| JCTVC-O0004 JCT-VC AHG report: HEVC conformance test development (AHG4) [T. Suzuki, W. Wan]
The ftp site at ITU-T is used to exchange bitstreams. The ftp site for downloading bitstreams is,
http://wftp3.itu.int/av-arch/jctvc-site/bitstream_exchange/
A spreadsheet to summarize the status of bitstream exchange, conformance bitstream generation is available in that directory. It includes the list of bitstreams, codec features and settings, and status of verification.
So far, 128 bitstreams were collected. Most of them were updated to the HM10 syntax. However, two bitstreams are still based on the older version of the spec. Those bitstreams must be updated based on the final spec of the HEVC, as soon as possible.
The generated bitstreams are available at
http://wftp3.itu.int/av-arch/jctvc-site/bitstream_exchange/draft_conformance/
The features and conformance point of each bitstream are summarized in the attached Excel sheet.
One relevant contribution was noted: JCTVC-O0084 (Editor's proposed draft text of HEVC conformance testing).
The AHG recommended to discuss the plan to collect missing bitstreams, and to continue to collect more bitstreams, especially for corner cases.
Some issues noted to be missing from the conformance test set included the output flag, LTRPs, and combinations of features.
It was remarked that a few of the bitstreams that have been collected have problems that have been identified, and have not yet been corrected.
It was noted that some of the available bitstreams do not obey the established conventions [doc num], such as file naming and MD5 checksum file formatting. It was agreed to produce an output document to capture and call attention to the guidelines.
The current status was discussed and updated. It was agreed to append a tabulated description of the current status in the output draft (study text status for WG 11 purposes).
