Christophe Gisquet	e54d7e4e8e	dnxhddata: Deduplicate cid 1256 chroma table CID 1256 is specified as using the same table for luma and chroma, which is the same as CID 1235 luma table. This is consistent with the format supposedly being RGB, although most sequences seem to actually be YCbCr-encoded.

Jeremy James	1fb63d6f43	dnxhddata: Deduplicate dnx100 tables Tables 1258 and 1259 were not zigzagged when added, so it was not possible to notice the equivalence. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>	10 years ago
Jeremy James	cc320296ab	dnxhddata: Fix cid 1260 luma and chroma tables These table was not zigzagged when added. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>	10 years ago
Joseph Artsimovich	bfe1cd80eb	dnxhddata: Fix 10-bit DNxHD quant matrices Convert them to zigzag order, as the rest of them are. When I was adding support for 10-bit DNxHD, I just copy-pasted the missing quant matrices from the spec. Now it turns out the existing matrices in dnxhddata.c were in zigzag order. This resulted in wrong quantization for 10-bit DNxHD. The attached patch fixes the problem by converting 10-bit quant matrices to zigzag order.

Jeremy James	428424fe75	dnxhddata: correct weight tables CID 1260 (as evidenced by incorrect decoding of a sample from ticket 4876) seems to use incorrect weight tables. It appears those tables were not zigzag-scanned. Apply zigzag on weight tables for new CIDs 1258, 1259, and 1260, and fix an incorrect chroma table for CID 1256. Fixes last issue from ticket #4876.

Michael Niedermayer	87a11db220	dnxhddata: Double frame_size for cid 1260 Despite '417792' being reported in the binary decoder, the buffer at encoding time needs to be bigger to avoid running out of space due to interlace handling.

Vittorio Giovara	fdd021884d	dnxhddata: Keep a single CID in the table names Use a comment to list the reused tables, since it's more flexible than a table name to keep information like this. The list will expand in later commits.	10 years ago
