vc2hqdecode appears to incorrectly read values within a bounded block whose last bit(s) 'dangle' off the end of the bounded block.
The following zip file contains a series of *.vc2 files containing bitstreams in which some bits within a value dangle off the end of a bounded block. Corresponding .expected files give the expected decoder output and .actual files give the actual (incorrect) output produced by vc2hqdecode:
Each test file contains test cases for values in either the Y, C1 or C2 components and tests one of the following cases of 'dangling' bits:
This bug is likely to result in picture corruptions in the event that a stream using dangling values is decoded. The corruptions are likely to be mild because they will typically impact a single HF component.
Ideally, special case handling of dangling values ought to be added to fix this bug to make this decoder compatible with encoders other than vc2hqencode.
