Christophe Gisquet	8e8ed57ea7	dnxhddec: remove unused qscale parameter Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	9 years ago
Christophe Gisquet	08a7510fca	dnxhddec: implement slice multithreading Around 3x speedup with 4 threads. Maybe more mb lines should be batched per thread, but that's good enough for a first try. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	9 years ago
Christophe Gisquet	dc218bd083	dnxhddec: parse and print adaptive color transform Indicates a YCbCr->RGB transform at the block level. Although nothing explicitly states it, this would assume the actual content is planar RGB. Currently unsupported, but the one sequence I found using it flagged every mb that way, actually meaning the content was YCbCr, and thus best left to the output format to decide what to do of it.

Christophe Gisquet	e4b7c3a9f2	dnxhddec: proper rule for interlaced mb flag It currently only applies to CID 1260, but this flag is dependent on a higher-level flag located in the header. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	9 years ago
Christophe Gisquet	e19ea0218a	dnxhddec: indicate colorspace It is supposed to only old BT.709 colorspaces. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	9 years ago
Christophe Gisquet	2801a1352d	dnxhddec: decode and use interlace mb flag This bit is 1 in some samples, and seems to coincide with interlaced mbs and CID1260. 2008 specs do not know about it, and maintain qscale is 11 bits. This looks oversized, but may help larger bitdepths. Currently, it leads to an obviously incorrect qscale value, meaning its syntax is shifted by 1. However, reading 11 bits also leads to obviously incorrect decoding: qscale seems to be 10 bits. However, as most profiles still have 11bits qscale, the feature is restricted to the CID1260 profile. The encoder writes 12 bits of syntax, last and first bits always 0, which is now somewhat inconsistent with the decoder, but ends up with the same effect (progressive + reserved bit). Partially fixes ticket #4876. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	9 years ago
