[-(26 + s->sps->qp_bd_offset / 2), (25 + s->sps->qp_bd_offset / 2)].

faf03ecba0 hevc: Remove useless clip 
The src buffer should only contain values in the interval
[0, (1 << BIT_DEPTH) - 1].

Since shift = (BIT_DEPTH - 5), src[x] >> shift must be in
the interval [0, 31], so no clip is needed.

a246d06fe0 hevc: clip pixels when transquant bypass is used 
The reconstructed picture should always be clipped (see section 8.6.5),
previously we did not clip coding units where
cu_transquant_bypass_flag == 1.

dd2d0039b6 vc1: Always reset numref when parsing a new frame header. 
Fixes an issue where the B-frame coding mode switches from interlaced
fields to interlaced frames, causing incorrect decisions in the motion
compensation code and resulting in visual artifacts.

9ecabd7892 h264: reset num_reorder_frames if it is invalid 
An invalid VUI is not considered a fatal error, so the SPS containing it
may still be used. Leaving an invalid value of num_reorder_frames there
can result in writing over the bounds of H264Context.delayed_pic.

7f0e81db3c h264: limit allowed pred modes in ff_h264_check_intra_pred_mode() to 3 
Higher modes are not allowed for 16x16/chroma, which is what this
function is used for. Otherwise this function would return 0 (vertical
prediction) for invalid higher modes, which could result in invalid
reads.
