix decoding on PPC.

2cc304215d Favor container packets that end after the first byte of the access
unit in fetch_timestamp(). This should make no difference for valid
streams but may help invalid ones, also its needed for future changes.

a4c7a5ea27 Call ff_fetch_timestamp() for mpeg1/2 when a picture start code is found instead
of calling it at the end of a frame with a large negative offset.
This significantly reduces the maximal distance in container packets between
the point where the first byte of the "access unit" was stored and where
we call ff_fetch_timestamp() thus reducing the constraints on our parser.
Also change the parser from next_frame_offset to cur, this is needed
because now the reference is from container packet start instead of
frame start. (i previously misinterpreted this as bug)
