2011-02-04correct quantizer initializationJohn Koleszar
The encoder was not correctly catching transitions in the quantizer deltas. If a delta_q was set, then the quantizer would be reinitialized on every frame, but if they transitioned to 0, the quantizer would not be reinitialized, leading to a encode-decode mismatch. This bug was triggered by commit 999e155, which sets a Y2 delta Q for very low base Q levels. Change-Id: Ia6733464a55ee4ff2edbb82c0873980d345446f5

2011-02-02Delay auto key frame insertion in realtime configurationAttila Nagy
Whe auto keyframe insertion is enabled and conditions are right (scene change) the encoder can decide to insert a key frame and does a re-encoding. This can introduce extra latency. In RT mode we do not do the re-encoding of the current frame but force the next frame to key frame. Change-Id: I15c175fa845ac4c1a1f18bea3676e154669522a7

2011-01-31Removed prediction_error accumulationScott LaVarnway
from vp8cx_encode_intra_macro_block. prediction_error is used when deciding if a frame should be a keyframe. After reviewing this with Yaowu, it was pointed out that vp8cx_encode_intra_macro_block is only called for keyframes, so the accumulation is unnecessary.

2011-01-31Merge "Changed condition for using RD in Intra Mode"Adrian Grange
2011-01-28change the threshold of DC check for encode breakoutYaowu Xu
Previously, the DC check is to make sure there is no code-able DC shift for quantizer Q0, which has been verified rather conservative. This commit changes the criteria to have two components, DC and AC, to address the conservativeness. First, it checks if all AC energy is enough to contribute a single non-zero quantized AC coefficient. Second, for DC, the decision to skip further considers two possible scenarios: 1. There is no code-able 2nd order DC coefficient at all; 2 The residue is relatively flat, but the uniform DC change is very small, i.e. less than 1/2 gray level per pixel. Comparing to previous criteria, the new criteria is about 10% to 15% faster in encoding time with a very small quality loss. (threshold ~1000 and quality range 33db-45db) It should be noted that this commit enables "automatic" static threshold for encodebreakout if a non-zero small value is passed in to encoder.

2011-01-28Changed condition for using RD in Intra ModeAdrian Grange
The condition for using RD when selecting the intra coding mode for a MB is that the RD flag is set AND we're not in real-time mode. Previously the code used RD if either the RD flag was set OR we were not using real-time mode. Change-Id: Ic711151298468a3f99babad39ba8375f66d55a08

2011-01-28Adds "armvX-none-rvct" targetsTero Rintaluoma
Adds following targets to configure script to support RVCT compilation without operating system support (for Profiler or bare metal images). - armv5te-none-rvct - armv6-none-rvct - armv7-none-rvct To strip OS specific parts from the code "os_support"-config was added to script and CONFIG_OS_SUPPORT flag is used in the code to exclude OS specific parts such as OS specific includes and function calls for timers and threads etc. This was done to enable RVCT compilation for profiling purposes or running the image on bare metal target with Lauterbach. Removed separate AREA directives for READONLY data in armv6 and neon assembly files to fix the RVCT compilation. Otherwise "ldr <reg>, =label" syntax would have been needed to prevent linker errors. This syntax is not supported by older gnu assemblers. Change-Id: I14f4c68529e8c27397502fbc3010a54e505ddb43

2011-01-26Rationalize vp8_rd_pick_intra16x16mby_mode()Paul Wilkins
Use the function macro_block_yrd() to calculate error and distortion in keeping with what is done for inter frames. The old code was using a variance metric for once case and an SSE function for measuring distortion in the other case. The function vp8_encode_intra16x16mbyrd() is no longer used.
