2018-08-30Revert "Loopfilter MultiThread Optimization"James Zern
This reverts commit dafe064289a917977439ab6f4f002b9946496084. Corrupted files may cause the decoder to hang as row progress in the loopfilter is used to progress each thread. BUG=webm:1558 Change-Id: I0674ce9af14d3fb7b2da8124e7b600616c8e734a
2018-08-27Rework enc/dec mismatch detectionJingning Han
The previous enc/dec mismatch detection assumes the previously reconstructed frame would always stay at frame buffer pool index at 0. It could hence cause certain delay in enc/dec mismatch detection when the immediate reconstruction frame is not yet propagated to index 0 in the buffer map pool. This change always keeps the latest decoded show frame buffer index and directly gets the reconstructed frame from encoder and decoder buffer pools to check for mismatch.

This commit adds a command line argument "--row-mt". Passing "--row-mt=1" will set the row_mt flag in the decoder context.

2016-06-21Add a hardware compatibility featurehui su
This commit adds an encoder workaround to support better compatibility with a non-compliant hardware vp9 profile 2 decoder. The known issue with this decoder is: The decoder assumes a wrong value, 127 instead of the correct value of 511 and 2047, for any assumed top-left corner pixel in UV planes for 10 and 12 bit, respectively. Such assumed top-left corner pixel is used for INTRA prediction when a real decoded/reconstructed pixel is not avalable, e.g. when it is located inside the row above the top row or inside the column left to the leftest column of a video image.
